Embodiment
As shown in Figure 1, Figure 2 and Figure 3, Automobile electronic-control hydraulic independent shaft end drives with end cap integrated change valve axle head motor, comprise end cap body 1 and piston 5, be characterized in: circumferentially setting-in valve core shell 2 on end cap body 1, be positioned at that the cylinder barrel 4 of valve core shell 2 is outer overlaps cartridge spool 3, spring 10, spool 3 from top to bottom; Wherein also can move up and down in the gap of spool 3 between valve core shell 2 and cylinder barrel 4;
Described piston 5 is positioned at cylinder barrel 4; Described spool 3 cylindrically, it offers upper oil hole 11 and lower oilhole 12; Described valve core shell 2, cylinder barrel 4 and end cap body 1 top and bottom offer corresponding high pressure oilhole 8 and low pressure oilhole 9, offer the spool driving pressure oilhole 7 leading to valve core shell 2 and cylinder barrel 4 gap in the side of end cap body 1 respectively near the position of upper end portion and side near the position of underpart.
The high pressure oilhole 8 that described cylinder barrel 4 upper and lower part is offered is circumferentially, and quantity is respectively 4; The upper oil hole 11 that described spool 3 is offered and lower oilhole 12 circumferentially, and quantity be respectively one week 3; The high pressure oilhole 8 that described valve core shell 2 is offered and low pressure oilhole 9 quantity are respectively 2, and position is relative.
Described end cap body 1 is provided with the low pressure corresponding with low pressure oilhole 9 and is communicated with oil pocket 13 and the high pressure corresponding with high pressure oilhole 8 is communicated with oil pocket 14 near inner side.
Working procedure and principle:
When the present invention works, when being positioned at spool driving pressure oilhole 7 oil-feed of end cap body upper end, spool 3 is driven, spring 10 pressurized, spool 3 is to descending, upper oil hole 11 on it is aimed at the high pressure oilhole 8 on cylinder barrel 4 and valve core shell 2, and the high pressure hydraulic fluid port of high pressure oil outside end cap is injected in the rodless cavity of the cylinder barrel on piston 5 top, descent of piston; When descent of piston is to limit position, be positioned at spool driving pressure oilhole 7 oil-feed of end cap body lower end, be positioned at spool driving pressure oilhole 7 oil return of end cap body upper end simultaneously, the spool 3 being positioned at bottom is up, spring 10 pressurized, the high pressure oilhole 8 of lower oilhole 12 aligned with lower on bottom spool 3, the high pressure oilhole of high pressure oil outside end cap is injected in the cylinder barrel rod chamber of piston 5 bottom, piston stroking upward.Now the lower oilhole 12 of top spool 3 aims at the low pressure oilhole 9 on top; So alternately back and forth, pumping of piston, is moved by connecting rod band movable slider, rotor is circled in waved flute.
