Fig. 2 is a kind of schematic diagram of hydraulic stepless transformation system of the utility model.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type is described in further detail.Only this state, the utility model occur in the text or will occur upper and lower, left and right, it is preceding, Afterwards, the orientation such as inside and outside word is not the specific restriction to the utility model only on the basis of the attached drawing of the utility model.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of hydraulic stepless transformation system, including laterally leads Bar 1, Der Laengslenker 2, regulating mechanism 3, the first transformation oil cylinder 4 and the second transformation oil cylinder 5;It is fixed on the transverse direction guide rod 1 First sliding sleeve 6, the Der Laengslenker 2 are inserted in the first sliding sleeve 6, and the both ends of the transverse direction guide rod 1 are equipped with third sliding sleeve 7, described Third sliding sleeve 7 is inserted in locating rod 8;The both ends of the Der Laengslenker 2 pass through respectively the second sliding sleeve 13 and the first transformation oil cylinder 4 and The connection of second transformation oil cylinder 5, second sliding sleeve 13 can be with respect to the piston rod of the first transformation oil cylinder 4 and the second transformation oil cylinder 5 Rotation;The regulating mechanism 3 is connect with lateral guide rod 1, and lateral guide rod 1 can be driven to move up and down;The first transformation oil cylinder 4 It is connect with the first oil inlet oil circuit 9 and the first fuel-displaced oil circuit 10, the second transformation oil cylinder 5 goes out with the second oil inlet oil circuit 11 and second Oil circuit 12 connects.The first fuel-displaced oil circuit 10 and the second fuel-displaced oil circuit 12 are connect with executive component 14.It is described to execute member Part 14 is another hydraulic cylinder.The regulating mechanism 3 is hydraulic cylinder, linear motor or the linear motion mechanical device being driven by motor Deng, the present embodiment by taking hydraulic cylinder as an example, it is connected with and adjusts oil circuit 15.
When work, hydraulic oil from the first oil inlet oil circuit 9 enter the first transformation oil cylinder 4 plunger shaft in, push piston rod to Left movement, so that Der Laengslenker 2 be pushed to rotate clockwise.Power is transmitted to the second transformation oil cylinder 5 by Der Laengslenker 2, drives The piston of second transformation oil cylinder 5 moves right, and the hydraulic oil in the plunger shaft of the second transformation oil cylinder 5 is extruded, and passes through second Fuel-displaced oil circuit 12 enters executive component 14 and generates lower pressure.Conversely, hydraulic oil enters the second transformation oil cylinder 5, Der Laengslenker 2 is pushed It rotates counterclockwise, hydraulic oil is discharged into executive component 14 from the first transformation oil cylinder 4, can also generate lower pressure.
Assuming that the first transformation oil cylinder 4 as the piston area of the second transformation oil cylinder 5, is S, the work of the second transformation oil cylinder 5 Plug chamber oil pressure is p1, and the plunger shaft oil pressure of the first transformation oil cylinder 4 is p2, and the second sliding sleeve 13 of the second transformation oil cylinder 5 is apart from transverse direction The tie point of guide rod 1 and Der Laengslenker 2 distance is l1, and the second sliding sleeve 13 of the first transformation oil cylinder 4 is apart from lateral guide rod 1 and longitudinal direction The tie point distance of guide rod 2 is l2, and Der Laengslenker 2 is a relative to horizontal position angle.When the first transformation oil cylinder 4, the second transformation When the lever system equalising torque that oil cylinder 5, lateral guide rod 1 and Der Laengslenker 2 form, there is p1*S*l1*sin (a)=p2*S*l2* Sin (a), i.e. p1*l1=p2*l2.
