Problems solved by technology

[0006] However, a significant challenge when designing plastic or composite reinforced spring seat components is that spring seats made of plastic or composite materials typically have lower toughness
Thus, increasing the toughness of spring seat components, especially traps, without significantly increasing their weight or cost has proven to be a significant challenge

Embodiment Construction

[0021] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0022] refer to figure 1 , shows a strut type damper 10 according to an embodiment of the present disclosure. The damper 10 in this example includes a shock absorber 12 having a tubular body, an upper spring seat 14 , a coil spring 16 and a lower spring seat 18 . The mounting flange 20 enables the damper 10 to be fastened with its lower end to a wheel part of the vehicle, usually a steering knuckle. A telescoping piston rod (not shown) of shock absorber 12 is typically coupled to the body of the vehicle. The lower spring seat 18 is fixedly fastened to the outer surface of the shell 12a of the tubular shock absorber 12 .

[0023] see figure 2 , the lower spring seat 18 can be seen in more detail. Lower spri...

Abstract

A strut-type damper is disclosed. The damper has a shock absorber having a housing with a telescoping piston rod, a coil spring, an upper spring seat operably coupled to a distal end of the piston rod, and a lower spring seat operatively coupled to the housing. The upper and lower spring seats capture the coil spring therebetween. The lower spring seat has a base portion having an opening for receiving the housing and is fixedly securable to the housing. A generally circumferential wall portion extends from the base portion and forms a catcher for catching a broken portion of the coil spring if the coil spring fractures. An impact absorbing structure is formed on the lower spring seat adjacent both of the catcher and the base portion, and is configured to be crushed in the event of a fracture of the coil spring.

Description

technical field [0001] The present disclosure relates to a damper for a motor vehicle suspension system, and more particularly to a damper having a spring seat designed in such a way and made of a material that absorbs if the coil spring of the damper The energy generated by the break, and its operation to significantly reduce the chance of a broken coil spring contacting the wheels of the vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Strut-type suspension systems are well known in the motor vehicle industry. This telescopic suspension system is also commonly referred to as a McPherson shock absorber. A strut-type shock absorber assembly typically incorporates a hydraulic damper and is used as one of the positioning members for a wheel of a motor vehicle. Strut-type shock absorber assemblies typically include coil springs arranged conc...
