基于双电机驱动的防爆车辆等转矩分配差速技术

Equal Torque Distribution Differential Technology of Explosion-proof Vehicle Based on Dual Motor Drive

当前辅助运输中,双电机驱动防爆车辆在煤巷井下作业时,会出现两侧转速失调的状况,导致轮胎严重磨损,现根据双电机驱动运煤车的结构和工作原理,设计电子差速控制系统,建立了仿真模型,分析了直行工况和转向工况下,两侧轮胎的两侧轮胎的转速、转速比、滑转率及整车的转弯半径,可以有效改善行驶过程中轮胎受力情况,提升其使用寿命。

In the current auxiliary transportation,when the double motor driven explosion-proof vehicle is working underground in the coal roadway,the rotational speed on both sides will be out of balance,resulting in serious tire wear.Now,according to the structure and working principle of the double motor driven coal truck,the electronic differential control system is designed,the simulation model is established,and the rotational speed,rotational speed ratio,slip rate and turning radius of the whole vehicle on both sides of the tires under the straight driving condition and steering condition are analyzed.It can effectively improve the stress of tires during driving and improve their service life.
