VEHICLE CHASSIS AND SUSPENSION SYSTEM

摘要

A haulage vehicle has a suspension system providing a flexible connection between a vehicle chassis and at least one axle housing. The system has three longitudinal link members, a transverse link member, and a resilient member adjacent each end of the axle housing; all of which are connected at one end to the vehicle chassis and at an opposite end to the axle housing. The transverse link member substantially prevents movement of the axle housing in a transverse direction, and the three longitudinal link members are substantially aligned with the longitudinal axis of the chassis and spaced apart, providing a three-point connection between the chassis and axle housing. The three-point connection keeps the axle housing in a substantially transverse orientation relative to the chassis, preventing rotation of the axle housing about the longitudinal axis of the axle housing while allowing movement of the axle housing in the vertical plane.

1. A vehicle suspension system for providing a flexible connection between a vehicle chassis and at least one axle housing, the vehicle suspension system having three longitudinal link members, at least one transverse link member, and at least one resilient member situated adjacent each end of the axle housing; all of which are connected at one end to the vehicle chassis and at an opposite end to the axle housing, wherein the at least one transverse link member is configured to substantially prevent movement of the axle housing in a transverse direction, and the three longitudinal link members are each substantially aligned with the longitudinal axis of the chassis and are spaced apart to provide a three point connection between the chassis and the axle housing which is configured to keep the axle housing in a substantially transverse orientation relative to the chassis and to prevent rotation of the axle housing about the longitudinal axis of the axle housing while allowing movement of the axle housing in the vertical plane, and wherein movement of the axle housing in the vertical plane is limited by the resilient members which connect each end of the axle to the chassis.
