Abstract
Abstract An axle wherein the independent wheel carriers each rock around a transverse longitudinal member adapted to rock inside a corresponding dished support; each pair of parallel dished supports being interconnected by a hollow cross-beam and connected to the chassis through elastic means, a hydroelastic shock-absorbing suspension enclosed at each end of the cross-beam and bearing against the latter to control the rocking of the corresponding wheel carrier around the transverse axis through the agency of a lever rocking in unison with the wheel carrier around the same axis between predetermined limits.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
A vehicle axle for carrying at least one independently mounted wheel on at least one longitudinal suspension arm, which comprises: a. two dished suspension supports interconnected by at least one cross-beam member; b. elastic carrier means for securing the support members to a vehicle chassis; c. a transverse member mounted in each of the dished suspension supports; d. means for pivotally mounting the at least one longitudinal suspension arm on the transverse member so that the at least one longitudinal suspension arm is adapted to pivot about a transverse axis; e. hydroelastic suspension means acting as a shock absorber and mounted in the dished suspension supports for damping the pivotal motion of the at least one longitudinal suspension arm; and f. means adapted to pivot with the at least one longitudinal suspension arm for engaging the hydroelastic suspension means.
Claim 2
Dependent Claim
139 words
A vehicle axle for carrying at least one independently mounted wheel on at least one longitudinal suspension arm, which comprises: a. two dished suspension supports interconnected by at least one cross-beam member; b. elastic carrier means for securing the support members to a vehicle chassis; c. a transverse member mounted in each of the dished suspension supports; d. means for pivotally mounting the at least one longitudinal suspension arm on the transverse member so that the at least one longitudinal suspension arm is adapted to pivot about a transverse axis; e. hydroelastic suspension means acting as a shock absorber and mounted in the dished suspension supports for damping the pivotal motion of the at least one longitudinal suspension arm; and f. means adapted to pivot with the at least one longitudinal suspension arm for engaging the hydroelastic suspension means.
Claim 3
Dependent Claim
67 words
A vehicle axle as claimed in claim 1 wherein the means for engaging the hydroelastic suspension means comprises a lever rigid with the suspension arm, the lever pivoting round the transverse member and carrying at its opposite ends abutment shoes adapted to engage stops at the corresponding ends of the path over which the lever is allowed to travel under the action of the hydroelastic suspension means.
Claim 4
Dependent Claim
29 words
A vehicle axle as claimed in claim 1, wherein the cross-beam is hollow and encloses a part of the lengths of the transverse members carried by the dished supports.
Claim 5
Dependent Claim
33 words
A vehicle axle as claimed in claim 3 wherein the cross-beam has a U-shaped or Omega -shaped cross-section, the longitudinal opening of said cross-beam being closed at its outer ends by reinforcing struts.
Claim 6
Dependent Claim
42 words
A vehicle axle as claimed in claim 4 wherein each transverse member is secured to the cross-beam with the interposition of funnel-shaped annular supports which may be housed coaxially within the substantially cylindrical longitudinal portion of the cross-beam opposed to its opening.
Claim 7
Dependent Claim
31 words
A vehicle axle as claimed in claim 5, wherein each reinforcing strut includes an arcuate section engaging the outer surface of the corresponding funnel-shaped annular support to which it is welded.
Claim 8
Dependent Claim
33 words
A vehicle axle as claimed in claim 2 further comprising a bar for connecting two longitudinal arms, to oppose rolling motion of the longitudinal arms, the bar being housed within the hollow cross-beam.
Claim 9
Dependent Claim
36 words
A vehicle axle as claimed in claim 1 wherein the elastic carrier members are less rigid in a direction parallel with the longitudinal direction of the vehicle than in a transverse or in a vertical direction.
Claim 10
Dependent Claim
25 words
A vehicle axle as claimed in claim 1 wherein the dished suspension supports further comprise a concave area against which the hydroelastic suspension means bear.
