  • Publication number: 20210252935
    Abstract: Presented herein, inter alia, are suspension system components having tuned accumulator sizing and/or stiffness. Such suspension system components are envisioned for use in a distributed active suspension system of a vehicle. In particular, through appropriate sizing of accumulators of a suspension system component of a vehicle, ride quality of the vehicle may be improved and so called “rough ride” issues may be precluded. Alternatively or additionally, various valves or alternative compliant mechanisms may be included in the suspension system component, so that desirable performance may be obtained for a range of operating conditions.

  • Publication number: 20210231133
    Abstract: Disclosed herein are hydraulic actuators and methods for the operation of actuators having variable relative pressure ratios. Further disclosed are methods for designing and/or operating a hydraulic actuator such that the actuator exhibits a variable relative pressure ratio. In certain embodiments, the relative pressure ratio of the hydraulic actuator may be dependent on one or more characteristics (such as, for example, frequency or rate of change) of an oscillating input to the hydraulic actuator.

  • Publication number: 20200049266
    Abstract: Disclosed herein are various embodiments of a hydraulic actuator that includes one or more check valves having a dynamically varying cracking pressure. In certain embodiments, a hydraulic actuator may be configured to vary the cracking pressure of a check valve based on an operating condition of a pump of the hydraulic actuator. The check valve may be located along a bypass path in the hydraulic actuator, thereby allowing for fluid flow to bypass a pump of the hydraulic actuator by passing through the check valve. The use of such hydraulic actuators is contemplated in, for example, an active suspension system of a vehicle. Additionally, various embodiments of suitable check valves are disclosed. Additionally, methods are disclosed for operation of the check valve and the hydraulic actuator.

  • Publication number: 20200039316
    Abstract: In one embodiment, certain aspects of forces at a structural interface applied by one actuator are mitigated by a secondary actuator that applies a secondary force. In some embodiments the secondary actuator applies a static force. In yet another embodiment, an actuator is used to apply a force on a wheel assembly of a vehicle to detect and/or ameliorate the effect of certain tire incongruities.

  • Publication number: 20190105957
    Abstract: A pressurized top mount assembly is described wherein a pressurized fluid volume receives an end of a piston rod and is configured to counteract a net static force on a top mount by a suspension component which may be an active suspension actuator, a passive suspension damper or a semi active suspension damper. The pressurized fluid volume may be in fluid communication with one or more of fluid volumes in the suspension component.

  • Patent number: 10219919
    Abstract: The present invention provides a prosthetic hand capable of multiple grasp types. The prosthetic finger units are underactuated both within and between the finger units using a differential mechanism arrangement. The locking movement of the prosthetic thumb unit is coupled to the differential mechanism. As the user repositions the prosthetic thumb unit, the differential mechanism is effected as to alter both the initial positions and force distribution of the prosthetic finger units. The present invention further provides an additive manufacturing molding method for making the same.
