Description of drawings
The electronic oil cylinder hydraulic device of Fig. 1 commercial car cab tilting device scheme drawing.
The integrated scheme drawing of the electronic oil cylinder hydraulic device of Fig. 2.
The specific embodiment
As shown in Figure 1, bidirectional hydraulic pump 1 adopts centering type rotating cylinder formula plunger pump structure, and its input shaft is connected with motor 2, and two oil circuit mouths of bidirectional hydraulic pump 1 also connect or door fluid control valve 3, an and fluid control valve 4.
Or a door fluid control valve 3 is one-way control valves of a kind of both direction, be mouth in the middle of wherein, or the mouth of a fluid control valve 3 is connected to the rod chamber of oil cylinder 5; The rod chamber of oil cylinder 5 and or the oil duct of door between the fluid control valve 3 on be connected with two rod chamber dashs pot valve 6,7 and safety valve 8.
A mouth of bidirectional hydraulic pump 1 is connected to the rodless cavity of oil cylinder 5, is connected with hydraulic control one-way valve 9 on the oil duct of the rodless cavity of oil cylinder 5; Be connected with two check valves 10,11 that oppositely are provided with on the oil input channel of hydraulic control one-way valve side by side.
Or the door fluid control valve 3 and and door fluid control valve 4 between be connected with change-over valve 12 and dash pot valve 13.
Be connected UNICOM with the oil inlet of door fluid control valve 4 with oil sump 14.
The principle of work of this system is: when the left end of bidirectional hydraulic pump 1 is exported high pressure oil, close with the spool in door fluid control valve 4 left sides, the spool on right side is opened, and oil sump 14 is to bidirectional hydraulic pump 1 fuel feeding; Pressure oil enters the rodless cavity of oil cylinder 5 by check valve 10, hydraulic control one-way valve 9, the spool of while or door fluid control valve 3 is closed the right side oil duct to the right under the effect of pressure oil, pressure oil by or door fluid control valve 3 mouths and two dashs pot valve 6,7 enter the rod chamber of oil cylinder 5, because the rodless cavity of oil cylinder 5 and the pressure reduction between the rod chamber make the startup that oil cylinder 5 is mild, after oil cylinder 5 starts, hydraulic oil in the rod chamber of oil cylinder 5 under pressure, by or door fluid control valve 3 get back to the rodless cavity of oil cylinder 5.
