Multiple axle equalizing rubber suspension (ERT)

摘要

A suspension system for a vehicle includes a frame mounting bracket for mounting to the vehicle. First and second levers are pivotally mounted to the frame mounting bracket. First and second rubber torsion axle assemblies are rigidly mounted to the first and second levers, respectively. A control arm pivotally connects to the first lever and the second lever. The control arm, and the first and second levers are configured to rotate the first rubber torsion axle assembly and the second rubber torsion axle assembly simultaneously when a static or dynamic force is encountered by the suspension assembly. First and second spindle swing arms can be attached to the first and second torsion axle assemblies respectively with the first spindle swing arm extending forward of the first lever with respect to a direction the vehicle normal travels and the second swing arm can trail the second lever in a “push-pull” configuration.

主权项

1. A suspension assembly for a vehicle comprising:
a frame mounting bracket configured to be mounted to the vehicle; a first lever pivotally mounted to the frame mounting bracket; a second lever pivotally mounted to the frame mounting bracket; a first rubber torsion axle assembly rigidly mounted to the first lever; a second rubber torsion axle assembly rigidly mounted to the second lever; a control arm pivotally connected to the first lever and pivotally connected the second lever, wherein the control arm, the first lever and the second lever are configured to move the first rubber torsion axle assembly at least partially upward and to move the second rubber torsion axle assembly at least partially downward nearly simultaneously when a force is encountered by the suspension assembly.
