Embodiment Construction

[0033] now refer to Figure 1 to Figure 7 , a composite leaf spring embodying the principles of the present invention is illustrated therein and generally designated 20 . The composite leaf spring 20 generally includes a central section 22 having a pair of opposite ends, and an optional pair of end sections 24 integrally formed with the opposite ends of the central section 22 to define a single piece. formula structure. The end sections 24 each also include a cylindrical inner liner, such as a bushing 26 , that defines an opening 28 extending transversely through the end sections 24 . The opening 28 is arranged to receive an attachment member (not shown) allowing the leaf spring 20 to be attached to the vehicle using conventional means known to those skilled in the art. Bushing 26 may be formed from a variety of materials including, but not limited to, metal and plastic. Although shown and described herein in principle as including an integrally formed end section 24 , it s...

Abstract

A composite leaf spring having a central section with opposed ends, and optionally end sections connected thereto, and including a fiber reinforced body composed of a fiber reinforcement embedded within a cured resin. The fiber reinforcement is formed from layers of a web having strands extending longitudinally in the direction of the length of the leaf spring and further having a plurality of transverse elements extending transversely relative to that length. The fiber reinforcement is impregnated with the resin upon molding.

Description

technical field [0001] The present invention relates generally to vehicle suspension systems. More specifically, the present invention relates to composite leaf springs for use in vehicle suspension systems. Background technique [0002] Springs, and especially coil and leaf springs are often used to form part of a vehicle suspension system. The suspension system supports the vehicle's running gear (eg, wheels, axles, and portions of the driveline) from the vehicle's frame. By suspending the vehicle's running gear, stability is provided to the vehicle when it is subjected to operating forces that occur during the vehicle's motion. As used herein, the term vehicle is intended to include passenger cars, non-passenger cars, light duty trucks (such as pickups), medium and heavy duty trucks, special or utility vehicles (such as vans and Trailers, rail vehicles, including railcars. [0003] Historically, leaf springs such as those found in the front or rear suspensions of pass...
