ABSTRACT:
An automotive suspension comprises a wheel support for rotatably supporting a rear wheel, a pair of front and rear lateral link systems for supporting the wheel support on the vehicle body so that it is swingable on the vertical and longitudinal directions of the vehicle body and producing a toe-in movement in the rear wheel when the rear wheel is subjected to rearward force, and a trailing link system for supporting resiliently either one of the wheel support and the connecting portion of the lateral links with the wheel support to the vehicle body so that the wheel support is allowed to travel a short distance in the longitudinal direction of the vehicle body. At least one of said front and lateral link systems is set to exhibit a non-linear deformation characteristic with respect to lateral force acting on the rear wheel. The trailing link system is set to exhibit a non-linear deformation characteristic which has a given relation with said non-linear deformation characteristic of said lateral link system. The suspension can produce a toe-in movement in the rear wheel with respect to the rearward force so that vehicle motional stability as well as riding comfort can be improved.
