For receiving the signal of the temperature sensor, and the opening and closing of the first valve 5 is controlled, while controlling the second valve 6 in the first station
Switch between second station.
The specific work process of speed changer cooling system described in the present embodiment is as follows:
Since assistant cooling structure 4 is connected to water tank 3, under different operating conditions, oil liquid in speed changer 1 can be with
Coolant liquid in assistant cooling structure 4 carries out heat exchange, and the temperature of 1 inner fluid of speed changer is raised and lowered.
When the oil liquid in speed changer 1 is in low-temperature condition, the temperature of temperature sensor senses to 1 inner fluid of speed changer is low
In the temperature range of setting, at this point, temperature sensor sends a signal to transmission control unit 8, transmission control unit 8 is controlled
First valve 5 is opened, while being controlled the second valve 6 and being in the first station, so that coolant circuit is connected, it is cold in water tank 3
But liquid flows into cooling passage by the first valve 5, while the oil liquid in speed changer 1 flows into oil liquid cooling by the second valve 6
After the coolant liquid that temperature is high in channel, with cooling passage carries out heat exchange, then speed changer 1 is flowed back to, to make the temperature of oil liquid

Unit 8, transmission control unit 8 control the first valve 5 and close, while controlling the second valve 6 and being in second station, to make cold
But liquid circuit disconnects, while the oil liquid in speed changer 1 directly flows back to speed changer 1 by the second valve 6, i.e., only passes through supplement heat rejecter
Structure 4 reduces the oil liquid temperature in speed changer 1；
When the oil liquid in speed changer 1 is in the condition of high temperature, the radiating requirements of speed changer 1 are high, at this point, temperature sensor sense
The oil liquid temperature that should be arrived in speed changer 1 is higher than the temperature range of setting, and temperature sensor sends a signal to transmission control unit
8, transmission control unit 8 controls the first valve 5 and opens, while controlling the second valve 6 and being in the first station, to make coolant liquid
Circuit is again switched on, while the oil liquid in speed changer 1 flows into the oil passage of cooler 2 again by the second valve 6, with cooling
After the low coolant liquid of liquid intra passage temperature carries out heat exchange, then speed changer 1 is flowed back to, that is, passes through cooler 2 and assistant cooling structure 4
Collective effect reduce the oil liquid temperature in speed changer 1 quickly；
Therefore, speed changer cooling system provided in an embodiment of the present invention, by temperature sensor to the work temperature of speed changer 1
Degree is measured in real time, so that speed changer cooling system be enable to more precisely control the operating temperature of speed changer 1, makes speed change

Mouth connection, the oil outlet of by-passing valve 7 are connected to the speed changer oil return opening.
When the radiating requirements of speed changer 1 are high, the second valve 6 can be opened, at this point, the pressure of the oil circuit is low
In the setting pressure of by-passing valve 7, by-passing valve 7 is in the first station, i.e. the oil outlet of by-passing valve 7 and oiler disconnects, and therefore, becomes
Oil liquid in fast device 1 carries out heat exchange by the cooling-part that the second valve 6 flows into oil liquid cooling duct, with coolant liquid device 2
Afterwards, then speed changer 1 is flowed back to, in addition, since assistant cooling structure 4 is connected to water tank 3, the oil under different operating conditions, in speed changer 1
Liquid can carry out heat exchange with the coolant liquid in assistant cooling structure 4, therefore, when the radiating requirements of speed changer 1 are high, by cold
But the collective effect of device 2 and assistant cooling structure 4 reduces the oil liquid temperature in speed changer 1；
When the radiating requirements of speed changer 1 are low, the second valve 6 can be made to close, at this point, the oil liquid in speed changer 1 cannot lead to
It crosses the second valve 6 and flows into oil liquid cooling duct, when the pressure of speed changer 1 is lower than the setting pressure of by-passing valve 7, by-passing valve 7 is still
It is so in the first station, the oil outlet and oiler of by-passing valve 7 disconnect, when the pressure of speed changer 1 is greater than the setting pressure of by-passing valve 7
When power, by-passing valve 7 is in second station, at this point, the oil outlet of by-passing valve 7 is connected to oiler, the oil liquid in speed changer 1 passes through
Speed changer 1 is directly flowed back to after by-passing valve 7, i.e., only reduces the oil liquid temperature in speed changer 1 by assistant cooling structure 4；
Therefore, the embodiment of the present invention can flow to the oil liquid in speed changer 1 and be carried out by the opening and closing of the second valve 6 of control
Control, selectively turns on cooler 2, so that speed changer 1 is met the radiating requirements under different operating conditions, especially when speed changer 1
When radiating requirements are low, the oil liquid in speed changer 1 can directly flow back to speed changer 1 by by-passing valve 7, without passing through cooler 2, thus
