Embodiment Construction

[0020] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0021] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. figure 1 A vehicle comprising a suspension system having shock absorbers each comprising a piston assembly according to the invention is shown in , generally indicated by reference numeral 10 . The vehicle 10 includes a rear suspension 12 , a front suspension 14 and a body 16 . The rear suspension 12 has a laterally extending rear axle assembly (not shown) adapted to operatively support a pair of rear wheels 18 . The rear axle is attached to the body 16 by means of a pair of shock absorbers 20 and a pair of springs 22 . Similarly, the front suspension 14 includes a transversely extending front axle assembly (not shown) for operatively supporting a pair of front wheels 24 . The front axle assembly is attached to the body 16 by a pair of shock ...

Abstract

A shock absorber includes a valve assembly including a valve disc engaging inner and outer lands defined by a valve body. The inner land is a non-circular land such that a radial dimension between the inner land and the outer land varies based on a circumferential position of the radial dimension. The varying radial dimension provides progressive valve opening for the valve assembly.

Description

technical field [0001] The present disclosure relates generally to hydraulic dampers or shock absorbers for use in suspension systems, such as suspension systems for motor vehicles. More specifically, the present disclosure relates to a valve assembly having an eccentric pressure area on a valve disc for controlling opening of the valve assembly. 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 the car's suspension system to absorb unwanted vibrations generated during driving. To absorb this unwanted vibration, shock absorbers are usually attached between the sprung part (body) and the unsprung part (suspension) of a car. The piston is located in the pressure cylinder of the shock absorber, which is connected to the unsprung part of the car. The piston is connected to the sprung portion of the car by a piston rod that extend...
