Abstract
The utility model provides an exhaust screw used for a clutch strengthener of automobiles; the external structure thereof consists of a quick joint male plug, a regular hexagonal convex platform, a screw rod part, an O-shaped sealing ring concave trough and a thread part which are sequentially connected one after another; in the internal structure, an internal ventilation hole 5 is communicated with a needle-typed ventilation hole 7; the exhaust screw is mainly characterized in that: the exhaust screw is provided with the male plug structure of the quick joint; the needle hole at the front part inside the exhaust screw has openings at two sides; the exhaust screw adds the O-shaped sealing ring which is arranged inside the O-shaped sealing ring concave trough; the front surface of the O-shaped sealing ring of the exhaust screw is a thread structure while the rear surface thereof is the screw rod structure; the dustproof cap of the exhaust screw is sheathed on the quick joint; the rubber ring of the dustproof cap is sheathed on the screw rod of the exhaust screw. The exhaust screw is provided with the original exhaust function, and can fill clutch braking liquid in the hydraulic operation structure when the filling head of the filling equipment is made into the female socket structure of the quick joint and inserted into the male plug structure of the exhaust screw.
Description
Technical field
The utility model belongs to the auto parts and components field, in more detail, relates to the exhaust bolt on the automobile clutch booster and the improvement of associated components, makes it not only have degassing function, also has the pouring functions of adding.
Background technique
At present, at the clutch booster that especially on heavy-duty car, has generally used hydraulic control mechanism on the automobile.The fluid passage of a whole set of hydraulic control mechanism is made up of master cylinder, oil pipe, clutch booster assembly etc. in simple terms, and the pipe-line system of its composition seals.When to hydraulic control system filling clutch brake liquid, be to add near the liquid oil-storing cup that is positioned at the master cylinder, when clutch brake liquid when oil pipe flows to the clutch booster assembly of rear-most end, a part of residual air in the pipeline can be compressed in herein.For not influencing the separating effect of clutch, air need be got rid of.
The method of this kind filling brake fluid after each filling finishes, all needs to carry out special exhaust, method is back and forth to trample clutch pedal, and the gas compression in the pipeline liquid to the pipeline rear-most end, is unscrewed exhaust bolt then and carried out exhaust, after treating the air emptying, again exhaust bolt is tightened.This kind method wastes time and energy, and can take the clutch brake liquid of a part during exhaust out of, has both wasted resource, again befouling environment.
Summary of the invention
Because annotating from oil-storing cup, clutch brake liquid causes clutch booster assembly place trapped gas in order to overcome, and then the time-consuming and waste problem of resource that needs exhaust to cause, one of method is exactly that clutch brake liquid is annotated from the exhaust bolt of clutch booster assembly, liquid is flowed forward from the oil pipe rear-most end, the air in the pipe is discharged from oil-storing cup.This kind method can make the air in the pipeline discharge voluntarily, has simplified the deairing step when vehicle is adjusted, and is convenient to the adjustment and the maintenance of vehicle hydraulic pipeline mechanism, has improved efficient greatly.
The exhaust bolt that the utility model provides a kind of automobile clutch booster to use, the public plug structure that this product structure adopts rapid pipe joint can realize adding pouring functions, and can switch fast.Its internal structure is communicated by inner vent hole and pin type vent, the fluid passage when being filling, the gas channel when also being exhaust; Its external structure is linked to each other successively by rapid pipe joint public plug, regular hexagon boss, screw rod position, O RunddichtringO groove, screw thread position and constitutes, and the most important thing is to have the public plug structure of rapid pipe joint.The public plug structure of rapid pipe joint is Japanese joint or European joint.
Pin type vent is the both-side opening mode.O RunddichtringO groove is in order to install O RunddichtringO, leakage of oil when preventing to annotate.
The utility model can also comprise dust cap.The rubber ring set of dust cap is at the screw rod position, and dust cap is set on the rapid pipe joint public plug.Need open dust cap during filling.
Internal ventilation hole structure, pin type vent hole structure in order to the circulation of liquid, flow out in order to air when exhaust when filling.Exhaust bolt links to each other with the screw thread of clutch booster assembly by exhaust bolt, and closely cooperates to play by conical surface and clutch booster assembly and prevent that brake fluid from flowing out from oil pipe.
When in hydraulic oil pipe, still there is portion gas to exist for other reasons, when needing to discharge, then the utility model still can be realized exhaust, and method for exhausting adopts present existing conventional method, promptly back and forth tramples clutch pedal, the pipeline rear-most end is arrived in gas compression in the pipeline liquid, unscrew exhaust bolt then and carry out exhaust, treat the air emptying after, again exhaust bolt is tightened.
The beneficial effects of the utility model are, have changed dosing method, and the air in the oil pipe can smooth and easyly be discharged, and the workload when having alleviated the vehicle debugging has improved working efficiency, safeguards clean environment; The quick change plug that adopts switches in the time of can realizing annotating fast, especially is fit to use on the production line, satisfies the fast beat requirement of production line; Still kept simultaneously original degassing function.

Embodiment
Embodiment 1.With reference to the description of drawings specific embodiment of the utility model.
See figures.1.and.2, the exhaust bolt that a kind of automobile clutch booster described in the utility model is used, on the external structure, rapid pipe joint public plug 1, regular hexagon boss 2, screw rod position 6, O RunddichtringO groove 3, screw thread position 4 link to each other successively.The O RunddichtringO is installed in O RunddichtringO groove 3 places.Inner vent hole 5 and pin type vent 7 communicate, the fluid passage when being filling, the gas channel when also being exhaust.
Dust cap 8 installs to public plug 1 in the rapid pipe joint, and the rubber ring set on the dust cap 8 is to the screw rod 6 of exhaust bolt.Regular hexagon boss 2 with spanner insertion exhaust bolt is assemblied in exhaust bolt on the clutch booster assembly 9 by screw thread position 4, and the internal thread of screw thread position 4 and clutch booster assembly 9 matches.The conical surface of the front portion of assembling final vacuum screw and the end of the fluid passage in the clutch booster assembly fit tightly, and make the fluid passage in the clutch booster assembly be in closed state.
With reference to Fig. 3, the female plug seat that the pipeline end on of the present utility model and the filing provision the is described back filling process that is connected.
Take off dust cap 8 during filling, exhaust bolt is unscrewed several buttons, make the conical surface of front portion of exhaust bolt and the end of the fluid passage in the clutch booster assembly lighten the slit, and then the pin type vent 7 of fluid passage in the clutch booster assembly and exhaust bolt is in connected state, then the female plug seat 11 of charging line end is inserted in the rapid pipe joint on the public plug 1, starts filing provision 10 and annotate.Close filing provision 10 after the filling, exhaust bolt is tightened, pull up the female plug seat 11 of the pipeline end of filling, and dust cap 8 is enclosed within on the public plug 1 of rapid pipe joint.
