普通客车的伸缩式踏板占用较大的车下空间,而高速动车组车外的固定踏板则会产生一定的阻力,不仅影响列车的速度,也影响了列车的整体美观。为了改变这种现状,设计一种新型的踏板,裙板气动翻板。该踏板设计成旋转翻出式,翻出后可以作为踏板,满足司机和检修人员上下车的要求,收回后,作为裙板保护车下设备,而且该踏板占用较小的车下空间。 The ordinary passenger car telescopic pedal occupy a larger space under the car, and high-speed EMU outside the fixed pedal will have some resistance, not only affect the speed of the train, but also affect the overall appearance of the train. In order to change the status quo, a new type of pedal, apron pneumatic flap is designed. The pedal is designed to rotate out of the way, turn out can be used as a pedal to meet the drivers and maintenance personnel on and off the request, retracted, as a skirt to protect the car equipment, and the pedal occupy less space under the car.
