Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.
The structure of steering wheel main control valve group of the present utility model, as shown in Fig. 4 a, Fig. 4 b, Fig. 4 c, comprising:Main valve body 1, solenoid directional control valve 2, the second safety valve 3, the 3rd inserted valve 4, check valve assembly 5, ball valve6, connector 7, the second inserted valve 8, the first inserted valve 9, the first safety valve 10.
Main valve body 1 is for each hydraulic valve piece is installed, and there are the equipped duct of valve member and hydraulic oil opening in its insideRoad.
The second safety valve 3, the first safety valve 10 are in parallel with A1 mouth loop and the B1 mouth loop of valve group respectively,Be used for carrying out overpressure protection.
Connector 7 is installed on main valve body 1 by screw, and the interface A1, the B1 that are connected with oil pump are provided.
Totally two of ball valves 6, provide the interface C1, the D1 that are connected with loof mechanism, wherein the A1 mouth of valve groupLogical with C1 oral groove, B1 mouth and D1 oral groove are logical.
Solenoid directional control valve 2 is two four-way patterns, is installed on main valve body 1 upper end, its oil-feed by screwMouth is connected with the outlet of check valve assembly 5, and oil return opening is connected with the drain tap G1 of valve group, and oil-out is logicalCross the duct, inside of main valve body 1 and the cover plate of the 3rd inserted valve 4, the first inserted valve 9 and the second inserted valve 8Be connected, solenoid directional control valve 2 is provided with operating grip, can be used for manual control.
The first inserted valve 9, the 3rd inserted valve 4 are hydraulic control one-way valve type inserted valve, and the second inserted valve 8 is baseThis check valve type inserted valve, in the equipped hole of its plugin card installation on main valve body 1, controls cover plate and passes through spiral shellNail is fixed on the surface of main valve body 1. The 3rd inserted valve 4 is arranged in the A1-C1 loop of valve group, and secondInserted valve 8, the first inserted valve 9 are arranged in the B1-D1 loop of valve group, and the second inserted valve 8 is gone back and valveThe A1 side loop of group connects.
Check valve assembly 5 is connected with A1, B1 side loop and the solenoid directional control valve 2 of valve group respectively.
In addition, the leakage hole G1 in valve group adopts the pipe joint of GB.
The hydraulic principle of steering wheel main control valve group as shown in Figure 5, in figure, A1 mouth, B1 mouth respectively withTwo oil-outs of main oil pump are connected, and C1 mouth is connected with 1# cylinder, and D1 mouth is connected with 2# cylinder, G1 mouth and oilCase is connected.
The electromagnet of solenoid directional control valve 2 must not when electricity, and its spool is in the function position shown in Fig. 5, theHydraulic control one-way valve in the cover plate of three inserted valves 4 and the first inserted valve 9 is all in illustrated function position,The 3rd inserted valve 4 and first inserted valve 9 these two inserted valves are in closed condition, and oil cylinder is logical to oil pumpRoad is cut off, and in-oil cylinder fluid cannot be discharged, thereby realizes lock rudder function. In addition, due to secondThe oil circuit control of inserted valve 8 is linked up with drain tap G1 through solenoid directional control valve 2, make the second inserted valve 8 inOpen mode, A1 mouth is just directly linked up with B1 mouth like this, and can realize not being with of motor and carry startup, fromAnd slow down hydraulic shock and the impact to electrical network.
After unit starting, when the electromagnet of solenoid directional control valve 2 obtains when electric, spool switches to left functionPosition work, now the pressure oil of major loop is divided into three tunnels after by check valve assembly 5, solenoid directional control valve 2,One tunnel is closed the second inserted valve 8, thereby cuts off the direct path between A1 mouth and B1 mouth; All the other two-wayPromote respectively the fluid-control one-way valve events in the cover plate of the 3rd inserted valve 4 and the first inserted valve 9, make the 3rdInserted valve 4 and the first inserted valve 9, in open mode, are realized A1 mouth and C1 oral groove logical, B1 mouth and D1Oral groove is logical. Now suppose the main oil pump outlet oil extraction being connected with A1 mouth, hydraulic oil is behind loop, left sideEnter 1# cylinder by C1 mouth and make rudder to counterclockwise rotating, the fluid that 2# cylinder is discharged is by D1 mouthGet back to the inlet port of main oil pump through B1 mouth. Vice versa.
In the time that system pressure exceedes the setting value of safety valve, the second safety valve 3 or the first safety valve 10 are automaticOpen, realize overpressure protection.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility modelBe not limited to above-described embodiment, in the ken possessing those of ordinary skill in the art, also canTo make various variations under the prerequisite not departing from the utility model aim.
