A rail car controllable acceleration braking device, a rail car equipped with the rail car controllable acceleration braking device, and a rail car controllable acceleration braking method. In the present invention, the controllable acceleration braking device for a rail vehicle includes a brake execution component, a force application control component, a power failure reset component, a control action unit, a brake transmission mechanism and an elastic connection component. The braking action unit outputs a linear displacement through the elastic connection part, and the power-off reset part continuously applies the braking control force to the brake execution part. The linear displacement provided by the force application part can balance the above-mentioned braking control force, and the brake execution The components provide a linear braking force to the rail car under the combined force described above. The braking force provided by the brake actuator is controllable and can be linearly output, so as to achieve stable braking of the vehicle, improve the stability of the vehicle operation, and achieve the purpose of improving the safety and comfort of the vehicle.
Description
technical field [0001] The invention relates to the technical field of rail car driving control, and more specifically, to a rail car, a controllable acceleration braking device for a rail car and a controllable acceleration braking method for a rail car. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. Among them, the most typical rail transit is a railway system composed of traditional trains and standard railways. With the advancement of science and technology, rail transit is gradually developing from the traditional "human control" to "intelligent control". [0003] In the intelligent rail transit system, the driving of the vehicle is mainly controlled by the intelligent control system, which mainly includes the following three types: acceleration control of the vehicle, cruise control of the vehicle and braking control of the vehicle. For the brake control of the ve...
