Usually the leaning liftarm “almost” fits. </p> <p><a href="http://lh5.ggpht.com/-zIHaa5UeMCc/UydYPiVPlPI/AAAAAAAAEHM/XRBc72VsCvI/s1600-h/image%25255B11%25255D.png"><img title="image" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; float: none; padding-top: 0px; padding-left: 0px; margin-left: auto; border-left: 0px; display: block; padding-right: 0px; margin-right: auto" border="0" alt="image" src="http://lh4.ggpht.com/-7Uw0M7ub5cU/UydYQdVjJsI/AAAAAAAAEHQ/_KBeb-1nr8E/image_thumb%25255B7%25255D.png?imgmax=800" width="257" height="381"></a></p> <p>I translated the issue into a mathematical problem. The base is of course a right triangle with the condition that all sides must be an integer. The phenomenon is called Pythagorean triples. (google it). I found the following triples especially interesting for the context of Lego.</p> <p>3-</td><td width="64">4-</td><td width="64">5<br>6-8-10<br>5-12-13</p> <p>Then I realized that Lego also “supports” “half stud” constructions which also enable the following combinations:</p> <p>1,5-2-2,5<br>2,5-6-6,5</p> <p>Note that the numbers above corresponds to the length between the first and last hole in a liftarm. To translate the length into the number of holes of the liftarms you have to add one (1).

I left my "dark ages" during the summer of 2010. Since then I have recurrent periods where I build a few hours every week. However, within those I periods, I find myself completely stuck.</font> In this article I will give you my best tricks for fluent building!</p> <a name='more'></a> <p><font size="2">I decided to deal with this and started to analyze and improve the work process of building MOC:s. The main goal has been to make the building more fluent and enjoyable. </font> <p><font size="2">You get stuck when you just don't know how to continue or you have too many options to solve a problem, but have no idea which would be the best with respect to the rest of the model. </font> <p><font size="2">To ease such dilemmas and making the building more fluent I have thought out a few techniques, some apparent and some maybe less apparent. The following techniques have prove efficient:</font> <p><font size="2">- Get the goals straight<br>- Modularize<br>- Iterate!<br>- Give up</font></p> <p><strong>Get the goals straight</strong></p> <p>This includes questions like: What scale should the model have (and what measurement does that imply)? What functionality should the model have? Which of them should be motorized? Preferably you should write the goals down before you start building. <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEikqvmPRwV0CBpuhsi3qS6yjgu9SckWOzJrt_O5p8dR8b1_Y2PQFDTU5NUm-oHULUVT0vJhRpkCLUwPnRin4QrSpxtyceqqEbX7FJ1EhFiJJULjtzKNGGkqWH-q7nunGn9b56YHnuI25PT2/s1600-h/Figure1%25255B4%25255D.png"><img title="Figure1" style="border-left-width: 0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; padding-top: 0px; padding-left: 0px; display: inline; padding-right: 0px; border-top-width: 0px" border="0" alt="Figure1" src="http://lh4.ggpht.com/-WY3AIr389cc/Ux3iiNSqzrI/AAAAAAAAEGE/p_DHG9VC-lc/Figure1_thumb%25255B2%25255D.png?imgmax=800" width="363" height="197"></a> <p><em>My goals for my forwarder model</em></p> <p><strong>Modularize</strong></p> <p>When the goals, functionality, scale and measurements are set, break the model down into natural modules that can be developed relatively independent from each other. Typical examples are axles, engines, liftarms etc. Determine which module will be the hardest to build and start with that. It will give you on hand whether the model is at all possible to build in the chosen scale.