Methods and apparatus for suspension adjustment

摘要

A shock absorber includes a gas spring cylinder containing a piston moveable between an extended position and a compressed position within the gas spring cylinder. A mechanical actuator is arranged whereby a bleed port is automatically closed when the gas spring is compressed to a predetermined position corresponding to a desired sag setting. In one embodiment, the position corresponds to a predetermined sag setting whereby the gas spring is partially compressed. In another embodiment, a proper sag setting is determined through the use of a processor and sensor that in one instance measure a position of shock absorber components to dictate a proper sag setting and in another instance calculate a pressure corresponding to a preferred sag setting.

主权项

1. A system for a vehicle, comprising:
a gas spring including a cylinder containing a piston, the piston being moveable between an extended position and a compressed position within the gas spring cylinder; a sensor operable to measure an operational characteristic of the gas spring, wherein said operational characteristic comprises:
a pressure Psag of the gas spring at a point of pressure equilibrium; and a computer processor in communication with the sensor, wherein the computer processor includes instructions that cause the computer processor to recommend an operational setting of the gas spring in response to an input from the sensor corresponding to the operational characteristic, wherein said operation setting that is recommended comprises: a preferred initial pressure using the formula: Pi=Psag×(1−sag fraction).
