Title
(EN) NUMERICAL CONTROL HYDRAULIC BRAKING DEVICE
(FR) DISPOSITIF DE FREINAGE HYDRAULIQUE À COMMANDE NUMÉRIQUE
(ZH) 数控液压刹车装置
Abstract
(EN)
A numerical control hydraulic braking device, comprising a numerical control system, a hydraulic pump, a one-way oil outlet valve, a first conversion valve, a numerical control brake master cylinder oil separation valve, and a high-pressure oil storage barrel (168). The numerical control brake master cylinder oil separation valve comprises a master cylinder (101) and slave cylinders (108) having one-to-one correspondence to the number of vehicle brake slave cylinders; each slave cylinder (108) comprises an oil separation cylinder and a piston (121); the master cylinder (101) comprises a valve barrel, a valve core, and a valve core pull plate (105) used for connecting to a brake pull wire; a brake pull plate drives the valve core to rotate to a braking state; a valve core oil inlet (113) abuts and is communicated with a valve barrel oil inlet (104); the brake pull plate drives the valve core to rotate to a braking release state; the valve core oil inlet (113) abuts and is communicated with a valve barrel oil return port. According to the numerical control hydraulic braking device, a braking device is improved, a numerical control brake master cylinder oil separation valve structure is re-designed, so that the numerical control hydraulic braking device can completely replace the existing vehicle braking device, and increases the safety coefficient of driving safety and transport safety.