</p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi9poLrSinmwFHYkimpUinP5IGFRihnXQDLsNm-jxn08n3qH0SreehGBeTeQ7FX7lnPs4SbXDfV8_dihgmFRey3RWKr4RL7BeBmPWOyhS3Upeu45nYiDG1f_bJVGC3dwbkTPnBjIUdRnOzA/s1600-h/Figure2%25255B4%25255D.png"><img title="Figure2" style="border-left-width: 0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; padding-top: 0px; padding-left: 0px; display: inline; padding-right: 0px; border-top-width: 0px" border="0" alt="Figure2" src="http://lh3.ggpht.com/-6MV9c1gXrwo/Ux3ijFb5DdI/AAAAAAAAEGU/UvsYmUt_UOA/Figure2_thumb%25255B2%25255D.png?imgmax=800" width="531" height="409"></a></p> <p><em>Some of the independently developed modules for my current project</em>.</p> <p><strong>Prototype</strong></p> <p>Focus on getting a working prototype with the most important functionality as fast as possible. Continue building even if you feel that you don't always get the best solution. A bad solution will lead you to a better solution much faster than not building at all. Furthermore, what seems to be an excellent solution at one point, often has to be abandoned later because it won't work with the design of the rest of the model. Through this method you will find such limitations much faster. <p>When the first prototype is ready, you can easily see which solutions are worth keeping and which are not. It will probably also tell you quite apparently what changes are needed. In this way, you don't have to disassemble the entire model 10 times just to make a slight change in the inner core of the model. <p>Getting a working prototype early in the process will also give you valuable input on where to put volume consuming parts such as the IR receivers and the battery pack. <p><strong>Iterate!</strong> <p>If you have enough pieces, start building a new version of the model from scratch while keeping the previous prototype intact. In that way you can easily rebuild the parts of the model you are happy with. You will be surprised how fast you will have the next prototype ready, and how much better than the first one it will be. I usually rebuild a model entirely 4-7 times until I am satisfied with the scale, design and functionality. <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOEw7vkQwRC6KS-7SWfEy9GGtRY_uiYd6dF8Hvt_Q5o-2aO1jovvt7zTdBsWR-oRfPak8IxAt_tOq2TZzqtmWZ-Oy4VNOnIe4HO6Hz9nd3eqs2n5BDIuAHDvc5xA-ZciWOqxJhQt32ldwE/s1600-h/Figure3%25255B4%25255D.png"><img title="Figure3" style="border-left-width: 0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; padding-top: 0px; padding-left: 0px; display: inline; padding-right: 0px; border-top-width: 0px" border="0" alt="Figure3" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiGnoTluXHcpl0J9M-Dm2vTz0HNSryyPzb0zXxeYcLN1LidJHS1bTwzPY3FbMMwOAmCBsKTmQy7bqCqiMnvj3AZHp3QHcNos8uZw85lPFZuDPFIkCWeM0KAKUSlNVkV9ABPJx9SfU5kdBqM/?imgmax=800" width="540" height="416"></a> <p><em>Second prototype of my current project.</em></p> <p><strong>Give up</strong> <p>This one is optional.

The problem is that the steering ”speed” will vary over the steering ”cycle” when only using a single LA. As a result, when using double LA:s, there will tensions, that might be large enough to engage the built in clutches in the LA:s. However, depending on how you choose your ”geometry”, this problem can be reduced. This video shows one example of a geometry that will work fairly well, using the mini LA:s. It has been tested in vehicle up to 70 cm / 2 kg. <p> </p> <div id="scid:5737277B-5D6D-4f48-ABFC-DD9C333F4C5D:fbb88c96-9b42-4675-9207-01d10ab91d9b" class="wlWriterEditableSmartContent" style="float: none; padding-bottom: 0px; padding-top: 0px; padding-left: 0px; margin: 0px; display: inline; padding-right: 0px"><div id="7625fd25-0b78-4a5b-b5dd-c578306f2f34" style="margin: 0px; padding: 0px; display: inline;"><div><a