STOP BRAKE FOR RAILWAY TRACTION VEHICLES

摘要

The invention relates to a stop brake for railway traction vehicles (1) consisting of at least one electric motor (2) provided with a rotor and stator. Said electric motor is controlled in such a way that the position of the rotor in the stator remains constant when it is exposed to an external torque, i.e. the electric motor (2) is used in the form of a stop brake instead of a pneumatic stop brake, thereby, the inventive stop brake is not exposed to any wear since stop forces are produced magnetically and not mechanically. In addition, no noise is generated by the use of the inventive stop brake. Said invention also makes it possible to avoid a starting jerk when the electric motor (2) serving for a stop brake is used in the form of a drive motor.
