  • Patent number: 10221914
    Abstract: A vehicle suspension damper for providing a variable damping rate. The vehicle suspension damper comprises a first damping mechanism having a variable first threshold pressure, a second damping mechanism having a second threshold pressure, and a compressible chamber in communication with a damping fluid chamber, wherein the second damping mechanism is responsive to a compression of said compressible chamber.

  • Patent number: 10202166
    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.

  • Patent number: 10195919
    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.

  • Patent number: 10160511
    Abstract: A vehicle suspension damper is described. The vehicle suspension damper includes a primary valve and a pilot valve assembly. The pilot valve assembly includes an adjustable pilot spool configured for controlling a pressure inside the primary valve. The vehicle suspension damper further includes an externally-adjustable adjuster, wherein the pilot valve assembly meters fluid to the primary valve, and movement of the externally-adjustable adjuster varies an effective orifice size of the adjustable pilot spool. The vehicle suspension damper further includes a set of shims coupled to the primary valve, wherein a position of the adjustable pilot spool corresponds to an increase of pressure inside the primary valve and an increase of an axial force on the set of shims by said primary valve.

  • Publication number: 20180328442
    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.
