The invention discloses a rail transit electric window wiper system which comprises a driving assembly of a brushless electric window wiper, and the driving assembly is characterized in that the output end of a driving assembly is connected with a rotating plate, and a Hall sensor is additionally arranged on the rotating plate and used for collecting the pulse number of rotation of a code disc; according to the invention, the influence of large impact on the performance of the window wiper during reversing caused by the quick-return characteristic of the four-bar linkage is reduced, the motion mode of the fast gear is improved, the original constant-speed motion is changed into acceleration and deceleration motion, the speed of the window wiper is increased, the speed of the window wiper is increased, and the reliability of the window wiper is improved. And the speed is reduced in advance before approaching the reversing position of the four-bar linkage.
本发明公开了一种轨道交通电动刮雨器系统,包括无刷电动刮雨器的驱动组成,驱动组成包括:驱动总成的输出端与转动板连接,转动板上增设有霍尔传感器,用于采集码盘转动的脉冲数,以及停止位置的复位信号作为每个周期的起始位信号,实现转动位置的检测,本发明降低因四连杆的急回特性造成换向时冲击较大对刮雨器性能的影响,对快速档的运动方式进行了改进,由原恒定速度运动更改为加减速运动,再接近四连杆的换向位置前提前进行减速。
