Shear spring useful for vehicle suspension

摘要

A shear spring having a base plate having a flat upper surface, and an upper plate having a V-shaped upper surface opposite the base plate adapted to mate with a corresponding V-shaped surface positioned on a side wall of a spring mount, the upper plate having a flat lower surface parallel to the flat upper surface of the base, and an elastomeric material positioned between the flat upper surface of the base plate and the flat lower surface of the upper plate.

主权项

1. A suspension for supporting a longitudinally extending vehicle frame rail above an axle, comprising:
a first frame attachment portion adapted for connection to the vehicle frame rail; a first spring module attached to the first frame attachment portion; said first spring module having an opening; a first spring mount positioned within the opening of the first spring module; a first shear spring positioned between a first side wall of the first spring mount and a first side wall of the opening of the first spring module; a second shear spring positioned between a second side wall of the first spring mount and a second side wall of the opening of the first spring module; said first spring mount comprising an inboard part and an outboard part separate from the inboard part, a first through-hole positioned in at least one of the inboard or the outboard parts of the first spring mount adapted to allow passage of a first connecting rod therethrough, wherein the first connecting rod connects the inboard part of the first spring mount together with the outboard part of the first spring mount, and wherein the first shear spring has a V-shaped outer surface, where the first shear spring is compressed between the first side wall of the first spring mount and the first side wall of the opening of the first spring module, and wherein the second shear spring has a V-shaped outer surface, where the second shear spring is compressed between the second side wall of the first spring mount and the second side wall of the opening of the first spring module.
