  • Patent number: 9764614
    Abstract: A suspension actuation assembly can include first and second support assemblies that are displaceable relative to one another in a first direction of travel. A connector assembly can extend between and operatively connect the first and second support assemblies. An actuator assembly can be displaceable between collapsed and extended conditions. The actuator assembly can be oriented transverse to the first direction of travel and can be operatively associated with the connector element such that displacement of the actuator assembly generates displacement of the first and second support assemblies relative to one another along the first direction of travel. A suspension system including such a suspension actuation assembly is also included.

  • Publication number: 20170211649
    Abstract: Suspension systems include a gas spring and gas damper assembly that is adapted for operation in first and second conditions. In the first condition, the assembly provides spring and damping functionality across a first range of travel. In the second condition, the assembly provides actuator functionality with a second range of travel that is substantially less than the first range of travel. A pressurized gas system is in fluid communication with the assembly. A control system is in communication with the assembly and the pressurized gas system. The control system is operative to actuate one or more control devices to transfer pressurized gas and thereby transition the assembly from between the first and second conditions. Methods of operating such as suspension system are also included.

  • Patent number: 9701170
    Abstract: A damper rod bushing operatively connects an end member of a gas spring and a damper rod of a damper to at least partially form a gas spring and damper assembly. The damper rod bushing is constructed for exposure to gas pressure within a spring chamber of a gas spring and damper assembly such that pre-load forces due to gas pressure within said spring chamber act on said damper rod bushing. The damper rod bushing can include an outer support element, an inner support element and an elastomeric connector element operatively connected between the outer and inner support elements such that a substantially fluid-tight seal is formed therebetween. A gas spring and damper assembly including such a damper rod bushing, as well as a suspension system including one or more of such gas spring and damper assemblies and a method of assembly are also included.

  • Publication number: 20160369867
    Abstract: Vibration isolators can be dimensioned for securement between a rotational motion source and a rotational motion target. The vibration isolators can include a first end member and a second end member supported in substantially-fixed axial position but axially-rotatable relative to the first end member. An intermediate member can be disposed between and operatively engaging the first and second end members. A rotational motion-to-axial motion conversion system is operatively disposed between the intermediate member and the first end member such that rotation of the intermediate member and the second end member generates axial displacement of the intermediate member relative to the first and second end members. A biasing element can be operatively disposed between the intermediate member and one or more of the first and second end members to bias the intermediate member in an axial direction. Rotary power transmissions or system are also included.
