An electromechanical power steering system for a motor vehicle includes a worm shaft which can be driven by an electric motor and which meshes with a worm wheel coupled to a steering shaft. The worm shaft is rotatably mounted in a bearing which has at least one bearing ring fitted in a retainer that can be displaced relative to the worm wheel. In order to specify an electromechanical power steering system having an improved retainer, which has higher dimensional stability and increased stiffness, according to the invention the retainer has a main body of plastic, which is injection-molded onto the bearing ring as an injection-molded part.

A bearing bush for supporting a motor vehicle part includes an inner tube made of a metal, a sliding sleeve made of a first plastic material and mounted rotatably on the inner tube, and an elastomer bearing which surrounds the sliding sleeve and has at least a first elastomer body and an outer sleeve. A sliding layer made of a second plastic material is applied to an outer circumferential surface of the inner tube, the first plastic material and the second plastic material forming a tribological pairing either of two different polymers from the groups of polyamides, polyoxymethylenes, polyketones, fluoropolymers, polyethylene terephthalates or polybutylene terephthalates, or the tribological pairing being formed from polyketone against polyketone, wherein the polymers of the tribological pairings each are present in a continuous thermoplastic polymer phase.

A roller bearing including a conduction apparatus and a method for conducting electrostatic charges at a roller bearing, the conduction apparatus including at least one elastic conductor having a first conductor section and a second conductor section for forming a contact assembly on the roller bearing, the first conductor section being mounted on a first bearing ring of the roller bearing and the second conductor section being mounted on a second bearing ring of the roller bearing, an electrically conductive connection being established between the first bearing ring and the second bearing ring. The conductor is supported at the first bearing ring, the first conductor section being inserted into at least a straight recess of the first bearing ring.

A bushing structure cooperating with a shaft is disclosed. The bushing structure includes a cylindrical body and an extension portion. The cylindrical body has a shaft hole and the shaft is disposed in the shaft hole. The extension portion is disposed at one end of the cylindrical body and surrounds the cylindrical body. The cylindrical body and the extension portion are made of an iron-contained material.

A valve device includes a body that defines a passage through which a fluid flows, a shaft that is movably supported with respect to the body and defines an axis, a valve element that is fixed to the shaft to open and close the passage; and a cylindrical bearing bush that movably supports the shaft with respect to the body, in which the bearing bush includes a mixed region in which a metal core material and expanded graphite are mixed with each other, and a first expanded graphite region made of only the expanded graphite such that the metal core material is not exposed in an inner circumferential side region in contact with an outer circumferential surface of the shaft.

A closure element (1, 28) for a ball joint (16) in a vehicle. The closure element has a receptacle (2, 29) for accommodating an electronic component (6). To be able to reduce the effort and cost of creating an interface, between the closure element and the electronic component, the closure element (1, 28) has a receptacle (2, 29) which is made of a plastic material and is injection-molded onto one side (3) of the closure element (1).

The invention relates to a drive unit (10) for a vehicle comprising an electric machine (12) having a rotor shaft (14) and a transmission (16) with a transmission shaft (18), wherein the transmission shaft (18) is rotatably mounted in a first housing section (22) by means of a first rolling bearing (20) and the rotor shaft (14) is rotatably mounted in a second housing section (26) by means of a rolling second bearing (24). According to the invention, the transmission shaft (18) and the rotor shaft (14) are coupled to another in a rotationally fixed manner, wherein a third rolling bearing (28) which has an inner bearing ring (30) is arranged at the transition between the transmission shaft (18) and the rotor shaft (14), wherein the inner bearing ring (30) is in contact with the rotor shaft (14) and the transmission shaft (18) with its inner surface (32).

A composite transmission shaft includes a shaft portion, and a flanged end fitting. The flanged end fitting comprises a flared sleeve comprising a tubular portion and a flared portion, and a reinforcement portion fixed to the flared portion of the sleeve. The flanged end fitting and shaft portion have been resin transfer moulded together to form the transmission shaft.
