During concrete enforcement, the gas servo-cylinder is provided with suitable piston in the chamber, and the mouth in gas servo-cylinder chamber is provided with cover plate, is provided with plunger and passes piston and cover plate, and plunger is fixedly connected on the piston.
During concrete enforcement, all-in-one-piece valve body is provided with suction port, air outlet and hydraulic fluid port, establish successively in the suction port place of described all-in-one-piece valve body air inlet seat, valve spring, valve, equalizing piston are housed, be arranged with equalizing piston spring on the equalizing piston, be provided with cavity in the equalizing piston, suction port communicates by cavity in the equalizing piston and air outlet.
Be provided with guide sleeve and little guide ring between the inner chamber of plunger and valve body.
Be provided with big guide ring between the inner chamber of piston and valve body.
Valve body is provided with mounting hole, and lining is housed in the hole, and the plunger end of stretching out cover plate is provided with screw.When car load assembles, only need mounting hole by valve body carry out hinged and screw plunger just connect can, quite convenient.
On the cover board be connected with the respirating tube interface.
Valve body is an aluminum alloy high pressure die casting valve body.
Owing to adopt all-in-one-piece valve body, saved attachment bolt and Sealing between the gentle servo-cylinder of hydraulic work cylinder, improved the rigidity of assembly, guaranteed the sealing reliability of assembly.
All-in-one-piece body cavity is divided into hydraulic work cylinder chamber and gas servo-cylinder chamber, hydraulic work cylinder chamber and gas servo-cylinder chamber just are equivalent to the gentle servo-cylinder of fully independent produced hydraulic work cylinder on the conventional clutch booster, thereby guaranteed the coaxality relation of two cylinder bodies better, improved the quality of product.And the integrated type valve body can adopt aluminum alloy high pressure die casting, and time processing is promptly plastic, has the advantage that processing is easy and cost is low.The left end of described valve body has designed a hinge needed mounting hole has been installed in addition, lining is housed in the hole, and on the plunger of right-hand member, be provided with screw, when car load assembles, only need mounting hole by the valve body left end carry out hinged and the screw thread plunger right-hand member just connect can, quite convenient.Integrated type clutch booster described in the utility model, also save attachment bolt and seal element between the gentle servo-cylinder of hydraulic work cylinder, made the product assembly structure compact more, made things convenient for the assembling of assembly, improve the rigidity of assembly, guaranteed the sealing reliability of assembly.
The beneficial effects of the utility model are: valve body adopts overall structure, have advantages such as compact structure, good rigidly, coaxality are good, assembly good airproof performance, prolonged the working life of clutch booster, in addition because used part is less, reduce cost, also be convenient to assembling.
Description of drawings
Below in conjunction with drawings and Examples model utility is further specified.
Fig. 1 is the utility model embodiment's a structural representation.
Among the figure: 1, guide sleeve 2, plunger 3, little guide ring 4, hydraulic fluid port 5, hydraulic work cylinder chamber 6, mounting hole 7, valve body 8, air outlet 9, equalizing piston 10, equalizing piston spring 11, valve 12, valve spring 13, air inlet seat 14, suction port 15, gas servo-cylinder chamber 16, piston 17, big guide ring 18, cover plate 19, screw 20, respirating tube interface
Embodiment
Among Fig. 1, a kind of integrated type clutch booster comprises valve body 7,5 gentle servo-cylinder chambeies 15, hydraulic work cylinder chamber, and valve body 11 is whole valve body, and valve body 7 forms for aluminum alloy high pressure die casting, and valve body 11 is provided with suction port 14, air outlet 8 and hydraulic fluid port 4.5 gentle servo-cylinder chambeies, 15 connections of hydraulic work cylinder chamber are located in the inner chamber of valve body 7.Be provided with suitable piston 16 in the gas servo-cylinder chamber 15, the mouth in gas servo-cylinder chamber 15 is provided with cover plate 18, is provided with plunger 2 and passes piston 16 and cover plate 18, and plunger 2 is fixedly connected on the piston 16.Be provided with guide sleeve 1 and little guide ring 3 between the inner chamber of plunger 2 and valve body 7.Be provided with big guide ring 17 between the inner chamber of piston 16 and valve body 7.Establish successively in suction port 14 places of valve body 7 air inlet seat 13, valve spring 12, valve 11, equalizing piston 10 are housed, be arranged with equalizing piston spring 12 on the equalizing piston 10, be provided with cavity in the equalizing piston 10, suction port 14 communicates by cavity and the air outlet 8 in the equalizing piston 10.Valve body 7 is provided with mounting hole 6, and lining is housed in the hole, and plunger 2 ends that stretch out cover plate 18 are provided with screw 19.On cover plate 18, be connected with respirating tube interface 20.
