A novel braking device of a rail vehicle is characterized in that when the braking device is used for braking, the kinetic energy of the rail vehicle is used for driving a generator to generate electricity through a speed-up gearbox on a wheel pair; a rotary shaft of the generator and a pinion shaft in the gearbox are connected through a drum-shaped tooth type coupler; the electricity generated by the generator passes through a frequency converter capable of carrying out alternating current and direct current conversion and then is output to a flywheel battery, so that the kinetic energy is converted into the electricity which is then stored in the flywheel battery; when the rail vehicle is accelerated, the direct current stored in the flywheel battery is converted into alternating current through the frequency converter capable of carrying out alternating current and direct current conversion to drive a motor, the motor drives the wheel pair to accelerate through a reducing gearbox, and the electricity in the flywheel battery is converted into the kinetic energy of the vehicle; the generator serves as the motor during driving, and at the time, the speed-up gear box becomes the reducing gearbox.
Description
technical field [0001] The design of the invention is a new braking device for rail vehicles. When braking rail vehicles, the traditional method is to use mechanical friction braking devices or resistance braking devices, which convert the kinetic energy of the vehicle into heat energy and dissipate it. After the flywheel battery is used, when the rail vehicle brakes, the kinetic energy of the vehicle can be converted into electrical energy through the generator and stored in the flywheel battery. When the vehicle needs to accelerate, the electric energy stored in the flywheel battery can be accelerated by the motor to drive the wheelset. Spin to release. The new braking device fundamentally solves the problems of energy saving, environmental protection, reliability and maintenance and replacement of the braking system, and has the characteristics of simple structure, safety, reliability and energy saving. Background technique [0002] When braking a rail vehicle, the trad...
