Abstract
Abstract A linkage is pivotally connected to the frame of the vehicle and serves as a mounting for the vehicle wheel so that the vehicle wheel can pivot relatively to the frame in a vertical direction and the linkage is also journaled for movement on a horizontal axis causing pairs of interconnected wheels to be banked. Each wheel of the vehicle, whether power driven or steerable, can independently move vertically against a spring action for suspension of the vehicle and one or more pairs of such wheels are banked by turning movements on a respective horizontal axis. The banking of the wheel is in proportion to the steering of the vehicle. The front set or rear set, or both sets can be banked but in every event the pairs are banked in unison.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
A suspension apparatus for vehicles comprising a vehicle frame, support linkage means having a pivoted connection with said frame and adapted to receive a vehicle wheel to provide movement thereof in a vertical plane relatively to said frame, means for journaling said support linkage on said frame whereby the linkage and attached wheel can turn angularly to provide banking movement of said wheel in combination with vertical pivotal movement of said support linkage, means for effecting turning of said linkage on said journaling means and comprised of a power cylinder having a fluid connection with the steering system of said vehicle whereby the steering of the vehicle and banking of the wheel are coordinated together while concurrently providing vertical cushioning movement.
Claim 2
Dependent Claim
121 words
A suspension apparatus for vehicles comprising a vehicle frame, support linkage means having a pivoted connection with said frame and adapted to receive a vehicle wheel to provide movement thereof in a vertical plane relatively to said frame, means for journaling said support linkage on said frame whereby the linkage and attached wheel can turn angularly to provide banking movement of said wheel in combination with vertical pivotal movement of said support linkage, means for effecting turning of said linkage on said journaling means and comprised of a power cylinder having a fluid connection with the steering system of said vehicle whereby the steering of the vehicle and banking of the wheel are coordinated together while concurrently providing vertical cushioning movement.
Claim 3
Dependent Claim
169 words
In a vehicle suspension system for a vehicle, said vehicle having a frame and at least a wheel in ground engagement, means for driving said wheel and including an elongatable drive shaft and a U-joint operatively connected to said wheel, means pivotally mounting said wheel for compound movements about longitudinal and lateral axes on said frame to provide for vertical and angular wheel movement about said axes, resilient means incorporated within said mounting means to be unopposed to angular wheel movement and yieldably opposing pivoting of said wheel in a vertical plane to provide for cushioning between the ground and vehicle through said wheel and for applying a restoring force on said wheel when the forces producing pivoting are relieved, means for journalling said pivotally mounting means to provide for angular banking movement of said wheel in a transverse vertical plane whereby the wheel is disposed at an angular banked position for stabilized vehicle turning, and means forming a support connection between said wheel mounting means and said frame.
Claim 4
Dependent Claim
169 words
In a vehicle suspension system for a vehicle, said vehicle having a frame and at least a wheel in ground engagement, means for driving said wheel and including an elongatable drive shaft and a U-joint operatively connected to said wheel, means pivotally mounting said wheel for compound movements about longitudinal and lateral axes on said frame to provide for vertical and angular wheel movement about said axes, resilient means incorporated within said mounting means to be unopposed to angular wheel movement and yieldably opposing pivoting of said wheel in a vertical plane to provide for cushioning between the ground and vehicle through said wheel and for applying a restoring force on said wheel when the forces producing pivoting are relieved, means for journalling said pivotally mounting means to provide for angular banking movement of said wheel in a transverse vertical plane whereby the wheel is disposed at an angular banked position for stabilized vehicle turning, and means forming a support connection between said wheel mounting means and said frame.
Claim 5
Dependent Claim
50 words
The vehicle suspension system according to claim 2 wherein said resilient means is disposed at a vertical level above said pivotally mounting means and carried by said pivotally mounting means to the same angular displacements as said wheel whereby such angular banking movements are substantially unopposed by said resilient means.
Claim 6
Dependent Claim
42 words
The vehicle suspension system in accordance with claim 2 wherein said vehicle is provided with a pair of positively driven rear wheels and wherein two said suspension systems are provided one in combination with each of said positively driven vehicle rear wheels.
Claim 7
Dependent Claim
37 words
The vehicle suspension system in accordance with claim 2 including power actuating means for effecting banking of said wheel, and means combined with the steering system of the vehicle to effect steering and banking in proportional amounts.
Claim 8
Dependent Claim
37 words
The vehicle suspension system in accordance with claim 2 including a plurality of driven wheels and a pair of said suspension systems one for each of said driven wheels, and knuckle mounting means for receiving said wheels.
Claim 9
Dependent Claim
55 words
The suspension system apparatus in accordance with claim 2 wherein said vehicle includes a plurality of wheels and means for effecting turning of said wheels and comprised of a power cylinder having a fluid connection with the steering system of said vehicle and to effect simultaneous steering and banking of said wheels in coordinated movements.
Claim 10
Dependent Claim
151 words
In a vehicle suspension system for a vehicle having a frame and vehicle wheels in ground engagement, means for driving said wheel, means pivotally mounting said wheel for compound movements about longitudinal and lateral axes on said frame to provide for vertical and angular wheel movements about said aXes, resilient means incorporated within said mounting means to be unopposed to angular wheel movement and yieldably opposing pivoting of said wheel in a vertical plane to provide for cushioning between the ground and vehicle through said wheel and for applying a restoring force on said wheel when the forces producing pivoting are relieved, means for journalling said pivotally mounting means to provide for angular banking movement of said wheel in a transverse vertical plane whereby the wheels are disposed at an angular banked position for stabilized vehicle turning, and means forming a support connection between said wheel mounting means and same frame.
