Abstract
Abstract A three-guide member wheel suspension in which the wheel carrier is connected with the vehicle body or the like by way of three guide members pivotally connected at the vehicle body. The three guide members consist of a longitudinal guide arm, an upper cross guide member and a lower cross guide member. In order to be able to realize an effective center of rotation for the wheel carrier which lies clearly above the wheel axle in order to obtain with a rear axle a good accelerating pitching compensation and a good deceleration pitching compensation, the longitudinal arm is pivotally connected with the wheel carrier. Additionally, the upper cross guide member is pivotally connected intermediate its joint on the wheel carrier side and its joint on the body side with one end of a support strut which pivotally engages with its other end at the longitudinal arm between the pivot axis at the wheel carrier and the forward bearing support of the wheel carrier.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
169 words
An independent wheel suspension for motor vehicles, comprising wheel carrier means supporting a vehicle wheel, a relatively fixed vehicle part, means connecting the wheel carrier means with said fixed vehicle part including three guide means pivotally connected at said fixed vehicle part, one of said guide means being a longitudinal arm extending generally in the vehicle longitudinal direction and the other two guide means being cross guide members disposed one above the other and extending at least approximately in the vehicle transverse direction which are pivotally connected at the relatively fixed part and at the wheel carrier means by joint means, the wheel carrier means being pivotally arranged at said longitudinal arm, and support strut means, one of said cross guide members being pivotally connected intermediate its joint means on the wheel carrier side and its joint means on the side of the relatively fixed part with one end of the support strut means while the support strut means pivotally engages with its other end at the longitudinal arm.
Claim 2
Dependent Claim
169 words
An independent wheel suspension for motor vehicles, comprising wheel carrier means supporting a vehicle wheel, a relatively fixed vehicle part, means connecting the wheel carrier means with said fixed vehicle part including three guide means pivotally connected at said fixed vehicle part, one of said guide means being a longitudinal arm extending generally in the vehicle longitudinal direction and the other two guide means being cross guide members disposed one above the other and extending at least approximately in the vehicle transverse direction which are pivotally connected at the relatively fixed part and at the wheel carrier means by joint means, the wheel carrier means being pivotally arranged at said longitudinal arm, and support strut means, one of said cross guide members being pivotally connected intermediate its joint means on the wheel carrier side and its joint means on the side of the relatively fixed part with one end of the support strut means while the support strut means pivotally engages with its other end at the longitudinal arm.

Claim 8
Dependent Claim
20 words
A wheel suspension according to claim 6, wherein the upper cross guide member is connected with the support strut means.
Claim 9
Dependent Claim
27 words
A wheel suspension according to claim 7, wherein the support strut means extends from the upper cross guide member to the longitudinal arm obliquely forwardly and downwardly.
Claim 10
Dependent Claim
59 words
An independent wheel suspension according to claim 1, wherein said longitudinal arm is connected with the relatively fixed part by way of a transversely elastic bearing means, further comprising an approximately transversely directed auxiliary guide member which engages at said longitudinal arm, said auxiliary guide member being pivotally connected, on the other hand, with said relatively fixed vehicle part.
Claim 11
Dependent Claim
