Abstract
A rear wheel suspension system for a four-wheeled vehicle suitable for attaining vehicle weight reduction, setting weight distribution of the vehicle, improving vehicle design freedom, and decreasing the number of components as compared to conventional rear wheel suspension systems. The system includes a joint member mounted in a rear portion of a vehicle body with a pair of left and right front wheels secured thereto, the joint member including a roll shaft extending substantially in the longitudinal direction of the vehicle body, and connecting to a vertical swing shaft extending in the transverse direction of the vehicle body. In addition, a power unit for supporting the two rear wheels is connected to a rear portion of the joint member by means of the vertical swing shaft, thereby allowing the power unit to be secured to the vehicle body rollably and swingably.
