Abstract
Abstract In a vehicle banking arm suspension each banking arm employs a flexible torsion spring member with means to stiffen it against flexing in the generally vertical direction. The spring specifically disclosed is a single leaf of generally uniform width and thickness disposed substantially horizontal and reinforced against vertical bending by one or more cables extending from end to end thereof and secured to the ends with an adjustable spacer arching the cable away from the leaf intermediate the ends to provide a truss.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
215 words
In a vehicle of the class described having a superstructure, a banking support for the superstructure connecting the superstructure on its forward end to a wheel spindle carrying wheel supported rigid front axle structure and on its rearward end to a rigid wheel supported rear axle housing structure and comprising a plurality of pairs of cooperating roll banking arms, each arm including a longitudinally extending torsionally resilient support connected by a ball and socket joint at one end to the superstructure and at the other end to the respective rigid axle, a side lever arm protruding from the respective torsionally resilient support and bearing at its end against a resilient multiturn cushion of polyurethane-based material placed near the end of the torsionally resilient support where axle supported and a side lever arm protruding from the respective torsionally resilient support and bearing at its end against a resilient multiturn cushion of polyurethane-based material placed intermediate the length of the torsionally resilient support where superstructure supported, and means including a member strong in tension but flexible in torsion secured to and coextensive with one side of said support to increase the resistance of said torsionally resilient support against flexing in a vertical direction to control the vertical positioN of the superstructure relative to the rigid axle structure.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
81 words
The construction of claim 1 in which each said torsionally resilient support comprises the combination of a torsionally operable spring leaf disposed generally in one of said planes, and said last named means comprises a truss cable secured at its ends to the ends of said spring leaf, and a center spacer disposed between said cable and leaf to provide a truss against flexing in the general vertical plane of the cable without substantial interference with torsional twist of said leaf.
Claim 4
Dependent Claim
19 words
The construction of claim 2 in which said center spacer is adjustable to regulate the tension of said cable.
Claim 5
Dependent Claim
27 words
The construction of claim 2 in which said spring leaf is disposed in a generally horizontal plane and said cable truss lies in a generally vertical plane.
Claim 6
Dependent Claim
17 words
The construction of claim 2 in which a cable is provided both above and below the leaf.
Claim 7
Dependent Claim
37 words
The construction of claim 2 in which each cable is comprised of a plurality of wire strands wound in a direction to supplement the torsional resistance of the spring leaf in supporting the weight of the vehicle.
