Abstract
Abstract In motor vehicles, in particular passenger cars possessing an axle or axles with steerable wheels, the steering-gear box is conventionally located asymmetrically with respect to the center-line. The result of this on the steering linkage is that the linkage part-sections between the steering-gear box and each of the wheels are of different design. This asymmetry can give rise to differences in the wear of the tires on these wheels, and is advantageously avoided according to this invention by making the overall stiffness values of the two part-sections identical, irrespective of the design-differences.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
98 words
Motor vehicle, in particular a passenger car, possessing an axle with steerable wheels, on which axle the wheels are connected to a steering-gear box via a steering linkage which, starting from the steering box, is composed of two part sections containing a plurality of linkage member connection joints, each part section including joints of different construction than the joints of the other part section each part section interconnecting one of the wheels with the steering-gear box, wherein the overall stiffness of one of the two part sections is equal to the overall stiffness of the other part section.
Claim 2
Dependent Claim
98 words
Motor vehicle, in particular a passenger car, possessing an axle with steerable wheels, on which axle the wheels are connected to a steering-gear box via a steering linkage which, starting from the steering box, is composed of two part sections containing a plurality of linkage member connection joints, each part section including joints of different construction than the joints of the other part section each part section interconnecting one of the wheels with the steering-gear box, wherein the overall stiffness of one of the two part sections is equal to the overall stiffness of the other part section.
Claim 3
Dependent Claim
57 words
Motor vehicle according to claim 1, the two part-sections possessing different numbers of joints, wherein the joints of the two part-sections are designed to have stiffness values such that the total stiffness of the joints which are located in one part-section is equal to the total stiffness of the joints which are located in the other part-section.
Claim 4
Dependent Claim
19 words
Motor vehicle according to claim 2, wherein the joints of one part-section are, in each case, identical among themselves.
Claim 5
Dependent Claim
109 words
A wheel suspension arrangement for a pair of steerable wheels on a vehicle which has a steering box disposed at one side of the vehicle, comprising a first steering linkage section interconnecting the steering box with a first of the steerable wheels, a second steering linkage section interconnecting the steering box with a second of the steerable wheels, said second steering linkage section including joints of different construction than joints of said first steering linkage section, wherein the overall stiffness resistance of the first and second linkage section is equal, whereby the asymmetrical location of the steering box is accommodated for and even tire-wear is obtained at both wheels.
Claim 6
Dependent Claim
109 words
A wheel suspension arrangement for a pair of steerable wheels on a vehicle which has a steering box disposed at one side of the vehicle, comprising a first steering linkage section interconnecting the steering box with a first of the steerable wheels, a second steering linkage section interconnecting the steering box with a second of the steerable wheels, said second steering linkage section including joints of different construction than joints of said first steering linkage section, wherein the overall stiffness resistance of the first and second linkage section is equal, whereby the asymmetrical location of the steering box is accommodated for and even tire-wear is obtained at both wheels.
Claim 7
Dependent Claim
47 words
An arrangement according to claim 4, wherein each of said linkage sections include a plurality of linkage member connection joints, and wherein the total stiffness of the joints in the first linkage section is equal to the total stiffness of the joints in the second linkage section.
Claim 8
Dependent Claim
18 words
An arrangement according to claim 5, wherein the first and second linkage sections have different members of joints.
Claim 9
Dependent Claim
19 words
An arrangement according to claim 6, wherein the joints in the first linkage section all have the same stiffness.
Claim 10
Dependent Claim
19 words
An arrangement according to claim 7, wherein the joints in the second linkage section all have the same stiffness.
Claim 11
Dependent Claim
34 words
An arrangement according to claim 8, wherein the steering box is located at the side of the first wheel, and wherein the first linkage section has fewer joints than does the second linkage section.
Claim 12
Dependent Claim
34 words
An arrangement according to claim 5, wherein the steering box is located at the side of the first wheel, and wherein the first linkage section has fewer joints than does the second linkage section.
