Abstract
A suspension system for controlling multiple degrees of freedom of a cab of a vehicle has mounting pads that support the cab with a spring assembly connected between the chassis and each mounting pad, allowing the cab to move with multiple degrees of freedom. A lateral rod connects with one of the mounting pads, with the chassis, and restricts sideways motion of the cab. A longitudinal rod connects with one of the mounting pads, with the chassis, and restricts forward motion of the cab. A stabilizer bar connects with one of the front mounting pads, one of the rear mounting pads, the chassis structure, and controls forward pitch rate of the cab. A roll control bar connects with the rear mounting pads and the chassis structure, and controls lateral roll rate of the cab.
