FIELD: mechanical engineering; mechanical vehicle brakes. ^ SUBSTANCE: proposed hydraulic braking device contains brake master cylinder and hydraulic brake booster accommodating hydraulic piston hermetically moving and assembled with slide fit. Said piston divides booster working space into front and rear chambers. In initial position, chambers are in communication and are filled with hydraulic brake fluid at high pressure, and when brakes are applied, line communicating the chamber is closed. Line communicating second chamber of booster with brake master cylinder opens and booster piston comes into motion. Braking device contains drain space connected with front chamber of booster and working space of brake master cylinder. ^ EFFECT: facilitated control of braking force and process of braking. ^ 7 cl, 3 dwg |
