Description
Technical field
The present invention relates to a kind of automobile oil mass control to realize the operating device of speed limit, specifically a kind of automatic clutch is handled the speed limited valve of oil circuit.
Background technique
As automobile product clutch control system, separating with engaging at a slow speed fast is a basic demand, for realizing this purpose, the general means that increased trimmer valve in clutch manipulation oil circuit that adopt of domestic car solve problem, this method can only reduce pressure fluctuation, prevent the clutch pedal vibration, but do not regulate the effect of clutch engagement.
Summary of the invention
The technical problem to be solved in the present invention, provide a kind of automatic clutch and handle the speed limited valve of oil circuit, can adjust clutch engagement, improve the travelling comfort of taking, pause and transition in rhythm or melody sense when preventing to shift gears, because the too fast vehicle that causes of clutch engagement is flame-out, the present invention is simple in structure when preventing to start to walk simultaneously, with low cost, adopt the ready-packaged joint structure easy for installation.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of automatic clutch is handled the speed limited valve of oil circuit, comprises the valve body, spool and the valve seat that are coaxially set, and the main body of described spool is cylindric, has radially depression and the bypass oil duct of extension vertically in shaft;
Described valve seat is the pipe shape, and tube chamber is a central oil passage, and the internal diameter of valve seat is less than the footpath, the end of spool bypass oil duct; When spool and valve seat axially contact when stacked, the bypass oil duct of valve and valve core chamber is by shutoff fully;
Valve body comprises the 3 stops central stepped that the aperture is gradually big, and the thinnest place of leading portion of central stepped is an oil duct, and the aperture in stage casing and the outer radius of spool are complementary, and axial height is greater than the spool height, and the aperture of back segment and the external diameter of valve seat are complementary.
More than be basic structure of the present invention, it is connected between the master cylinder and clutch release slave cylinder of clutch control system in use, and when stepping on clutch pedal, oil pressure backs down spool, and fluid enters the clutch wheel cylinder by central oil passage and bypass oil duct, realizes separating fast; When unclamping clutch pedal, oil pressure is pressed to valve seat with spool, and the bypass oil duct is shut, and fluid can only enter the clutch master cylinder by central oil passage, realizes engaging at a slow speed.
As optimization of the present invention, the radial structure of described spool is that the edge is curved, " hollow ten " word shape of center band central oil passage, and radial cross section is the shape of smooth transition, and its bypass oil duct has four.
Such structure has guaranteed the quick separation of clutch and the effect that engages at a slow speed, and this is the core of this speed limited valve.
As another kind of optimization of the present invention, described central oil passage is a damping hole.
Central oil passage is the minor diameter damping hole, and only there is φ 1.325mm in the aperture, can realize the joint at a slow speed of speed limited valve.(aperture is set to φ 1.32-1.35 mm according to the difference of vehicle herein)
Owing to adopted above-mentioned technological scheme, the invention technological progress is: this product can be adjusted the engaging speed of clutch by hydraulic pressure, improve the travelling comfort of taking, pause and transition in rhythm or melody sense when preventing to shift gears, cause vehicle flame-out owing to clutch engagement is too fast when preventing to start to walk simultaneously, the present invention is simple in structure, and is with low cost, adopts the ready-packaged joint structure easy for installation.The present invention is fit to be installed between the master cylinder and clutch release slave cylinder of automatic clutch control system, to adjust the separation and the engaging speed of on-off control mechanism.
The present invention is described in further detail below in conjunction with Figure of description and specific embodiment.

Embodiment
Embodiment
Figure 1 shows that a kind of speed limited valve 10 of automatic clutch manipulation oil circuit, comprise the valve body 1, the spool 2 and valve seat 3 that are coaxially set, wherein spool 2 has central oil passage 8, and this central oil passage 8 is a damping hole.
As Fig. 3 and shown in Figure 6, spool 2 radial structures are that the edge is curved, " hollow ten " word shape of center band central oil passage 8, have four bypass oil ducts 9.The structure of spool 2 is equivalent to the shaft of cylindrical body is offered four uniform radial depressions, and the bypass oil duct 9 that extends vertically, its radial cross section is the shape that is become after the smooth transition, the center of radial cross section porose (shape in this hole is the radial cross section shape of central oil passage 8).
As shown in Figure 4, valve seat 3 is the pipe shape, and tube chamber is an oil duct 8, and the internal diameter of valve seat 3 is less than the footpath, the end of the bypass oil duct of spool 1.When spool 2 and valve seat 3 axially contact when stacked, four bypass oil ducts 9 of spool 2 are by shutoff fully.
As shown in Figure 2, valve body 1 comprises the multi-section type central stepped that the aperture is gradually big, and the thinnest place of leading portion of central stepped is an oil duct, and the aperture of middle inferior thin segment and the outer radius of spool 2 are complementary, axial height is greater than the height of spool 1, and the aperture of back segment cooperates with the crest clearance of valve seat 3.
With reference to figure 5, this product is series between the master cylinder 5 and clutch release slave cylinder 6 of clutch operating device during use, when the driver steps on foot treadle 4, promote the piston of master cylinder 5, produce oil pressure, oil pressure backs down spool 2, fluid is by central oil passage 8 and bypass oil duct 9, this oil pressure piston in the cylinder 6 that pushes the work forward, and clutch release slave cylinder 6 pistons promote the disengaging yoke rotation by push rod, drive release bearing 7 motions, thereby realize that clutch separates fast; When unclamping clutch pedal 4, oil pressure is pressed to valve seat 3 with spool 2, and bypass oil duct 9 is shut, and fluid can only enter the clutch master cylinder by central oil passage 8, realizes engaging at a slow speed.
