Heat-dissipating electric braking device

The invention provides a heat-dissipating electric braking device, and relates to the technical field of braking equipment. The heat-dissipating electric braking device is characterized in that two sets of symmetrical and parallel main landing gears are arranged, and four same main landing gear airplane wheels are installed on each set of main landing gears and include two front main landing gear airplane wheels and two rear main landing gear airplane wheels. Gearboxes are connected to the inner sides of the main landing gears on the rear portion, and connected with main landing gear wheel shafts, bearing boxes are connected with the main landing gear wheel shafts, and the main landing gear wheel shafts are connected with the main landing gear airplane wheels. Direct-current generators are connected with braking resistors, the braking resistors are connected with heat dissipation air ducts, and cooling fins are arranged in the heat dissipation air ducts. The direct-current generators are connected with branch cables, the branch cables are connected with a branch box, and the branch box is connected to an electronic equipment compartment of an electronic compartment through a control cable. According to the heat-dissipating electric braking device, the taxiing distance of an aircraft can be reduced, the braking performance in the abnormal state can be additionally improved, and the safety of the aircraft in the landing stage can be improved.
