  • Patent number: 10752070
    Abstract: A clamping plate is dimensioned to secure a flexible spring member to an end member for forming a gas spring assembly. The clamping plate includes a clamping plate wall with an axis and opposing surface portions oriented transverse to the axis. An opening extends into the clamping plate wall from along each of the opposing surface portions. An elongated damping passage extends in a spiral configuration through the clamping plate wall in fluid communication with the openings. A gas spring assembly includes a flexible spring member that defines a spring chamber, and an end member with an end member wall that defines an end member chamber. The clamping plate is secured to the end member and retains the flexible spring member thereon. The elongated damping passage is in fluid communication between the spring chamber and the end member chamber. Gas transfer between the spring chamber and the end member chamber generates pressurized gas damping during use of the gas spring assembly.

  • Patent number: 10744837
    Abstract: An end member assembly includes first and second end member sections. The first end member section includes a first securement feature integrally formed thereon. The second end member section includes a second securement feature integrally formed therein that is dimensioned to cooperatively engage the first securement feature. In an assembled condition, the first and second end member sections are operatively engaged to substantially inhibit axial displacement therebetween. A substantially fluid-tight joint can be formed between the first and second end member sections such that an end member chamber can be formed within the end member assembly. A third end member section can be included, and can be operatively connected to the second end member section. A gas spring assembly and a suspension system are also included.

  • Publication number: 20200256418
    Abstract: An inertia-actuated valve assembly includes a valve housing, a valve body and a biasing element. The valve housing includes a groove that has an open end fluidically accessible from along one side thereof. The valve housing includes a flow channel extending therethrough in fluid communication with the groove from along an opposing side of the valve housing. The valve body is positioned within the groove of the valve housing such that the valve body and the valve housing are axially co-extensive along at least a portion thereof. The biasing element operatively engages the valve body and generates a biasing force urging the valve body in a first axial direction. The biasing force is greater than a predetermined dynamic gas pressure threshold value multiplied by a pressure area and is less than or approximately equal to a valve body mass multiplied by 2.5 times the nominal acceleration due to gravity.

  • Publication number: 20200049228
    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.

  • Patent number: 10295009
    Abstract: A mounting assembly (200) includes first and second mounting components (108, 112) that are displaceable relative to one another. At least one positive-stiffness biasing element (236) exhibiting a positive-stiffness spring rate is operatively disposed between the first and second mounting components. At least one negative-stiffness biasing (288, 290) element exhibiting a negative-stiffness spring rate is disposed between the first and second mounting components in parallel with the at least one positive-stiffness biasing element. A combined spring rate of the at least one positive-stiffness biasing element and the at least one negative-stiffness biasing element is less than the positive-stiffness spring rate of the at least one positive-stiffness biasing element alone. The mounting assembly can exhibit a natural frequency that is less than a natural frequency of a mounting assembly having the at least one positive-stiffness biasing element without the at least one negative-stiffness biasing element.

  • Patent number: 10161471
    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.
