The invention discloses a mining underground unmanned transportation electric vehicle which comprises an electric control system, a motor, wheels, a driving part and a braking part, the braking part comprises a braking disc synchronously rotating with the wheels and a retarder fixedly connected with a vehicle frame, the braking disc is provided with a smooth, continuous and periodically concave-convex changing abutting face, and the braking disc is provided with a driving part. The concave face and the convex face can completely coincide, and the telescopic end of the retarder abuts against the abutting face. According to the mining underground unmanned transportation electric vehicle, braking is achieved through the electromagnetic braking function of the motor, final braking and parking are achieved through the throttling effect of the retarder, relative to the situation, related heat dissipation components are easier to arrange, the temperature generated by braking is easier to control, the influence of the temperature on braking force is small, and the braking effect is good. And the problem of sparks caused by the fact that the brake pad is not replaced in time can be avoided, and meanwhile the reliability and timeliness of braking after power failure are improved.
本申请公开了一种矿用井下无人驾驶运输电动车辆,包括电控系统、电机、车轮、驱动件和制动件,所述制动件包括与车轮同步转动的制动盘和与车架固定连接的减速顶,所述制动盘具有平滑、连续、周期凹凸变化的抵接面,且凹面和凸面能够完全重合,所述减速顶能够伸缩的端部抵接在抵接面上。一种矿用井下无人驾驶运输电动车辆,由电机的电磁制动功能实现制动,再由减速顶的节流作用实现最终的制动和驻车,相对而言,相关的散热部件更容易设置,更加容易控制制动产生的温度,制动力受温度的影响较小,也能避免制动片未及时更换产生的火花问题,同时,也提高了断电后制动的可靠性和及时性。
