Abstract
Abstract A wheel suspension for motor vehicles which includes a wheel guide member retained at the body or at the frame of the vehicle and a wheel carrier pivotally connected to the wheel guide member by the interposition of elastic elements; the elastic elements between the wheel guide member and the wheel carrier are thereby so arranged and/or constructed that the wheel steering-pole of the elastic wheel movement-as viewed in plan view-assumes a position in which the wheel is substantially non-adjustable or is adjustable only in the direction of a toe-in under the influence of forces acting on the wheel.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
105 words
A wheel suspension for a vehicle comprising: wheel guide means retained at a relatively fixed one of a vehicle body having a longitudinal direction and a vehicle frame, wheel carrier means for rotatably supporting a vehicle wheel in use, plural elastic support means interconnecting said wheel carrier means and said wheel guide means, at least two of said elastic support means being, respectively, of different elasticities and arranged in such a manner as to yield a wheel steering moment pole of elastic wheel movement which is located so as to permit only toe-in wheel adjustment in response to forces acting on the wheel in use.
Claim 2
Dependent Claim
105 words
A wheel suspension for a vehicle comprising: wheel guide means retained at a relatively fixed one of a vehicle body having a longitudinal direction and a vehicle frame, wheel carrier means for rotatably supporting a vehicle wheel in use, plural elastic support means interconnecting said wheel carrier means and said wheel guide means, at least two of said elastic support means being, respectively, of different elasticities and arranged in such a manner as to yield a wheel steering moment pole of elastic wheel movement which is located so as to permit only toe-in wheel adjustment in response to forces acting on the wheel in use.
Claim 3
Dependent Claim
47 words
A wheel suspension according to claim 1, wherein the wheel steering moment pole is located outside the wheel track in use and to the rear of a vertical plane extending through the center of the wheel in use and substantially parallel to the vehicle body longitudinal direction.
Claim 4
Dependent Claim
94 words
A wheel suspension according to claim 1, wherein the elastic support means connecting the wheel carrier means with the wheel guide means are located at least one rearwardly and at least one forwardly of a vertical plane extending transversely through the center of the wheel in use and arranged in such a manner that the product formed by the associated relative elasticity and the effective distance from said vertical plane of the elastic support means located rearwardly of said vertical plane is larger than the corresponding product of the forwardly located elastic support means.
