An exhaust gas turbocharger for an internal combustion engine may include a rotor with a turbine wheel of a turbine, a compressor wheel of a compressor and a shaft. The shaft may be connected to the turbine wheel and to the compressor wheel in a rotationally fixed manner. A bearing cartridge may be included for mounting the rotor in a housing. The bearing cartridge may have an inner sleeve arranged on the shaft axially between the turbine wheel and the compressor wheel with respect to an axis of rotation and an outer sleeve arranged coaxial thereto. The outer sleeve may be rotatably mounted on the inner sleeve via at least one rolling body. At least two damping rings may be included which are coaxially arranged on the outer sleeve axially spaced from one another and supported on a respective bearing section of the housing.

A gear shaft of an output gear in a speed reducer of an in-wheel motor driving device is supported at a first end thereof and a second end thereof with respect to a housing. The gear shaft of the output gear is formed with a spline hole. The spline hole provides a spline-connection with an output shaft of a wheel hub.

In a power-transmitting mechanism with rolling-element bearing according to the present invention, an inner ring has plural inner ring members disposed in series in an axial direction, an outer ring has plural outer ring members respectively cooperating with the plural inner ring members. Plural rolling elements are disposed between the cooperating inner ring members and outer ring members. A retainer has plural partitions retaining the plural rolling elements at predetermined intervals in the circumferential direction such that rolling elements disposed between one pair of cooperating inner ring and outer ring members and rolling elements disposed between another pair of cooperating inner ring and outer ring members orbit the corresponding inner ring members in a synchronized manner, and a connector connecting the plural partitions such that the plural partitions integrally rotate around an axis.

A turbocharger includes a turbine, a compressor, and a bearing housing forming a bearing bore. A bearing arrangement is disposed between a shaft interconnecting the turbine and compressor wheels, and the bearing housing. The bearing arrangement includes first and second bearings formed between an outer bearing race element disposed within the bearing bore an inner bearing race element disposed within the outer bearing race element and between the outer bearing race element and the shaft. The inner bearing race element includes a flared portion extending radially outwardly to provide torsional and bending rigidity to the shaft.

The invention relates to an exhaust turbocharger, which contains a modular bearing, which is designed for bearing a shaft and is arranged between a compressor and a turbine, wherein the bearing has a bearing housing having a receptacle chamber, wherein a bearing assembly module can be or is installed in the receptacle chamber and can be non-destructively removed, the receptacle chamber being sized such that optionally either a bearing assembly module having a rolling bearing or a bearing assembly module having a slide bearing can be installed, the receptacle chamber having an interface, which is designed to contact the bearing flange of a bearing assembly module inserted into the receptacle chamber, the interface being designed to connect an oil gallery passing through the bearing housing to one or more oil galleries passing through a bearing flange of the bearing assembly module.

A wheel bearing arrangement for a vehicle, comprising at least one roller bearing, wherein at least one of the roller bearings is a ball bearing, which includes an inner ring and an outer ring, wherein both rings have raceways for balls being located between the rings. To ensure a sufficient lifetime of the roller bearings and to minimize the friction in the bearing, the at least one of the rings of the bearing arrangement is made from a ball bearing steel produced by a powder metallurgical process using a powder metallurgy component including 0.5 to 2.0 weight-% C, a maximum of 0.035 weight-% S, 3.0 to 5.0 weight-% Cr, 1.0 to 4.0 weight-% V, 1.0 to 12.0 weight-% W and 2.0 to 12.0 weight-% Mo, wherein at least one raceway has a radius and the balls have a diameter which fulfills the equation: radius/diameter>0.53.

In a vehicle suspension assembly a sensorized system applied to a wheel hub unit, in which radially outer cylindrical surface of an outer ring of the wheel hub unit configured for coupling to a suspension upright or knuckle has four circumferential flats formed to be angularly spaced from each other on the radially outer lateral cylindrical surface, each flat delimiting a plane surface which extends axially over a pair of annular tracks for rolling bodies of the outer ring; each flat carries integrally a sensor module including a pair of extensometers positioned parallel to each other and each at the position of a respective annular track, orientated in a circumferential direction so as to extend along a circumferential development of the annular track; an electrical circuit picks up a signal from each sensor module and sends it to a data socket carried by the suspension upright or knuckle.

A nut is used with being fixed to a sensor cap. The sensor cap is attached to an outer ring of a bearing in a wheel bearing device of an automobile. The sensor cap includes a sensor holder for holding a magnetic sensor. The nut is made of steel, and has a screw portion in which a bolt is screwed to attach the magnetic sensor to the sensor cap. A surface of the nut is coated with a zinc-nickel alloy plating layer with a nickel eutectic ratio of 8 to 18%.

The invention relates to an attachment point (1) comprising a connecting element (3) which comprises a section (5) for connecting an attachment device, a seat (9) for a fastening device (11) and at least one pair of rolling bearings (23) between the seat (9) and the connecting element (9), wherein the connecting element (3) is rotatable relative to the seat (9) and wherein the rolling bearings (25, 27) of the pair of rolling bearings each comprise at least one rolling element (29). In order to provide an attachment point that exhibits little wear, is easily rotated also when lifting heavy loads and is easy to install, it is according to the invention provided that the rolling bearings (25, 27) of the pair of rolling bearings (23) comprise an outer race (39, 41) attached to the connecting element (3).
