Automobile steering wheel return mechanism comprises cam integral with wheel which engages support subjected to spring action exerting return couple on wheel and to damper exerting opposing couple

摘要

The return mechanism (15) for a steering wheel (10) comprises a cam (26) integral with the wheel which engages a support element (53). The support element is subjected to the action of a spring (46) which exerts a return couple on the wheel increasing over the initial range of the wheel displacement from a reference position. The support is also subjected to a damper (56) which exerts a couple opposing the displacement variation on the wheel.
