Description
Technical field
The present invention relates to a kind of hydraulic reinforcement brake controller of automobile, belong to the hydraulic braking system for automobile field of components.
Background technology
In the present hydraulic braking system for automobile both domestic and external, extensively adopt brake servo unit: as vacuum booster, Pneumatic booster, the power when these brake servo units consume automotive engine work.When automobile brake, send the brake pedal force that braking force can alleviate chaufeur, effect is better, but complex structure, volume are big, maintenance difficult, driving engine extinguishes and promptly loses assist function, and oil consumption, the more important thing is the anti-function of embracing of its no wheel.The present inventor applies for that the Chinese patent ZL200720078922.X that authorizes is entitled as " a kind of hydraulic booster composite braking valve for automobile " and has simple in structure, easily manufactured, can substitute vacuum booster, complicated but this valve arrangement still shows, volume is bigger, and Applicable scope is subjected to certain limitation.
Summary of the invention
The objective of the invention is provides a kind of hydraulic reinforcement brake controller of automobile at the deficiencies in the prior art, be characterized in increasing hydraulic coupling (pressure that promptly is higher than main pump output) behind this controller of brake fluid pressure oil process with the output of automobile brake main pump, transfer to the brake cylinder of wheel, increase hydraulic braking force, make automobile realize gradual braking.
Purpose of the present invention is realized by following technical measures
Hydraulic reinforcement brake controller of automobile
Cylinder body one end of hydraulic reinforcement brake controller of automobile is connected with the oil-feed cylinder head by second tightening seal washer, the cylinder body other end is connected with fuel-displaced cylinder head by first tightening seal washer, the charged piston bar is packaged in the cylinder body, the charged piston bar relies on retracing spring to press against oil-feed cylinder head place, in the big end of charged piston bar guiding valve and valve seat are housed, guiding valve relies on pressure spring that the push rod of guiding valve is pushed against the block place that is loaded in the oil-feed cylinder head, form clearance channel c between the push rod cross-sectional plane of guiding valve and the endoporus of valve seat, passage c and passage b, a and d are communicated with, and be connected conducting with the fuel-displaced cylinder head of the small end of charged piston bar, charged piston bar and valve seat interface adopt the sealing of O RunddichtringO, and the big end of charged piston bar and small end constitute integral body with seal ring and axle with the seal ring sealing by the hole.
The outside diameter D of charged piston bar
1Greater than end diameter D
2, the supercharging multiple
The push rod cross-sectional plane of guiding valve is circle or triangle.
The present invention has following advantage:
1, the brake fluid pressure oil of the brake main pump of hydraulic reinforcement brake controller of automobile output increases hydraulic coupling behind this controller, and is higher than main pump output hydraulic coupling, and transfers to the brake cylinder of wheel, increases hydraulic braking force, makes the braking of automobile balance;
2, because the operation pressure of the required automobile main pump of hydraulic reinforcement brake controller of automobile is lower, and the brake pedal force that navigating mate applies is also less, can cancel or the existing automobile of partial cancellation in the additional brake servo-unit, simplified brake system of car.

The specific embodiment
Below by embodiment the present invention is carried out concrete description; be necessary to be pointed out that at this present embodiment only is used for the present invention is further specified; can not be interpreted as limiting the scope of the invention, the person skilled in the art in this field can make some nonessential improvement and adjustment according to the content of the invention described above.
Embodiment
The outside diameter D of charged piston bar 7
1Greater than end diameter D
2, the supercharging multiple
The push rod cross-sectional plane of guiding valve 8 is circle or triangle.
The present invention is achieved in that
The hydraulic reinforcement brake controller of automobile glancing impact, automobile brake main pump output brake fluid pressure oil, via controller oil-feed cylinder head 14, passage a in the link stopper 12, valve seat 11 breach b, passage c that the push rod of guiding valve 8 and valve seat are 11 and the passage d in the charged piston bar 7 flow to car (preceding) wheel brake cylinder from fuel-displaced cylinder head 1, make wheel begin braking.Along with brake fluid pressure raises, act on thrust (because the D at charged piston bar two ends
1＞D
2) unequal, the charged piston bar is under the effect of big end thrust, overcome retracing spring 5 and little end resistance, the charged piston bar begins to move to small end, in moving, the push rod of guiding valve partly leaves link stopper 12, under the effect of pressure spring 6, make the step end face of guiding valve press to valve seat automatically, closing passage c, cut off passage d and b, sealing charged piston bar small end to car (preceding) is taken turns the brake fluid pressure oil between the brake cylinder, and in the charged piston bar moved continuously, the braking liquid that compresses in this enclosed cavity made brake fluid pressure rising in car (preceding) the wheel brake cylinder, its supercharging multiple i depends on the duplicate ratio of charged piston bar two ends diameter, promptly
Increase braking force, realize the braking of car (preceding) wheel.After end of braking, the automobile brake main pump resets, under the effect of retracing spring 5, charged piston bar 7 is drawn close to oil-feed cylinder head 14 directions, and the big distolateral braking liquid of discharge flows back to the automobile brake main pump.Because the charged piston bar is by enterprising oil cylinder head, the push rod of guiding valve 8 is gone up on link stopper 12 tops in the cylinder head, make lift off a seat 11 valve port of guiding valve 8 compression springs 6, guiding valve 8 step end faces, open passage c, communication passage d and b, oil return by car (preceding) wheel brake cylinder can flow back into the automobile brake main pump through passage d, c, b, a by fuel-displaced cylinder head 1, for braking next time is communicated with oil circuit.
