Accompanying drawing 2 is this utility modelTractorThe left view structural representation of power output clutch electrichydraulic control operating mechanism.
Detailed description of the invention
The utility model will be further described by the examples below.As shown in Figure 1 and 2:TractorPower output clutch electrichydraulic control operating mechanism, including: power output clutch switch 1, electrichydraulic control combination valve block 2, power output clutch oil cylinder 3, power output clutch separating mechanism 4, return spring 5, position-limit mechanism 6, oil inlet pipe 8, oil return pipe 9, flowline A10 and flowline B11；Power output clutch switch 1 is arranged on bridge instrumentation dish；Electrichydraulic control combination valve block 2 is bolted on roll-over protective structure 7, power output clutch oil cylinder 3 is connected on electrichydraulic control combination valve block 2 by flowline A10, electrichydraulic control combination valve block 2 side is provided with oil inlet pipe 8, and opposite side is provided with oil return pipe 9, and rear side is provided with flowline B11；Power output clutch separating mechanism 4 is connected with power output clutch oil cylinder 3, and position-limit mechanism 6 is arranged on transmission case 12.
Oil inlet pipe 8 on electrichydraulic control combination valve block 2, oil return pipe 9, flowline A10 and flowline B11, aforementioned four oil pipe respectively with the gear pump on tractor, transmission case 12, power output clutch oil cylinder 3, lifter on tractor connects；The fixing end of power output clutch oil cylinder 3 is fixed on roll-over protective structure 7 by oil cylinder axle 13；Piston rod 3.1 is connected with power output clutch separating mechanism 4 by bearing pin；Return spring 5 one end is connected with power output clutch separating mechanism 4, and one end is fixed on the hook plate 14 of clutch housing.The position-limit mechanism 6 being fixed on transmission case 12 is provided with adjustment bolt 6.1, adjusting nut 6.2.
When power output clutch switch is in opening, in electrichydraulic control combination valve block 2, electromagnetic valve obtains electric, path between oil inlet pipe 8 and the flowline A10 of electrichydraulic control combination valve block 2 is opened, pressure oil enters power output clutch oil cylinder 3, and piston moves in propulsion power output clutch oil cylinder 3, promote the power output clutch separating mechanism 4 being connected with piston rod 3.1, it is achieved the separation of double-action clutch medium power output clutch.The maximum displacement of oil cylinder is limited by the adjustment bolt 6.1 on adjustment position-limit mechanism 6, adjusting nut 6.2.When piston displacement reaches the angle that power output clutch separating mechanism 4 rotates, it is achieved the separation of power output clutch.
