Abstract
The invention relates to a hydraulic pump buffer valve of an automobile clutch. The hydraulic pump buffer valve comprises a valve body (1) and a bracket (2), wherein an inlet pipe (3), an outlet pipe (4) and a buffer region (5) are arranged on the valve body (1); the inlet pipe (3) and the outlet pipe (4) are communicated through the buffer region (5); the buffer region (5) is provided with a diaphragm (6) which isolates the buffer region (5) from the outside; the inlet pipe (3) is connected with a pressure cavity of a master cylinder of a hydraulic clutch system; and the outlet pipe (4) is connected with a pressure cavity of a working cylinder of the hydraulic clutch system. The hydraulic pump buffer valve has the advantages of convenience for installation and use, high sealing performance, long service life and the like, and the problem of pressure fluctuation of a conventional clutch system is solved.
Description
Technical field
The invention belongs to the oil hydraulic pump buffering field of automobile clutch, particularly relate to a kind of oil hydraulic pump trimmer valve of automobile clutch.
Background technique
At present, the hydraulic system of known automobile clutch comprises: master cylinder, clutch release slave cylinder and connected pipes.
Adopt the hydraulic system of the automobile clutch of above-mentioned form, at SUV, diesel-oil vehicle larger defective is arranged: motor is the vibration of its bent axle particularly, can be by parts such as friction clutch, release bearing, disengaging yoke and clutch release slave cylinders, be sent to the hydraulic system between clutch release slave cylinder and the master cylinder, vibration is propagated in described hydraulic system with the form of pressure surge.The driver is felt as vibration at the clutch pedal place with pressure surge." pinching " phenomenon that generation is commonly called as has reduced the travelling comfort of driving.
For fear of the generation of above-mentioned phenomenon, between the hyperbaric chamber of the hydraulic system master cylinder of automobile clutch, clutch release slave cylinder, increase a trimmer valve, by pressure surge in the trimmer valve absorption system.
Summary of the invention
Technical problem to be solved by this invention provides a kind of oil hydraulic pump trimmer valve of automobile clutch, overcomes clutch system and is in operation and produces the defective of pressure surge.
The technical solution adopted for the present invention to solve the technical problems is: the oil hydraulic pump trimmer valve that a kind of automobile clutch is provided, comprise valve body and support, inlet pipe is arranged on the described valve body, go out pipe and buffer area, described inlet pipe and go out pipe and be communicated with respectively by buffer area, described buffer area is equipped with diaphragm buffer area is hedged off from the outer world, described inlet pipe connects the master cylinder pressure chamber of hydraulic pressure clutch system, goes out the pressure chamber that pipe connects the clutch release slave cylinder of hydraulic pressure clutch system.
Seal with seal ring between described diaphragm and the buffer area.
Described valve body is rack-mount with bolt, and described support is pressed on diaphragm in the valve body buffer area by Steel Cable Baffle Ring.
Described inlet pipe is equipped with the cone seal head, seals with O type circle between described cone seal head and the inlet pipe.
Described valve body is made by macromolecular material.
The pressure surge that produces in hydraulic work system flows in the trimmer valve with certain amplitude, diaphragm, seal ring, the meeting of Steel Cable Baffle Ring elastomeric material are owing to buoyancy effect is out of shape, in the case, diaphragm at the gas volume of texturing zone with compressed, so that hydraulic system is carried out limited expansion in the scope of trimmer valve, this can cause pressure amplitude to produce " decompression ".The buoyancy effect of simultaneous buffering valve elastic material and the gas volume of compression are dropping to when the pressure surge amplitude in the system when being lower than predetermined value, will automatically revert to its form originally.
Beneficial effect
The invention has the advantages that, solved the problem of traditional clutch system pressure surge, and obtained the beneficial effects such as easy to install, good airproof performance, long service life.The valve body of simultaneous buffering valve adopts plastic materials, uses O-ring seals and cone seal head and connected pipes to adopt traditional conical surface seal, so that trimmer valve is with the reliability of light and traditional conical surface seal of plastics.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, a kind of oil hydraulic pump trimmer valve of automobile clutch, comprise valve body 1 and support 2, inlet pipe 3 is arranged on the described valve body 1, go out pipe 4 and buffer area 5, described inlet pipe 3 and go out pipe 4 and be communicated with respectively by buffer area 5, described buffer area 5 is equipped with diaphragm 6 buffer area 5 is hedged off from the outer world, and described inlet pipe 3 connects the master cylinder pressure chamber of hydraulic pressure clutch system, goes out the pressure chamber that pipe 4 connects the clutch release slave cylinder of hydraulic pressure clutch system.
Seal with seal ring 7 between described diaphragm 6 and the buffer area 5.
Described valve body 1 usefulness bolt is installed on the support 2, and described support 2 is pressed on diaphragm 6 in valve body 1 buffer area 5 by Steel Cable Baffle Ring 8.
Described inlet pipe 3 is equipped with cone seal head 9, seals with O type circle between described cone seal head 9 and the inlet pipe 3.
Described valve body 1 is made by macromolecular material.
In actual use, seal ring 7, diaphragm 6 and Steel Cable Baffle Ring 8 form the capacity reception cavities with the buffer area 5 of valve body 1, and by bolton on support 2.Diaphragm 6, seal ring 7, Steel Cable Baffle Ring 8 adopts elastic materials, can produce distortion under the impact of pressure wave, thereby the Absorbing hydraulic pulsation wave-amplitude reaches the purpose of " absorbing ".When hydraulic oil flows into trimmer valve with the direction that illustrates arrow, fluctuation fluid with certain amplitude can directly impact on diaphragm 6, at this moment diaphragm 6, seal ring 7, the meeting of Steel Cable Baffle Ring 8 elastomeric material are owing to buoyancy effect is out of shape, gas volume in the capacity reception cavity of support 2 and valve body 1 composition is with compressed simultaneously, so that hydraulic system is carried out limited expansion in the scope of trimmer valve, produce " decompression " effect in the hydraulic system.And drop to when being lower than predetermined value when the pressure surge amplitude of gas volume in system of the buoyancy effect of trimmer valve elastic material and compression, will automatically revert to its form originally.
