Abstract: In a device for the electrical connection of preferably ALS sensors in or on roller bearings of truck wheels, a seat casing is provided for the transfer of the ALS sensor's signals from one side of the bearing ring to the other, which seat casing is located between the bearing ring and, e.g., the shaft. It serves as signal conductor or it is equipped with conductors consisting of wires, flat band conductors, conductive layers, or the like. The connection to the ALS sensor or a plug ring with a connecting cord, occurs preferably by way of slip rings 10, to exclude all operational interference induced by a creeping motion in a circumferential direction of the otherwise fixed bearing ring. In addition, without conductors or a cord the bearing will be simpler to assemble.

Abstract: An electrical connection, preferably for ALS sensors incorporated in wheel bearings, is installed coaxially on the wheel bearing and its side surface. It is equipped, for example, with slip rings which operate in conjunction with the electrical contacts of the ALS sensor which is solidly attached to the wheel bearing. This simplifies the manufacture and handling of the wheel bearing during transportation and assembly. In particular, the risk of damage to the connecting cord is reduced during operation.

Abstract: A drive device for pumps consists of a drive pulley to drive a shaft. The shaft assembly includes an inner bearing seated in the housing bore, an outer bearing seated on a neck of a pump cover, a cover disk with an outer edge, covering the outer bearing and the neck of the pump cover laterally from the outside and is connected to the drive pulley, and a center of the shaft, a spring for the automatic play eliminating adjustment of the radial and axial load-supporting outer and inner bearing.

Abstract: A device for sealing and generating electrical pulses in a bearing assembly including fixed and rotating bearing rings especially a wheel bearing for motor vehicles. The device consists of a sealing section on the fixed bearing ring with an embedded pulse generator for detecting rotational movement and a sealing section on the rotating bearing ring having cells a certain distance apart from each other which activate the pulse generator. The fixed bearing ring (4, 19) rotates with respect to the sealing section (2) which is secured against rotation by way of a machine element (1, 24), which holds the fixed bearing ring (4, 19).

Abstract: A spring ring is arranged in an annular gap of a pair of outer bearing rings in an arrangement for fastening a rolling bearing in the bore of a housing. A groove is provided in the housing for receiving the spring ring. A holding ring is mounted on the outer surface of the bearing outer ring, the holding ring having a collar aligned to hold the spring ring within the annular gap during the disassembled condition of the bearing. The holding ring has an axial surface adapted to engage the end of the housing during assembly, to enable the holding ring to be forced axially along the outer surface of the bearing outer ring. The holding ring futher has an end away from the spring ring adapted to form a seal with the bearing inner ring.

Abstract: In a hydraulically operable release arrangement for clutches, especially for vehicle clutches, the release force is transmitted to the plate spring or the like of the clutch by way of a piston, a fixed bearing ring, a multiplicity of rolling bodies, and a rotating bearing ring. The piston is movably arranged in a housing and is biased by a helical spring arranged in a pressure space formed between the piston and the housing. The piston and the housing are each provided with an axial projection. In order to secure the piston against rotation and to damp vibrations in the piston without additional machining or special parts, the helical spring is arranged with its spring ends abutting the axial projections such that rotation of the piston in the direction of rotation of the rotating bearing ring is prevented.

Abstract: A rolling element bearing has annular seals between the races for preventing entry of dirt into the lubricant space. The seals are held to one of the races, and have weakened portions on at least one location about their periphery to enable excess pressure within the lubricant chamber to escape.

Abstract: An hydraulically operated clutch release has an annular piston hydraulically moveable in an annular chamber. A felt ring is mounted on a shoulder of the piston away from the chamber, to engage the bore surface of the chamber, and a holding ring is snapped onto the end of the shoulder to hold the felt ring on the shoulder. An extension of the holding ring forms a seal with the bore on the chamber, and defines, with the felt ring a dust catching recess.

Abstract: A wheel bearing has inner and outer bearing rings each having a radially outwardly directed flange, and a plurality of rolling elements arranged between the rings. An annular seal has a support element affixed to the outer ring, the support element terminating in an annular elastic element of oil resistant material that is slidably engages the inner ring. A cover extends over the flange of the inner ring and has an end terminating radially spaced from a shoulder of the outer ring, to define a sealing gap. The intermediate portion of the cover defines a lubricant accumulation space.

Abstract: In a bearing assembly particularly for wheel bearings comprising an inner ring having at least one radially outwardly directed fastening flange, an outer ring and a plurality of rolling elements in the annular space between the rings, a cap secured to the inner ring having a radial section extending between the outer ring and fastening flange and a seal ring fastened to the outer ring which slides on the cap, means defining at least one space between the radial cap section and the fastening flange of said inner ring, said space being filled at least partly with means which inhibits heat transfer from the inner ring to the cap.

Abstract: A thrust ball bearing has an outer cup-shaped ring and an inner cup-shaped ring. A ball bearing assembly of a plurality of balls and a cage is arranged between the closed ends of the bearing rings. The closed bottom of the outer ring is curved, with the center of curvature being on the side thereof toward the bearing assembly. The bearing rings have thin walls, and the thrust ball bearing is particularly adaptable for use as a clutch throw-out bearing.

Abstract: A wheel bearing unit for motor vehicles with at least two bearing parts which can turn relative to one another, between which at least two rows of roll bodies are arranged. The bearing parts each have an outer portion, the first of said outer portions being fastened to the vehicle, the other to the wheel. The fastening is effected by mating threads axially aligned between one outer portion and a connecting part. Means are provided for securing the mated threaded portions against relative loosening rotation.

Abstract: A hydraulic release mechanism for automobile clutches comprising a housing open at one end and a bearing. The bearing comprises a rotating race ring adapted to be connected to the operating member of the clutch, a non-rotating race ring and a plurality of roller elements located therebetween. The non-rotating race ring is slidably arranged with respect to the housing, and seal means is arranged on the non-rotating race ring between it and the surface of the housing to enclose the housing to form a pressure chamber while permitting the race ring to move on introduction of pressurized fluid into the housing.
