Abstract: A wheelset bearing for a rail vehicle has a generator which is designed as a claw-pole generator, which includes at least one non-rotating claw ring, as well as a sensor system supplied with electrical energy by the generator The sensor system has a plurality of sensor system modules which are at least partially fastened to a sensor carrier placed on the claw ring and which are connected to a common data line.

Abstract: A plain bearing assembly of a rotational element on a bearing bolt includes a bearing bolt, a bearing sleeve, which is non-rotatably mounted on said bolt and which comprises a first radial bearing surface formed on its outer periphery, and a rotational element which is rotatably mounted on the bearing sleeve and which is mounted on the first radial bearing surface via a second radial bearing surface in such a way that it can slide. Axial bearing washers, which project radially beyond the bearing sleeve, are secured to both end faces of the rotational elements. The washers run against axial bearing surfaces of the bearing sleeve, and axial flanks of the bearing sleeve form axial bearing surfaces for the axial bearing washers.

Abstract: A plain bearing arrangement for a shaft loaded with a circumferential radial force, having a bearing ring arranged in a rotationally fixed manner in a housing component and having a first running surface formed on the inner circumference, and a second running surface formed on the outer circumference of the shaft or on the outer circumference of a sleeve arranged on the shaft, the second running surface being mounted in a sliding manner on the first running surface, wherein a device for axially feeding a lubricant to an end side of the shaft is provided, and at least one axially extending, radially open groove that is axially open in a direction of the end side of the shaft is formed in the second running surface.
