Abstract
Abstract Each half set of wheels comprises a telescopic shock absorber - suspension spring assembly which is fixed in its upper part to the body of the vehicle and is rigid in its lower part with, on one hand, a ball of a ball joint articulation of a suspension arm and, on the other hand, a hub support. The hub support comprises a stub-axle supporting side member connected by upwardly extending inclined branches to the sleeve supporting the body of the shock absorber. In its lower part, the side member carries a second ball joint articulation of a lower suspension arm and the transverse transmission extends between the lower and upper suspension arms. The centers of the two ball joint articulations are in alignment on the axis of the shock absorber.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
196 words
A front set of vehicle wheels comprising in combination, for each wheel of the set, a wheel hub support, an upper suspension arm, a suspension arm located below the upper arm and shorter than the upper arm, a telescopic shock absorber-suspension spring assembly having an axis of telescopic operation and fixed to the hub support at a lower end of the shock absorber-suspension spring assembly, means for connecting an upper end of the shock absorber-suspension spring assembly to the vehicle, a ball joint articulation connecting the telescopic shock absorber-suspension spring assembly to the upper suspension arm, and a second ball joint articulation connecting the hub support to the lower suspension arm, the two ball joint articulations having centres which are in fixed alignment on said axis of the shock absorber-suspension spring assembly and pivotal means provided adjacent to ends of the suspension arms opposed to said ball joint articulations for pivotally mounting the arms on the vehicle, said pivotal means of at least one of the arms being sufficiently elastically yieldable in operation of the arms for accommodating the fact that one of said ball joint articulations does not travel on an arc of a circle.
Claim 2
Dependent Claim
196 words
A front set of vehicle wheels comprising in combination, for each wheel of the set, a wheel hub support, an upper suspension arm, a suspension arm located below the upper arm and shorter than the upper arm, a telescopic shock absorber-suspension spring assembly having an axis of telescopic operation and fixed to the hub support at a lower end of the shock absorber-suspension spring assembly, means for connecting an upper end of the shock absorber-suspension spring assembly to the vehicle, a ball joint articulation connecting the telescopic shock absorber-suspension spring assembly to the upper suspension arm, and a second ball joint articulation connecting the hub support to the lower suspension arm, the two ball joint articulations having centres which are in fixed alignment on said axis of the shock absorber-suspension spring assembly and pivotal means provided adjacent to ends of the suspension arms opposed to said ball joint articulations for pivotally mounting the arms on the vehicle, said pivotal means of at least one of the arms being sufficiently elastically yieldable in operation of the arms for accommodating the fact that one of said ball joint articulations does not travel on an arc of a circle.
Claim 3
Dependent Claim
48 words
A front set of wheels as claimed in claim 1, in combination with a central differential and a hub supported by the hub support of each wheel, wherein a transverse transmission connects the hub to the central differential and extends between the two suspension arms of each wheel.
Claim 4
Dependent Claim
64 words
A front set of wheels as claimed in claim 1, comprising a tubular stub-axle support for each wheel, said shock absorber having a body and the hub support comprising a cylindrical sleeve for fixing to the body of the shock absorber, said sleeve being provided with two lateral downwardly extending branches which are fixed to a side member for supporting the tubular stub-axle support.
Claim 5
Dependent Claim
38 words
A front set of wheels as claimed in claim 3, wherein the hub support carries a ball joint support plate in the lower part of the hub support below the tubular stub-axle and on the opposite side thereof.
Claim 6
Dependent Claim
52 words
A front set of wheels as claimed in claim 1, in combination with side members of a chassis of the vehicle, and a cradle fixed to and under said side members, said lower suspension arm being pivotally mounted on the cradle and said upper suspension arm being pivotally mounted on the chassis.
Claim 7
Dependent Claim
39 words
A front set of wheels as claimed in claim 5, wherein the cradle comprises two tubes which are bent at end portions thereof and are each fixed by said end portions to a respective one of said side members.
Claim 8
Dependent Claim
49 words
A front set of wheels as claimed in claim 6, wherein the cradle comprises, in respect of each wheel, a second longitudinal tube which is parallel to the corresponding bent tube and is fixed at one end of the second longitudinal tube to a cross-member fixed to the chassis.
Claim 9
Dependent Claim
28 words
A front set of wheels as claimed in claim 6 or 7, further comprising a protecting plate mounted on the cradle below a transverse transmission for the wheels.
Claim 10
Dependent Claim
31 words
A front set of wheels as claimed in claim 1, wherein said pivotal means of said at least one of the arms comprises an elastomeric sleeve of the silent block type.
Claim 11
Dependent Claim
23 words
A front set of wheels as claimed in claim 1 or 9, wherein at least one of the arms is the lower arm.
