Braking device with hydraulic disc brake for electric locomotive

The utility model provides a braking device with a hydraulic disc brake for an electric locomotive. The device comprises a hydraulic station and a braking device, wherein the hydraulic station is connected with a piston in the braking device by a hydraulic pipeline, a braking disc which is arranged in the braking device and fixed with wheels of the electric locomotive into a whole corresponds to the piston, the piston is driven by the hydraulic station to displace to compress or loosen the braking disc, and the braking and the braking release of the wheels are realized. By adoption of the device, an air braking system in the prior art is changed into the braking device with the hydraulic disc brake, the defects of high noise, high failure rate, environment pollution by compressor oil and the like existing in the air braking system are overcome, and the purposes of basically no noise, no pollution, low oil consumption and good braking are achieved.
