  • Vehicle suspension system
    Patent number: 5016903
    Abstract: A vehicle suspension system includes an arm member whose outer end is connected to a wheel and whose inner end is connected to the vehicle body by way of front and rear rubber bushings at positions spaced from each other in the longitudinal direction of the vehicle body so that the arm member can vertically rotate relative to the vehicle body. Each of the front and rear rubber bushings has an outer tubular member which is substantially cylindrical and extends in the longitudinal direction of the vehicle body, an inner tubular member which is received in the outer tubular member substantially coaxially therewith, and a rubber member interposed between the inner and outer tubular member. One of the inner and outer tubular members is connected to the vehicle body and the other is connected to the suspension arm.
