US Classification:

280124175, 28012417, 267 361, 267 40, 267148, 267149, 267260, 267269
Abstract:

A leaf spring for a vehicle suspension is formed from a composite material and includes first and second ends that are longitudinally spaced apart from each other. A resilient element is attached to at least one of the first and second ends. The resilient element includes at least one hole that receives a connecting element. The resilient element and the connecting element cooperate to attach the leaf spring to a vehicle structure. In one example, the resilient element comprises a rubber block that is bonded to the leaf spring. In another example, the resilient element comprises a longitudinally orientated bushing that is inserted through a thickness of the leaf spring.

International Classification:

F16F 1/18
B60G 11/10
US Classification:

267260, 267158
Abstract:

A leaf spring for a vehicle suspension is formed from a composite material and includes at least one spring end with a curved recess. A bushing assembly is attached to the curved recess. The bushing assembly includes a mounting component and a bushing that is attached to the mounting component such that the leaf spring can be pivotally attached to a vehicle frame. The mounting component is formed around an outer periphery of the curved recess to secure the mounting component to the leaf spring such that the bushing is received within the curved recess.

International Classification:

B60G 11/04
US Classification:

280124176
Abstract:

A leaf spring for a vehicle suspension is formed from a composite material and includes a central portion to be supported by an axle and at least one free end that extends from the central portion in a longitudinal direction. The free end is coupled to a vehicle structure via a slider bracket. A contact element is mounted to the slider bracket to contact an upper surface of the free end to accommodate vertical forces. The free end is slidably movable relative to the contact element along a longitudinal axis and is pivotable relative to the contact element about a lateral axis.

US Patent:

48941085, Jan 16, 1990
Filed:

Oct 17, 1988
Appl. No.:

7/258757
Inventors:

David S. Richard - Dayton OH
John E. Mutzner - Covington OH
John F. Eilerman - Dayton OH
Thomas E. Rau - Dayton OH
Assignee:

General Motors Corporation - Detroit MI
International Classification:

B29C 4302
US Classification:

156245
Abstract:

A composite leaf spring for a motor vehicle has an elongated body of layers of epoxy coated fibers extending in the longitudinal direction of the spring. The composite fiber/adhesive body is formed and cured to provide sufficient strength and flexibility to suspend the vehicle. A synthetic fiber pad is fixed adjacent the end of the spring for engagement with the spring hanger of the suspension system to resist wear of the body at the interface with the hanger. In the preferred embodiment, the pad is a woven fabric of aramid fibers at least some of which extend substantially normal to the wear interface. A specific double plane weave fabric including a warp/fill fiber ratio of approximately 7:1 provides superior results. Epoxy resin is preferred for the adhesive both for the body of the spring and for pre-impregnation of the pad. In the related method, the pre-impregnated pad is applied to the mold contoured to correspond to the shape of the spring and elongated fibers are layered in the mold over the pad.
