Beneficial effect: the vibratory roller switching valve that the utility model provides, has lag function, operates light, flexible, compact structure.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is structural representation of the present utility model.
In figure: valve body 1, contiguous block 2, valve gap 3, spring sheet 4, thrust bearing 5, pin 6, relief valve block 7, in line check valve 8, ball check valve 9, coupling shaft 10, end cap 11, rotor 12, limited post 13, spool 14, valve pocket 15, spacer 16, stator 17, filler opening A, return opening B, left steering oil outlet C, right steering oil outlet D.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described.
As depicted in figs. 1 and 2, a kind of vibratory roller switching valve, comprise valve body 1, contiguous block 2, valve gap 3, spring sheet 4, thrust bearing 5, pin 6, relief valve block 7, in line check valve 8, ball check valve 9, coupling shaft 10, end cap 11, rotor 12, limited post 13, spool 14, valve pocket 15, spacer 16, stator 17, filler opening A, return opening B, left steering oil outlet C, right steering oil outlet D, the spool 14 matched and valve pocket 15 is provided with in described valve body 1, the left end of spool 14 is located by spring sheet 4, coupling shaft 10 is connected with spool 14, movable valve plug 14 and valve pocket 15 can be with to misplace, the output shaft of rotor 12 is connected with valve pocket 15, follow the tracks of spool 14 for driving valve pocket 15 again to align, described valve body 1 offers filler opening A, return opening B, left steering oil outlet C, right steering oil outlet D.Described valve body 1 bottom is provided with the end cap 11 for back cover, and the other end of valve body 1 is provided with valve gap 3.Described filler opening A place is provided with in line check valve 8.Described filler opening A place is provided with ball check valve 9.Relief valve block 7 is also provided with above described valve body 1.The right-hand member of described coupling shaft 10 is also provided with limited post 13.Spacer 16 is also provided with, for spool 14 and limited post 13 being separated in described valve body 1.
Utility model works process is as follows: during road roller straight-line travelling, and valve pocket 15 and spool 14 align, and located by spring sheet 4, switching valve is in meta, and the fluid that steerig pump exports flows into from filler opening A, flows back to fuel tank through valve pocket 15 and spool 14.
Pressure road turn to, rotating of steering wheel several angle time, spool 14 overcomes the pressure of spring sheet 4 and valve pocket 15 misplaces, pressure oil enters valve pocket 15 from filler opening A, measure motor is entered through hydraulic fluid port and oil duct, then steering cylinder one group of chamber is entered from left steering oil outlet C or right steering oil outlet D, reverse promotion steering cylinder piston, forces forward and backward frame to deflect, and realizes pressure road and turns to.The rotor of measure motor can drive valve pocket 15 to follow the tracks of spool 14 and again align, and recovers return, realizes servo-actuated machine feedback.
The utility model vibratory roller switching valve has lag function, operates light, flexible, compact structure.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
