International Classification:

B60G 5/00

US Classification:

280681, 28012411, 280124178

Abstract:

An elastomeric spring suspension is described for supporting a longitudinally extending vehicle frame rail above first and second axles forming a tandem axle configuration. The suspension includes a frame hanger assembly mounted to the vehicle frame rail. The frame hanger assembly has two full spring modules, each of which includes two shear springs, a progressive spring rate load cushion having a pyramidal shape with a flattened top surface and a spring mount for mounting the springs. A saddle assembly is connected to the spring mount, and an equalizing beam is connected to the saddle assembly and further connected to the axles. The spring rate for the suspension increases almost linearly as a function of sprung load, resembling a pneumatic suspension. Accordingly, the suspension exhibits excellent ride quality, without sacrificing roll stability.

US Classification:

280124116, 2671411, 280681, 280124178

Abstract:

A vehicle suspension including a frame attachment portion attached to spring module having an opening defined by two side walls, a top wall and a bottom wall, and a spring mount positioned within the opening with two shear springs on either side of the spring mount, wherein the spring mount includes an inboard part and an outboard part separate from the inboard part, and a through-hole positioned in at least one of the inboard or inboard parts to allow passage of a threaded connecting rod therethrough, wherein the connecting rod has been tightened to draw the inboard part of the first spring mount together with the outboard part of the first spring mount, and to compress the first shear spring between the first side wall of the spring mount and the first side wall of the opening, and also to compress the second shear spring between the second side wall of the spring mount and the second side wall of the opening of the spring module.

US Classification:

280681, 267292, 280687, 280124116, 280124177

Abstract:

A shear spring comprising a base and a V-shaped surface opposite the base adapted to mate with a corresponding V-shaped surface positioned on a side wall of a spring mount, and an elastomeric material positioned between the base and the V-shaped surface, wherein the base includes a first flange extending away from the V-shaped surface and adapted to be positioned outwardly from a first edge of a side wall of a spring module, and wherein the base includes a second flange extending away from the V-shaped surface and adapted to be positioned outwardly from a second edge of the side wall of the spring module, where the first flange and the second flange are positioned in parallel planes.
