Abstract: A measurement bearing includes a rotational axis and at least one first bearing ring. The first bearing ring defines a main supporting direction and a circumferential direction extending transversally with respect to the main supporting direction. The first bearing ring also has at least one first recess in which a sensor device is arranged. The sensor device is adapted to sense a sensing variable which represents the bearing forces which are applied to the first bearing ring. The first bearing ring further has at least one second recess, in which a further sensor device is arranged. The first recess and the second recess are arranged a distance apart in the circumferential direction and transversally to the circumferential direction.

Abstract: The invention relates to a measurement bearing, in particular for a wheel set of a rail vehicle, having a rotational axle and at least one first bearing ring (103), wherein the first bearing ring (103) defines a main supporting direction and a circumferential direction extending transversely with respect to the main supporting direction, and the first bearing ring (103; 203) is designed to take up bearing forces which have at least one force component in the main supporting direction, and during operation said bearing forces are applied to the first bearing ring (103) via a plurality of rolling bodies (104). The first bearing ring (103) has at least one first recess (105) in which a sensor device (110) is arranged, wherein the sensor device (110) is designed to sense a sensing variable which represents the bearing forces which are applied to the first bearing ring (103).

Abstract: In order to reduce torsional vibrations and wheel slip in a wheel set for a rail vehicle the wheel set comprising a pair of wheels connected by an axle is provided with a vibration absorbing device comprising a mass, resiliently mounted on the wheel set and adapted to oscillate at the resonant frequency of torsional vibrations of the wheel/axle system. A method of preventing or reducing torsional vibrations in a wheel set of a rail vehicle is also disclosed, the method comprising determining the resonant frequency of torsional vibrations of the wheel/axle system and resiliently mounting a vibration absorbing device in the form of a mass, on the wheel set, the mass and its resilient mounting being selected to oscillate at or near that resonant frequency.
