  • Publication number: 20110248434
    Abstract: A gas spring capable of having long and short travel modes is described. The gas spring uses liquid in combination with pressurized air to affect the travel length. Unlike conventional gas springs, the gas spring according to the invention may have its travel reduced more than, for example, by 50%.

  • Publication number: 20110204549
    Abstract: A gas spring curve control valve for a adjustable-volume gas-pressurized device is described. The valve allows for selection from among at least four spring curves and can be packaged in small spaces/devices. In an exemplary embodiment of the invention, a rotary cam having grooves and lobes that interact with spring loaded ball bearings and an external adjuster knob are used to easily change the gas spring curve “on-the-fly” and with minimal user effort.

  • Publication number: 20110202236
    Abstract: Methods and apparatus of a system for vehicles comprising a vehicle suspension, a sensor operable to measure an operational characteristic of the vehicle suspension, and a processor in communication with the sensor that is operable to suggest an operational setting of the vehicle suspension in response to an input from the sensor corresponding to the operational characteristic. A method for adjusting a suspension of a vehicle may comprise receiving suspension data with a processor, calculating a suspension setting suggestion with the processor, communicating the suspension setting suggestion to a user interface device, and adjusting the suspension based on the suspension setting suggestion.

  • Publication number: 20100276906
    Abstract: A suspension system for a vehicle includes a damping assembly operatively connected to an actuator; a controller for controlling movement of said actuator whereby a damping rate of said damping assembly is adjusted by movement of the actuator; and a signal generating device remote from said damping assembly, which device, in use, provides an output electric signal representing a desired user adjustment to the damping rate of said damping assembly, said controller adapted to receive said electric signal and control said actuator to adjust said damping rate according to said electric signal, whereby said damping rate may be remotely altered during use of said vehicle.

  • Publication number: 20100263974
    Abstract: An integrated and self-contained suspension assembly having a gas spring integrated with a shock absorber (damper) is described. The rigid gas cylinder of the air spring is divided into a first gas chamber and a second gas chamber. A flow port connects the first and second gas chambers, and can be manually opened or closed by valve and a simple one-quarter turn rotation of an external knob to instantly switch the gas spring between two different spring rates. The different spring rates are functions of the separate or combined volumes of the two. gas chambers. The integrated suspension assembly is compactly packaged and self-contained, i.e., does not require any externalities, such as gas sources or electricity, to operate.

  • Publication number: 20100181709
    Abstract: Altering the damping rate of a vehicle suspension damper. A pressure of a damping fluid is exerted against a second valve mechanism connected to the vehicle suspension damper. The pressure of the damping fluid is increased beyond a threshold of the second valve mechanism that is adjustable by an adjustment member. The adjustment member is exposed through a high pressure side of the vehicle suspension damper. The second valve mechanism is then opened.
