Description
One, technical field:
The utility model relates to a kind of automobile clutch, particularly a kind of clutch smooth and steady combination apparatus.
Two, background technique:
At car engine, starting, gearshift and when stopping, the joint of all can't do without clutch with separate, often have because of clutch pedal discharges too fastly, it is not steady to make it combination, causes the generation of rushing car even flame-out phenomenon, particularly beginner more very.So not only accelerated the wearing and tearing of clutch facing, caused decrease the morning of transmission system, and drive dysaesthesia.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provide a kind of control gear that can make the clutch smooth and steady combination, to reach gentle start, smooth lifting shelves, reduce component wear, the clutch smooth and steady combination apparatus that prolongs its working life.
Its technological scheme is: mainly be made of piston rod, last hydraulic pressure cavity, annular oil cavity, throttle orifice, oilhole, piston, cylinder body, lower hydraulic pressure chamber, undersetting; The fluid cylinder lid is installed at the cylinder body top, and the inner chamber of cylinder body is divided into hydraulic pressure cavity and lower hydraulic pressure chamber by piston, is provided with hydraulic oil in last hydraulic pressure cavity and the lower hydraulic pressure chamber; The lower end fixed piston of piston rod has annular oil cavity, oilhole and throttle orifice on the piston, spring seat is fixed in the piston rod upper end, and spring and oil pocket sealing cover can slide on piston rod, and by oil pocket sealing cover sealing annular oil cavity.
The quantity of the annular oil cavity on the described piston, oilhole and throttle orifice is more than one, and wherein, the diameter of annular oil cavity is greater than the diameter of oilhole, and described throttle orifice is located at the outside of annular oil cavity, keeps being communicated with oilhole always.
Hydraulic oil in the described cylinder body generally adds to cylinder body upper end 75%～80%.
Be provided with " O " RunddichtringO B between the inner chamber of described piston and cylinder body.
The beneficial effects of the utility model are: this device has been simplified the automobile operation complexity, has alleviated driver's labor intensity; And simple in structure, volume is little, easy accessibility; Mainly select plastic materials for use, easy to manufacture, cost is low, is easy to promote.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: 1. piston rod; 2. " O " RunddichtringO A; 3. fluid cylinder covers; 4. sealing gasket; 5. go up hydraulic pressure cavity; 6. spring seat; 7. spring; 8. oil pocket sealing cover; 9. annular oil cavity; 10. throttle orifice; " 11. O " RunddichtringO B; 12. oilhole; 13. piston; 14. cylinder body; 15. lower hydraulic pressure chamber; 16. undersetting.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model is achieved like this, it mainly is made of piston rod 1, last hydraulic pressure cavity 5, annular oil cavity 9, throttle orifice 10, oilhole 12, piston 13, cylinder body 14, lower hydraulic pressure chamber 15, undersetting 16 etc.; Cylinder body 14 interior hydraulic oil liquid volume addeds generally add to cylinder body 14 upper ends 75%～80% and are advisable, fluid cylinder lid 3 is installed in cylinder body 14 tops, by " O " RunddichtringO A and sealing gasket 4 sealings, spring seat 6 is fixed on the piston rod 1, and spring 7 and oil pocket sealing cover 8 can slide on piston rod 1; Piston 13 is fixed on the piston rod 1, seal by " O " RunddichtringO B11, annular oil cavity 9 is arranged on it, oilhole 12 and throttle orifice 10, oil pocket sealing cover 8 and piston 13 contact width a, b generally gets (1～2.5) mm, " O " RunddichtringO B (11) will go up hydraulic pressure cavity 5 and separate with lower hydraulic pressure chamber 15, " O " RunddichtringO A (2), B (11) and spring 7 selection standard spares, remaining part can be selected plastic materials for use, oil resistant and not corrosion, annular oil cavity 9 helps sealing and processing throttle orifice 10, the diameter of oilhole 12 and quantity are determined according to the diameter of piston 13, be generally (2～6) individual hole, its diameter is 1/6～1/10 of piston 13 diameters, and the diameter of throttle orifice 10 and quantity determines according to vehicle, be generally (1～5) individual, its diameter is (0.8～3) mm, spring 7 elastic force are unsuitable excessive, get 3%～7% of clutch pedal lever elastic force, in order to avoid increase the clutch pedal pedal force.
This device piston rod 1 is connected with the car clutch pedal lever, and the lower end is fixed on the car inner bottom plate.When driver's let slip the clutch, it is descending to promote piston rod 1, piston 13 is descending thereupon, hydraulic oil backs down oil pocket sealing cover 8 through oilhole 12, annular oil cavity 9 and enters hydraulic pressure cavity 5 in the lower hydraulic pressure chamber 15, throttle orifice 10 also has backflow, annular oil cavity 9 and oilhole 12 areas are big, and resistance is little, and pedal can be descending smoothly.When release the clutch pedal, piston rod 1, piston 13 are up under the drive of clutch pedal lever, oil pocket sealing cover 8 is under the effect of spring 7 and epicoele hydraulic oil, closed ring oil pocket 9, only there are throttle orifice 10 a small amount of oil returns to play throttling action, piston rod 1 slowly rises, thereby makes the smooth-going combination of clutch, so finishes a circulation.
