Windscreen wiper drive of a windscreen wiper device of a rail vehicle

A windshield wiper drive of a windshield wiper apparatus of a rail vehicle, the drive comprising:

• at least one electric motor;
• a gearing, an input shaft of which being connected to an output shaft of the electric motor, wherein an output shaft of the gearing is provided for driving at least one windshield wiper arm of a windshield wiper, which pivots back and forth with the output shaft of the gearing;
• a rotational angle sensor device which detects a rotation of at least one element of the windshield wiper drive;
• and
• a mechanical rotational angle delimiter which mechanically limits a rotational movement of at least one element of the windshield wiper drive, wherein
• the electric motor is formed by a disk motor, and the gearing is formed by a planetary gearing,
• wherein said windshield wiper drive has, at the output side, a main arm shaft, which is driven in rotation by the output shaft of the planetary gearing, and a parallel arm shaft extending from a supporting wall in the same direction as the main arm shaft, which is driven in rotation by rotation of the main arm shaft, wherein the main arm shaft is designed for the fastening of a main arm and the parallel arm shaft is configured for the fastening of a parallel arm of the windshield wiper.
