Torsion spring rod system for wheel suspension of two-lane motor vehicle, has torsion spring rod that comprises two rod portions and intermediate spiral or helical spring element, which are arranged between actuator and driven lever

摘要

The system comprises an actuator (31) that is arranged on a vehicle chassis (20) and is connected to an output lever (38) through a torsion spring rod (22). The biasing force of the output lever acts on a wheel suspension element (12) of a wheel suspension. The torsion spring rod comprising two rod portions (23,25) and an intermediate spiral or helical spring element (26), which are arranged between the actuator and the output lever. The spring element in which the rod portions are rotatably mounted, is supported between two bearing points (35,39).
