Abstract
An independently sprung front suspension system for improving the ride and handling of a recreational vehicle having a unitized body and frame. A wishbone-shaped lower control arm having spaced apart inner ends is mounted for pivotal movement on a control arm shaft, and a tubular member surrounding the control arm shaft is secured to the frame. A pair of spaced apart elastomeric bushings are mounted on the shaft within the tubular member which permit large horizontal deflection and minimal vertical deflection of the shaft within the tubular member during road impact and braking conditions, thereby substantially isolating the frame from such road impact. The elastomeric bushings also have their respective outermost ends contoured to prevent excessive wear thereon during such horizontal movement, and end stop washers are placed between the ends of the tubular member and the adjacent control arm ends for limiting axial and horizontal movement of the shaft and the elastomeric bushings within the tubular member and to assist in the prevention of excessive wear of the elastomeric bushings.
