Technical Field

The invention relates to the technical field of rain wiping of motor train units, in particular to a brush rod device of a rain wiper.

Background

As is well known, the wiper blade includes a motor, a decelerator, a four-bar linkage, a wiper arm spindle, a wiper blade, and the like. When a driver presses down a switch of the windscreen wiper, the motor is started, the rotating speed of the motor drives the swing arm through the speed reduction and torque increase effects of the worm gear and the worm, the swing arm drives the four-bar mechanism, the four-bar mechanism drives the rotating shaft arranged on the front wall plate to swing left and right, and finally the rotating shaft drives the wiper blade to wipe the windscreen.

In recent years, with the support and investment of national policies, domestic rail vehicles show a well-spraying development trend, the trend of modular, standardized and serialized development of parts of rail vehicles is more and more obvious, and the rain wipers of rail vehicles are no exception. The wiper of current rail vehicle generally uses the motor to drive the doctor-bar as the power supply and scrapes the brush to glass, and the wiper has the three different frequency's in high frequency, low frequency, clearance repeated oscillation to scrape the brush, and motor speed, stationarity have serious influence to its life-span and reliability, and then lead to the normal use that can not of wiper, bring the potential safety hazard for rail vehicle's normal driving.

Therefore, to improve the smoothness and the durability of the wiper blade, it is necessary to improve the smoothness and the durability of the brush bar device.
