Abstract: A modular anti-sway bar assembly for heavy duty vehicles. The anti-sway bar has multiple components including a main torsion bar which is equipped at each end with a splined connecting surface. The splined ends of the main torsion bar allow it to be easily disconnected and removed from the vehicle. Each of the splined ends of the main torsion bar is gripped by an arm, which is generally horizontally oriented and which is connected by a vertical link to a wheel end. The main torsion bar is guided along its length and restrained from axial motion by a pair of support bushings, each of which is held in a pocket in a suspension side plate. The main torsion bar passes through openings in the side plates.

Abstract: An integrated assembly for large vehicles including independent suspension components, supporting side plates and axle and frame components. Each of the side plates is a weldment in which the main part is a series of metal plates formed by bending a single sheet. Pockets are formed on the outside surfaces of the side plates. The pockets support the upper ends of suspension components, i.e., a coil spring, a shock absorber and a jounce bumper, while the lower ends of the suspension components are carried by a lower control arm. The half-shafts of each axle, extend through the side plates which are carried by two C-shaped main frame members.