href="http://www.youtube.com/watch?v=7Mxe8iLtQik" target="_new"><img src="http://lh6.ggpht.com/-bATqTOc7HaA/UtFzkrSSjYI/AAAAAAAAEFM/qRtpfZg67Vw/video793e73f4c7c4%25255B6%25255D.jpg?imgmax=800" style="border-style: none" galleryimg="no" onload="var downlevelDiv = document.getElementById('7625fd25-0b78-4a5b-b5dd-c578306f2f34'); downlevelDiv.innerHTML = "<div><object width=\"540\" height=\"303\"><param name=\"movie\" value=\"http://www.youtube.com/v/7Mxe8iLtQik?hl=en&hd=1\"><\/param><embed src=\"http://www.youtube.com/v/7Mxe8iLtQik?hl=en&hd=1\" type=\"application/x-shockwave-flash\" width=\"540\" height=\"303\"><\/embed><\/object><\/div>";" alt=""></a></div></div></div> JHhttp://www.blogger.com/profile/07036544908546871140noreply@blogger.com0tag:blogger.com,1999:blog-8871129855859111403.post-4474557052766075792014-01-03T17:19:00.001+01:002014-01-03T17:19:09.642+01:00Bogie Axle with Leaf Spring Suspension<div id="scid:5737277B-5D6D-4f48-ABFC-DD9C333F4C5D:440cd1d4-5037-448b-8c43-0918a6dd5e8f" class="wlWriterEditableSmartContent" style="float: none; padding-bottom: 0px; padding-top: 0px; padding-left: 0px; margin: 0px; display: inline; padding-right: 0px"><div id="b5d9b24c-65a9-44ff-ab66-01fa68429880" style="margin: 0px; padding: 0px; display: inline;"><div><a href="http://www.youtube.com/watch?v=GqWdeH5qjd8" target="_new"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi69E6Rf7eAtycXnKf6FOKLXrcPyvGjFK12A4-fcBMMPkJhHDpvUSU4GteElSXx6BspuU9TpWEkXcT8u1VbFrMp1iwoxX6PjJkBhKy4XR6KCBWvUCOycEFVegg6zQyLveoZDfb_OdobmxCW/?imgmax=800" style="border-style: none" galleryimg="no" onload="var downlevelDiv = document.getElementById('b5d9b24c-65a9-44ff-ab66-01fa68429880'); downlevelDiv.innerHTML = "<div><object width=\"448\" height=\"252\"><param name=\"movie\" value=\"http://www.youtube.com/v/GqWdeH5qjd8?hl=en&hd=1\"><\/param><embed src=\"http://www.youtube.com/v/GqWdeH5qjd8?hl=en&hd=1\" type=\"application/x-shockwave-flash\" width=\"448\" height=\"252\"><\/embed><\/object><\/div>";" alt=""></a></div></div></div> JHhttp://www.blogger.com/profile/07036544908546871140noreply@blogger.com0tag:blogger.com,1999:blog-8871129855859111403.post-80863333544348390392013-08-10T17:24:00.001+02:002013-08-10T17:24:05.040+02:00Telehandler, v2<p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjN6V5vg3uqsMjMFhxr-KU7HoJ-ZT72KErrcPNVRGIE44pRg-5iPMfDKls8D3fqwSVtRaIVH-YZZAcGZy1OMW280ffLLESvzAKVntkYrSw_VTiorIdhC0yO8W5VojAH6x7ykwOaBL5x-aMH/s1600-h/IMG_2650%25255B5%25255D.jpg"><img title="IMG_2650" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; float: none; padding-top: 0px; padding-left: 0px; margin-left: auto; border-left: 0px; display: block; padding-right: 0px; margin-right: auto" border="0" alt="IMG_2650" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhPmF9iI1aoESMSDR8fUW62UwNsiMGXWh5YUtei-MluK7bgupyaWSt9giyMjmwWgDBs2W0JDp6Tr-YhFwEvoz-UfLOsbI4TVEJV_wR1bHa6yPULUdv2hkP4zR9U1XhvqLi69ffLUuvQVaSs/?imgmax=800" width="513" height="368"></a>I was not really happy with the first version of my <a href="http://www.jh-create.com/2013/02/telehandler.html" target="_blank">telehandler</a>, the design was nice but it performed quite badly, especially the weak propulsion and poor suspension. For some reason the tires almost tore off the axles when it drove a meter or so and it looked like the suspension was really weak, which it wasn’t. </p> <p>With the Grand Prix Racer (42000) set a new suspension system was introduced. I decided to have another go at building a Telehandler. I tried to keep the design as far as possible but reworked the entire chassis and used a PF L-motor for propulsion and the PF Servo for steering. </p> <p>The improvements:</p> <ul> <li>Stronger motor for propulsion <li>The