Description

technical field

[0001] The invention relates to the technical field of wiper for EMUs, in particular to a wiper. Background technique

[0002] As we all know, the wiper includes a motor, a reducer, a four-bar linkage, a wiper arm spindle, a wiper blade, and the like. When the driver presses the switch of the wiper, the motor starts, and the speed of the motor drives the swing arm through the deceleration and torque increase of the worm gear. , and finally the rotating shaft drives the scraper to sweep the windshield.

[0003] In recent years, with the support and investment of national policies, domestic rail vehicles have shown a blowout development trend. Rain gear is no exception. At present, the wipers of rail vehicles generally use motors as the power source to drive the scrapers to wipe the glass. The wipers have three different frequencies of high frequency, low frequency, and gap. Its service life and reliability have a serious impact, and then lead to the non-no...
