Emergency brake system and method for truck for mine

The invention relates to an emergency brake system and a method for a truck for a mine, which belong to the technical field of the truck for the mine .The emergency brake system and a method for a truck for a mine comprises an engine, a generator, control equipment, a mechanical brake, a wheel hub motor, a speed reducer, a tire, a heat radiation fan, a resistor grid and an emergency brake handle, wherein the engine is electrically connected with the generator, the generator is electrically connected with the control equipment, the control equipment is electrically connected with the mechanical brake, the wheel hub motor, the resistor grid and the emergency brake handle, the wheel hub motor is electrically connected with the speed reducer, the speed reducer is connected with the tire, and the heat radiation fan is arranged at the bottom of the resistor grid. The emergency brake system has the beneficial effects that the wheel hub motor is provided with a ventilation cooling facility, the reliable cooling can be provided for the wheel hub motor, the electrification reverse dragging moment of the wheel hub motor is greater, and greater brake moment can be provided for the emergency brake for reducing the emergency brake time and distance. In addition, the brake time is shorter, so the use of the mechanical brake can be reduced, and the damage rate of the mechanical brake is reduced.