chassis is two studs thinner <li>Completely reworked suspension <li>Almost twice as long telescopic boom </li></ul> <p><a href="http://www.jh-create.com/2013/05/pendular-steering-with-differential.html" target="_blank">Here</a> is a specific blog entry regarding the suspension. </p> <p><strong>Functionality</strong> </p> <ul> <li>4WD, PF L-motor <li>4 wheel steering, PF Servo Motor <li>Boom life, L-motor <li>Telescopic boom, M-motor <li>Bucket tilt, M-motor <li>Quick coupler <li>Pendular rear axle</li></ul> <p><a href="http://lh4.ggpht.com/-D5D8rE0qHZo/UgZbD3NuZ7I/AAAAAAAAD8M/4NtkeOftDDo/s1600-h/IMG_2460%25255B6%25255D.jpg"><img title="IMG_2460" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; float: none; padding-top: 0px; padding-left: 0px; margin-left: auto; border-left: 0px; display: block; padding-right: 0px; margin-right: auto" border="0" alt="IMG_2460" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmKUr6gSuT_XkPzTvRaoyxPZ_JWv2CTfvVXxysEpwsiNbv624lo4PFEUJ2VjKM75KiyU6Q2T58Nvd9CqR5qMU68h6j2KYpYpTwn-SPZEn8pHqOVKwehkzOGIy5vV8LHKPIkvNIqMAOASFz/?imgmax=800" width="555" height="438"></a></p> <p>I am really proud about how small but still robust I could make the chassis. In the picture you can see the entire chassis housing:</p> <ul> <li>2x PF L-motor <li>1x PF M-motor <li>1x PF Servo motor <li>1x Battery Pack <li>3x PF IR Receivers </li></ul> <p>However, It performed almost worse than the first version and I can’t get why. The tires do everything they can to rip apart which in turn affects the steering and propulsion. I am almost in doubt whether it is possible to build a 4 wheel driven and steered chassis with pendular suspension.. </p> <p>More pictures are available in the youtube clip. </p> <div id="scid:5737277B-5D6D-4f48-ABFC-DD9C333F4C5D:ce317d45-6941-4bd2-98a0-fcd26e0d6e0d" class="wlWriterEditableSmartContent" style="float: none;

and robust wheel loader still small enough to use the Lego 32030 bucket. </p> <p><strong>Datasheet</strong></p> <ul> <li>Propulsion: 4WD (PF XL motor)</li> <li>Steering: Articulated (2x Mini LA with PF M motor)</li> <li>Transmission: Mechanical </li> <li>Lift capacity: >500 g</li> <li>Scale: 1:27</li> <li>Length: 37 cm (without bucket)</li> <li>Height: 18 cm</li> <li>Width: 14 cm</li> <li>Weight: 950 g</li></ul> <p>The main problem was to fit the liftarm between the front wheels and still make the model less or equally wide as the bucket (140 mm).</p> <p> <a

the chassis. The frame houses the rear differential and is pendular. The U-joint for the drive trains spins as fast as the motor which greatly reduces the torque.</p> <p>I am very happy with the sort of “V-shaped” drive train for the mini linear actuators used for the frame (articulated) steering. All-in all I managed to hide <br>- 1x PF XL motor<br>- 1x PF L motor<br>- 2x PF M motor<br>- 2x PF IR receivers<br>- 1x PF Battery box (the large on)</p> <p>..in a chassis only marginally larger than the Lego 8265 set. The only things that slips under torque is the linear actuators. The drive train can bare the torque until the XL motor stalls.<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgN7L1ZD7snEE9WoUYbpHpLQnS1eSXxQVN8G7IGRitEhCIF9fe8JN0i0-XPqTOzUBnpZQ3tq68l-Hxfmd_qKdiYK0DhkXl1srPE75DktJcOBMlPVfM7rasxIiMUg-g2KBdcwF5HtYRzSz-K/s1600-h/IMG_1577%25255B5%25255D.jpg"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: block; float: none; margin-left: auto; border-top: 0px; margin-right: auto; border-right: 0px; padding-top: 0px" title="IMG_1577" border="0" alt="IMG_1577" src="http://lh4.ggpht.com/--XeIqYAf9bc/UTz9mupNAaI/AAAAAAAADlE/1-GErvVxksk/IMG_1577_thumb%25255B3%25255D.jpg?imgmax=800" width="271" height="390"></a></p> <p>The front part of the chassis.

