A seal arrangement for a wheel bearing having first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which bearing parts rolling elements are guided. The sealing arrangement includes: a carrier element, which is connected to the first bearing part and an elastic element is provided on the carrier element. The elastic element has at least one sealing lip, and the carrier element has a fastening section, which is connected to the first bearing part. A stop part is fastened to the second bearing part with which the at least one sealing lip is in rubbing contact. The wheel bearing flange has an axial projection at least partially surrounds an axial projection of the first bearing part, and an inner surface of the axial projection of the wheel bearing flange forms a seat for the stop part.

Sealing arrangement for a wheel bearing

A wheel bearing having a sensor holder () to hold a sensor that detects the rotational movement of a wheel, including:

Wheel bearing having a sensor holder

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.

Measuring device for determining an operating state variable of a rotating structural element, in particular a bearing

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.

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.

Method for producing a rotary joint

The invention relates to a device () which is used to produce a screw connection between a first component () and at least one additional component (), by means of a fixing screw () or a fixing groove () and a corresponding fixing element (). Said device () comprises a rotationally mounted tool (), wherein the fixing screw () and/or the fixing groove () is maintained in a manner that prevents it from rotating and in an axially fixed manner and wherein the head () of the fixing screw () and/or the fixing groove () is maintained at a distance (S) in relation to the first component () as long as both components () are joined together. According to the invention, at least one energy accumulator () is provided between the tool () and the first component (). At least the joining force and the maximum and the total desired clamping force of the prepared screw connection can be predetermined by means of the at least one energy accumulator (). The invention also relates to a fixing groove () for the inventive device and/or the inventive method.
