Abstract
Abstract A rear beam axle for a road vehicle is mounted on the vehicle body by leaf spring assemblies. The rear end of each assembly is mounted on the body by resilient mounts offering greater resistance to displacement transverse the vehicle then to displacement in the fore and aft direction of the vehicle. The front end of each assembly is mounted on the body by resilient mounts having greater resistance to the displacement of the front end of the assembly relative to the structure in a direction of an oblique axis extending from the second resilient means to a point behind the axle midway between the first resilient means than to displacement of the front end of the assembly in a direction parallel to the ground plane and at right angles to the oblique axis.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
277 words
In a rear wheel suspension for a vehicle having a beam axle which supports the vehicle structure through two leaf spring assemblies, disposed perpendicular to and near opposite ends of the axle; the rear end of each assembly being coupled to the vehicle structure by rear resilient means having greater resistance to displacement of the rear end of the assembly relative to the structure in a direction parallel to the ground plane and parallel to the axle than to displacement of the rear end in a direction parallel to the ground plane and at right angles to the axle; the improvement comprising: first front resilient means coupling the front end of one assembly to the vehicle structure and second front resilient means coupling the front end of the other assembly to said structure, said first front resilient means providing greater resistance displacement of the front end of said one assembly relative to the structure in the direction of a first line extending from said first front resilient means to a point behind said axle midway between said rear resilient means than to the displacement of the front end of the assembly in a direction parallel to the ground plane and at right anGles to said line, while said second front resilient means provides a greater resistance to the displacement of the front end of the other of said assemblies relative to the structure in the direction of a second line extending from said second front resilient means to said point than to the displacement of the front end of said other assembly in a direction parallel to the ground plane and at right angles to said line.
Claim 2
Dependent Claim
277 words
In a rear wheel suspension for a vehicle having a beam axle which supports the vehicle structure through two leaf spring assemblies, disposed perpendicular to and near opposite ends of the axle; the rear end of each assembly being coupled to the vehicle structure by rear resilient means having greater resistance to displacement of the rear end of the assembly relative to the structure in a direction parallel to the ground plane and parallel to the axle than to displacement of the rear end in a direction parallel to the ground plane and at right angles to the axle; the improvement comprising: first front resilient means coupling the front end of one assembly to the vehicle structure and second front resilient means coupling the front end of the other assembly to said structure, said first front resilient means providing greater resistance displacement of the front end of said one assembly relative to the structure in the direction of a first line extending from said first front resilient means to a point behind said axle midway between said rear resilient means than to the displacement of the front end of the assembly in a direction parallel to the ground plane and at right anGles to said line, while said second front resilient means provides a greater resistance to the displacement of the front end of the other of said assemblies relative to the structure in the direction of a second line extending from said second front resilient means to said point than to the displacement of the front end of said other assembly in a direction parallel to the ground plane and at right angles to said line.
Claim 3
Dependent Claim
156 words
A rear wheel suspension as claimed in claim 1 wherein the front end of said one assembly is in the form of a first scroll bent around an axis perpendicular to said first line, the front end of said other assembly is in the form of a second scroll bent about an axis perpendicular to said second line, said first front resilient means is a first annular bush of resilient material having a longitudinal axis perpendicular to said first line, said second front resilient means is a second annular bush of material having a longitudinal axis perpendicular to said second line, each bush defining an inner and an outer curved surface, said supension comprising means securing the vehicle structure to the inner curved surface of each bush, said first scroll being secured to the outer curved surface of said first bush and said second scroll being secured to the outer curved surface of said second bush.
Claim 4
Dependent Claim
152 words
A rear wheel suspension as claimed in claim 1 wherein the front end of said one assembly is in the form of a first scroll and the front end of said other assembly is in the form of a second scroll, said first front resilient means is a first annular bush of resilient material having a longitudinal axis perpendicular to said one assembly, said second front resilient means is a second annular bush of resilient material perpendicular to said other assembly, said suspension comprising means securing the vehicle structure to the inner surface of each bush, said first bush having a maximum thickness of resilient material in the direction of said first line and a minimum thickness in a direction perpendicular thereto, while the second bush has a maximum thickness of resilient material in the direction of said second line and a minimum thickness in a direction perpendicular to said second line.
Claim 5
Dependent Claim
155 words
A rear wheel suspension as claimed in claim 1 wherein the front end of said one assembly is secured to a first rigid component having ends projecting outwardly on both sides of said one assembly, while the other assembly is secured to a second rigid component having ends projecting on both sides of said other assembly, said first and second front resilient means consisting of first and second resilient block means respectively, in which block means the ends of said first and second rigid components are respectively mounted, said first block means having a maximum thickness of resilient material in the direction of said first line and a minimum thickness of resilient material in a direction perpendicular to said first line, while said second block means has a maximum thickness of resilient material in the direction of said second line and a minimum thickness of resilient material in a direction perpendicular to said second line.
