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 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.

A wheel bearing apparatus has a magnetic encoder 14 mounted on an inner ring 5 opposing the rotational speed sensor 16, via the cap 10 and an air gap. The cap 10 has a cylindrical fitting part 10a press-fit into an inner circumference of an end of the outer member 2. A shielding part 10c extends radially inward from the fitting part 10a and has an annular disc shape. A detection part 16a of the rotational speed sensor 16 is arranged close to or in contact with a side surface of the shielding part 10c. The cap 10 is formed of austenitic stainless steel sheet based on SUS 304. The carbon (C) content is reduced and the nickel (Ni) content is increased. A difference of magnetic flux density between a martensitic transformation part and non-martensite part is 1.4 mT or less.

A hub bearing module for a lightweight suspension upright or knuckle of a vehicle, the hub bearing module including a wheel bearing and a bearing connection interface to the suspension upright or knuckle, the bearing connection interface being arranged coaxial with the rolling bearing and including a first sleeve element and a second sleeve element arranged radially outside the first sleeve element and including a composite, preferably BMC (Bulk Molding Compound) annular body having a radially inner lateral surface mechanically coupled to the first sleeve element and a radially outer lateral surface configured to mechanically and chemically couple with the suspension upright or knuckle.

A ball joint having a ball pin and a housing. The ball pin together with the ball is accommodated in the housing to move in a rotational and pivotal manner. The ball is at least partially surrounded by a structural component. The structural component is essentially formed from a fiber-plastic composite structure and at least partially forms the housing.

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 sealing system for a roller bearing including a first annular shield and a first sealing cover. A first face of each that includes a coupling surface that is covered with a rubbery coating made of a synthetic rubber. The coupling surface of the first annular shield is coupled to a corresponding coupling surface of a rotating ring of the roller bearing, and the coupling surface of the first sealing cover is coupled to a corresponding coupling surface of an outer ring of the roller bearing. Each of the first annular shield and the first sealing cover is pressed from a metal sheet with a first face entirely rubberized with the rubbery coating.

The invention relates to a method for manufacturing a pulley device for a tension roller or a roller of a transmission element providing a pulley, at least two rolling-element bearings and a sleeve, the rolling-element bearings being assembled adjacently on the sleeve before the pulley is formed by injecting material onto the rolling-element bearings.

The invention relates to a hinge (1) having two hinge arms (2, 3) that can be moved in an articulated manner relative to each other, wherein each hinge arm accommodates a sliding bearing element (4, 5), and a sliding bearing bushing (6) is situated between the sliding bearing elements. The invention also relates to a method for producing such a hinge. The aim of the invention is to design a hinge which can be produced easily and with precision and has high durability.

A bearing carrier is provided. The bearing carrier including: a bearing body of a first material having a shaft-receiving aperture and a bridge land with a finger cut to channel fluid pressurized by intermeshing of gears rotatably supported by the bearing carrier into an outlet defined by a housing enveloping the bearing carrier, wherein the bearing body includes a bearing face configured to be in a facing spaced relationship with the gears, wherein the bearing face includes a second material integral with the first material, wherein at least one of the first material and the second material define a portion of the bearing face of the bearing body extending about the shaft-receiving aperture, the portion of the bearing face excluding the bridgeland.
