Driveline and rear axle

Design and specifications

Driveline consists of two tubular shafts fixed to a base body intermediate support mounted on ball bearings. The front and rear end of each shaft are flexible couplings with centering bushings. The shafts are interconnected by a crosspiece hinge.

Rear Axle

Sprung rear axle with hypoid final drive. Drive pinion rotates in the tapered roller bearings. The rear axle is fixed to the rear part of the base body. Driving the rear wheels pivot shafts made. Pinion rear axle is installed on two tapered roller bearings. Differential performed on two planetary gears mounted on the same shaft.

Characteristic	Value
Used oil
ordinary bridge	Hypoid oil SAE 90; 85W90
bridge with a controlled slip differential	Hypoid oil SAE 90
Fuel capacity of housing, l	0.7-1.3 *
Replacement interval	after the first 10,000 kilometers
The frequency of checking the oil level	every 16,000 kilometers

* Depending on the engine.

Rear wheel drive

Each wheel consists of two ball constant velocity joints because angular displacements are small universal joints, wear minimal.
