Abstract: In view of the common manual mechanical shift mode of coal mine explosion-proof hydraulic transmission vehicle, a set of automatic shift control system of explosion-proof hydraulic transmission vehicle is designed in this paper. First of all, it briefly introduces the structure of the hydraulic drive system of mining explosion-proof vehicles and the characteristics of each component. Based on the principle of the highest torque converter working efficiency, the best power shift rule is deduced. Then the mine explosion-proof automatic shift control system components and functions were introduced. Finally, the bench test confirms the practicability of this automatic shift control system and shift control strategy.
