Propulsion system for motor car, has high rigidity spring element that provides torsional degree to reduce torque fluctuations in rotary movement

摘要

The propulsion system (20) has an axle gear box (21) that is operatively coupled with a drive shaft (23) and a driven shaft (24a) for transmitting a rotational movement. A high rigidity spring element (25) provides a torsional degree to reduce torque fluctuations in the rotary movement. The torsional rigidity of the spring element is set less than the torsional rigidity of the driven shaft.
