Abstract
A vehicle suspension system includes a suspension arm connected to a vehicle frame or body. A wheel is supported by the suspension arm and a shock absorber is connected between the vehicle frame or body and the suspension arm. The shock absorber includes a first mounting fitting having a first connecting structure, a second mounting fitting having a second connecting structure and a monolithic elastomeric body molded around the first connecting structure and the second connecting structure.
Claims15
A shock absorber comprising:
- a monolithic elastomeric body comprising a first end and a second end, wherein the first end is located near a vehicle chassis and the second end is located near a wheel, wherein the monolithic elastomeric body includes a variable distribution of at least one of:
- ribs, apertures, materials along a length of the monolithic elastomeric body to transfer loads and provide a variable dampening and a variable stiffness from the first end to the second end,
- wherein the monolithic elastomeric body includes a plurality of apertures disposed proximate the second end.
A vehicle suspension system comprising:
- a suspension arm connected to a vehicle frame or body;
- a wheel supported by the suspension arm;
- a shock absorber connected between the vehicle frame or body and the suspension arm, the shock absorber including:
- a first mounting fitting proximate the wheel and having a first connecting structure;
- a second mounting fitting proximate the vehicle frame and having a second connecting structure;
- and
- a monolithic elastomeric body secured to the first connecting structure and the second connecting structure, wherein the monolithic elastomeric body includes a variable distribution of at least one of:
- ribs, apertures, materials along a length of the monolithic elastomeric body to provide a predefined stiffness and dampening characteristics, wherein the monolithic elastomeric body has a lower stiffness near the second connecting structure and a higher dampening constant near the first connecting structure,
- wherein the monolithic elastomeric body includes a plurality of apertures disposed proximate the second connecting structure.
6 more elements
A shock absorber comprising:
- a monolithic elastomeric body having a first end proximate to a vehicle frame and a second end proximate to a wheel, wherein the monolithic elastomeric body includes a variable distribution of a combination of:
- ribs, apertures, materials along a length of the monolithic elastomeric body, wherein the first end is configured to absorb loads delivered to the wheel, and the second end is configured to provide dampening characteristics,
- wherein the first end comprises a plurality of apertures and the second end comprises a plurality of apertures.
