Description
technical field [0001] The invention relates to a hydraulic braking device, in particular to a hydraulic braking device for a hydraulic transmission box. 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...
