Problems solved by technology

Although the existing eddy current rail braking system adopted by ICE3 uses pressure release and lowering to ensure that the air cylinder operates when the air system fails, when the circuit fails, the loss of excitation will directly lead to the loss of braking force
In addition, when the power supply is cut off when the train is parked, the natural eddy current braking system cannot work

The abrasion plate comprises a metal base material and a nonmetal base material, a part of the surfaces of the metal base material and the nonmetal base material are combined together, the nonmetal base material is made of a polymer material, the volume ratio of the metal base material to the polymer base material is (4:1)-(3:2). The invention further provides a manufacturing method of the abrasion plate, the manufacturing method comprises the steps that prefabricating of the metal base material, machining of the metalbase material, hole-forming corrosion of the contact surface, injection molding of the nonmetal base material to the contact surface, and forming machining of the abrasion plate. The invention further provides a vortex track braking system provided with the abrasion plate. The abrasion plate for the vortex track braking system is designed, and the abrasion plate can be stored between the brakingsystem and a track to improve the braking capacity of the system through the material structure of the abrasion plate.

Description

technical field [0001] The invention relates to components of a rail braking system, in particular to a wear plate for an eddy current rail braking system, a system and a manufacturing method thereof. Background technique [0002] The shortage of railway transport capacity has become one of the main contradictions restricting the development of my country's economic construction. Due to its advantages of large transportation capacity, safety and comfort, all-weather transportation and sustainability, high-speed railway has become the basic trend of railway development and the basic guarantee for national modernization. According to the "Medium and Long-Term Railway Network Planning", the construction mileage of my country's high-speed railway will reach 18,000 kilometers in 2020. [0003] Braking technology is one of the nine key technologies of high-speed trains and is the "protector of life". During the braking process, the braking power is proportional to the cube of th...
