The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in the figure, this vacuum booster assembly that the BA valve is arranged, mainly comprise control cock assembly 3, servo piston 4, BA valve 5, reaction plate 14 and take-off lever 13, control cock assembly 3 inserts in servo piston 4, servo piston 4 is provided with dust protecting cap 1 with the port of control cock assembly 3 coupling ends, approaches in this port and is provided with filtering noise elimination circle 2.One end of control cock assembly 3 is provided with BA valve 5, the assembling that matches of power piston 22 in BA valve 5 and servo piston 4, BA valve 5 comprises sliding sleeve 21, sliding sleeve spring 16 and locking plate 20, sliding sleeve 21 is connected with control cock assembly 3 by locking plate 20, sliding sleeve 21 is connected by sliding spring 16 and power piston 22, between sliding sleeve 21 and power piston 22, is provided with O RunddichtringO 17.One end of power piston 22 is connected with take-off lever 13 by reaction plate 14, and control cock assembly 3 is provided with tune gap piece 15 near an end of reaction plate 14.The dynamic spring 12 of take-off lever 13 peripheral hardware, servo piston 4 is positioned at the cavity of fore shell 11 and back cover 8 formation, and back cover 8 is provided with rear sealing gland 6 with the interface of servo piston 4.Control cock assembly 3 is provided with vacuum valve port 18 and atmosphere valve port 19.Servo piston 4 is outer is provided with front diaphragm assembly 10, partition assembly 9 and rear film assembly 7 successively, and front diaphragm assembly 10 comprises front diaphragm and front diaphragm shell, and partition assembly 10 comprises shelf and sealing gland, and rear film assembly 10 comprises rear film and rear film shell.
Increase BA valve 5 at the vacuum booster control part, under the emergency state, when the vacuum booster push rod reaches a certain speed, (or control valve rod momentum reaches trigger condition), control valve rod in control cock assembly 3 impacts the locking plate 20 in BA valve 3, it is opened, sliding sleeve 21 ejects rapidly, then sliding sleeve 21 striking control valve leather circles, atmosphere valve port 19 is opened rapidly, and the vacuum booster back cavity enters air, makes the very large power of vacuum booster moment output, automobile and then the larger deceleration/decel of generation, shorten braking distance.During the vehicle normal brake application, there are BA valve vacuum booster input-output curve and conventional vacuum booster same; During emergency brake of vehicle, BA valve vacuum booster input-output curve High power output is arranged in conventional vacuum booster power output, thereby make vehicle obtain larger braking force.
