Abstract

The invention relates to a prestressed rubber suspension/shock absorber system for vehicle axles in general. The inventive system comprises two concentric tubes; one inner and one outer tube. A power lever is welded to, or forms an integral part of, the outer tube and is used to articulate said tube to the axle, spring or spring mount of the vehicle by means of a bushing or perforated support plates. Two steel support plates, comprising a perforation at the ends thereof, are welded to the ends of the inner tube or axle, each of said plates being used to articulate the inner tube to the axle, spring or spring mount of the vehicle. A mixture of natural and synthetic rubber is disposed between the two tubes, said mixture being affixed to the contact surfaces thereof. When the tubes are rotated one inside the other, said surfaces subject the rubber to tension. The inventive system is characterised in that it is prestressed in the factory with the force and position required for use in the majority of vehicles having their original body. Said system can be used together with standard factory-installed suspension systems or as an integral suspension system. Moreover, the invention can be used: (i) diagonally, as a shock absorber between the axle and the chassis; and (ii), vertically, as an auxiliary suspension between the axle and the chassis.
