Abstract
It the utility model is related to a kind of novel pressure regulating valve, including filter (1), hydraulic pump (2), check valve (3), the controller (7) being successively set on fluid pipeline, then fluid pipeline connection loading cylinders (9), for providing power；The controller (7) gathers the pressure value of pressure sensor one (6) and close loading cylinders (9) place's pressure sensor two (8) on fluid pipeline and carries out closed-loop control according to both differences, oil liquid pressure is kept to stablize, pass through the closed-loop control of controller, it ensure that output is equal with input pressure, improve shift quality, the overflow valve and accumulator set at the same time, in time can supplement oil liquid pressure, ensure the stabilization of input oil liquid pressure.
Description
Technical field
Automotive transmission field is the utility model is related to, is specifically a kind of novel pressure regulating valve.
Background technology
Hydraulic power mechanism in speed changer has its performance conclusive influence, and general work principle is to pass through fluid
To transmit pressure, and by adjusting fluid input to adjust pressure size, and then pressure is provided for gear shift operation, but fluid is in pipe
When road flows, its output pressure and input pressure inevitably produce deviation, and meeting extreme influence shift quality, can make when serious
It is sluggish into gearshift, it is prone to accidents.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel pressure regulating valve, to solve in the prior art
There are the defects of.
The technical solution that the utility model solves above-mentioned technical problem is as follows：
A kind of novel pressure regulating valve, including the filter (1), hydraulic pump (2), unidirectional being successively set on fluid pipeline
Valve (3), controller (7), then fluid pipeline connection loading cylinders (9), for providing power；Controller (7) the collection oil
Pressure sensor one (6) and close to the pressure value of loading cylinders (9) place's pressure sensor two (8) and poor according to both on liquid pipe road
Value carries out closed-loop control, keeps oil liquid pressure to stablize；
Further, the hydraulic pump (2) is driven by servomotor；
Further, when controller (7) detection pressure sensor one (6) pressure is more than setting value, controller (7), which is opened, to overflow
Valve (4) is flowed, reduces fluid input；During less than setting value, controller (7) opens accumulator (5), supplements fluid, increases pipeline pressure
Power；
The beneficial effects of the utility model are：By the closed-loop control of controller, output and the phase of input pressure ensure that
Deng, shift quality, while the overflow valve and accumulator set are improved, oil liquid pressure can be supplemented in time, guarantee input oil
The stabilization of hydraulic coupling.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In attached drawing, parts list represented by the reference numerals is as follows：
1st, filter, 2, hydraulic pump, 3, check valve, 4, overflow valve, 5, accumulator, 6, pressure sensor one, 7, controller,
8th, pressure sensor two, 9, loading cylinders.
Embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of novel pressure regulating valve, including filter (1), the hydraulic pressure being successively set on fluid pipeline
(2), check valve (3), controller (7) are pumped, then fluid pipeline connection loading cylinders (9), for providing power；The controller
(7) gather fluid pipeline on pressure sensor one (6) and close to loading cylinders (9) place's pressure sensor two (8) pressure value simultaneously
Closed-loop control is carried out according to both differences, keeps oil liquid pressure to stablize；
Further, the hydraulic pump (2) is driven by servomotor；
Further, when controller (7) detection pressure sensor one (6) pressure is more than setting value, controller (7), which is opened, to overflow
Valve (4) is flowed, reduces fluid input；During less than setting value, controller (7) opens accumulator (5), supplements fluid, increases pipeline pressure
Power；
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modification, equivalent replacement, improvement and so on, should be included in the guarantor of the utility model
Within the scope of shield.
