Abstract
A vehicle rear suspension system having a vertically swingable arm connected at the front end swingably to the vehicle body and secured at the rear end to a wheel carrying member which carries a rear wheel for rotation. Three lateral links ar provided and have inward ends pivotably connected to the vehicle body and outward ends pivotably connected to the wheel carrying member. The points of connection of the three lateral links to the wheel carrying member are not aligned in a straight line so that the orientation of the wheel carrying member can appropriately be controlled under bump and rebouncing movements of the rear wheel and under side and longitudinal forces acting on the rear wheel.
Claims29
In a vehicle rear suspension system for a rear wheel of a vehicle including a wheel carrier having a rotational axis for a wheel, a swing arm pivoted at one end to the vehicle through a resilient bushing, and lateral links each connected at an inward end to the vehicle and at an outward end to the wheel carrier, the improvement comprising a toe angle control means for controlling the toe angle of the wheel, said toe angle control means comprised of a pair of the lateral links horizontally spaced apart, a camber angle control means for controlling the camber angle of the wheel, said camber angle control means comprised of one of the pair of lateral links comprising the toe angle control means and a third lateral link, single pivot means for pivotally connecting one end of said third lateral link to the vehicle and the other end of the third lateral link located above the pair of lateral links, said first, second and third lateral links being connected to the wheel carrier at points displaced from the rotational axis, and connection means for connecting the other end of the swing arm to the wheel carrier providing one of a pivotal connection about a vertical axis and a connection allowing lateral relative displacement, said connection means preventing relative rotation between the other end of the swing arm and the wheel carrier about a horizontal axis.
