  • Patent number: 8267821
    Abstract: A mechanical tensioner that includes a pulley arm with a tension pulley for a tension element drive of an internal combustion engine. The pulley arm is mounted to a mounting base that is fixedly attached to the engine. A spring that functions in compression and torsion is located about a pivot axis on the mounting base, with one end connected to the pulley arm and the other end attached to the mounting base. The spring provides torsion to the pulley arm to maintain tension on the tension element, and is also compressed between a mounting flange of the pulley arm and a support flange on the mounting base to transmit an axial force between the pulley arm and an outer hub that is fixed to the mounting base. A shaped bush which functions at least as a damping element, and can also function as a bearing, is located in the space between the outer hub and the pulley arm.

  • Patent number: 8181763
    Abstract: A window winder drive functions with a freewheeling coupling, which has an outer coupling part and an inner coupling part, which is concentric thereto, and comprises clamping bodies arranged between a clamping face of the outer coupling part and a clamping face of the inner coupling part, wherein the clamping bodies are arranged in pairs in the annular space formed between the clamping faces, and the first clamping body of a pair of clamping bodies demonstrates a clamping effect exclusively in a specific direction of rotation of the outer coupling part in relation to the inner coupling part, while the second clamping body of the pair of clamping bodies exclusively has a clamping effect in the opposite direction of rotation.

  • Patent number: 8127910
    Abstract: A frictional engagement assembly for an automotive device, including: at least one frictionally engageable plate; a first piston plate displaceable in a first axial direction to urge the at least one frictionally engageable plate into frictional contact; a first resilient element engaged with the first piston plate and urging the first piston plate in a second axial direction substantially opposite the first axial direction; a check valve controlling fluid flow to displace the first piston plate; and an accumulator. As fluid from a chamber, at least partially formed by the first piston plate, discharges through the check valve, the accumulator controls fluid volume in the chamber to maintain a distal portion of the first piston plate, urging the at least one frictionally engageable plate into frictional contact, in a furthest position in the first axial direction.

  • Patent number: 7779804
    Abstract: A rocker arm assembly for a valve train of an internal combustion engine which has a rocker arm that pivots on a support pin about an axis where a push rod contacts one end of the assembly and a valve shaft of a gas exchange valve contacts the other end of the assembly. A rocker arm is mounted on a support pin through a radial roller bearing for handling radial forces. An outer bearing support wall is attached to the rocker am and covers both ends of the support pin. Between the ends of the support pin and the outer bearing wall is a thrust washer for handling axial forces in the rocker arm assembly. The radial bearing assembly can have an outer bearing shell and an inner bearing shell where the outer bearing shell has a generally U-shaped configuration that covers the end wall of the support pin. The bottom wall of the outer bearing shell forms the outer bearing support wall for the thrust washer.

  • Patent number: 7661883
    Abstract: A sealing element for rotatable parts is provided by the invention. To achieve low and uniform wear, automatic reshaping of the sealing surfaces for advancing wear, low friction forces, and long service life, the sealing element has sealing surfaces (4) and sealing counter surfaces (5), whose sealing effect is provided by the interaction of a sealing element (3, 11) constructed as a tractrix body with a correspondingly shaped sealing counter element (6, 13, 14).
