Suspension system for dirigible rear wheels

摘要

A rear suspension system for supporting dirigible rear wheels of a vehicle consists of left and right rear suspensions each of which includes first and second links which are connected for rotation to the rear wheel support in different positions at their outer ends and to the vehicle body in different positions at their inner ends and a damper which is connected to the vehicle body at its upper end and to the first links at its lower end. The dampers of the left and right rear suspensions are inclined to the corresponding first links so that they transmits force to the first links to generate moments about instantaneous centers of turn of the respective rear wheel supports. The moments are substantially equal to each other and are directed in opposite directions when the rear wheels are held in the straight ahead position. The first and second links are arranged so that the sum of the moments becomes positive as the rear wheels are turned when a moment in the direction of turn of the rear wheels is defined to be positive and a moment in the reverse direction is defined to be negative.
