Yuri writes about these differences on the forum of the site under the nickname tandem.
Great view of a crawler all-terrain vehicle.
Video about all-terrain vehicle "Tandem Truck".
The performance characteristics:
75 hp engine petrol.
5-speed manual gearbox.
Permanent blocking of two sides during rectilinear traffic.
Turn control steering.
The inner turning radius is zero.
Independent suspension on the levers of the balancers.
The drive axle consists of three main gears. In the middle final drive, the differential is brewed. Constant blocking during rectilinear movement is achieved by constant braking of the shank of the two extreme main gears. Gearboxes taken from Mercedes S500w300 gear ratio 2.82. The back cover of the gearbox has cooling fins. The slots on the half shafts are long. For braking, a four-piston caliper BREMBO was applied to each shank. Larger diameter ventilated brake discs. A universal joint shaft is connected to the engine through a manual gearbox and clutch.
One gearbox weighs 35 kg. 35x3 = 105 kg.
Brake disks together with calipers 2x14 = 28 kg.
Total 133 kg for the whole mechanism.
The gearbox is filled with this kind of oil.
Exactly the same calipers are installed on the hubs of the leading sprockets.
The tracks are made. Caterpillar tracks are connected by links that are made of a profile pipe 50 × 25 × 2 mm with a length of 125 mm. The ends are welded. Camposide material is pressed inside, consisting of three natural materials, thermally processed.
The caterpillar is collected on a conveyor belt.
Turn the caterpillar in place.
Mileage tracked all-terrain vehicle at the moment is not very large, so there may be no breakdowns and gusts of tracks.
We wish Yuri success in all-terrain engineering.
