Abstract
Abstract An independent wheel suspension system for a motor vehicle includes a trailing arm (70) mounted for pivotal resilient movement through pivotal connecting members (72, 74), carried in the vehicle chassis (78). Resilient pivotal connection to a strut assembly (10) is effected through ball stud (56). The configuration and positioning of the trailing arm (70) and its mountings (72, 74, 56) elevates the vehicle roll center and reduces toe-out of the vehicle wheels during recession. An economical stamped support structure (20) having a spindle support member (36) and a strut support member (38) is utilized in the system. A combination spring seat and steering arm (22) is fixed to the top of the strut support member (38).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
121 words
An independent wheel suspension system for the steerable wheels of a vehicle of the type wherein a resiliently telescoping strut assembly is interposed between the wheel and a portion of the vehicle body at each wheel and a trailing arm member is pivotally mounted to the wheel and strut assembly and is pivotally mounted to the vehicle chassis forwardly of the wheel, characterized in that the strut assembly includes a telescoping portion and a support portion comprising a strut support stamping fixedly secured to the telescoping portion and a spindle support stamping attached to the strut support stamping to form a unitary structure, the strut support stamping having portions integrally formed therewith for effecting pivotal connection with the trailing arm member.
Claim 2
Dependent Claim
121 words
An independent wheel suspension system for the steerable wheels of a vehicle of the type wherein a resiliently telescoping strut assembly is interposed between the wheel and a portion of the vehicle body at each wheel and a trailing arm member is pivotally mounted to the wheel and strut assembly and is pivotally mounted to the vehicle chassis forwardly of the wheel, characterized in that the strut assembly includes a telescoping portion and a support portion comprising a strut support stamping fixedly secured to the telescoping portion and a spindle support stamping attached to the strut support stamping to form a unitary structure, the strut support stamping having portions integrally formed therewith for effecting pivotal connection with the trailing arm member.
Claim 3
Dependent Claim
84 words
An independent wheel suspension system as defined in claim 1, further characterized in that a spring is carried in surrounding relationship about the telescoping portion received at its upper end by upper seat carried with the vehicle body, and a lower seat member is fixed to the upper end of the strut support stamping for receiving the lower end of the spring, the lower seat member having integrally formed therewith a radially extending steering arm portion connectable to the steering system of the vehicle.
Claim 4
Dependent Claim
23 words

Claim 5
Dependent Claim
52 words
An independent wheel suspension system as defined in claim 1, further characterized in that the strut support stamping includes apertures formed therethrough in axial registration with the portions of the telescoping strut assembly and weldments are provided at the apertures for fixedly securing the strut support stamping to the strut assembly portions.
Claim 6
Dependent Claim
126 words
An independent wheel suspension system for the steerable wheels of a vehicle of the type wherein a resiliently telescoping strut assembly is interposed between the wheel and a portion of the vehicle body at each wheel and a trailing arm member is pivotally mounted to the wheel and strut assembly and is pivotally mounted to the vehicle chassis forwardly of the wheel, characterized in that a support portion is provided attached to the telescoping portion and the vehicle wheel and a dish-like spring support member is fixed to one of the upper end of the strut support stamping or the telescoping strut assembly to define the spring lower seat and a radially extending arm portion is integrally formed therewith for attachment to a vehicle steering system.
Claim 7
Dependent Claim
126 words
An independent wheel suspension system for the steerable wheels of a vehicle of the type wherein a resiliently telescoping strut assembly is interposed between the wheel and a portion of the vehicle body at each wheel and a trailing arm member is pivotally mounted to the wheel and strut assembly and is pivotally mounted to the vehicle chassis forwardly of the wheel, characterized in that a support portion is provided attached to the telescoping portion and the vehicle wheel and a dish-like spring support member is fixed to one of the upper end of the strut support stamping or the telescoping strut assembly to define the spring lower seat and a radially extending arm portion is integrally formed therewith for attachment to a vehicle steering system.
Claim 8
Dependent Claim
