AI Technical Summary

Problems solved by technology

Although the adjustment system can adjust the camber and caster, the system also has several other disadvantages
First, the system requires relatively more time to make the required adjustments
Secondly, since the increase or decrease of the shim in one bolt will inevitably affect the camber angle of the wheel, the adjustment of the caster angle and the camber angle of the wheel cannot be independently adjusted.
Third, the system requires storage and maintenance of gaskets

Embodiment Construction

[0012] Referring now to the drawings, in which like reference numerals indicate like components in the different views, FIGS. 1 and 2 illustrate a suspension adjustment device 10 according to one embodiment of the present invention. Apparatus 10 is used to adjust the position of a suspension control arm 14 relative to frame 12 to adjust camber and caster. The device 10 is designed for use with a vehicle independent front suspension assembly. It should be understood, however, that the device 10 may be used with conventional front and rear wheel suspensions, as well as a variety of vehicles including automobiles and trucks. As described in more detail below, the device 10 may include a fastener 16, cams 18, 20, and levers for adjusting the control arm 14 relative to the frame 12 in a fore-and-aft direction (i.e., along the longitudinal axis of the fastener 16). Position means such as one or more spacers 22, 72, 74, 76, 78.

[0013] The frame 12 provides a rigid structural foun...

Abstract

A suspension adjustment device for adjusting both camber and caster of a wheel is provided. A suspension control arm is mounted between a pair of vehicle frame support members using a single fastener. Cams are disposed on either end of the fastener. The cams rotate in grooves defined in the vehicle frame support members and cause the fastener to move inboard or outboard in slots defined in the frame support members in order to adjust wheel camber. Shims are disposed about the fastener on either side of the control arm between the control arm and the frame support members. Shims are removed from one side and added to the other side to move the control arm in the fore-aft direction and adjust wheel caster Alternatively, the fore-aft position of the control arm may be adjusted by rotating a threaded bushing disposed about the fastener and extending through the control arm.

Description

technical field [0001] The present invention relates to vehicle suspension adjustment systems, and more particularly to an independent system for adjusting camber and caster. Background technique [0002] Conventional vehicle suspensions include means for adjusting the position of the suspension control arms to control wheel camber and / or caster. A conventional system for adjusting camber includes a mounting bolt extending through a suspension control arm in the fore-aft direction of the vehicle, and a pair of frame supports on either side of the control arm. The support includes elongated slots to allow movement of the bolt along a transverse axis perpendicular to the longitudinal axis of the bolt. A plurality of cams are located at either end of the mounting bolts and move within slots defined by either of the frame supports or a retaining plate secured to the supports. Rotation of the cam moves the bolt along the transverse axis and enables adjustment of the wheel cambe...
