Patent ID: 7722062

Claim:
A suspension system for a motor vehicle that controls torque reaction comprising: a chassis; a rigid drive axle; an opposite axle; two rotatable axle attachment structures; at least one fixed lower axle attachment structure; a road wheel attached to each end of each axle; at least two longitudinal control arms attached to said two rotatable axle attachment structures at said rigid drive axle proximate said road wheels, for longitudinal control of said rigid drive axle; at least one torque reaction control link positioned longitudinally of said motor vehicle between said road wheels attached to said at least one fixed lower axle attachment structure for controlling torque reaction of said rigid drive axle in combination with said at least two longitudinal control arms; wherein one end of each said at least two longitudinal control arms are pivotally connected to said rotatable axle attachment structures proximate said road wheels and the other end of each said at least two longitudinal control arms are pivotally connected to said chassis, so that each said at least two longitudinal control arms has an effective projection line longitudinal of said motor vehicle; wherein one end of said at least one torque reaction link is pivotally connected to said at least one fixed lower axle attachment structure for said rigid drive axle and other end to said chassis, so that said at least one torque reaction control link has a longitudinal plane that extends longitudinally of said motor vehicle and whereby said effective projection lines of said at least two longitudinal control arms and said longitudinal plane of said at least one torque reaction control link intersect each other in the direction of said opposite axle, forming a convergent angle and that when a force moves said rigid drive axle vertically up said convergent angle does not increase.
