Abstract: Disclosed embodiments relate to a windscreen wiper drive of a windscreen wiper device of a rail vehicle. The drive includes at least one electric motor, a gear, the input shaft of which being connected to an output shaft of the electric motor, wherein an output shaft of the gear is provided for driving at least one windscreen wiper arm of a windscreen wiper, which arm swings back and forth with the output shaft, a rotation angle sensor unit, which detects a rotation of at least one element of the windscreen wiper drive, and a mechanical rotation angle limitation, which mechanically limits a rotational movement of at least one element of the windscreen wiper drive. The electric motor is formed by a disc motor and the gear is formed by a planetary gear.

Abstract: A pneumatic system for operating a drive for a windshield wiper for a rail vehicle, wherein the windshield wiper drive has a piston guide device that has a first connection and a second connection opposite the first connection. At least one piston in the piston guide device carries out linear movements in opposite directions along the main direction of extension of the piston guide device to bring about an alternating rotational movement of the wiper shaft. The pneumatic system has a supply connection for a compressed air supply, wherein the supply connection is connected to the first connection via a first normal operation connection line and a first emergency operation connection line arranged parallel thereto and to the second connection via a second normal operation connection line and a second emergency operation connection line arranged parallel thereto.
