Abstract

The invention discloses a hydraulic brake stator and a hydraulic brake. The hydraulic brake stator comprises a stator body and a plurality of stator blades arranged on the stator body, wherein an oilinlet hole and an oil drainage hole are formed in the stator; the oil inlet hole extends to the front surface of the stator from the back surface of the stator through the interiors of the stator blades; and the oil drainage hole is formed in the edge of the stator. The hydraulic brake stator and the hydraulic brake are capable of realizing rapid oil filling and oil drainage, high in braking response speed, and applicable to a high-speed vehicle; the brake is small, light in weight, and convenient to install; the brake is applicable to long-time continuous braking, and free from mechanical wear; the brake improves the safety of downhill running, and can realize a constant low speed during downhill; and the brake is low in noise, and high in continuous braking capacity.

Description

technical field [0001] The invention relates to a hydraulic brake device, in particular to a hydraulic brake stator and a hydraulic brake. Background technique [0002] Locomotives running in mountainous areas need to use brake shoes frequently in order to control the speed when going downhill. Long-term use will cause serious wear of the brake shoes and generate a lot of heat, which is very detrimental to the safe running of the rolling stock. In order to ensure For good braking performance, in addition to brake shoe braking, rolling stock also needs to be equipped with auxiliary braking methods. [0003] In addition to the need to equip the locomotive with an auxiliary braking method, for the sake of safety, the locomotive running downhill is required to be able to adjust the speed of the locomotive or maintain a constant low speed downhill, that is, the braking power can be adjusted steplessly according to the speed of the vehicle. [0004] At present, the commonly used ...
