Detailed description of the invention:
The technical solution of the utility model is as shown in Figure 1, the left end connecting first 1 is screwed hole, this connects first right-hand member and is provided with the screwed hole matched with union joint 28 screw thread, it is provided with and the stepped hole of valve body 5 close-fitting in the left side of this screwed hole, this valve body right-hand member is provided with centre bore, the left side of central hole is provided with stepped hole hereinto, the small diameter cylinder cunning that cross section is the spool 1 of convex shape cylinder fits in described centre bore, the left end of the spool one of described convex shape cylinder is provided with stepped hole, the left end opening of this stepped hole and right-hand member is closed, gap is had between barrel and the step hole wall of described valve body left end of the step cylinder of this spool one, this step cylindrical wall is provided with radial hole, valve body 5 left end hole wall is provided with the screw thread matched with plug 2, the center of this plug be provided with the axial hole screwed hole first with described connection relative and connection, gap is had between left side and the right side of plug of spool one, spring 1 is located between the end face of described plug and spool one stepped hole。The spool 26 that cross sectional shape is convex shape cylinder is placed in the stepped hole connecting first right-hand member between described valve body and union joint two, gap is had between step barrel and the step hole wall being connected first right-hand member of this spool two right-hand member, the step barrel of this spool two sets radial hole, the left side annular end face of this spool two step cylinder contacts with the right side of described valve body, and between the left side of the right-hand member of spool two and union joint two, have gap, a left side for this spool two, the equal opening in right two ends, the left end of union joint 28 is provided with screw thread and is connected the corresponding threaded holes of first right-hand member, gap is had between described spool two right side and the left side of union joint two, spring 27 is located between annular end face and the left side of union joint two of spool two stepped hole。Surrounding distribution outside valve body centre bore has inside and outside axial hole, and outer axial hole is relative with the left side of the stepped hole of spool two, and interior axial hole is relative with the end face of spool one stepped hole。
The operation principle of the two-way fluid controller of this utility model hydraulic steering gear is, when the oil pressure of controller joint Single port higher than the pressure difference of joint Two-port netwerk oil pressure more than the setting value of spring two time, spool one end surface of step hole and the laminating of valve body left end end surface of step hole, spool two is made to overcome the elastic force of spring two to move right, spool two end surface of step hole separates with the you face of valve body right-hand member and produces gap, fluid is through the outer axial hole of surrounding valve body, gap between spool two and valve body end face, radial hole on spool two step hole wall enters in the hole of spool two, the axial hole of drive connector two is flowed out, (referring to Fig. 2)；
When the oil pressure of joint Two-port netwerk higher than the pressure difference of the oil pressure of joint Single port more than the setting value of spring one time, spool biend and the laminating of valve body right side, spool one overcomes the elastic force of spring one to be moved to the left under oil pressure effect, spool one end surface of step hole separates formation runner with the end surface of step hole of valve body left end, fluid from joint two axial hole, through spool two, valve body interior axial hole and spool one and valve body between gap and radial hole on spool one step hole wall enter in spool one through plug centre bore from joint one hole outflow (referring to Fig. 3)。
The operation principle of the two-way fluid controller of this utility model, two two-way fluid controlling organizations 10 are connected on the oil circuit 11 of hydraulic steering gear hydraulic cylinder 12 piston 13 both sides respectively, one end of the two-way fluid controlling organization of said two is connected with the oil circuit of hydraulic cylinder piston both sides respectively, and the other end is connected (referring to Fig. 4) respectively with steering control valve。Automobile is on road surface in driving process, in order to avoid the dither produced on steering wheel because there being small wave action to pass to wheel due to road surface, by two springs in fluid double-direction control mechanism being closed the setting of the elastic force of asphalt channel (gap), the oil pressure value of above-mentioned minor fluctuations is less than the power of spring, two-way fluid controller is closed mode, thus, steering wheel will not produce high frequency microvibration, when only there is bigger uneven road surface in road surface, when acting on the power of wheel more than the elastic force of spring, driver just can feel。