In real frontloaders the quick coupler is very close to the front axle in order maximize lifting power without the machine tipping over. In order to achieve that in my model I used the frame from the steering ball joint instead of the ordinary 5x7 frame typically used around the differential. </p> <p><a href="http://lh3.ggpht.com/-99Rrwq7-u40/USCf0H325PI/AAAAAAAADfM/hg4QBl4XPv8/s1600-h/IMG_1186%25255B4%25255D.jpg"><img style="background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="IMG_1186" border="0" alt="IMG_1186" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhiCCYHXqPMtmV0o7S0OqJq9HfK42p0LY6e9N9z8d1CYbMUztaoJjjrx5-zeNT-ICmuj5SCTunB8n4-xCgT29NTooDXdHWPKC3-qVBNa6jtgi2LeL9TOoxW76Dl6ImX90F7uChUdd0eyn4f/?imgmax=800" width="539" height="415"></a></p> <p>The rear part with the pendular suspension. The L motor is for lifting the boom. The clutch gears enables two functions over one axle, in this case used to transfer steering and drive to reach the rear axle. <br></p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQx5Q09Xxfr2-7mMyYxNlkkqsliyYym41hs0BtPbknNw8Ap6ON5Iy9s7A_Py1GLgqvnWxLqsK6U_qaXy95LcXPrF5Xcoidl6QjiVfN-WBr85eZKyNPhrDIHTWZNnQkfDOizywp8RzoTrU_/s1600-h/IMG_1190%25255B4%25255D.jpg"><img style="background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="IMG_1190" border="0" alt="IMG_1190" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEggdDxNHWuCssVGvoghtfrIm1FeVWFZsIE_M99qVn_UQucK5q-Td58HgCKbZnxbFu1a9fYbR5NGCbhurGBppskOC9xG8AVM-Sq4UxC3zf_pP_xKPK7ucm03zyQa053MbyZjrzVrz-W_khRy/?imgmax=800" width="531" height="221"></a></p> <p>The chassis almost complete.

second, the rear wheels’ steering is very inaccurate since the steering transmission passes two “pairs” of 8-tooth gears along the way. </p> <div style="padding-bottom: 0px; margin: 0px; padding-left:

However it did become a lot stronger and it slips easily on most surfaces. </p> <p>Still, making a conventional tractor with pendular suspension, three point hitch and and PTO is truly hard without interfering with the design, it is simply very little “volume” available to hide everything. Also, the model can only be as big as the biggest wheels available will allow. Below you can see the final chassis housing 2 XL motor, 1 M-motor, 1 servomotor, 2 IR Receiver, a battery pack and 1.4m of wire. </p> <a name='more'></a><a href="http://lh3.ggpht.com/-hlDTn9bFb5E/UPGtBeqgKQI/AAAAAAAADTw/Q6Fx84zCjaI/s1600-h/IMG_1446%25255B4%25255D.jpg"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="IMG_1446" border="0" alt="IMG_1446" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEglDTH4mG1CrFu2Fb_8oo9G73IQoQ3_kWDjG6Dx4PEWVnYx3-sq2bH-9O3PNF-JgAQpGPj5_f1gzYqu2ymPD4du7dOtoBHLMWaGO_qF6y5gGSF50cIyjfP5ZF8pXOp2AqPIw5cnokF8sDG8/?imgmax=800" width="550" height="424"></a> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgIMgiLsNGlmEnRJNsZH7pwCsBvM3lOtxn53Jvgr8ZmqhjBxefkxledmGYOtrMnXYo2Fw4eMrM3obPonaL8zmj00LzS6Iiw05mW0sD3khFgNIBMeU3g1NV0B7T9TlHhyphenhyphen2ShU26KeZAY_pN8/s1600-h/IMG_1442%25255B4%25255D.jpg"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top: 0px; border-right: 0px; padding-top: 0px" title="IMG_1442" border="0" alt="IMG_1442" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiyT3fBBtdqZfqnq7fEh2U77QExen4KgoubsvnqIEqiaKFFuR_u291aZFBhSXU7VcXkxL-TVq3g8EpjwpbxYXd5Lb24WUCBQJ92igQVlYvMb_nhx4hlQu2e4lzKau89MnIqNirYRl7apTAE/?imgmax=800" width="551" height="425"></a></p> <p>The chain, worm gear and clutch gear is for lifting the three pint hitch.

