Embodiment Construction

[0021] The present disclosure will now be described more fully with reference to the accompanying drawings. Referring now to the drawings, in which like reference numerals designate like or corresponding parts throughout the views, figure 1 A vehicle 10 is shown incorporating a suspension system having a plurality of shock absorbers with variable radius spring disks in accordance with the present disclosure. The vehicle 10 includes a rear suspension 12 , a front suspension 14 and a body 16 . The rear suspension 12 has a transversely extending rear axle assembly (not shown) adapted to operatively support rear wheels 18 of the vehicle. The rear axle assembly is operatively connected to the vehicle body 16 by a pair of shock absorbers 20 and a pair of coil springs 22 . Similarly, the front suspension 14 includes a transversely extending front axle assembly (not shown) that operatively supports front wheels 24 of the vehicle. The front axle assembly is operatively connected to ...

Abstract

A shock absorber for a vehicle may include a piston and a valve disc assembly. The piston defines a plurality of passages extending through the piston between an upper working chamber and a lower working chamber of a fluid chamber. The valve disc assembly engages the piston and controls a flow of fluid between the upper working chamber and the lower working chamber through the plurality of passages. The valve disc assembly includes a variable radius spring disc among a plurality of discs. The variable radius spring disc has a varying outer radius. The valve disc assembly has a stiffness that varies circumferentially based on the variable radius spring disc such that an actuation of the valve disc assembly with respect to the piston varies circumferentially.

Description

technical field [0001] The present disclosure relates to shock absorbers. More specifically, the present disclosure relates to a valve disc assembly for controlling the damping characteristics of a shock absorber. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Shock absorbers are used in conjunction with a car's suspension system to absorb unwanted vibrations that occur during driving. In order to absorb unwanted vibrations, multiple shock absorbers are usually connected between the sprung part (body) and the unsprung part (suspension) of the car. The piston is located in the pressure tube of the shock absorber, and the pressure tube is connected to the unsprung part of the vehicle. The piston is connected to the sprung portion of the car by a piston rod that extends through the pressure tube. [0004] The piston divides the pressure tube into upper and lower workin...
