Abstract

The utility model relates to a clutch operating system for an automobile, particularly to an improved clutch operating system for an automobile. The utility model is characterized in that an exhaust hole of a clutch slave cylinder is provided with a check valve; the check valve formed by a valve body, a valve cap, a spring and a ball valve is provided with an oil pipe which is connected with an oil storage tank; the valve body is provided with a transverse through hole perpendicular to the axial direction of the valve body; and a through hole is formed in the center of the valve cap. In the utility model, since an exhaust oil path including the check valve is arranged in the original operating system, and the check valve has the effect of exhausting automatically, the improved structure fundamentally eliminates gas in the oil path system and ensures operation reliability of the clutch. The clutch operating system has reasonable structure and convenience, and is a beneficial improved design.

Description

Improved autoclutch maneuvering system
Technical field
The utility model relates to the clutch operating system of automobile, especially about a kind of improved autoclutch maneuvering system.
Background technology
The existing autoclutch oil gas operating system of Shi Yonging, mainly form by petrol storage tank, clutch master cylinder, clutch slave cylinder, exhaust bolt, adaptor union and oil pipe, for eliminating the gas in the oil piping system, be provided with deflation hole and twist at clutch slave cylinder and be connected to an exhaust bolt 8, screw this screw and carry out artificial exhaust with fitfull, lost efficacy or the generation fault to prevent that clutch system from handling, the formation scheme drawing of this system is seen accompanying drawing 3.In addition, when the vehicle ' process operates the clutch, the seal leakage of Chang Fashengyin oil connector, clutch master cylinder and wheel cylinder and the air admission oil piping system is arranged, secondly, the oil gas that air that clutch operating system fails to drain when refueling and power-transfer clutch in use produce.Owing to have gas in the oil circuit, in practical operation, easily cause the separation of power-transfer clutch not thorough, and therefore may produce the fault of power-transfer clutch.
At present, the clutch control mode of heavy duty truck generally adopts oil gas operating system, and it is light that this operating system has operation, and reliability is higher, general layout advantage easily.But in actual use, the oil circuit air inlet takes place easily, produce the fault that power-transfer clutch can not thoroughly separate.
The utility model content
In order to address this problem, the purpose of this utility model is, a kind of improved autoclutch maneuvering system is provided, and is that power-transfer clutch oil gas operating system is improved, increase thoroughly solves because the problem of the caused clutch control fault of oil circuit air inlet from exhaust system.
The technical scheme that the utility model technical solution problem is adopted is: a kind of improved autoclutch maneuvering system, comprise petrol storage tank, clutch master cylinder, adaptor union, oil pipe, clutch slave cylinder, the deflation hole that it is characterized in that clutch slave cylinder is provided with check valve, and check valve is provided with oil pipe and connects petrol storage tank; Check valve is made of valve body, valve plug, spring and ball valve, and valve body is provided with and its axial vertical cross through hole, and the center of valve plug is provided with through hole.
Press the autoclutch maneuvering system that this programme is implemented, owing in former maneuvering system, be provided with the exhaust oil circuit that comprises a check valve, this check valve has self-bleeding effect, and improved structure has fundamentally been eliminated the gas in the oil piping system and ensured the reliability of clutch control.The utility model is rational in infrastructure simple and direct, is a kind of useful improvement design.
Description of drawings
Fig. 1 is the maneuvering system scheme drawing of a kind of embodiment of the utility model;
Fig. 2 is the structure for amplifying scheme drawing of check valve 5 among Fig. 1;
Fig. 3 is the scheme drawing of existing clutch operating system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, be the improved autoclutch maneuvering system of the utility model, comprise petrol storage tank, clutch master cylinder, adaptor union, oil pipe, clutch slave cylinder, it is that deflation hole at clutch slave cylinder is provided with check valve 5, and check valve 5 is provided with oil pipe 3 and connects petrol storage tanks 2.Check valve is made of valve body 51, valve plug 52, spring 53 and ball valve 54 in the present embodiment, and valve body is provided with and its axial vertical cross through hole 510, and the center of valve plug 52 is provided with through hole 520.
Working process of the present utility model is such: oil pipe 3 is set connects the check valve 5 that exhaust is used, check valve is made of valve body 51, valve plug 52, spring 53 and valve ball 54, and the two ends of oil pipe 3 connect the central through hole 520 of check valve and the petrol storage tank 2 of clutch master cylinder respectively.When stepping on clutch pedal 1, a part of braking fluid enters oil pipe 3 from the set check valve 5 of clutch slave cylinder 7, at this moment, as in the power-transfer clutch oil circuit gas being arranged, these gases will be discharged in the oil pipe 3 through the through hole in the check valve 520, gas enters petrol storage tank 2 from oil pipe 3 and drains into atmosphere, thereby realizes the self-bleeding of power-transfer clutch oil circuit.After pedal of clutch unclamped, the oil of discharging in the system can add in the oil piping system from the cross through hole 510 the check valve 5 of the compensation orifice of clutch master cylinder 6 and clutch slave cylinder 7.In this oil piping system, what play a crucial role is check valve 5.The spring of check valve 5 is provided with certain precompressed compression, so that postpone closing of check valve 5, guarantee when power-transfer clutch is worked, but some braking fluid via through holes 520 drains in the power-transfer clutch petrol storage tank 2.
In the accompanying drawing 2, this check valve is installed in the deflation hole place of clutch slave cylinder 7, and when power-transfer clutch was worked, some braking fluid was discharged from through hole 520.When in the system air being arranged, because check valve 5 is arranged on the highest point of clutch slave cylinder 7, the gas in the clutch slave cylinder can be discharged through check valve.
The principle of work of native system is as follows: when using pedal of clutch, leading portion at the whole forced stroke of pedal of clutch, because the delayed-action of the check valve of installing on the clutch slave cylinder, part braking fluid is squeezed into clutch slave cylinder from clutch master cylinder, and by discharging in the check valve of being located at clutch slave cylinder.Because the shock damping action of check valve cross through hole, along with pedal of clutch continue step on, pressure in the clutch slave cylinder sharply increases, when the pressure reduction of unidirectional valve opening 511 ends during greater than the pressure of check valve spring 53, valve ball 511 is by pressure oil jack-up, check valve is by quick closedown, and oil circuit is in closed state in the clutch actuation system.At this moment, along with stepping on of pedal of clutch, the self-bleeding of power-transfer clutch oil circuit finishes, and clutch slave cylinder enters mode of operation.
Accompanying drawing 3 is scheme drawings of existing clutch operating system, and 8 among the figure is for being arranged at the exhaust bolt of clutch slave cylinder 7 deflation holes.
