Abstract
A spring for a suspension is described. The spring includes: a spring chamber divided into at least a primary portion and a secondary portion, and a fluid flow path coupled with and between the primary portion and the secondary portion. The fluid flow path includes a bypass mechanism, wherein the bypass mechanism is configured for automatically providing resistance within the fluid flow path in response to a compressed condition of the suspension.
Claims20
A component for a vehicle suspension, said component comprising:
- an upper leg tube;
- a lower leg tube telescopically coupled to said upper leg tube;
- a spring disposed in at least one of said upper leg tube and said lower leg tube and configured to provide a spring force which resists telescopic compression of said upper leg tube and said lower leg tube;
- and
- a gas spring disposed in at least one of said upper leg tube and said lower leg tube, said gas spring comprising:
- a first portion;
- a second portion;
- and
- a gas flow by-pass coupled to said first portion and said second portion, said gas flow by-pass comprising:
- an open position wherein gas flow between said first portion and said second portion is allowed and a first gas spring force resisting movement of said upper leg tube and said lower leg tube with respect to each other is provided, said gas flow by-pass having said open position when said upper leg tube and said lower leg tube are telescopically compressed, with respect to each other, to a first position;
- and
- a closed position wherein gas flow between said first portion and said second portion is substantially denied and a second gas spring force resisting movement of said upper leg tube and said lower leg tube with respect to each other is provided, said second gas spring force greater than said first gas spring force, said gas flow by-pass having said closed position when said upper leg tube and said lower leg tube are telescopically compressed, with respect to each other, to a second position, said second position comprising a greater amount of telescopic compression between said upper leg tube and said lower leg tube than occurs at said first position.
