ELECTROMOTIVE WINDSCREEN WIPER DRIVE

摘要

Electromotive windscreen wiper drive for vehicles, with a shaft (1) driven when the drive is switched on and with at least one sensor arrangement for generation of signals for activation of dispensing of a washing and cleaning fluid precisely at the wiping angle onto a vehicle screen respectively when the shaft has reached at least one first angular position (WPA1, WPB1) and/or for termination of dispensing of the washing and cleaning fluid in at least a second angular position (WPA9, WPB9), whereby the sensor arrangement, which presents at least one sensor element (6, 7) interacting with a magnetic field of at least one permanent magnet (4), with a rotating shaft and with a thereby induced relative movement between the at least one permanent magnet and the at least one sensor element, issues phase-displaced or time-displaced output signals (AS6, AS7).
