Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The embodiments of the present invention are described in detail below in conjunction with attached drawing.
The structure of the present embodiment includes gearbox 4, engine 5, oil cooler 14, oil inlet pipe, flowline, inlet tube 12, goes out
Liquid pipe 13, liquid back pipe 8, liquid flowing tube 10 and water tank 9, the oil cooler 14 are connect by oil inlet pipe and flowline with gearbox 4, are led to
It crosses inlet tube 12 and connects water tank 9, engine 5 is connected by outlet tube 13, is connected by liquid back pipe 8 between engine 5 and water tank 9
It connects, the engine 5 is equipped with thermostat 1 and water pump 11, and the inlet tube 12 is connected with thermostat 1 by liquid flowing tube 10
It connects.
In the present embodiment, the inlet of 12 one end of inlet tube connection oil cooler 14, other end connection water tank 9 go out liquid
Mouthful, 13 one end of outlet tube connects the liquid outlet of oil cooler 14, and the other end connects engine water pump 11,8 one end of liquid back pipe connection hair
The liquid outlet of the thermostat 1 of motivation 5, the other end connect 9 inlet of water tank, and 10 one end of the liquid flowing tube connects on engine 5
The inlet of thermostat 1, the other end connect inlet tube 12 by three-way connection.
In the present embodiment, the automatic transmission fluid cooling system further includes siphon pipe 6,6 one end of the siphon pipe
Engine water pump 11 is connected, the other end connects liquid flowing tube 10.
In the present embodiment, the automatic transmission fluid cooling system further includes thermostat 2 16, the oil inlet pipe packet
Oil inlet pipe 1 and oil inlet pipe 22 are included, one 1 both ends of oil inlet pipe are separately connected 14 oil outlet of 4 oil inlet of gearbox and oil cooler, into
22 one end of oil pipe connects oil inlet pipe 1 by three-way connection, and the other end connects the oil return opening of thermostat 2 16, and flowline includes
Flowline 1 and flowline 2 15, one 3 both ends of the flowline are separately connected 2 16 oil inlet of 4 oil outlet of gearbox and thermostat
Mouthful, 2 15 both ends of flowline are separately connected 14 oil inlet of 2 16 oil outlet of thermostat and oil cooler.
The operation principle of this cooling system is as follows：
1, after engine 5 starts, if the thermostat 1 on engine 5 is not opened, engine water pump 11 provides cooling hydraulic pressure
Power, coolant liquid pass through inlet tube 12, oil cooler 14, liquid flowing tube 10, outlet tube 13, in 5 inside cylinder sleeve cycle of engine；
2, when TOT Transmission Oil Temperature is not up to 40 DEG C, while coolant temperature is also not up to 40 DEG C, and thermostat 4 is closed, and is become
Fast case oil is recycled by flowline 1, oil inlet pipe 22 and oil inlet pipe 1, does not pass through oil cooler 14；
3, when TOT Transmission Oil Temperature reaches 40 DEG C, while coolant temperature also gradually rises, and thermostat 2 16 is opened, speed change
Case oil enters oil cooler 14 by flowline 1, thermostat 2 16 and flowline 2 15, then returns to speed change by oil inlet pipe 1
Case 4, this process oil cooler 14 are equivalent to heating hydraulic oil；
4, when coolant temperature reaches 80 DEG C or so, the thermostat 1 of engine 5 is opened, and inlet tube 12, oil cooling are passed through
Device 14, outlet tube 13, liquid flowing tube 10, liquid back pipe 8, cylinder sleeve of engine carry out systemic circulation.
In above process, the effect of liquid flowing tube 10 is, the thermostat 1 in engine 5 is prevented to be in the feelings closed
Under condition, coolant liquid only recycles inside engine 5 without oil cooler 14.It is in closing in the thermostat 1 of engine 5
In the case of, the inlet and liquid outlet of oil cooler 14 do not have pressure difference, are in off state, and coolant liquid does not enter oil cooler 14 and follows
Ring cannot cool down gear box oil, to which 4 temperature of gearbox can be caused to increase.
After liquid flowing tube 10 is arranged, no matter the thermostat 1 of engine 5 is unlatching or closed state, 14 feed liquor of oil cooler
Mouthful and liquid outlet have pressure difference, be in access, therefore have always coolant liquid enter oil cooler 14 to gear box oil carry out it is cold
But.
In above process, the effect of siphon pipe 6 is that siphonage occur to prevent liquid flowing tube 10, causes coolant liquid not by returning
Liquid pipe 8 keeps 5 temperature of engine excessively high to make water tank 9 not work.No matter engine 5 always has in large and small cycles
Coolant liquid participates in the heat exchange of oil cooler 14, ensures that gear box oil works under reasonable working temperature.
Above-mentioned cooling system can be used in fire fighting truck, coalmine rescue drilling machine, coal bed gas drilling machine, oil-well rig, oil and repair
In the special type chassis such as well machine, the requirement on chassis can be met.
The preferred embodiment that these are only the utility model, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
