Many builders think, 8880's drive is weak. With blue, I marked the moving parts in steering (except the white hubs):Īs you can see, there are minimal torque in the 12 t bevel gear, and maximal in the 40t gear's axle. Here you can see the front axle, in LDD an IRL:
I make this moc first of all in LDD, and I'M trying out the important working parts. The roof will be partly openable, to switch the RC unit on-off, and for changing the batteries. But, of course, there will be large gearing just before the wheels, so, yes, a torque reducing gearbox will be there, but with normal gearing (spur-gears, bevel gears).Īnd, of course because of RC there will be no fake engine, it's a compromise, we know well.īut, I'll make the cabin, at least the driver's seat, working steering wheel, openable doors. My goal isn't to make it authentically working, but to build it reliable, robust, and proportional. I just want to say with this, the space is very limited. This model has to contain the big RC unit, two RC buggy motors, 1 LiPo battery, 1 Receiver, at least two M motors, all of these in the front part, above the 4 front wheels. The harder part is the drive system, to be enough strong and to fit in the relatively small place (the truck will be only 24 studs wide, and has huge wheels). Everywhere will be A arms, and in the front I'll put the yellow shocks, with place for additional ones, if needed, and in the rear I'll make simply the bogies to get the wheels linked. That big beam is a bit flexible I think, works a little as spring in the back. The rear wheels are linked together, in each side. and shock absorbers for all front wheels. In the front, there are torsion bars, as can be seen in this model: You know well, it has simple A-arms / double wishbone system in front and rear. The Maz 537 also has - besides the standard gearbox - portal gearboxes to reduce torque in most of the drive train. I'm very curious how you are going to realize this. are appreciated, as always.Īs far as I know all axles are double wishbone with shocks in the front axles and rigid bogies (no shocks) in the rear. If a 30° slope and a terrain with 3-4 studs high obstacles is no problem, then I reached my goal with it's off-road capabilities.Ĭomments and questions, ideas, etc. It's a heavy truck (will be about 3 kg), so even with robust drivetrain I think it won't be capable of doing trial/heavy terrain, but if a medium can be done, that's far enough for me. The shifting to second gear this way will be an additional extra, if you want to do. By default, the gearbox will be in first gear, when the servo is in 0 position, so it will be reliable under torque. To help in this process, and fix the slifing axle in the second gear's position there will be magnets somewhere. The gearbox would be a sliding type, and it's movement will be done by the servo of RC unit. Fortunately, there are curved dark green bricks, to make the curved edges in the top and front. I collected a pretty large amount of dark green bircks, tiles, etc., so the color shouldn't be a problem. There will be pictures about the process soon, first I make the front axles and the main placing of components, steering. working towing cable, with heavy winch and hook (metal) 2 speed gearbox controlled by the RC unit's servo
#Spintires position your truck properly full#
full authentic (independent in front and semi-independent in rear) suspension with minimum 2-3 studs of suspension travel proportional looking, with model body and details, as close to the original as possible Radio controlled with RC buggy system, 1 RC unit, 2 RC motors Thanks to spintires, we have some good looking high quality render, so I can make the details properly: I'll make the tractor truck, so there will be no cargo platform in the back.
Of course, in this size I'll use again the crawler tyres, RC4WD rock crusher XT's, and maybe later I'll buy a more authentic looking military tyres. I build in 1:15 scale, which means the 108 mm tyres. It's an awesome and indestructible machine, a real russian cold war truck.
I know about this heavy truck before spintires, too, but when the tech demo released, I could finally "drive" it, simulating a bit the behavior of this truck. I build the monstrous Maz 535, inspired mainly by real life Maz (537, because there are no working 535 any more, if I know well), and a bit of Spintires. I present my newest project, which is among my biggest ones ever. LEGO Digital Designer and other digital tools
