摘要

The bearing unit has a speed measuring device detecting speed of a rotating spindle of a rail mounted vehicle. A permanent magnet (03) is provided at an axial end (01) of a wheel axle and is connected with the axle in a torque proof manner. A sensor (06) e.g. Hall-Sensor, determines a direction magnetic field acting on the sensor and produces an electrical output signal based on the direction of the field. An electronic circuit converts the output signal into a speed sensor pulse. The sensor determines direction of the field in form of a direction vector such as polar or Cartesian coordinates. An independent claim is also included for a sensor arrangement for measuring speed of an axle or shaft, which rotates relative to a frame.
