Abstract
Abstract A hydraulic or pneumatic servo arrangement which is controlled in response to the rotation of the steering wheel is connected to member of a rear suspension in a manner to apply a bias thereto which distorts an elastomeric insulator or insulators forming part of suspension so as to steer the wheel or wheels associated with the member in the same direction as the front wheels are steered.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
98 words
In a suspension arrangement for a vehicle having a chassis and a steering wheel, an elastomeric member; a first member operatively connected to said chassis through said elastomeric member; a road wheel operatively connected with said first member; and an arrangement responsive to said vehicle being steered which is operatively connected to said first member for applying a bias to said elastomeric member in a manner to change the orientation of said road wheel with respect to the longitudinal axis of said chassis and steer the road wheel in the same direction as the vehicle is being steered.
Claim 2
Dependent Claim
98 words
In a suspension arrangement for a vehicle having a chassis and a steering wheel, an elastomeric member; a first member operatively connected to said chassis through said elastomeric member; a road wheel operatively connected with said first member; and an arrangement responsive to said vehicle being steered which is operatively connected to said first member for applying a bias to said elastomeric member in a manner to change the orientation of said road wheel with respect to the longitudinal axis of said chassis and steer the road wheel in the same direction as the vehicle is being steered.
Claim 3
Dependent Claim
79 words
A suspension system as claimed in claim 1, wherein said device includes: an extensible strut interconnecting said chassis and said first member; a steering sensor operatively connected with said steering wheel for outputting a signal indicative of the vehicle being steered; a source of fluid under pressure; a valve responsive to the output of said steering sensor and operatively connected with said extensible strut for supplying fluid under pressure thereto in response to the output of said steering sensor.
Claim 4
Dependent Claim
42 words
A suspension system as claimed in claim 1, wherein said first member is connected to said chassis through said elastomeric member and said road wheel is operatively connected to said first member through a second member pivotally mounted on said first member.
Claim 5
Dependent Claim
127 words
In a suspension for a vehicle having a chassis and a steering wheel, an elastomeric member; a first member operatively connected to said chassis through said elastomeric member; a road wheel operatively connected with said first member; and an arrangement responsive to said vehicle being steered which is operatively connected to said first member for applying a bias to said elastomeric member in a manner to change the orientation of said road wheel with respect to the longitudinal axis of said chassis and steer the road wheel in the same direction as the vehicle is being steered, wherein said first member is connected to said chassis through a first pivot having a first axis of rotation, and wherein said elastomeric member forms part of said first pivot.
Claim 6
Dependent Claim
127 words
In a suspension for a vehicle having a chassis and a steering wheel, an elastomeric member; a first member operatively connected to said chassis through said elastomeric member; a road wheel operatively connected with said first member; and an arrangement responsive to said vehicle being steered which is operatively connected to said first member for applying a bias to said elastomeric member in a manner to change the orientation of said road wheel with respect to the longitudinal axis of said chassis and steer the road wheel in the same direction as the vehicle is being steered, wherein said first member is connected to said chassis through a first pivot having a first axis of rotation, and wherein said elastomeric member forms part of said first pivot.
Claim 7
Dependent Claim
65 words
A suspension as claimed in claim 4, wherein said elastomeric member is less rigid in the direction of said axis of rotation of said pivot than in a direction normal thereto, and wherein said arrangement responsive to the steering of said vehicle is arranged to apply a bias to said first member which distorts said elastomeric member in said direction of said axis of rotation.
Claim 8
Dependent Claim
45 words
A suspension arrangement as claimed in claim 4, further comprising a second pivot device interconnecting said first member with said chassis, said second pivot device being arranged so that the axis of rotation thereof intersects said first axis of rotation of said first pivot device.
