  • Patent number: 8974009
    Abstract: An axle for removably retaining a wheel on a vehicle. The axle comprises a rotary-type connector at a first end thereof; a cam assembly operatively connected to the second end, the cam assembly including a cam having an axis of rotation; a lever operatively connected to a second end of the axle, said lever being rotatable about an axis substantially parallel to the axis of rotation of the cam, between an open position in which the axle is removable from and mountable on the vehicle and a closed position in which the axle is retained on the vehicle; and a cam assembly operatively connected to the second end; and a lever stop ensuring that an angle of maximum rotation for the lever from the closed position is less than 180 degrees.

  • Patent number: 8925933
    Abstract: Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond.

  • Patent number: 7690432
    Abstract: Methods and apparatus for utilizing a downhole deployment valve (DDV) to isolate a pressure in a portion of a bore are disclosed. The DDV system can include fail safe features such as selectively extendable attenuation members for decreasing a falling object's impact, a normally open back-up valve member for actuation upon failure of a primary valve member, or a locking member to lock a valve member closed and enable disposal of a shock attenuating material on the valve member. Actuation of the DDV system can be electrically operated and can be self contained to operate automatically downhole without requiring control lines to the surface. Additionally, the actuation of the DDV can be based on a pressure supplied to an annulus.

  • Publication number: 20090236807
    Abstract: Embodiments of the invention generally relate to methods and apparatus for use in vehicle suspension. Particular embodiments of the invention relate to methods and apparatus useful for variable spring rate and/or variable damping rate vehicle suspension. In one embodiment, a shock absorber for a vehicle includes a gas spring having first and second gas chambers. The first chamber is utilized during a first travel portion of the shock absorber and the first and second chambers are both utilized during a second portion of travel. The shock absorber further includes a fluid isolated damper for regulating the speed of travel throughout both portions of travel.
