Embodiment
With reference to Fig. 1-Fig. 4, of the present utility model pair of chamber hydraulic braking master cylinder entirety is a cylinder body 1, is provided with two side by side liquid chamber 2 in cylinder body 1, and liquid chamber 2 size shape is identical. Being provided with the piston 4 that front end is connected with pull bar 3 in liquid chamber 2, pull bar 3 and piston 4 can move in liquid chamber 2.
The front end of liquid chamber 2 is provided with oil-in 5, is provided with oil outlet 11 in the side of liquid chamber 2. Oil-in 5 place is provided with valve seat 6, is provided with the back-up ring 7 of movable closed oil-in 5 in valve seat 6, and back-up ring 7 general elastomeric material is made. The front end of pull bar 3 is fixed with back-up ring 7 through valve seat 6 and is connected with valve seat 6 by pull bar spring 16, on pull bar 3, cover has return spring 8, one end of return spring 8 is connected with valve seat 6, the other end is connected with the spring support 9 being fixed on piston 4, the rear end of piston 4 is connected with push rod 10, and push rod 10 passes from the rear end of liquid chamber 2 and is connected with pedal. Time static, piston 4 returns to original position under the effect of return spring 8, due to the reset of return spring 8, has driven pull bar 3 and spring support 9 to move, and back-up ring 7 moves out from the front end of liquid chamber 2, opens oil-in 5, and hydraulic efficiency oil flows in liquid chamber 2 from oil-in 5. When pin steps on pedal, push rod 10 promotes piston 4 to move forward, and return spring 8 becomes short by pressure, and pull bar 3 is ineffective, and at this moment pull bar 3 just acts on by pull bar spring 16, and the back-up ring 7 on pull bar 3 is sealed oil-in 5, and inner high voltage oil in chamber just flows out from oil outlet 11.
The top position place of cylinder body 1 section after corresponding piston 4 movement travel of two liquid chamber 2 is respectively equipped with oil-through hole 12, two oil-through holes 12 are connected by a pipeline 21, oil-through hole 12 is provided with steel ball 13, and steel ball 13 is pressed on the bolt 15 being installed on cylinder body 1 by steel ball and spring 14. When pedal promotes two chamber pistons 4 simultaneously, two chamber inner high voltage oil all back down steel ball 13 and make two chamber intercommunications, equal to reach two cavity pressure. When specifically implementing, in order to make steel ball 13 be backed down better, the front end of piston 4 is preferably provided with the scarp for backing down steel ball 13.
In order to make total pump of the present utility model to install more flexibly, as shown in Figure 3 and Figure 4, the uper side surface of cylinder body 1 and downside surface are respectively equipped with mounting plate 17, and mounting plate 17 is distributed with screw 18. During installation, it is possible to select corresponding mounting face as required, carry out locking through screw 18 by screw.
In order to ensure overall stopping property, push rod 10 is preferably provided with sealing leather collar 19 with the periphery of piston 4 junction. Further, the part periphery that push rod 10 passes liquid chamber 2 is preferably overlapped and is had dw 20.
So, owing to the utility model comprises two liquid chamber 2, when not changing global shape, cylinder holes increases one times, and discharge capacity is original 1.5 times, therefore brakes better effects if, is more suitable for the agricultural equipments such as large-scale tractor, reaper and uses.
