US 2017/0282664 A1 · SPRING AID ASSEMBLY FOR A VEHICLE SUSPENSION SYSTEM

Abstract

A spring aid assembly for a vehicle suspension system. The spring aid assembly includes: a housing having a generally cylindrical cavity formed therein, a damper including a rod extending through a cap, and a spring aid having a proximal end retained within the cavity of the housing, a distal end extending in an axial direction away from the housing, and an outer circumferential groove formed therein. The cavity in the housing is bounded by a generally cylindrical inner peripheral wall that has a plurality of axially and radially extending projections extending therefrom. A ring is positioned in the outer circumferential groove of the spring aid. The ring provides a positive stop to the spring aid assembly and prevents the cap of the damper from coming into direct contact with the housing during full compression of the damper.

Dependent claims

A spring aid assembly for a vehicle suspension system having a top mount and a damper, the spring aid assembly comprising:

a spring aid having a proximal end, a distal end, a central passageway extending from the
proximal end to the distal end to receive a rod of the damper, and a circumferential groove in an outer surface of the spring aid,
the proximal end being configured to fit in a cavity of the top mount, the proximal end including a plurality of recesses that mate with provided in the cavity;
and
a ring positioned in the circumferential groove of the spring aid,
wherein the ring indirectly rests on one or more of the projections when the spring aid assembly is fully compressed such that said ring provides a travel stop to the vehicle suspension system that prevents a cap of the damper from coming into direct contact with the top mount during compression of the rod damper.

A vehicle suspension system, comprising:

a top mount having an axial bore extending therethrough along a central axis and a generally cylindrical cavity formed in a bottom portion thereof, the cavity in the bottom portion of the top mount being bounded by an inner peripheral wall that has a plurality of axially and radially extending projections extending inwardly therefrom;
a spring aid having a proximal end retained within the cavity of the top mount, a distal end extending in an axial direction away from the top mount, a central passageway extending from the proximal end to the distal end, and a circumferential groove in an outer surface of the spring aid;
a ring positioned in the circumferential groove of the spring aid;
and
a damper including a housing and a rod extending out of the housing through a cap at one end of the housing, the rod of the damper extending through the passageway of the spring aid and being received in the bottom portion of the top mount and extending at least part way through the axial bore of the top mount;
wherein the ring indirectly rests on one or more of the projections when the spring aid assembly is fully compressed such that the ring provides a travel stop to the vehicle suspension system that prevents the cap from coming into direct contact with the top mount during compression of the damper.
