  • Patent number: 9689463
    Abstract: A roller (20) for a pendulum mass (4, 5, 6) of a centrifugal force pendulum (1), including a rolling section (42), a first maintaining section (26) and a second maintaining section (27). The maintaining sections have a larger diameter than the rolling section, and the roller (20) has a width (44) which is smaller or the same size as the first depth (9) of the centrifugal force pendulum. Due to roller (20), a centrifugal force pendulum can be constructed for particularly flat couplings. In particular, the total weight of the friction clutch is reduced and the mounting is simplified.

  • Patent number: 9625277
    Abstract: An ABS encoder arrangement for a driven wheel bearing unit, with a multi-pole ring, a sensor device with a sensor head, and an annular cap element that has an annular wall portion which shields a cap interior against the exterior. The annular wall section extends through an intermediate region lying between the multi-pole ring and an end face of the sensor head. An extension concentric with the axis of rotation of the multi-pole ring and extending axially over a circumferential area of an articulated shaft head is connected to the annular wall section on a side facing away from the multi-pole ring. In the end portion of the extension facing away from the multi-pole ring and extending over the articulated shaft head, the extension forms a circumferential profile that radially stiffens the extension and forms an annular edge which extends into a circumferential groove of the articulated shaft head and forms a channel cross-section open to the outside.

  • Publication number: 20160176030
    Abstract: A simplified installation tool for installing a cover strip in a linear guide rail assembly is provided. The installation tool includes a body having a channel that extends across a bottom surface of the body that is adapted to receive a guide rail. The channel is defined by an upper surface with a lead-in angled projection and sides defined by two L-shaped guide portions that extend from the upper surface and that face each other. Two undercut areas of the channel are located between the L-shaped guide portions and the upper surface of the channel. Retention tabs of the installation tool can attach to the carriage of the linear guide rail assembly. The lead-in angled projection provides a downward force on the cover strip as the carriage travels along the guide rail to press the cover strip into a flattened state within a slot of the guide rail.
