Description

technical field [0001] The invention relates to the technical field of high-speed train braking, in particular to a high-speed train wind resistance braking energy conversion device and a high-speed train. Background technique [0002] At present, the braking method commonly used in high-speed EMUs is adhesive braking, that is, the braking force is applied to the vehicle by the rail through the wheel-rail rolling contact. During sticking braking, the braking force depends on the coefficient of adhesion between the wheel and rail, and the coefficient of adhesion decreases with the increase of train speed. [0003] Wind resistance braking is to increase the aerodynamic resistance by using the wings deployed at the corresponding positions of the train carriages to generate braking force. This braking method makes full use of wind energy, a clean, natural and environmentally friendly energy source. Moreover, this braking method has neither Wear parts, and no frictional heat, so...
