Power, temperature-sensing valve 300 are closed (Fig. 8), into the second hydraulic fluid port P gear oil all after in valve from temperature-sensing valve first
Hydraulic fluid port O flows out, final oil return to speed changer 200.The process cooler 400 is not involved in work；
When operating mode changes, t0 increases, t1≤t0 ＜ t2,300 Spool assembly 1 of temperature-sensing valve overcomes bullet under temperature action
The elastic force of spring 2 is moved to the left so that the first hydraulic fluid port O and the 4th hydraulic fluid port B are connected, and temperature-sensing valve is in half-open position (Fig. 9), enter
A gear oil part of second hydraulic fluid port P is flowed out from third hydraulic fluid port A enters the 4th hydraulic fluid port B, then finally with not having after subcooler 400
There is remaining fluid through subcooler 400 together from hydraulic fluid port (being always O before) outflow, oil return to speed changer 200.The process portion
Dividing fluid, cooling system plays certain cooling effect, oil temperature t0 is adjusted through subcooler 400.
If cooling capacity is not enough to that speed changer is allowed to reach equilibrium temperature when temperature-sensing valve 300 is half-open, t0 can continue to increase, when
During t0 >=t2,300 standard-sized sheet of temperature-sensing valve (Figure 10), the gear oil into the second hydraulic fluid port P is all flowed out from third hydraulic fluid port A through supercooling
Enter the 4th hydraulic fluid port B after device, then through the first hydraulic fluid port O oil returns to speed changer 200.The process cooling system cooling power reaches most
Greatly, oil temperature t0 is adjusted with maximum capacity.
More than, the only preferred embodiment of the utility model is not limited only to the scope of the utility model, Fan Yiben
The equivalence changes and modification that the content of utility model range is done all should be the technology scope of the utility model.
