Suspension system with transverse leaf spring

摘要

A suspension system on a motor vehicle includes a transverse leaf spring interconnecting knuckles on which road wheels are rotatably supported. The suspension system includes a pair of knuckle members on which the road wheels are rotatably mounted, an elongate leaf spring which is vertically resilient and extends transversely with respect to the vehicle body, the leaf spring having opposite ends coupled to the knuckle members, respectively, a support member supporting the leaf spring at two supporting points thereon which are spaced from each other transversely with respect to the vehicle body, for allowing the leaf spring to move transversely but limiting the leaf spring against vertical movement with respect to the vehicle body, and a transverse movement limiting mechanism for allowing the leaf spring to move vertically but limiting the leaf spring against transverse movement with respect to the vehicle body. The transverse movement limiting mechanism comprises a link mechanism which couples a portion of the leaf spring between the two supporting points to the vehicle body.
