通过分析液力传动为动力控制类煤矿用四驱防爆车辆存在的问题,提出动力控制装置的改进设计方案。该设计采用液控型动力切断装置,动力换挡变速箱在配置该控制装置后,可以实现传动装置与车轮之间的动力切断及行车制动器与换档离合器操纵之间的联锁,满足在行车制动和停车制动时均具备自动动力切断功能,降低和消除了在实施制动时车辆产生的寄生功率。该系统结构合理,通用性好,可实现现有车辆的直接改造。
By analyzing the existing problems of four-drive explosion-proof vehicle with hydraulic drive for power control coal mine, an improved design scheme of power control device is proposed. The design uses liquid-controlled power cut-off device, the power shift transmission in the configuration of the control device, you can achieve power transmission between the transmission and the wheel and the service brake and shift the interlock between the clutch control to meet the driving Braking and parking brakes are equipped with automatic power off function, reducing and eliminating the parasitic power generated by the vehicle in the implementation of braking. The system has reasonable structure and good universality, which can directly transform the existing vehicles.
