Abstract
Abstract An independent suspension mechanism for automotive vehicles having a pair of suspension arms which are pivotally connected with the structural members of the vehicle body by means of specially constructed support member. The support member may include a rigid or, preferably, resilient bushing providing a sufficient amount of prestress in the axial and radial directions of the pivot shaft of the suspension arm. The support member may be connected to the structural member or members through a brace which is substantially resilient in the direction of the pivot shaft.
