ABSTRACT:
A suspension system for suspending a final drive unit installed on an automotive vehicle. The final drive unit including a drive shaft drivingly coupled to a cardan shaft, and output shaft drivingly coupled to road wheels for transmitting a drive from the cardan shaft to the road wheels. The drive shaft has an axis extending longitudinally of the vehicle. The output shafts have an axis extending transversely of the vehicle. The final drive unit is subject to reaction torques causing the final drive unit to make a rolling angular displacement around the drive shaft axis and reaction torques causing the final drive unit to make a pitching angular displacement around the output shaft axis during vehicle driving. The suspension system includes elastic suspension elements for elastically flexibly suspending the final drive unit, with respect to the vehicle, at suspension points located at different positions to reduce the pitching angular displacement substantially to zero.
