Mine car self -actuating brake and speed control unit

The utility model relates to a transportation equipment in the mining site specifically is a mine car self -actuating brake and speed control unit, including trigger device, controller, preceding brake lever, back brake lever, brake ware. Wherein trigger device sets up on the wheel of mine car one side, and when reaching certain speed in the mine car traveles, the centrifugal force that turning wheels produced triggers the trigger device action of fixing on the mine car wheel, and then makes the controller action, the closed -loop circular telegram, and the electro -magnet has magnetism, and the brake lever is tightened up around the control for the connection is moved at the brake ware of brake lever tip, reaches the effect of brake. When brake equipment vehicle travelling speed decline in ore deposit after operation a period, centrifugal force diminishes and makes trigger device break off, and the position is resumeed to the front and back brake lever under reset spring's effect, andthe mine car continues t
