ABSTRACT:
A coil spring suspension system that differs from conventional prior art coil spring suspensions in that an additional A-arm is used, the additional A-arm being vertically oriented and having its leg ends attached to the leg ends of the horizontally oriented upper A-arm. The vertically oriented A-arm has its leg ends pivotally attached to the vehicle frame or body with the leg ends of the upper horizontally oriented A-arm. The apex of the vertically oriented A-arm lies in or near the plane of the lower horizontally oriented A-arm. A coil spring is used, having a substantially horizontally oriented longitudinal axis, with one end of the coil spring secured to the horizontally oriented lower A-arm near the apex of the horizontally oriented lower A-arm and with the other end of the coil spring attached to or near to the apex of the vertically oriented A-arm.
