Abstract: A vehicle with a load space to provide a chassis comprising a framework (10) comprising a pair of spaced-apart elongate longitudinal members (12, 14) connected by a pair of spaced-apart elongate lateral members (20, 22) and bracing for the thus-defined framework, a rear suspension attached to the rearmost lateral member (20) and comprising a trailing-arm arrangement (52), and a front suspension attached to the front most lateral member (22) and comprising a leading-arm arrangement (58). This creates a rigid core for the chassis, which also provides all four suspension mounting points.

Abstract: Rubber shock absorber systems for use between the frame and equalizer bar of a construction vehicle usually fail to withstand high temperature environments. A metallic spring assembly is provided which is capable of high flexibility and durability. The spring assembly includes a first arcuate spring member and a second arcuate spring member adjacent to and inverted from the first spring member. First and second arcuate plate members are positioned against the first and second spring members respectively, and have a larger bend radius so that a clearance is created therebetween. A bolt with a plate nut threaded thereon is provided to connect the spring assembly and to provide a preload. During compressive loading, opposing end portions of the first and second spring portions are deformed to provide an energy absorbing system. The flexibility and durability of the spring assembly is controlled by the bend radius, thickness, and length of the plate members.
