Except purpose described above, feature and advantage, the present invention also has other purpose, feature and advantage.Below with reference to accompanying drawings, the present invention is further detailed explanation.
Description of drawings
Accompanying drawing is used to provide a further understanding of the present invention, consists of the application's a part, and illustrative examples of the present invention and explanation thereof are used for explaining the present invention, do not consist of improper restriction of the present invention.In the accompanying drawings:
Fig. 1 is the scheme of installation of the preferred embodiment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
When adding brake noise in order to solve to the clutch system of vehicle, operating process is loaded down with trivial details, the technical matters that cost of labor is high, the clutch system oiling method that the invention provides a kind of clutch system refueling unit and adopt this device to refuel.Wherein, clutch system refueling unit can be independent of the clutch system of vehicle and use separately, can be in for the Detroit automation of vehicle interpolation braking liquid repeated usage.
Fig. 1 is the scheme of installation of the preferred embodiment of the present invention, below in conjunction with Fig. 1, clutch system refueling unit provided by the present invention and method is described in detail.
Generally include clutch booster 3, clutch master cylinder 2, clutch oil pot 1 in the existing vehicle clutch system, be interconnected by pipeline between the three, generally be provided with exhaust joint at clutch booster 3, topping up device of the present invention just can be realized by this exhaust joint the process of exhaust and oiling.In order to realize the purpose of labor savings, as a preferred embodiment, device of the present invention at first adopt vacuum pump 11 with clutch booster 3, clutch master cylinder 2, clutch oil pot 1 and between pipeline in air find time, make its inner vacuum that forms, next recycle the negative pressure of vacuum principle, with Fuel Tanking Unit, specifically, be exactly brake noise suction clutch booster 3, the clutch master cylinder 2 in the brake noise storage kettle 12, and in the clutch oil pot 1.Like this, just do not need a people to step on clutch pedal, another person carries out the complex operations process of exhaust, as long as people operates and just can realize making the clutch system exhaust and to the process of wherein adding brake noise.
Preferably, topping up device of the present invention can have a movable interface, this movable interface can be a quick connector 4, and this quick connector 4 can adopt the known product of supplying on the market, and its size and material can be selected according to actual needs.Vacuum pump 11 links to each other with this quick connector 4 with oil circuit 13 by gas circuit 8 respectively with brake noise storage kettle 12, then is flexibly connected by the exhaust joint of this quick connector 4 with clutch booster 3.Like this, just can make topping up device of the present invention be independent of the clutch system of vehicle, can reuse, improve service efficiency.
In order to simplify the pipeline structure of topping up device of the present invention, and the reliability of assurance pipeline connection, oil circuit is separated with gas circuit, and quick connector 4 can connect a T-pipe joint 5, and vacuum pump 11 can link to each other with exhaust joint by this T-pipe joint 5 respectively with brake noise storage kettle 12.
Better for the controllability that makes exhaust and refueling process, be provided with the first ball valve 7 in gas circuit 8, this first ball valve 7 can be used for the gas break-make on the control gas circuit 8; Be provided with the second ball valve 6 on the oil circuit 13, this ball valve can be used for oil circuit control 13 oil cans add unlatching from brake noise to clutch system and interruption.
In order to detect the sealing situation of clutch system, the situation of leakage of oil occurs when avoiding oil-filled, pressure-detecting device 9 can also be set on gas circuit 8, this pressure-detecting device 9 can be a compression indicator, when vacuum pump 11 clutch booster 3 of finding time, air in clutch master cylinder 2 and clutch oil pot 1 and the pipeline between them forms after the vacuum, because gas circuit 8 is in connected state with above-mentioned three arrangement of clutch, also be in the gas circuit 8 with the state of pressing, form after the vacuum, by the air pressure in the compression indicator monitoring gas circuit 8, if air pressure fluctuates, can judge that then clutch system has the position of gas leakage, illustrate that the sealing property of clutch system can not reach the degree that can add brake noise, then can temporarily in clutch system, not add brake noise, treat clutch system is overhauled or changed after the parts, guarantee that clutch system is in after the sealing state, add brake noise to it again, like this, just can avoid the waste of brake noise, increase work efficiency, save cost.
In order to prevent that oil or aqueous vapor in oil circuit 13 or the clutch system from entering into vacuum pump 11, improve the service life of vacuum pump 11, a fil 10 can also be set in gas circuit 8.
The condition of service of this device is as follows: at first the exhaust joint of quick connector 4 with clutch booster 3 is connected, clutch system is communicated with this device; Then open the first ball valve 7, close the second ball valve 6, make that gas circuit 8 is opened, oil circuit 13 is closed; Open vacuum pump 11, close vacuum pump 11 after air is found time, static a period of time is by the sealing property of compression indicator detection clutch system; If clutch system favorable sealing property then close the first ball valve 7 is opened the second ball valve 6, the brake noise of brake noise being stored in the kettle 12 by the negative pressure of vacuum in the pipeline sucks in the clutch system.After reaching the appropriate location, the brake noise in the clutch oil pot 1 closes the second ball valve 6; Tighten at last the bleeder screw of clutch booster 3, finish the process of adding brake noise.Fil 10 in this device is for filtering profit, prolonging the service life of vacuum pump.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
