Problems solved by technology
However, it is not easy to install the disk eddy current brake here. First, the wheel is hot-pressed on the axle, and the wheel must be removed to install the brake, which is so difficult that it is not feasible; secondly, if the Before the wheel is press-fitted on the axle, the disc brake is first assembled on the axle, which in turn will bring great inconvenience to the adjustment of the working clearance of the brake, maintenance and repair, and replacement

The invention discloses a combined type disc-shaped eddy-current brake applied to a high-speed train. The combined type disc-shaped eddy-current brake comprises an axle, a combined type stator, a sliding bearing and two combined type rotor discs, wherein the combined type stator is formed by connecting two semi-circular stators through bolts; the sliding bearing is formed by two bearing bushes with flanged peripheries; each combined type rotor disc is formed by connecting two semi-circular rotors through bolts; the combined type stator is mounted on the axle through the sliding bearing; the two combined type rotor discs are symmetrically mounted on the axle in a pressed manner relative to the combined type stator; and working clearances exist between working disc surfaces of the combined type rotor discs and the relative side surfaces of the combined type stator. The combined type disc-shaped eddy-current brake has the advantages of simple structure, high braking efficiency and good heat dissipation performance, is convenient to mount and can be flexibly combined with a disc-shaped friction brake, thereby improving the braking performance of the high-speed train.
Description
technical field [0001] The invention relates to an auxiliary braking device for trains, in particular to a combined disc-shaped eddy current brake applied to high-speed trains. Background technique [0002] The braking system of high-speed trains is very important to the reliability and safety of trains. With the rapid development of high-speed railways, the requirements for the performance of braking systems are getting higher and higher. In case of an accident, the shorter the emergency braking distance of a high-speed train, the safer the train will run. In addition, in order to improve the ride comfort, there are higher requirements for the control accuracy of the braking force. At present, the braking form of high-speed trains generally adopts a combination of multiple braking methods. Electric braking is used when running at high speed, and mechanical braking is used when reducing to low speed, so as to reduce the wear of brake discs, wheels and rails, and reduce noise...