Factors such as weight, wheel size and not least, articulated steering, put a lot of force on the bogie so it needed to be very stable, but at the same time not to wide in relation to the 14,5 scale. But I am very happy with the final design, although each bogie contains more than a 100 pieces. </p> <p align="left"> </p> <p align="center"></p> <p align="center"></p> <p align="center"></p> <p align="center"></p> <p align="center"></p> <p align="center"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgvyTl0KpywF56dsM8AzebXX-6ajJwdh4hsth0CTs29CfQtqgLWUC8YnT9liTASkNWSkiA6u4HtmZQKFhDvdmcGXK9IqqhcYCu-Hf4j9f1q9B6-5z4i-je01VV28D97tEHa4lvmb-tbQZvV/s1600-h/IMG_5007%25255B3%25255D.jpg"><img style="background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="IMG_5007" border="0" alt="IMG_5007" src="http://lh5.ggpht.com/-xUByTR7ZAiA/UF8yYDJNRiI/AAAAAAAAC9I/WnC1IPIDuGY/IMG_5007_thumb%25255B1%25255D.jpg?imgmax=800" width="473" height="577"></a></p> <p align="left">The grapple. It was important for it to be quite strong in order to actually be able to pick up small, but real, logs from the terrain. The grapple is powered by a PF M motor placed in the crane base. By five U-joints the drive train reaches the grapple, without limiting the crane’s movement range and angles. The grapple is rotated by a micro motor turning the turntable. The grapple is attached to the crane in the same way as a real crane making it able to swing in two dimensions. </p> <p align="left"> </p> <p align="center"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6QJk8vlckGih1KGkEMYfUu-supzi1eauNBc_Qgxp1HGFI4SnIURoxwYOYA4XjaV-ZtFztT_PP6X6w80L6Z2tKQ52XWbFczMcibe-9gfIyZIZ0XUuwmNn0xnBDgpZGf1K4mg46ElMI_XMS/s1600-h/IMG_5035%25255B4%25255D.jpg"><img style="background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="IMG_5035" border="0" alt="IMG_5035" src="http://lh3.ggpht.com/-9WvFXxzC3bI/UF8yaG4bAVI/AAAAAAAAC9Y/X3EfIf4EtIE/IMG_5035_thumb%25255B1%25255D.jpg?imgmax=800" width="488" height="343"></a></p> <p align="center"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9T0eNVwPUNfxs-uOhztMCq13OJwo_UpNSIL1PqbBFtSmmo52qMRNhTuFjnib4M57jFAkZuBYIGG6y3eYrFNN3A_UI7I5FLPG4-xVCIU1EN9jlkoW8XUtTct7770ZueVMuzJx2ik-F9vt4/s1600-h/IMG_5050%25255B3%25255D.jpg"><img style="background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="IMG_5050" border="0" alt="IMG_5050" src="http://lh4.ggpht.com/-C-diEQ4P-NA/UF8yb0B5M2I/AAAAAAAAC9o/X6Ckb_DPJQ0/IMG_5050_thumb%25255B1%25255D.jpg?imgmax=800" width="497" height="386"></a></p> <p align="left">The remote control.

