ABSTRACT:
A drive system for individually driving two driven wheels of a vehicle. The system includes two continuously variable drive motors which are drivingly connected, via a transmission arrangement, with respective driven wheels. Each transmission arrangement includes a shift transmission and a bevel gear transmission, which has a fixed transmission ratio and includes a spur gearset and a bevel gearset. Shift transmissions vary the transmission ratio and the bevel gear transmission enables arranging drive shafts of the drive motors transversely to the rotational axis of the driven wheels. The spur gearsets enable vertical repositioning of the transmissions drive output shafts. Furthermore, with different arrangements of the bevel gears, inclination of respective drive motors and shift transmissions relative to the vehicles longitudinal axis and the angle of the output shafts can be adjusted, such that the drive system can be installed in different vehicle types using largely identical components.
