Description
Technical field
The utility model belongs to the remote steering technologies field of automobile and other plant equipment, and in particular to a kind of hydraulic pressure behaviour
Vertical system.
Background technology
In existing heavy truck and special vehicle, when needing manual transmission to carry out remote control, generally
Remote control, or both ends leverage, the middle transmission for carrying out power by pushing-pulling flexible shaft over long distances are carried out using leverage.
In both control modes, former mechanism is complicated, is limited greatly by space, steering force is larger, and when vehicle jolts, gear change hand lever is not
Disconnected vibration, or even produce phenomenon of losing rank；Latter gear is relatively easy, overcomes the phenomenon that vibration is lost rank, but push-and-pull is soft
Axle also there are certain requirements to arrangement space, and pushing-pulling flexible shaft can constantly rub in manipulation process with overcoat, cause to manipulate resistance
Increase, meanwhile, the service life of pushing-pulling flexible shaft is shorter, and maintenance cost is high.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic control system, overcomes the deficiency of existing steerable system so that
Mechanism is simple, and manipulation is light, and maintenance cost is low, and service life extends.
The technical solution of the utility model is：Two two-way cylinders are connected in parallel by pipeline, manipulated wherein
The piston rod of one oil cylinder, when it is pulled out or is promoted, the caused fluid pressure of the oil cylinder will be applied to another oil
On piston in cylinder, the piston rod of this oil cylinder is driven to carry out the motion opposite with a upper oil cylinder.Meanwhile by adjusting two
The internal diameter of oil cylinder and the diameter of piston rod can carry out input and be controlled with power output and the ratio of displacement.
The beneficial effects of the utility model are that the utility model uses the remote control of double oil cylinders so that the arrangement of oil cylinder
Position can arbitrarily arrange that the arrangement of pipeline also very flexibly, is almost not limited by a space, as long as in addition, system as needed
Parameter designing is reasonable, the steering force loss meeting very little of system, can effectively provide the manipulation portability of system, meanwhile, oil cylinder exists
Abrasion in manipulation process is slight, and the service life of system can significantly improve, and maintenance cost is very low.

Embodiment
Referring to Fig. 1, hydraulic control system of the present utility model is mainly changed manually by oil cylinder (1), oil cylinder (2), two-position three way
To valve (3), lubricating cup (4) composition.
Its operation principle is as follows：
Referring to Fig. 1, Fig. 3, oil cylinder (1) and oil cylinder (2) are internal diameter of cylinder D and diameter of piston rod d difference identical two
Individual single-piston rod two-way cylinder.When two-position three-way hand change valve (3) is in A positions, oil cylinder (1) is manipulated, makes oil cylinder (1)
When piston rod moves to right L length, the part fluid in a2 chambers is pressed onto by the piston of oil cylinder (1) in the b2 chambers of oil cylinder (2), high-voltage oil liquid
The piston of oil cylinder (2) is promoted to be moved to the left L length, meanwhile, the part fluid in the b1 chambers of oil cylinder (2) is by the piston of oil cylinder (2)
It is pressed onto in the a1 chambers of oil cylinder (1), so, the piston rod of oil cylinder (2) will realize under the drive of piston to be moved to the left, and
Oil cylinder (2) power output and the power inputted to oil cylinder (1) are equal in magnitude, and then can control work by the piston rod of oil cylinder (2)
Device carries out the action of respective direction；If manipulate oil cylinder (1), when the piston rod of oil cylinder (1) is moved to left L length, the portion in a1 chambers
Point fluid is pressed onto by the piston of oil cylinder (1) in the b1 chambers of oil cylinder (2), and high-voltage oil liquid promotes the piston of oil cylinder (2) to move right L length
Degree, meanwhile, the part fluid in b2 chambers is pressed onto by the piston of oil cylinder (2) in the a2 chambers of oil cylinder (1), so, the piston of oil cylinder (2)
Bar will be realized under the drive of piston and moved right, and oil cylinder (2) power output and the power size to oil cylinder (1) input
It is equal, and then the action of equipment progress respective direction can be controlled by the piston rod of oil cylinder (2).So it is achieved that logical
Crossing manipulation oil cylinder (1) makes oil cylinder (2) according to 1: 1 ratio power output and displacement.
Referring to Fig. 1, Fig. 3, to realize that non-1: 1 ratio controls, then internal diameter of cylinder D and diameter of piston rod d must be entered
Row adjustment so that fluid is thus realized to the active area of piston respectively into identical ratio in a2 and b2 chambers, a2 and b2 chambers
By manipulating oil cylinder (1) make oil cylinder (2) according to non-1: 1 ratio power output and displacement.I.e., it is possible to realize living to oil cylinder (1)
When stopper rod inputs a power and displacement, oil cylinder (2) can export scaling or the power reduced and a displacement.
Referring to Fig. 1, when two-position three-way hand change valve (3) is in B positions, four chamber a1 of oil cylinder (1) and oil cylinder (2),
A2, b1, b2 are connected by two-position three-way hand change valve (3) with lubricating cup (4), so in initial assembling, can carry out fluid
Filling, and pass through left and right manipulate oil cylinder (1) or oil cylinder (2) carry out cylinder piston rod relative position adjustment.Grown in system
After time use, if because fluid leakage cause the piston rod relative position of oil cylinder (1) and oil cylinder (2) incorrect when, can also be
When two-position three-way hand change valve (3) is in B positions, the adjustment of oil cylinder (1) and oil cylinder (2) piston rod position is carried out.
Referring to Fig. 2, Fig. 4, oil cylinder (5) and oil cylinder (6) be internal diameter of cylinder D it is identical with diameter of piston rod d difference or
Two different double piston-rod two-way cylinders, its operation principle is essentially identical with Fig. 1, just repeats no more here.Unlike,
The system conveniently by the internal diameter of cylinder D and diameter of piston rod d of two oil cylinders of adjustment in addition to it can carry out ratio control, relatively
In single-piston rod two-way cylinder hydraulic control system in parallel, left and right is carried out in the power that identical size is inputted to oil cylinder (5)
During manipulation, operating pressure caused by hydraulic system is identical.
