Abstract
A suspension assembly for a motor vehicle including a pair of end links which interconnect the opposite ends of a stabilizer bar to a pair of suspension members. Each end link has a first fastener adapted for connection to the end of the stabilizer bar and a second fastener adapted for connection to the suspension member via locking mechanism having a pair of fastener members.
Claims19
An anti-roll system for a vehicular suspension comprising:
- a stabilizer bar having a hollow end, the hollow end having an axis and an inner surface;
- an end link having a housing and a shank extending from the housing, the shank including a threaded portion;
- and
- a locking mechanism mounted in the hollow end of the stabilizer bar, the locking mechanism having first and second locking members, each of the first and second locking members having a cooperating planar surface which is skewed to the axis of the hollow end of the stabilizer bar;
- wherein threaded engagement of the threaded portion of the shank and one of the first and second locking members generates a clamping force which when directed through the cooperating planar surfaces causes the first and second locking members to slide outwardly from the axis of the hollow end and engage the inner surface of the hollow end.
An anti-roll system for a vehicular suspension comprising:
- a tubular stabilizer bar having a bore formed therethrough;
- an end link having a housing and a shank extending from the housing, the shank including a threaded portion;
- and
- a locking mechanism mounted in the bore of the stabilizer bar, the locking mechanism having first and second locking members, the first locking member having a clearance bore and a first planar end surface, the second locking member having an internally threaded bore and a second planar surface, the threaded portion of the shank disposed through the clearance bore and threadably engaged with the internally threaded bore;
- wherein exertion of an axial clamping force produced by the threaded portion of the shank causes the first and second planar surfaces to cooperatively shift the first and second members within the bore to frictionally engage the locking mechanism with the tubular stabilizer bar.
An end link adapted for plug-in connection into the hollow end of a stabilizer bar, the end link comprising:
- a housing;
- a fastener having an externally threaded shank segment extending from the housing;
- a locking mechanism adapted to be mounted in the hollow end of the stabilizer bar, the locking mechanism having first and second locking members, the first locking member having a first planar surface which is skewed to a longitudinal axis of the first locking member, the second locking member having a second planar surface which is skewed to a longitudinal axis of the second locking member, the first and second planar surfaces adapted to slide laterally away from one another in response to an axial clamping force generated by the fastener and frictionally engage the hollow end of the stabilizer bar.
