Abstract
The utility model disclose a clutch booster, which comprises a cylinder assembly and a valve seat assembly which are mutually connected by a bolt, wherein the cylinder assembly comprises a cylinder, a piston, a piston rod, an air cavity, an air duct and a draw rod, and the valve seat assembly comprises a valve seat, an oil cavity and an air-inlet-outlet valve seat. An interrupted wall is arranged in the middle of an isolated cavity body of the air cavity and the oil cavity, which leads the oil cavity and the air cavity to be completely isolated, and high-pressure gas can not get into the oil cavity, thereby thoroughly avoiding the phenomena of failure gas blowby (internal drainage), and guaranteeing the reliability of use. And meanwhile, the clutch booster can achieve the set-resetting gas simulating of limited stroke when in shifting, can alarm before a friction plate is abraded to the boundary, and is particularly suitable for being used in clutch operating systems of heavy trucks, large buses and engineering machinery.
Description
Technical field
The utility model relates to the booster that a kind of heavy-duty car, motor bus and engineering machinery are used in clutch operating system.
Background technique
At present, employed clutch booster in the clutch operating system of domestic heavy-duty car, motor bus and engineering machinery, though adopted the booster (patent No. is that the utility model patent of ZL99252062.2 discloses a kind of like this automobile clutch booster) that has from functions such as adjust the play, the measurement degrees of wear, solved and stepped on the heavy problem of clutch pedal (gas power-assisted), but in use also there are some defectives in such clutch booster.As: idol has air cavity to cause inefficacy to oil pocket gas blowby (in let out), and friction disc wear does not have prior warning during to the limit, can not repeat when particularly shifting gears to guarantee to get gas power-assisted gearshift etc. after the separation, has brought inconvenience to use, uses very unreliable yet.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of oil gas two chambeies and isolates fully, limits resetting certainly of stroke in the time of can realizing shifting gears and get gas, can provide warning, simple in structure, service-strong clutch booster at friction disc wear to the limit.
For solving the problems of the technologies described above, the utility model clutch booster comprises cylinder assembly and valve seat assembly, link to each other with bolt each other, described cylinder assembly comprises cylinder, piston, piston rod, air cavity, air flue and rod assembly, described valve seat assembly comprises valve seat, oil pocket and intake and exhaust valve seat, be provided with a dilapidated walls in the middle of the isolated chambers of described air cavity and oil pocket, oil gas two chambeies are isolated fully.
Above-mentioned clutch booster, it also comprises warning device, and described warning device is located on the described valve seat, and it comprises alert rod, spring and Alarm contactor, and described Alarm contactor is located at the end of described alert rod, and described spring is located at the inboard of described Alarm contactor.
Above-mentioned clutch booster, it also comprises the shift valve assembly, described shift valve assembly links to each other with described valve seat, it comprises gearshift valve body, mobile valve, locking spring, pull bar and air intake valve, described pull bar adopts the pull bar of described cylinder assembly, and described locking spring is sheathed on described pull bar and is positioned on a section of described mobile valve.
Above-mentioned clutch booster, described piston comprises piston only, and the sidewall of described piston only is provided with piston apron groove, and the medial shaft wall of described piston apron groove and bottom cross wall are two parts that the thin plate side of described piston only forms along the back of riving.
Above-mentioned clutch booster is provided with four small column locating faces that are interrupted, are symmetrically distributed mutually in the pit of described cylinder head.
Above-mentioned clutch booster, described intake and exhaust valve seat is provided with the cylindrical screw seal groove of sealing.
The utility model is isolated between the air cavity of valve seat assembly and the oil pocket fully owing to adopted above-mentioned technical pattern, and pressurized gas can't escape in the oil pocket, thereby (in the let out) failure phenomenon of thoroughly having stopped gas blowby has guaranteed the reliability of using.Friction disc wear to the limit, Alarm contactor can be in the mileage of setting continuous alarm (sound, light), guarantee that vehicle can arrive the maintenance station as scheduled.The setting of shift valve can be carried out gearshift after clutch separation, guarantee the steady of gearshift, has protected synchronizer.Piston can adopt sheet stamping-periphery (extruding)-spinning process of riving, and technology is simple, and is easy to process, saves material, simple for structure, reasonable rigidity such as (stress surface) being close to, and is air tight.Be provided with the small column locating face of four interruption-symmetries in the cylinder head pit, solved the difficult problem that sheet stamping member pit (when pit depth approximates lamella thickness) can not be located.The garden post spiral seal groove of set sealing simplifies the structure on the intake and exhaust valve seat, guarantees the reliability of sealing.
