Embodiment Construction

[0023] The following description is merely exemplary in nature and is not intended to limit the disclosure, application, or use. figure 1 A vehicle is shown in which incorporates a suspension system with a shock absorber according to the invention and is generally designated by the reference number 10. The vehicle 10 has been depicted as a passenger car having a front axle assembly and a rear axle assembly. However, the shock absorber according to the present invention can be used with other types of vehicles or for other types of applications. Examples of these alternative arrangements include, but are not limited to, vehicles incorporating non-independent front suspension and / or non-independent rear suspension, incorporating independent front suspension and / or independent rear suspension or other suspensions known in the art System of vehicles. Additionally, the term "shock absorber" as used herein means a general damper and will therefore include McPherson spools and other ...

Abstract

A shock absorber has a housing with a piston rod assembly disposed therein. A first rod guide member is secured within a first portion of the housing so as to be concentrically disposed about at least a portion of the piston rod assembly. A second rod guide member is secured within the housing adjacent the first rod guide member so as to be concentrically disposed about at least another portion of the piston rod assembly. An electronically controlled valve assembly is disposed within the second rod guide member and is in communication with the first rod guide member.

Description

[0001] Cross references to related applications [0002] This application claims the priority of U.S. Patent Application Serial No. 13 / 947,169 filed on July 22, 2013 and also claims the rights of U.S. Provisional Patent Application No. 61 / 786,682 filed on March 15, 2013. The entire disclosures of the above applications are incorporated herein by reference. Technical field [0003] The present disclosure generally relates to a hydraulic damper or shock absorber used in a suspension system such as a suspension system used in a motor vehicle. More specifically, the present disclosure relates to an improved rod guide assembly for a shock absorber. Background technique [0004] This section provides background information related to this disclosure, not necessarily prior art. [0005] The shock absorber is used in conjunction with the car suspension system to absorb unwanted vibrations generated during driving. In order to absorb undesired vibrations, shock absorbers are usually connect...
