Description
Technical field
The utility model relates to a kind of brake device for car, especially relates to a kind of electric booster braking device.
Background technology
Along with the raising of people to the requirement of vehicle safety, people are also improving constantly the requirement of brake device for car.Servo-unit in the existing brake device for car adopts vacuum booster mostly, and vacuum booster is the core component of vacuum servo servo braking system, is to utilize the vacuum of engine air inlet tube and the pressure reduction between the atmosphere to play the power-assisted effect.When engine starting, driving engine is taken the air of vacuum booster ante-chamber, back cavity away by vacuum hose, vacuum booster ante-chamber, back cavity communicate at this moment, all be vacuum, owing to do not step on brake pedal, vacuum valve is open mode at this moment, atmos-valve is closed condition at this moment, the ante-chamber back cavity communicates, and two chambeies do not have pressure reduction, and vacuum booster does not provide power-assisted; When stepping on brake pedal, vacuum valve cuts out earlier, ante-chamber back cavity pathway closure, along with the continuation reach of pedal, this moment, atmos-valve was opened, atmosphere enters back cavity through the atmosphere valve port, because this moment, ante-chamber still was a vacuum, pressure reduction appears in ante-chamber and back cavity, and the back cavity atmospheric pressure is greater than ante-chamber, the epithelium assembly promotes the piston body reach, and brake boost is provided.But existing this vacuum booster constitutes gas chamber by outer hull, has idle travel when gas enters cavity, and power-assisted size can not regulate effectively, causes in drag process medium sensitivity not highly, has certain potential safety hazard.Because vacuum booster front case and rear housing all are sheet metal component, riveted joint or roll extrusion link together then, and the power of being born on the vacuum booster acts on the housing of front and back, so the stressed rigidity of outer hull is bad all.
As notification number is a kind of vacuum booster of CN1576126, comprising: the servo-unit housing; Booster piston, this booster piston is contained in the servo-unit housing, so that the servo-unit enclosure interior is divided into anterior vacuum chamber and the rear operating chamber that links to each other with vacuum source; The valve rod body, this valve rod body is bearing on the rear wall of servo-unit housing slidably, so that be connected with booster piston; The input bar, this input bar can seesaw; The input return spring, this input return spring is along returning direction bias voltage input bar; Control cock, this control cock according to seesawing of this input bar and in conversion operations chamber and vacuum chamber and the atmosphere is communicated with, this input bar is arranged in the valve rod body, this control cock is introduced valve seat by atmosphere, vacuum introduces valve seat and the valve element constitutes, this atmosphere is introduced valve seat and is formed on the valve piston, this valve piston link is imported seesawing of bar and is moved, this vacuum is introduced valve seat and is connected with the valve rod body, move so that link seesawing of valve rod body, and this valve element carries out bias voltage by spring along the direction that makes this valve element place atmosphere to introduce on valve seat and the vacuum introducing valve seat, rupturing operation chamber and atmosphere and vacuum chamber is communicated with when this valve element places on described two valve seats, when atmosphere introducing valve seat is opened along with travelling forward of bar of input, make the operation chamber be communicated with, and when vacuum introducing valve seat is opened along with importing returning of bar, make the operation chamber be communicated with vacuum chamber with atmosphere; And counter-force mechanism, this counter-force mechanism is arranged in the valve rod body with input bar and is supported on slidably between the take-off lever on the servo-unit housing, and this counter-force mechanism will input to the manipulation input force of input bar and the combining ability of the thrust of the booster piston that produced by the bar pressure difference between operation chamber and vacuum chamber passes to take-off lever, wherein, valve piston be installed in counter-force mechanism, with input bar bonded assembly input piston on, therefore, valve piston can be with respect to input piston from being scheduled to retracted position to front slide; Between input piston and valve piston, be furnished with spring is set, be used for the valve piston bias voltage to retracted position; And between valve piston and valve rod body, be furnished with blocking device, so that in advance when the valve rod body travels forward the emergency braking of predetermined stroke or bigger stroke, make atmosphere introduce valve seat on the valve rod body to stay open state by being locked in the proal valve piston of input piston at input piston.Though no matter this patent is normal brake application or emergency braking, all eliminated the delay of atmosphere being introduced the operation chamber, and when emergency braking, can more early reach and remain on servo limit point, but the size of brake boost is automatically regulating as required, and there is idle travel in vacuum-assisted mode.
As notification number be: a kind of electric control vacuum booster of CN200967472, electric control vacuum booster provides a kind of artificial pedal brake pattern that both kept, satisfy the needs of operation of navigating mate normal brake application or emergency brake operations, can carry out the technical scheme of the electric control vacuum booster of brake operating again by autonomous cruise speed system; The utility model design-calculated electric control vacuum booster is made up of vacuum booster, pilot piping, electromagnetic valve etc., connects and can substitute artificial emergency braking under tyre break, situation such as crashproof with automatically controlled mode and autonomous cruise speed system; Also can be applicable to maintain safe distance, the autobrake of application scenario such as automatic backing.Though this patent has been set up intelligent autobrake pattern, but still can't avoid the idle travel that exists in the servo-unit, and power-assisted size automatically regulating as required.
