  • Patent number: 9381772
    Abstract: A rim onto which a vehicle tire is pulled or can be pulled. The rim has a rim base with at least one device to absorb sound in the manner of a Helmholtz resonator, an air volume partly ring-shaped and at least one opening into the tire interior. The air volume of the Helmholtz resonator is formed by the rim base, by wall and/or web elements, which are arranged on the rim base at a distance from one another when seen in the axial direction of the rim, which are radially oriented, and which are at least partly circumferential, and by a covering element or by a covering element and transverse walls, which delimit the air volume in the circumferential direction. The covering element may be connected to the wall and/or web elements in a form-fitting manner or in a form-fitting and force-fitting manner and in an airtight manner.

  • Publication number: 20140026694
    Abstract: Pressure piece (9) of a rack-and-pinion steering system, wherein the pressure piece (9) can be pressed along a pressure axis (D) against a rack (5), wherein the pressure piece (9) has a guide (14) for the rack (5) along its rack axis (Z), wherein an adjusting device (17) for adjusting the guide (14) of the pressure piece (9) along an adjusting axis (S) is provided, wherein the adjusting axis (S) intersects a plane containing the pressure axis (D) and also the rack axis (Z). It is possible to place the rack (5) off-axis in a targeted manner in order to reduce unwanted noise.

  • Patent number: 8057336
    Abstract: A guide device for an endless torque-transmitting member. The guide device includes at least two corresponding guide tongues between which the endless torque-transmitting member is at least partially guided. The guide tongues are held at a predetermined distance from each other by a connection region. The distance between the guide tongues is maintained substantially constant when there is a temperature change by the use in the guide device of materials having different coefficients of thermal expansion. A mold for producing a guide device is disclosed and includes two corresponding mold halves, where at least one connecting component formed from a material having a lower coefficient of thermal expansion than that of the guide tongues is held in one mold half.

  • Patent number: 7927020
    Abstract: A decoupling device for the bearing arrangement of a shaft carried in a housing, in particular a shaft of a belt-driven conical-pulley transmission with a chain that functions as the belt. The decoupling device includes an outer bearing ring configured with a circularly cylindrical outer surface and within which the shaft is mounted, and an inner surface of a housing that encloses the bearing ring outer surface. At least one radial ondular washer is arranged between the bearing ring outer surface and the housing inner surface, which allows a limited relative radial movement between the housing inner surface and the bearing ring outer surface by elastic deformation of the washer.

  • Publication number: 20070275803
    Abstract: A guiding and tensioning device for chain drives in vehicles is provided, having a guiding and tensioning element that can be fastened at a supporting part (4) of the vehicle and can be brought into an effective contact with the chain (1) of the chain drive. The device is provided as a rail (2) arranged in a plane of the chain drive and supported at the carrying part (4), which in order to reduce oscillations created by the chain drive can be acted on by at least one actuator with a force acting in the direction of the chain. In order to effectively and permanently suppress chain whining in such chain drives, the rail (2) is provided as a carrier supported on two supports. One support is formed by a drag bearing (3) arranged on the supporting part (4) in a locally fixed manner and the other support is a movable support (8) on the rail (2), which can be displaced in the longitudinal direction. At least one actuator (6a, 6b, 6c, 6d) is arranged between the supports and engages the rail (2).

  • Patent number: 7225699
    Abstract: A gear drive mechanism with two rotary gears meshing with each other has a first friction rim surface rotationally coupled to one of the two gears and a second friction rim surface rotationally coupled to the other of the two gears. The friction rim surfaces are in mutual contact with each other and thereby enabled to transmit a friction-based torque between each other.

  • Patent number: 7223020
    Abstract: A bearing assembly including a bearing having an outer bearing ring and an inner bearing ring. The outer bearing ring is axially received in a bearing-receiving recess that includes a substantially cylindrical inner wall. An element that is radially flexible is located between at least one of the outer bearing ring and the inner wall of the recess, and the inner bearing ring and a rotatable member that is rotatably carried in the bearing assembly. The flexible element includes at least one annular element that is undulated in the radial direction, or is provided with projections. Flexible elements can also be disposed against a side surface of the bearing ring for damping axial vibrations.

  • Publication number: 20050232525
    Abstract: Disclosed is a decoupling device for mounting a shaft, particularly the shaft of a spherical-disk-shaped enveloping gear operating with a chain as an enveloping means, on a base. The inventive decoupling device comprises an outer bearing ring which has a circular cylindrical outer surface and inside which the shaft is mounted, and an inner surface which is rigidly connected to the base and surrounds the outer surface. At least one radial ondular washer is disposed between the outer surface and the inner surface. Said radial ondular washer allows the inner surface and the outer surface to be radially moved relative to each other to a limited degree while being elastically deformed.
