The upper cushioning member includes a non-circular extension corresponding to the shape of the aperture in the vehicle frame whereby relative rotation between the upper cushioning member and the vehicle frame is prevented.Type: GrantFiled: January 21, 1992Date of Patent: December 15, 1992Assignee: Cooper Tire & Rubber CompanyInventors: Kenneth E. Killworth, Thomas A. Knurek, Robert A. Pritchett

Patent number: 5170984Abstract: The invention concerns a holding element 1 made of plastic and having at least one storage or gripping zone 5 designed for receiving and holding at least one tube-shaped part adjacent to a mounting zone 7. The holding element 1 is characterized by a three-component design which includes a first component 2 made of a hard plastic material and carrying the storage or gripping zone 5. A second component 3 formed of a soft plastic vibration damping material is positioned in component 2 and receives a third component 4 formed of hard material which is positioned in component 3 via a transverse aperture 6. Component 3 carries the mounting zone 7 which provides the ability to connect the holding element to an associated support structure.Type: GrantFiled: October 25, 1991Date of Patent: December 15, 1992Assignee: TRW United Carr GmbH & Co., K.G.Inventor: Hans-Werner Ruckwardt

Patent number: 5158269Abstract: A shock absorber mount is described as having two pressed fittings which are mounted in end-to-end relationship. Each insert has two rigid, radially spaced cylindrical sleeves which are separated by a resilient rubber insert. The inner sleeve of the vertically lowermost fitting, when the fittings are properly mounted on, for example, an automobile frame, extends upwardly beyond the associated outer sleeve and is coated with rubber to enter a hollow bore formed by the inner sleeve of the upper fitting. The extension allows the lower fitting to initially absorb an upwardly applied axial force until it moves into shock absorbing relation with the upper fitting. The extension also acts to bolster the radial shock absorbing characteristics of the upper fitting to provide improved shock absorbing characteristics of the mount; namely, low axial shock absorption and high radial shock absorption.Type: GrantFiled: October 11, 1990Date of Patent: October 27, 1992Assignee: GenCorp Inc.Inventors: Richard D. Hein, Bradley G. Hampton, Tony R. Jones, James R. Goewey

Patent number: 5154403Abstract: A U-shaped bracket supports an elastomeric bush type vibration damping mount on a power unit (ICE plus transmission). The inner tubular member of the damper is mounted on the arms of the bracket by way of a bolt. First and second tubular piezoelectric/electrostrictive strain generating elements are symmetrically disposed about the bolt and housed within the inner tubular member of the mount. A control unit which is responsive to crank angle and engine speed, produces a AC current and applies the same to the first strain generating element. The phase of the same current is shifted by 90.degree. before being applied to the second strain generating element.Type: GrantFiled: December 20, 1990Date of Patent: October 13, 1992Assignee: Nissan Motor Co., Ltd.Inventor: Shigeki Sato

Patent number: 5145143Abstract: An apparatus for use in a vibration damping assembly includes a bushing that is die formed from a steel blank. The bushing is formed to have a substantially tubular shape with an interior surface defining an inner cavity into which moving rods can be inserted, an exterior surface, and a joint having a first edge in overlapping contact with a second edge to form a contact surface. The joint formed by the contact surface between the first and second edges extends between the exterior surface and the interior surface of the bushing.Type: GrantFiled: September 10, 1990Date of Patent: September 8, 1992Assignee: Steel Parts CorporationInventors: Arthur C. Jackson, Raymond P. Chandler

Patent number: 5145330Abstract: An automotive refrigerant compressor according to the present invention comprises a compressor housing that includes at least one bracket. The bracket has a hole through which a fastening member, such as a bolt for example, penetrates. A bushing, which includes a flange portion formed at one end, is inserted into the hole in the bracket with the flange portion disposed at an outer surface of the bracket. A washer-like vibroisolating member is fixed to the flange portion of the bushing by a cyanoacrylate adhesive. In accordance with this construction, the refrigerant compressor can be easily mounted within the engine compartment of a motor vehicle without having to be concerned with the conventional problem of slipping vibroisolating members.Type: GrantFiled: September 24, 1991Date of Patent: September 8, 1992Assignee: Sanden CorporationInventor: Yuji Uchiyama

Patent number: 5141203Abstract: A snubber arrangement which connects to a composite hollow beam structure without requiring the penetration of the composite material. The snubber includes an attachment assembly having first and second metallic outer layer bonded to an inner layer of composite material, with one of the outer layers being in intimate bonded contact with a surface of the composite hollow beam. A threaded insert in the attachment assembly receives a bolt around which a multipart spool is located. The hollow beam is mounted on a support structure and the spool has upper and lower flange portions which are located on either side of an aperture within the support structure such that the spool is maintained in position to limit excessive movement of the composite structure to which the snubber is attached.Type: GrantFiled: February 21, 1991Date of Patent: August 25, 1992Assignee: Westinghouse Electric Corp.Inventors: Jennifer A. Baker, Alvin H. Nakagawa, Christy L. Kirchner

Patent number: 5127698Abstract: An axially loadable support bearing for the elastic connection of vehicle parts has a rubber bush equipped with a metal bearing core and a sheet-metal casing provided with a flange. In the installation position of the support bearing, the flange is supported on one edge of a receiving lug receiving the bearing. The bead-like bush endpiece facing away from the flange engages behind the other edge of the receiving lug and has supporting elements which engage in a snap-like manner behind the edge of the receiving lug. An abutment is assigned in the bush endpiece at an axial distance from the edge of the receiving lug. A reliable bearing support in the receiving lug in each axial direction is achieved respectively by the flange and supporting elements.Type: GrantFiled: March 25, 1991Date of Patent: July 7, 1992Assignee: Mercedes-Benz AGInventor: Werner Konig
