Abstract
A shock assembly with automatically adjustable ride height. The shock assembly includes a main chamber with a working fluid therein. A damping piston coupled to a piston shaft, the damping piston disposed in the main chamber to divide the main chamber into a compression side fluid chamber and a rebound side fluid chamber. An automatic ride height adjustment assembly including an internal floating piston (IFP) pump assembly and a spring preload piston assembly.
Claims15
A shock assembly comprising:
- a main chamber comprising a working fluid therein;
- a damping piston coupled to a piston shaft, said damping piston disposed in said main chamber to divide said main chamber into a compression side fluid chamber and a rebound side fluid chamber;
- an automatic ride height adjustment assembly comprising:
- a pump;
- a fluid reservoir fluidically coupled with said pump;
- and
- a fluid pathway configured to allow said working fluid to be pumped, by said pump, from said fluid reservoir, and along said fluid pathway to adjust a ride height of said shock assembly;
- wherein said pump comprises:
- a pump body;
- and
- a pump chamber to receive said working fluid from said fluid reservoir, said pump chamber configured to pump said working fluid through said fluid pathway to adjust said ride height of said shock assembly, said pump including a post adjustably coupled with said pump body to adjustably change a length of said post which extends from said pump body toward a component of said shock assembly, wherein a distance from an end of said post to said component establishes said ride height of said shock assembly, and wherein said distance from said end of said post to said component can be adjusted to modify said ride height of said shock assembly.

A pump assembly for adjusting a ride height of a shock assembly, said pump assembly comprising:
- a pump;
- a fluid reservoir fluidically coupled with said pump;
- and
- a fluid pathway configured to allow working fluid to flow, to or from said fluid reservoir, along said fluid pathway;
- wherein said pump further comprises:
- a pump body;
- and
- a pump chamber to receive said working fluid from said fluid reservoir, said pump chamber configured to pump said working fluid through said fluid pathway to adjust said ride height of said shock assembly, said pump including a post adjustably coupled with said pump body to adjustably change a length of said post which extends from said pump body toward a component of said shock assembly, wherein a distance from an end of said post to said component establishes said ride height of said shock assembly, and wherein said distance from said end of said post to said component can be adjusted to modify said ride height of said shock assembly.
