ABSTRACT:
A vehicle rear suspension mechanism capable of producing a toe-in displacement under a side force, a brake force, an engine brake force and an engine drive force to obtain a stabilized steering property. The mechanism includes a suspension member connected with a vehicle body, a wheel hub supporting a rear wheel for rotation about a rotating axis, a connecting device for connecting the wheel hub with the suspension member. The connecting device includes a ball joint connecting the wheel hub to the suspension member pivotably about the joint center. The ball joint is located in one of four quadrants defined in a rectangular coordinate system having its origin on the rotatable axis of the rear wheel. The device also includes a first resilient bushing located between the wheel hub and the suspension member in one of the three remaining unoccupied quadrants and a second resilient bushing located between the wheel hub and the suspension member in one of the two remaining unoccupied quadrants. In certain embodiments, the first and second bushings are of unequal relative rigidity. In still other embodiments, each of the first and second bushings include stoppers to restrict either forward or rearward movement of the wheel hub.
