Control principle：
Oil circuit as shown in Figure 1 connects and control principle drawing, and its critical piece and oil circuit connection are as follows：
1. the inlet port of nutsch filter (2) is connected with oil sump (1), and the fluid of system interior circulation all flows through nutsch filter (2), with
The cleannes of raising system fluid, the oil-out of nutsch filter (2) is connected with oil pump (4) inlet port；
2. the pressure regulation oil-feed port (6P) of the oil-out of oil pump (4) and main oil-way pressure regulating valve (6) and oil pump check valve (3) phase
Even, and by pressure regulation all-pass oil throttle orifice (7) communicate, its pressure regulation draining with the left end (all-pass oil end) of main oil-way pressure regulating valve (6)
Mouth (6B) is communicated with the inlet port of oil pump (4)；Wherein main oil-way pressure regulating valve (6) is 3-position-3-way mechanical slide valve；
3. the pressure regulation oil-out (6A) of main oil-way pressure regulating valve (6) and the lubrication oil supply mouth (9P) lubricating guiding valve (9) and cooling
The oil-in of device (11) is connected, and is communicated with the left end (logical oil end) of lubrication guiding valve (9) by lubrication logical oil throttle orifice (10)；Its
Middle lubrication guiding valve (9) is 2/2-way mechanical slide valve；
4. the oil-out of cooler (11) is connected with filter press (13) and filter pressing check valve (12), when filter press (13) occurs
A certain degree of blocking or through-flow limited, when pressure reduction is more than a threshold value in front and back, filter pressing check valve (12) may turn on
Assist through-flow；
5. the outlet of filter press (13) outlet and filter pressing check valve (12), the lubrication oil-out (9A), cold of lubrication guiding valve (9)
But the cooling oil-feed port (15P) of control valve (15) is connected, and pass through lubrication only oily throttle orifice (8) acts on lubrication guiding valve (9) simultaneously
Right-hand member (only oily end), and go to the branch road of tooth axle lubrication portion (17) by lubricating throttle orifice (14)；
6. the cooling oil-out (15A) of cooling control valve (15) leads to the branch road of clutch cooling segment (16), and passes through
Pressure regulation is entirely stopped oily throttle orifice (5) and is communicated with the right-hand member (complete only oily end) of main oil-way pressure regulating valve (6).
Operation principle：
1) change speed gear box cooling and lubricating controls work matrices
2) operation principle
Just establish pressure：Oil pump (4) starts to rotate, and main oil-way pressure regulating valve (6) works in low order end (complete only oily end), Zhi Daozhu
Oil circuit pressure reaches system minimum oil pressure and (more can adjust spring initial compression force and main oil-way pressure regulating valve (6) according to demand
End face size determining), arrive the pressure at main oil-way pressure regulating valve (6) left end (all-pass oil end) through pressure regulation all-pass oil throttle orifice (7)
Effect is enough to overcome spring starting force, main oil-way pressure regulating valve (6) beginning action；
Low discharge cools down：It is (complete that main oil-way pressure regulating valve (6) works in high order end in the presence of two ends pressure reduction and spring force
Logical oil end), the inlet port that unnecessary fluid flows back to oil pump (4) through pressure regulation drain tap (6B) continues cycling through, and a part of flow has
Its pressure regulation oil-out (6A) flows to lubrication branch road；Low discharge cooling is usually used in low temperature or car load normally travel caloric value relatively
Little operating mode, now, the collective effect of the pressure reduction and spring that act on lubrication guiding valve (9) left and right two ends makes to lubricate guiding valve (9) work
The duty ratio of time making in left position (logical oil end) is big, and the overwhelming majority flows through lubrication guiding valve (9), and fraction fluid flows through cooler
(11) and filter press (13) branch road, then mainly act on tooth axle lubrication portion (17), cooling is adjusted according to actual condition and controls
The openings of sizes of valve (15), controls the flow going to clutch cooling segment (16).
Big flow cools down：Main oil-way pressure regulating valve (6) works in centre position in the presence of two ends pressure reduction and spring force,
I.e. half logical half stop is divided, and described half logical half stop divides the opening of corresponding described pressure regulation oil-out (6A) and described pressure regulation draining
The closed mode of mouth (6B).Fluid flows to lubrication branch road from its pressure regulation oil-out (6A)；Big flow cooling is usually used in high temperature
Or car load badly travels the larger operating mode of caloric value, now, the lubrication pressure reduction at guiding valve (9) left and right two ends and being total to of spring are acted on
Same-action make to lubricate guiding valve (9) work in right position (only oily end) duty ratio of time big, fraction flows through lubrication guiding valve (9),
Most of part fluid flows through cooler (11) to carry out heat exchange and passes through filter press (13) branch road, is adjusted cold according to actual condition
But the openings of sizes of control valve (15), clutch cooling segment (16) is gone in control and the flow of tooth axle lubrication portion (17) divides
Join.
The beneficial effect that the preferred embodiments of the present invention technical scheme is brought includes：
1) technical solution of the present invention provides a kind of clutch cooling and the actively independent control of tooth axle system of automatic gear-box
System processed, will high-low pressure and small-large flow system separately, the efficiency of pressure source can be effectively improved it is possible to be applied to AT
In DCT change speed gear box.
2) technical solution of the present invention, cooling and lubricating is independent, can effectively reduce power source design power, energy-conservation fall
Consumption.
3) the present invention program employs 2 mechanical valve, and 1 electromagnetic valve can effective control system pressure scope and flow
Distribution, and decrease the quantity of the utilization quantity especially electromagnetic valve of valve, greatly reduce cost.
4) this cooling and lubricating control system achieves main oil pressure and most economical effective control of cooling, hydraulic system of lubrication
System.
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments it should be understood that non-limiting embodiment party
Case illustrates as just example.The protection domain of the application essence to be required more is embodied in independent claims and provides
Scope, and its dependent claims.
