[MOC] Patria AMV (Nemo Version)
Doc_Brown posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Season greetings! I thought I would finish this year with a bang! So I am very very pleased to present my Technic version of the Patria AMV (Nemo Version) This is the biggest, baddest MOC I have ever made, and probably will be for a long time! I have been building this MOC on off from the start of the year, so I am very glad that it is finished! Its functions are: 4x XL Motors for propulsion 1x Servo for steering 3x M Motors for Turret and Rear Door 3x PF Lights Full Independent suspension 8x Ansmanns 1.9” Tires “Twin” 2 Speed Differential Gearbox Specs: 71cm (L) x 21cm (W) x 27cm (H) 5.6KG Weight Hope you enjoy the video! Took me 5 days of recording and editing to make, so please take a moment to log in and Subscribe, rate and comment! Thanks! Nice pics are coming soon, and dismantle video as well. Happy New Year! -
8x8 Trial Truck Chassis
1nxtmonster posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi guys. I'm back with my latest ongoing build, an 8x8. Each axle has it's own ball-joint suspension, so the ground clearance and articulation are both very good. Independent steering on the two front axles using two M motors. Two XL motors for drive with a final ratio of 3:25. Overall a very sturdy and well-performing truck. -
Zis e134 - 8x8 - RC
Tamas Juhasz posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! This moc was made a while ago (last year), but I realized, there is no topic about it yet. I wanted to make a heavy and fast trial truck from Zis e134. Original model: My version: folder: http://www.brickshel...ry.cgi?f=496827 Basically, it was built for truck trial race, so it has a "propulsion motor/weight" ratio, each RC buggy motor carries ~ 1 kg. There are 4 buggy motor built in, each axle has one. Only two gearings (40:8 and after that a 24:8 reduction) are in the drivetrain in each axle, so I hadn't problems with efficiency. Total wieght became 4190 g. I used 1957 parts to build it. It's my longest and heaviest trial truck yet, total length is 610 mm (width: 283 mm). The 4 motors give enough power to reach 1,7 km/h top speed (flat surface), I used two RC units to power them. I think the most important part in these 8x8 trucks is the suspension. I tried to make a long travel one, which allows the wheels to make contact with the ground in extreme terrain also. The rear axles are built in a unit, which has a linkage (see pictures). This unit can bend also, but not sideways. The two front axles can bend sideways, and lenghtwise also. So without springs, the suspension does it's job: The second and third axle are connected together with these bars. They seems weak to here, but I can say, there weren't problems with those during the tests and races. They don't hold the axles, only make positioning, but of course, some force can be appear: Bottom: I made some details, like net in the driver's door, flags, grilles to the front: This truck was able to drive in heavy snow.

Mini RC Tatra 813 - 8x8
Tamas Juhasz posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! My newest mini moc is also a Tatra. My goal was to make a 8x8 813 model with realistic Tatra suspension: This was my first moc, which could be build with 1:1 scale from a paper: I always wanted to build a really small Tatra with the wheels from 8842. This wheel has a diameter of 43 mm, so the proportional width is about 11 stud. That's even not enough, too narrow, but I had success with the suspension and drivetrain in 13 stud width. The first and second axle has steering, and all axle is driven and suspended. With U-joint there is no way to build it narrower. I used 3 different shock absorbers. The first axle has harder ones to hold the weight reliable in the front. The steering mechanism only steers directly the left wheels, the right ones are steered by the 9L links: http://www.brickshel...y.cgi?i=5748589 The ground clearance enables 25 mm high obstacles under the truck. Of course it can go through much bigger ones, as can be seen below in the video. The drivetrain is pretty simple Tatra like, with assimmetric left and right side: http://www.brickshel...y.cgi?i=5748587 In the picture it also can be seen that the front 4 wheels are driven with a small 2L thin liftarm to prevent clacking(if it uses pins and pulley). There wasn't problem with that, in every terrain kept the front wheels the correct position. They look like the valve cover of the wheels.( I forgot to take them also in the rear wheels) Maybe from the pictures we can think that the 12 bevel gears can go out in the middle of the axles. They can't. The 2L red axles prevent that (I used strong 12 gears and loose U-joints). The suspension worked well in terrain, this Tatra doesn't carries tons of weight, stronger axles aren't necessary. The wheel travel is about 2 stud or a bit more depending of the axle. Technic inside: http://www.brickshel...y.cgi?i=5748652 The steering M motor is in the front, the driving M motor is in the rear part. The M motor is powerful with 6:1 final ratio. It can be, because the weight is only 761 g. The stability surprised me. In the video can be seen some test. The aesthetics was also important for me, this one isn't a trial truck, more civil version. I had to cut the mudguards to give space for the wheels, and of course it's a bit higher than the real Tatra to have wheel travel. The front grill has a Tatra logo and some covering sticker: The on/off button is in the top of thew vehicle: If you hit the PF connector, the front LED lights will work(video). I didn't want a PF switch, and wanted to try this out. And the video with infos: If somebody needs, I can upload the building instructions. -

Did someone try 2 L motor on an axle instead of a differential?
midengineaddict posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
In my next 8x8 crawler project I have the intention of trying a setup with the two rear axle with 2 L motor each (a motor for each wheel). the two front axles only will steer with a servo, an L motor and a differential on each axle... and all axles will be floating with 4 links and horizontal chock absorber. Did someone know if its a goon idea or if a topic already talk about this setup? -

8x8 Trial Truck, The Pumpkinator!
Saberwing40k posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Well, here we are. This is my latest truck, and I call it, due to the color, the Pumpkinator. All eight wheels are driven, and the front four steer. Drive is via one XL motor, geared down roughly nine to one. The axles are loosley inspired by a design from Zblj, and are very tough, except for the third axle, which has grinding gears. Suspension travel is not a whole lot, but it does the job, and is fairly compact. This truck is actually a project I was making for school, and was originally going to be an Oshkosh PLS truck, although this did not pan out due to time constraints. I built this thing in only 6 hours! Anyway, I got a good grade, which was a good thing . I may or may not make instructions, and a video. Would anybody want either of those? Anyway, on to the pictures, and some additional details. The side views, showing the roll cage (made out of 32l axles), the suboptimal location of the battery boxes, and the spare tires. The underside view, showing the drive axles, the drive motor, and the suspension setup, which is 4 link. A closeup of the rear 2 axles, showing the mechanics. The connection to the third axle is rather weak, and the gearing skips. However, it only does this on extreme slopes. The front axles. This was the hardest part to make. The steering motor. The cabin has no interior, as it was literally an eleventh hour addition. The connection from the front motor to the steering axle. The steering clutch sometimes balks, so that's goin to be redesigned. The top of the suspension, which is mostly identical for all axles. Front view with the lights on. Rear view with the lights on. The very front, but it's not actually based on any Mercedes... Suspension travel. Upper limits. Enjoy, and keep on building!
