Abstract: Encoders for bearing units are disclosed. In one example, an encoder includes a magnet part connected to a support part. The magnet part may have a U-shaped cross section formed by a plurality of magnets, wherein the plurality of magnets are situated in alternation with alternating magnetizations. An approximately homogeneous magnetic field may form in a cavity formed by the U-shaped cross section. A signal amplitude of the magnetization along an encoder circumference (U) and within the cavity may be nearly independent of a position of a magnetic-field-measuring sensor.

Abstract: A wheel bearing having a sensor holder (8) to hold a sensor that detects the rotational movement of a wheel, including: a rotating inner race (1) onto which a wheel of the motor vehicle can be mounted, a stationary outer race (2) attached to a motor vehicle, an encoder (4) associated with the rotating inner race (1), a cover (4) arranged on the stationary outer race (2), whereby the sensor holder (8) is formed by a recess that is provided in the cover (3) and that is arranged opposite from the encoder (4), said recess being closed on the side facing the encoder (4) by a partition (7) that is permeable to the magnetic alternating field between the encoder (4) and the sensor.

Abstract: A measuring device for determining an operating state variable of a rotating structural element, in particular a bearing, which has a plurality of components. Specifically, the measuring device has a permanent magnet, an encoder ring for manipulating the magnetic field which is generated by the permanent magnet, a magnetic field sensor, a radio unit for transmitting measurement signals from the magnetic field sensor to an evaluation unit, and an energy converter unit for converting rotation energy into electrical energy. The encoder ring is produced from a ferromagnetic and non-premagnetized material.

Abstract: A wheel bearing unit which has an outer ring, one or two inner rings and load-transmitting rolling elements arranged between the two rings. An orbitally formed shoulder of a wheel hub is provided for the pre-stressing of the wheel bearing unit via the inner ring, and a toothed ring which has an outward-facing radial tooth system is arranged on the inner ring, as is usual in wheel bearing units with all-wheel drive capability. The wheel bearing unit has a small axial width which benefits the handling characteristics of a vehicle by attaching the toothed ring to the orbitally formed shoulder and transmitting the drive torques via this attachment. Welding and a plastically formed tooth system on the orbitally formed shoulder are proposed as examples of such fastening.

Abstract: A method and an assembly device for producing a rotary joint between a drive element and a flange are defined. The drive element and the flange are screwed together by a nut and a bolt of the drive element. The bolt is drawn axially in to a bore in the flange by the rotation of the nut and until the drive element attains a final position in relation to the flange.

Abstract: A sealing arrangement for sealing rolling bearings. The sealing arrangement has a carrier ring for carrying an elastic part which has a radial sealing lip, and therefore a second ring which is movable relative to the carrier ring. The second ring has a cylindrical part provided as a radial seat for the radial sealing lip. A first installation aid is integrally formed on the radial sealing lip and prevents the radial sealing lip from becoming fixed on a second ring, such as, for example, a spinning ring, by ensuring that the radial sealing lip expands at the right time.

Abstract: The invention relates to a device (10, 30) which is used to produce a screw connection between a first component (14, 60) and at least one additional component (15, 70), by means of a fixing screw (12) or a fixing groove (50, 55) and a corresponding fixing element (16, 73). Said device (10, 30) comprises a rotationally mounted tool (11, 31), wherein the fixing screw (12) and/or the fixing groove (50, 55) is maintained in a manner that prevents it from rotating and in an axially fixed manner and wherein the head (20) of the fixing screw (12) and/or the fixing groove (50, 55) is maintained at a distance (S) in relation to the first component (14, 60) as long as both components (14, 60; 15, 70) are joined together. According to the invention, at least one energy accumulator (18, 48) is provided between the tool (11, 31) and the first component (14, 60).
