摘要

The power unit set comprises an engine shaft (1), a differential (3) with a driving crown wheel (31) which controls the vehicle driving wheels. A gearbox (4) comprises an output shaft (2), which is rotated with a variable reduction ratio by the engine shaft, and carries a pinion (201) meshing with the crown wheel. The engine shaft, the output shaft and the rotating differential casing (30) are each rotationally guided by an upstream bearing (14,20,35) mounted on the clutch housing (10).
