Abstract

The invention provides a pneumatic window wiper motor position detecting device. The pneumatic window wiper motor position detecting device comprises a code wheel, a mounting seat and a controller; the code wheel is fixedly mounted on a power output shaft of the motor; position detecting elements are installed on the left side and the right side of the code wheel; the mounting seat is fixed to a shell of the motor and disposed to directly face the code wheel; the mounting seat is provided with two sensors for detecting the position detecting elements on the code wheel; and the controller is separately connected with the two sensors and a reversing solenoid valve of the motor for controlling the reversing of the reversing solenoid valve after one of the sensors detects the position detecting elements. The pneumatic window wiper motor position detecting device facilitates the improvement of the reliability of the detecting device.

Description

technical field [0001] The invention relates to the field of wipers, in particular to a motor position detection device for a pneumatic wiper. Background technique [0002] Rail vehicles have higher and higher requirements on the reliability of components. Wipers on rail vehicles are mounted on the PTO shaft of the motor. It is often necessary to check the limit position of the wiper swing in order to control the reverse rotation of the motor in time. At present, the pneumatic wiper motor usually uses a single sensor to detect two limit position signals. Under complex working conditions, there is a problem that the position of the signal cannot be judged, and the reliability is low. Contents of the invention [0003] Aiming at the defects in the prior art, the invention provides a device for detecting the position of a pneumatic wiper motor, which is convenient for improving the reliability of the detection device. [0004] A position detection device for a pneumatic wi...
