The invention relates to the technical field of rail transit, and discloses an anti-slip structure for a rail vehicle. The anti-slip structure comprises an output shaft and a driven shaft, wherein theoutput shaft is in transmission connection with a first liquid motor through a gear, and the driven shaft is in transmission connection with a second liquid motor through a gear. According to the anti-slip structure for the rail vehicle, through hydraulic transmission, when the difference between traction force and adhesive force is small, part of traction force of a traction wheel is transmittedto a non-traction wheel, so that slipping is avoided; when the difference between the traction force and the adhesive force is large, sand blasting is triggered, and the contact surface is increased,so that the anti-slip structure normally operates; when the difference between the traction force and the adhesive force is too large, the traction force is actively consumed, so that slipping is avoided; and by means of hydraulic pressure and air pressure transmission, the function of preventing wheels from slipping can be achieved even when a sensor breaks down or fails, and the reliability ofequipment is improved through direct force transmission.
本发明涉及轨道交通技术领域,且公开了一种用于轨道车辆的防打滑结构,包括输出轴和从动轴,所述输出轴通过齿轮传动连接有第一液体马达,所述从动轴通过齿轮传动连接有第二液体马达。该用于轨道车辆的防打滑结,通过液压传递,在牵引力和黏附力相差不大时,将牵引轮的部分牵引力传递到非牵引轮上,从而避免打滑,当在牵引力和黏附力相差较大时,触发喷砂,增加接触面,使其正常运行,当在牵引力和黏附力相差过大时,主动消耗牵引力,避免发生打滑,并且,通过液压和气压传递,一方面,即使在传感器故障或失效时,也能发挥阻止车轮打滑的功能,另一方面,直接的力的传递也提高了设备的可靠性。
