  • Patent number: 8152146
    Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member and an outer structural member. The elastomeric body includes a shear hub extending between radial flanges defined by the inner and outer structural members that undergoes shearing stresses during deflection of the elastomeric isolator. The inner and outer structural members are designed to provide a travel stop for the elastomeric isolator in order to avoid compression of the shear hub during high loads. The elastomeric bushing can also includes an optional integral elastomeric heat shield which protects the shear hub.

  • Publication number: 20120055746
    Abstract: A coulomb damper is attached to a component of an exhaust system. The inner surface of the coulomb damper is in intimate contact with the outer surface of the component of the exhaust system. The intimate contact is defined by a pair of weld lines extending along an axial length of the coulomb damper in one embodiment. In another embodiment, the intimate contact is defined by at least a three point contact between the coulomb damper and the component of the exhaust system. In another embodiment a coulomb damper includes an outer member press fit over an inner member. A chamber is defined between the inner and outer member. In one embodiment, the inner member and the outer member are coaxial and the chamber is an annular chamber having a constant radial width. In another embodiment, the chamber is eccentric in relation to the inner member and has a variable radial width.

  • Publication number: 20120031163
    Abstract: A testing machine tests the durability of backer pads on the track shoe assembly and the surface of the road wheel. The test machine utilizes two eccentric drives to move a section of a road wheel to simulate actual vehicle conditions. A positioning system positions the track shoe assembly with respect to the road wheel to adjust the loading between the two components.

  • Patent number: 8066266
    Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member and an outer structural member. The elastomeric body includes a shear hub extending between radial flanges or end plates of the inner and outer structural members that undergoes shearing stresses during deflection of the elastomeric isolator. The elastomeric body is bonded to the radial flanges or end plates. The inner structural member includes a radial flange which is axially offset from an axial flange of the outer structural member. The outer structural member includes a radial flange which is axially offset from an axial flange of the inner structural member. With this configuration, excessive stresses on the elastomeric body are avoided during high load movements of the elastomeric isolator.

  • Publication number: 20110116731
    Abstract: An elastomeric bushing includes an inner component, a pair of outer components and an elastomeric bushing disposed between the inner component and the pair of outer components. An annular gap is defined between the pair of outer components. When the elastomeric bushing is assembled into a housing, the width of the gap is reduced or eliminated increasing the compression of the elastomeric bushing.

  • Patent number: 7644911
    Abstract: An elastomeric isolator has an elastomeric body which defines a void extending into the elastomeric body from one side and a void extending into the elastomeric body from the opposite side. One member for attaching the elastomeric body to a component is located inside of the two voids and another member for attaching the elastomeric body to a component is located outside of the two voids. The two voids overlap a specified distance to determine the stresses and stiffness for the isolator.

  • Patent number: 7637486
    Abstract: A hydraulic mount has an upper support member and a lower support member. An upper elastomeric spring and a lower elastomeric spring are disposed between the upper support member and the lower support member to define an upper fluid chamber and a lower fluid chamber. A channel extends between the upper and lower chambers. During compression and extension of the hydraulic mount, fluid transfers between the upper and lower chamber to provide a damping force for the hydraulic mount.

  • Publication number: 20090315235
    Abstract: An elastomeric isolator has an elastomeric body which incorporates an inner structural member that extends through an outer structural member. The elastomeric body includes an axial shear leg extending between the inner and outer structural members that undergo shearing stresses during deflection of the elastomeric isolator. The inner structural member includes radial flanges which are axially offset from radial flanges of the outer structural member. The axial shear leg extends between the pair of radial flanges and is bonded to them at a position outside of the outer structural member. With this configuration compression of the shear hub during high loads is avoided.
