STOP BRAKE FOR RAILWAY TRACTION VEHICLES

摘要

The invention relates to a holding brake for track-bound motor vehicles (1) with the holding brake being realized by means of at least one electric machine (2) which has a rotor and a stator. A control system for the electric machine is hereby provided to so control the operation of the electric machine (2) that the position of the rotor in the stator remains constant when exposed to an external torque. In other words, the electric motor (2) is used as holding brake instead of a pneumatic holding brake. In this way, the holding brake is advantageously not subject to any wear since the holding forces are produced magnetically and not by mechanical forces. In addition, no noise is generated by the use of the holding brake according to the invention. Furthermore, a starting jolt is prevented, when the electric motor (2) used as a holding brake is also used as a drive motor.
