Abstract

The invention discloses a rail car controllable acceleration braking device, a rail car provided with the rail car controllable acceleration braking device, and a rail car controllable acceleration braking method. The controllable acceleration braking device of the rail car comprises a braking execution component, a force application control component, a power loss reset component, a control action unit, a braking transmission mechanism and an elastic connecting component. The braking action unit outputs linear displacement through the elastic connecting component, the power loss reset component continuously applies a braking control force to the braking execution component, the linear displacement provided by the force application part can balance the braking control force, and the braking execution component provides a linear braking force for the rail car under the action of a resultant force. The braking force provided by the braking execution component is controllable and can be linearly output, so that stable braking of the vehicle is achieved, the running stability of the vehicle is improved, and the purposes of improving the riding safety and comfort of the vehicle are achieved.

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...
