Abstract
Abstract An independent suspension for a driven wheel of a vehicle includes a trailing arm pivoted at one end to the wheel hub support and at the other end to the suspended body to transmit longitudinal (driving) stresses. The wheel is driven by a stub shaft which is connected to a differential via universal joints and which is effective to transmit transverse loads between the wheel hub support and the suspended body through the casing of the differential. A transverse link is pivoted between the wheel hub carrier and the body to prevent wobbling of the wheel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
330 words
In a vehicle having a suspended part and at least one rear wheel driven from a differential mounted to said vehicle, a suspension system for the wheel comprising in combination: a. a wheel hub support rotatably mounting said wheel, b. a rigid trailing arm extending between and articulated to said wheel hub support and to a single fixed point on said suspended part, said fixed point being located forwardly of the wheel, said trailing arm being adapted to take up longitudinal stresses, c. a vertically positioned shock absorber means having its lower end rigidly connected to said wheel hub support and its upper end connected to a point on said suspended part above the wheel, said shock absorber means being adapted to guide the wheel during upward and downward movement relative to said suspended part, d. spring means disposed between said suspended part and one of said trailing arm and wheel hub support, e. a stub shaft having a fixed length extending transversely between said differential and the wheel, said shaft having a universal joint attached to each end thereof, one of said universal joints being secured to said wheel and the other of said universal joints being drivingly connected to said differential, said stub shaft being adapted to transmit torque from the differential to the wheel and to transmit transverse loads from the wheel to said differential, and f. a transverse link extending between and articulated to a point on said wheel hub carrier rearwardly of said stub shaft and to a point on said suspended part, said transverse link being articulated to the suspended part for movement about a substantially horizontal longitudInal axis, said transverse link being positioned parallel to said stub shaft and located at substantially the same vertical level as said stub shaft, said link having a resilient bushing in at least one of its points of articulation, said transverse link adapted for securing and maintaining the static toe-in of said wheel at a predetermined value.
Claim 2
Dependent Claim
330 words
In a vehicle having a suspended part and at least one rear wheel driven from a differential mounted to said vehicle, a suspension system for the wheel comprising in combination: a. a wheel hub support rotatably mounting said wheel, b. a rigid trailing arm extending between and articulated to said wheel hub support and to a single fixed point on said suspended part, said fixed point being located forwardly of the wheel, said trailing arm being adapted to take up longitudinal stresses, c. a vertically positioned shock absorber means having its lower end rigidly connected to said wheel hub support and its upper end connected to a point on said suspended part above the wheel, said shock absorber means being adapted to guide the wheel during upward and downward movement relative to said suspended part, d. spring means disposed between said suspended part and one of said trailing arm and wheel hub support, e. a stub shaft having a fixed length extending transversely between said differential and the wheel, said shaft having a universal joint attached to each end thereof, one of said universal joints being secured to said wheel and the other of said universal joints being drivingly connected to said differential, said stub shaft being adapted to transmit torque from the differential to the wheel and to transmit transverse loads from the wheel to said differential, and f. a transverse link extending between and articulated to a point on said wheel hub carrier rearwardly of said stub shaft and to a point on said suspended part, said transverse link being articulated to the suspended part for movement about a substantially horizontal longitudInal axis, said transverse link being positioned parallel to said stub shaft and located at substantially the same vertical level as said stub shaft, said link having a resilient bushing in at least one of its points of articulation, said transverse link adapted for securing and maintaining the static toe-in of said wheel at a predetermined value.
Claim 3
Dependent Claim
23 words
The suspension system of claim 1, wherein said transverse link is of an adjustable length to permit static toe-in adjustment of the wheel.
Claim 4
Dependent Claim
60 words
The suspension system of claim 1, wherein the suspended part includes a transversely extending crossmember connected forward of the wheel and having a resilient mounting located midway along its length for receiving a longitudinal stationary sleeve, said sleeve enclosing an input drive transmission shaft connected to said differential, said trailing arm being articulated at its forward end to said crossmember.
Claim 5
Dependent Claim
61 words
The suspension system of claim 1, further comprising, a casing for housing said differential, and said suspended part includes a crossmember extending transversely to and being resiliently connected to the vehicle at points spaced apart along the length of the crossmember, said casing being rigidly connected to said crossmember, whereby, transverse stresses are transmitted through the stub shaft to the casing.
Claim 6
Dependent Claim
25 words
The suspension system of claim 4, wherein the point of articulation of said transverse link having said resilient bushing therein is attached to said crossmember.
Claim 7
Dependent Claim
49 words
The suspension system of claim 1, further comprising, a second rear wheel and like suspension system therefor, both of said rear wheels being driven from said differential, and including a stabilizer torque member of substantially U-shaped construction extending between and connected with the trailing arms of each wheel suspension.
