Abstract
Abstract A device is disclosed for the adjusting of wheels of a motor vehicle, particularly for the adjusting of a wheel camber. The wheels, via control arms and spring struts, are heald at the vehicle body, the wheel carrier, on the one side being flexibly connected to the pivotable control arm and, on the other side being adjustably connected with the lower end of the spring strut via two fastening screws. At least one of the fastening screws is developed as part of an adjusting element, in which case a head or a nut of the element is connectable with the eccentric sleeve of a manually operable adjusting tool that can be fitted on in a formlocking way and can be detached. The eccentric sleeve can be rotated around a central axis of the screw, between two opposite supports at a lower fastening clip of the spring strut, resulting in a transverse shifting of the screw that adjusts the wheel camber.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
134 words
A wheel camber adjusting device for vehicle wheels of the type having at least two screws detachably connecting a wheel carrier with a wheel suspension support member, comprising: a support surface means adjacent a first end of one of said screws, and selectively engageable adjusting tool means, having an eccentric sleeve engageable over the first end of said screw, said eccentric sleeve being operable upon rotation thereof to forcibly change the position of the screw with respect to said support surface means to thereby adjust the wheel camber without rotational movement of the screw, the first end of said tool means including an opening for accommodating axial insertion of a screw tightening tool means, whereby the adjustment and tightening of the screw can be carried out separately from the first end of the screw.
Claim 2
Dependent Claim
134 words
A wheel camber adjusting device for vehicle wheels of the type having at least two screws detachably connecting a wheel carrier with a wheel suspension support member, comprising: a support surface means adjacent a first end of one of said screws, and selectively engageable adjusting tool means, having an eccentric sleeve engageable over the first end of said screw, said eccentric sleeve being operable upon rotation thereof to forcibly change the position of the screw with respect to said support surface means to thereby adjust the wheel camber without rotational movement of the screw, the first end of said tool means including an opening for accommodating axial insertion of a screw tightening tool means, whereby the adjustment and tightening of the screw can be carried out separately from the first end of the screw.
Claim 3
Dependent Claim
47 words
A device according to claim 1, wherein said support surface means includes opposing support surfaces of a lower fastening clip of a wheel suspension spring strut, said eccentric sleeve being formlockingly engageable over the first end of said to rotate about a central axis of said screw.
Claim 4
Dependent Claim
54 words
A device according to claim 2, wherein the eccentric sleeve has a lower cylindrical part and a connecting upper part with an external hexagon, said lower cylindrical part being formlockingly engageable over a corresponding cylindrical part of said first end of said screw, and said external hexagon being engageable by a tool handle member.
Claim 5
Dependent Claim
44 words
A device according to claim 3, wherein the lower cylindrical part of the sleeve has an eccentrically arranged cylindrical bore receiving the head of the screw and having an axis that is arranged at a distance to a central axis of the screw head.
Claim 6
Dependent Claim
38 words
A device according to claim 2, wherein the screw is guided through a bore of a wheel carrier arm and is slidably held in a transverse slot of the clip of the lower end of the spring strut.
Claim 7
Dependent Claim
24 words
A device according to claim 2, wherein a screw head of said screw has a hexagon socket for the engagement of an adjusting wrench.
Claim 8
Dependent Claim
69 words
A device according to claim 3, wherein the eccentric sleeve has an additional cylindrical bore in the upper part of the sleeve that connects to the cylindrical bore provided in the lower part, said additional cylindrical bore serving as the opening for accommodating the tightening tool means and being arranged to extend coaxially with respect to the hexagon socket of the screw head for accommodating the adjusting tool means.
Claim 9
Dependent Claim
34 words
A device according to claim 2, wherein an eccentric disk is rotatably connected with the screw that rests against opposite supports and is disposed at the end of said screw opposite the first end.
Claim 10
Dependent Claim
27 words
A device according to claim 1, wherein said first end of said one of said screws includes a socket opening for accommodating a screw tightening tool means.
Claim 11
Dependent Claim
21 words
A device according to claim 9, further comprising a screw tightening tool means in the form of a manually operable key.