To start with I looked around, primarly on Youtube to get inspiration. Actually there weren’t many good Tractor MOC:s out there, especially conventional tractors (those with bigger rear wheels).</p> <p>My objectives for the MOC was:</p> <a name='more'></a> <ul> <li>“Conventional” <li>4WD <li>Steered front axle with pendular suspension <li>Three point hitch <li>PTO (Power Take Out) <li>Correct scale and proportions </li></ul> <p>Most other tractor MOC:s primarly lacks my last objective, typically the wheels are way to small in respect to height and length. This is perhaps due to the fact that it is, even when using the biggest Lego wheels available, there is still not so much room fitting all the motors and gears. Basically the only space where you can fit stuff is underneath the cabin floor. I had to rebuild the chassis at least seven times before I could fit anything in a small enought structure, that was still reasonable stable.</p> <p><a href="http://lh3.ggpht.com/-LKbRyvdq7GU/UBP-dH97_0I/AAAAAAAACh4/HfmI1QY0Pl4/s1600-h/image3.png"><img style="background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: inline; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px" title="image" border="0" alt="image" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEifQ8-K4Nk9YkT0l8tqQbtWgCOd01TncBUalIflXhftz9TiLreUPgxosI2jyQmz4rAQOCmKKsK-PCqnsDq243dukr3Ww3_KF84ZZsscjz_69axQaXTd6sTOpwffVNo14RnaGizHYbSonrMS/?imgmax=800" width="396" height="370"></a></p> <p>The very core of the chassis.

In this particular case I needed a remote controlled lock mechanism that could handle heavy torque and also would be able to unlock the axle even if the axle is still under heavy torque. Preferably I wanted the mechanism to be controlled by a micromotor.</p> <p>Below is my solution. The dark grey gear is permanently fixed. In the picture above, with the worm gear in the rightmost position, the green axle can rotate freely. </p> <p>As soon as you turn the micromotor the worm gear moves to the left locking the green axle.</p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj_sMsfcQ8agJKY5xqRNeXLV2i-WO4cwqjy8cBBUofwamcTl-CU04w5_f2lws7QNsMeQCauJhKahJ9V5N1A4ESd81xlb7dMXt3-KrDKWhYidKwdVHlOWa2ss3x-qIdQsmIOIcbsJH7gPjo_/s1600-h/IMG_0733%25255B4%25255D.jpg"><img style="background-image: none; border-bottom: 0px; border-left: 0px; padding-left: 0px; padding-right: 0px; display: block; float: none; margin-left: auto; border-top: 0px; margin-right: auto; border-right: 0px; padding-top: 0px" title="IMG_0733" border="0" alt="IMG_0733" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTY25JHf76ptV9wPqhTKjAQXkcXVLBY6TJYUgpoCN8Bp-f3N3xnDWBFoTekBw2Y-5of0kqP3Ak7cXZ_PRSaBbMaqSLoNpzF5tzBBF9o-NJi29a2LoXRM5SCZEuiYzm1cV7vziZS1aLYz7c/?imgmax=800" width="487" height="382"></a></p> <p>Locked position.</p> JHhttp://www.blogger.com/profile/07036544908546871140noreply@blogger.com14tag:blogger.com,1999:blog-8871129855859111403.post-36815353433544857062012-05-01T17:21:00.001+02:002012-05-01T17:21:59.261+02:008109 – Flatbed Truck<p> </p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhTkBrfSUVKYutbgVCv2OFmUHJVSJw5kCA813a5L1KEDaUvknNBQv4V5mMp7HuArjlv0922fMTL9e2NmzOJf5vuW4D38C9eTowFYDFyhcr2P1rX8pk5idcKjveoV1ulcisSMy9z7Bs6tF16/s1600-h/IMG_47674.jpg"><img style="background-image: none; border-right-width: 0px; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; margin-left: auto; border-left-width: 0px; margin-right: auto; padding-top: 0px" title="IMG_4767" border="0" alt="IMG_4767" src="http://lh5.ggpht.com/-MM5PwKQk1rs/T5__bQT8jVI/AAAAAAAACPU/fiUEJTDNgK8/IMG_4767_thumb1.jpg?imgmax=800" width="388" height="533"></a></p> <p>During the first prototypes of my upcoming tractor.. </p> <a name='more'></a> <p>I regurlarly had to tow it back to the “garage” after some more or less successfull practical tests.
