  • Publication number: 20150053496
    Abstract: A powertrain mounting system for a vehicle powertrain includes a first powertrain mount that exhibits a first gradual rate of change of static stiffness when under load. The mounting system also includes a second powertrain mount that exhibits a second gradual rate of change of static stiffness when under load. The first gradual rate of change of static stiffness is related to the second gradual rate of change of static stiffness by a static equilibrium torque balance equation of respective displacements at the first and the second powertrain mounts. The static equilibrium torque balance equation is based in part on a spatial arrangement of the first and the second powertrain mounts relative to the powertrain. A method of designing the powertrain mounting system determines the first and second gradual rates of change of static stiffness under load to achieve efficient energy management.

  • Patent number: 7918432
    Abstract: This invention relates to a support or hanger utilizing a conical spring washer or set of conical spring washer displaying variable load characteristics. When installed, both types (support or hanger) allow for small movements in pipe, ductwork or equipment (PDE), thus, allowing for the thermal growth of PDE. Conventionally, helical coil spring supports are chosen to meet the load capacities of PDE but are reluctantly used because of their large size. By using conical spring washer s, the size of the support is substantially reduced making it a more useable device. A smaller, more compact design proves to increase the support/hanger's application making it more stable to place under piping and even under reciprocating motion equipment like generators and pumps. For small displacements, it is found that this invention behaves in the same manor as a conventional helical coil spring support under the same applied loads.

    Abstract: An air ride system is provided for tractors and other agricultural vehicles to provide a smooth operator ride. The system includes a bracket mounted to the transmission housing beneath the cab. A pair of shock absorbers and a pair of air bags extend between the bracket and the cab so as to absorb forces generated during travel of the vehicle over the ground. A laterally extending control rod provides anti-sway for the cab. Stop members limit the upward and downward travel of the cab relative to the transmission housing. A compressor and air lines allow air to be supplied to or removed from the air bags to adjust the ride.

    Abstract: A bracket assembly for a car shaker vibrator that includes a vibrator mounting member that is pivotally connected by a pivot pin, in a hinged or clevis arrangement, to a wedge member. The wedge member includes the male portion of a Gardner type bracket that is adapted for engaging a mating female portion that is mounted on a railroad car. The vibrator mounting member may be selectively rotated between a first position and a second position. The vibrator mounting member is retained at the first position by a locating pin during the emptying of a railroad car during the selective operation of the car shaker vibrator. The vibrator mounting member is retained at the second position by the locating pin when the dislodgement of the male portion from the female portion is desired together with the selective and subsequent operation the car shaker vibrator. An intermediate position may be provided between the first position and the second position and used when needed.

  • Patent number: 6739568
    Abstract: An apparatus for isolating and leveling a machine foundation with respect to a substructure of a building or the ground. The apparatus of the present invention provides an enclosure connectable to the machine foundation. A load bearing member is disposed within and adjustably connected to the enclosure. A resilient member is positioned between and in contact with the bearing member and the substructure for supporting and isolating the machine foundation from the substructure and providing a leveling mechanism to level the machine foundation. At least one gauge extends between the bearing member and the substructure to determine the distance between the bearing member and the substructure so that the machine foundation may be leveled. Additional stabilizers are provided with an anchor plate assembly adjustably connected to the enclosure. The stabilizers include an isolating member biased against a sidewall of the substructure by the anchor plate assembly to provide added stability to the machine foundation.

  • Patent number: 6676101
    Abstract: A horizontal-motion vibration isolation system for supporting an object in an equilibrium position relative to a base while suppressing the transmission of horizontal vibratory motion between the object and the base includes a plurality of columns, each column having a rigid member with a first end and a second end. A tilt mechanism is operatively connected to each first end of the rigid members and the object. Likewise, a tilt mechanism is operatively connected to each second end of the rigid members and the base. Each tilt mechanism exhibits a tilt rotational stiffness and the horizontal translation of the object relative to the base causes tilt rotation of the columns. The tilt rotational stiffness of the tilt mechanisms is approximately proportional to the compression load transmitted to the columns by the weight of the object, so that the horizontal natural frequency of the system is nearly insensitive to the payload weight.

  • Patent number: 6623318
    Abstract: Torque roll, such as in a marine propulsion unit for driving a propeller, is significantly reduced or substantially eliminated by utilizing inflatable elements, such as airbags. One or more airbags engage the top of a propulsion unit mounting surface supported by an elastomeric isolation mount where a torque roll force is substantially upward, and one or more other airbags engage the bottom of a mount for the propulsion unit at a location where the torque roll force is substantially downward. The amount of gas supplied to the airbags is preferably substantially proportional to the torque roll force at each of the airbags. By significantly reducing or substantially eliminating the torque roll of the propulsion unit, the unit can be connected to other components without line shaft couplings.
