Abstract
Abstract The pivot axis of the lower one of a pair of superposed connections between a wheel mounting of a motor vehicle it tilted downwardly and rearwardly, and the upper one either tilted in the same direction or located rearwardly of the lower one, causing the wheel mounting to oscillate in a path inclined upwardly and rearwardly with respect to the direction of movement of the vehicle. The angles of inclination and tilt may vary from 10* to 30* . The upper and lower connections may be cross arms, for example, of the wishbone type, or leaf springs, and in certain cases, the upper connection may be by way of a resilient extensible strut.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
171 words
A suspension device for automotive vehicle wheels, comprising a wheel mounting, including the wheel spindle, having upper and lower supporting connections with the chassis of the vehicle, said lower connection comprising a member extending transversely outwardly with respect to the chassis, means connecting an inward portion of said connection with said chassis for approximately up and down movement flexing with relation to the chassis, the axis of said flexing movement inclined downwardly and rearwardly with respect to the direction of movement of the vehicle; said upper connection comprising means for hingedly connecting the upper portion of the wheel mounting to the chassis sufficiently rearwardly of the wheel spindle and of the lower connection that, together with the inclination of the lower connection, the path of oscillatory movement of the spindle is inclined rearwardly with regard to the direction of movement of the vehicle, the angle of inclination being a minimum of from about 10* to about 30*; said device including spring means for resilient suspension of the vehicle from the wheels.
Claim 2
Dependent Claim
171 words

Claim 3
Dependent Claim
52 words
A suspension device as set forth in claim 1, in which the spring means comprises an extensible resilient strut pivotally secured at its lower end to the lower portion of the wheel mounting and at its upper end to the chassis, this latter securement constituting the said upper connectiOn of the device.
Claim 4
Dependent Claim
28 words
The device as set forth in claim 2, in which the securement of the strut to the wheel mounting is at a point lower than the wheel spindle.
Claim 5
Dependent Claim
29 words
The device as set forth in claim 2, in which the lower connection comprises a cross arm having an inclined pivotal connection at its inward end with the chassis.
Claim 6
Dependent Claim
27 words
The device as set forth in claim 4, in which the attachment of the wheel mounting to the lower cross arm is displaced rearwardly of the strut.
Claim 7
Dependent Claim
41 words
The device as set forth in claim 2, in which the lower connection comprises a leaf spring the hinging connection of its inward end to the chassis confinning the angle of flexing of the spring to a rearward and downward angularity.
Claim 8
Dependent Claim
49 words
The device as set forth in claim 2, in which the securement of the strut to the chassis is such that, at all times, the angle of rearward inclination of the strut to the vertical is somewhat greater than the downward inclination of the lower connection to the horizontal.
Claim 9
Dependent Claim
20 words
The device as set forth in claim 2, in which the wheel spindle is displaced forwardly of the said strut.
Claim 10
Dependent Claim
46 words
The device as set forth in claim 1, in which both the upper and lower connections comprise laterally outwardly extending cross arms having pivotal securement to upper and lower portions of the chassis, the axis of both pivots being rearwardly and downwardly inclined to the horizontal.
Claim 11
Dependent Claim
33 words
The device as set forth in claim 9, in which the angle of the pivotal axis of the upper cross arm is from 5* to 10* greater than that of the lower one.
Claim 12
Dependent Claim
24 words
The device as set forth in claim 1, in which one of said connections comprises a cross arm and the other a leaf spring.
