Technical background:

the meaning of the rail train in the text refers to a subway train, a high-speed train and a general name of the train, and the subway train and the high-speed train adopt an electric braking mode at present. When a subway train or a high-speed train brakes, a driving motor carried by the train is changed into a generator, the torque force on a wheel shaft is transmitted to a motor shaft through gear engagement to drive the motor to rotate together, the motor generates electricity to convert the kinetic energy of the train into electric energy, and the kinetic energy of the train is reduced, so that the train is decelerated to achieve the purpose of braking. The electricity generated by the motor is sent to the power grid for use by other trains. But the electricity generated by the motor can only be used by other trains nearby the train. If no train is in use nearby, the electricity cannot be used, can only be consumed through the vehicle-mounted resistor, is wasted, and generates a large amount of waste heat. When the speed of the train is reduced to below 8 kilometers per hour, the electric braking effect is poor due to low rotating speed, and the electric braking is not adopted. But the brake shoes are adopted to rub the wheels to brake the train, and the braking energy is changed into heat and is wasted. For the reasons, the electric brake regeneration rate is not high, the average regeneration rate of the brake energy is less than 50%, and for a train using an internal combustion engine, brake shoes and friction wheels are adopted in the braking process to brake the train, so that the brake energy is not recycled and is changed into heat.

The invention comprises the following steps:

the invention aims to provide a train braking device which can efficiently recycle and reuse braking energy, can recycle and reuse the braking energy under the condition that electric braking cannot be used and cannot regenerate the braking energy, namely, a subway train and a high-speed railway train which are braked have no other trains nearby to absorb regenerated electric energy, and can also recycle and reuse the braking energy of an internal combustion locomotive under the condition that the train runs at low speed. Realizing zero breakthrough of braking energy regeneration.
