Abstract
Abstract The present invention relates to an improved suspension for a group of wheels of a vehicle comprising longitudinal torsion bars coupled to the wheels outside longitudinal rails and to an elastic stabilizer bar by means of a connecting piece. According to the invention, the bar extends in a part beyond the torsion bar, which part is capable of abutting on an elastic stop placed between it and a fixed part of the structure when the load of the vehicle exceeds a certain threshold. The invention is more particularly applicable to automobile construction.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
An improvement in the suspension of a group of vehicle wheels comprising two wheels located respectively outside at least two longitudinal panels belonging to the structure of the vehicle, two suspension devices, each being constituted by at least one torsion bar substantially parallel to said panels connected at one of its ends to the corresponding wheel, and a transverse elastic member substantially perpendicular to said panels and anchored at the other end of each of the said torsion bars outside said panels, wherein each end of said elastic members extends beyond its anchorage to the corresponding torsion bar with respect to said panel in an end part extending opposite an element fast with said structure and there is disposed between said element and said end part an elastically deformable stop tending to restrain their relative approach beyond a determined load threshold of the vehicle.
Claim 2
Dependent Claim
144 words
An improvement in the suspension of a group of vehicle wheels comprising two wheels located respectively outside at least two longitudinal panels belonging to the structure of the vehicle, two suspension devices, each being constituted by at least one torsion bar substantially parallel to said panels connected at one of its ends to the corresponding wheel, and a transverse elastic member substantially perpendicular to said panels and anchored at the other end of each of the said torsion bars outside said panels, wherein each end of said elastic members extends beyond its anchorage to the corresponding torsion bar with respect to said panel in an end part extending opposite an element fast with said structure and there is disposed between said element and said end part an elastically deformable stop tending to restrain their relative approach beyond a determined load threshold of the vehicle.
Claim 3
Dependent Claim
27 words
Improvement as claimed in claim 1, wherein the step is carried by said end part of the elastic member and bears by simple contact on said element.
Claim 4
Dependent Claim
23 words
Improvements as claimed in claim 1, wherein said stop is fast with said element and bears by simple contact on said end part.
Claim 5
Dependent Claim
34 words
Improvement as claimed in any one of the preceding claims, wherein the stop is a cushion made of elastic material of such dimensions that it acts only from a determined load threshold mentioned above.
