Abstract
Abstract A vehicle suspension system of the type having a load-bearing axial support. The suspension system is provided with leaf-springs coupling the support to wheel axles of the vehicle such that in normal operation the suspension means are pivotable about the support. Radius rods are pivotally coupled between the wheel axles and a leaf-spring member located above the load-bearing axial support which, in combination, resists the pivoting of the wheel axles about the load-bearing axial support.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
In a vehicle suspension system of the type having a load-bearing axial support including means for securing said support to said vehicle and suspension means in the form of leaf-springs coupling said support to wheel axles of said vehicles such that in normal operation said suspension means are pivotable about said support, the improvement in said vehicle suspension system comprising radius rod members each pivotally coupled between said wheel axles and a leaf-spring member located above said load-bearing axial support, said leaf-spring member comprising a steel plate having a thickness of approximately one inch or greater to resist significant flexure upon movement of said wheel axles conveyed through said radius rods, the combination of said radius rods and leaf-spring member being sufficient to substantially resist the pivoting of said wheel axles about said load-bearing axial support.
Claim 2
Dependent Claim
136 words
In a vehicle suspension system of the type having a load-bearing axial support including means for securing said support to said vehicle and suspension means in the form of leaf-springs coupling said support to wheel axles of said vehicles such that in normal operation said suspension means are pivotable about said support, the improvement in said vehicle suspension system comprising radius rod members each pivotally coupled between said wheel axles and a leaf-spring member located above said load-bearing axial support, said leaf-spring member comprising a steel plate having a thickness of approximately one inch or greater to resist significant flexure upon movement of said wheel axles conveyed through said radius rods, the combination of said radius rods and leaf-spring member being sufficient to substantially resist the pivoting of said wheel axles about said load-bearing axial support.
Claim 3
Dependent Claim
28 words
The vehicle suspension system of claim 1 wherein said leaf-spring member is held in position above said load-bearing axial support by U-bolts connected to said load-bearing axial support.
Claim 4
Independent Claim
133 words
A method for improving a vehicle suspension system which comprises a load-bearing axial support including means for securing said support to said vehicle and suspension means in the form of leaf-springs coupling said support to wheel axles of said vehicle such that in normal operation said suspension means are pivotable about said support, the method comprising pivotally attaching radius rod members between said wheel axles and a leaf-spring member which itself is attached above said load-bearing axial support, said leaf-spring member comprising a steel plate having a thickness of approximately one inch or greater to resist significant flexure upon movement of said wheel axles conveyed through said radius rods, the combination of said radius rods and leaf-spring members being sufficient to substantially resist pivoting of said wheel axles about said load-bearing axial support.
Claim 5
Independent Claim
133 words
A method for improving a vehicle suspension system which comprises a load-bearing axial support including means for securing said support to said vehicle and suspension means in the form of leaf-springs coupling said support to wheel axles of said vehicle such that in normal operation said suspension means are pivotable about said support, the method comprising pivotally attaching radius rod members between said wheel axles and a leaf-spring member which itself is attached above said load-bearing axial support, said leaf-spring member comprising a steel plate having a thickness of approximately one inch or greater to resist significant flexure upon movement of said wheel axles conveyed through said radius rods, the combination of said radius rods and leaf-spring members being sufficient to substantially resist pivoting of said wheel axles about said load-bearing axial support.
Claim 6
Dependent Claim
26 words
The method of claim 3 wherein said leaf-spring member is held in position above said load-bearing axial support by U-bolts connected to said load-bearing axial support.
