What is the size of Volkswagen horn rivets?

[Daedalus]

Volkswagen horn's original rivet size: 4.7X15mm. Typically used on wipers, at the connection point between the wiper swing arm and the wiper blade. Wiper operation principle: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanism. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives the four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion. Basic introduction to wipers: Refers to the blade structure installed in front of the windshield, composed of the motor, reducer, four-bar linkage mechanism, wiper arm spindle, wiper blade assembly, etc. Its main function is to remove rain, snow, and dust that obstruct the view on the windshield.
