Patent ID: 7588260

Claim:
A suspension system for a vehicle comprising: a beam axle extending laterally; an upper control arm disposed above said beam axle for operative connection to vehicle structure of the vehicle and said beam axle; a lower control arm extending longitudinally having a forward end and a rearward end forming a triangular shape, said lower control arm being spaced vertically below and laterally outward in relation to a centerline of the vehicle from said upper control arm for operative connection to the vehicle structure and said beam axle; a plurality of first bushings connected to said rearward end of said lower control arm, said plurality of first bushings comprising a pair of mutually spaced apart first bushings, said plurality of first bushings being disposed below said beam axle for operative connection to said beam axle; and a second bushing connected to said forward end of said lower control arm for connection to the vehicle structure of the vehicle; wherein said triangular shape of said lower control arm provides a generally triangular disposition of said pair of first bushings and said second bushing, wherein said plurality of first bushings, said second bushing and said triangular shape of said lower control arm cooperatively provide lateral stiffness of the lower control arm which is a function of axial, conical and radial stiffness of said plurality of first bushings and said second bushing, and further provide deflection modes of said beam axle which are independently alterable.
