Abstract
A suspension (10) for multi-wheeled vehicles includes a pair of outer equalizing beams (18) rockably supported by trunnion assemblies (22, 26) for deflection in response to changes in the terrain over which the vehicle travels. The equalizing beams (18) mount a pair of axles (16) supporting ground-engaging wheels. At least one inner equalizing beam (20) is mounted to a trunnion assembly (24) with the inner equalizing beam (20) providing a support for mounting of two leaf spring assemblies (28, 30) between the outer equalizing beams (18). In one embodiment, a four-axle suspension includes two leaf spring assemblies (28, 30) on each side of the vehicle. Each leaf spring assembly (28, 30) is secured between one of the outer equalizing beams (18) and the inner equalizing beam (20). The leaf spring assemblies (28, 30) include an axle connection (34) for supporting an axle (14) and a ground-engaging wheel. Load equalization is enhanced by radius rods (80, 100) which extend between one of the axles (14) and one of the trunnion tubes (46). The radius rods (80, 100) also tend to limit deflection between axles. In another embodiment, a five-axle suspension in accordance with the invention in…
