  • Patent number: 8376331
    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 include an optional integral elastomeric heat shield which protects the shear hub.

  • Patent number: 8366069
    Abstract: An isolator assembly includes an elastomeric assembly which is disposed within a socket defined by a supporting structure. The socket defines a transition portion, a retention rib and a stopping rib. The elastomeric assembly is positioned in the socket by sliding the elastomeric assembly through the transition portion so that the elastomeric assembly is compressed as it moves into the retention rib. The stopping rib engages an end surface of the elastomeric assembly once it has been properly positioned in the socket.

  • Patent number: 8296949
    Abstract: An apparatus for designing a tubing configuration comprising modules that receive tube design input, interpret a tube design input, calculate a final tube design, and display a final tube design. The tube design input may include point locations, bend criteria and end conditions, among others. The apparatus may further include modules that determine whether the tube design input exceeds a complexity threshold, comprises a minimum set of information, and comprises a conflicting or erroneous design. The apparatus may further include modules that determine and optimize the manufacturing cost as well as determine the manufacturability of the tube. The apparatus may further include modules that store operational challenges corresponding to emissions reduction features and secondary components.

  • Publication number: 20120207581
    Abstract: A truck body that efficiently hauls oil sands, which typically coagulate and adhere together in one consolidated mass. The adhesion of this consolidated mass to the surface of the truck body is minimized and the buildup of “carryback” is effectively prevented during haul cycles. Hauled amalgamated materials are dumped from the truck body such that the amalgamation breaks down and is safely dumped. One typical material that displays such a coagulated conglomerate massing is “oil sands” from which oil is extracted. A non-stick surface is provided on the truck body to overcome the natural adhesiveness displayed by this material and, when being dumped from a truck body, provides a means to assist in releasing the material from the truck body without leaving significant “carryback” that tends to buildup over haul cycles. Plus, the body design encourages the material to break down as it is dumped.

  • Patent number: 8151922
    Abstract: An exhaust apparatus includes an exhaust pipe passing under the front floor and rear floor and extending toward the rear of the vehicle. A noise eliminator is arranged under the rear floor and a fuel tank is arranged in a side portion in the vehicle width direction of the noise eliminator. A portion of the exhaust pipe on the front side of the front floor and a portion on the rear side of the noise eliminator are elastically mounted to the vehicle body. The exhaust pipe and a portion on the side opposite to the side of the fuel tank at a lower surface portion of the front floor are coupled by a metal wire having slack in an intermediate portion therebetween. In a side impact to the vehicle body, the fuel tank and noise eliminator do not interfere with each other.

  • 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.
