Description
Technical field
The utility model belongs to automobile dynamic system technology cooling field, and in particular to a kind of transmission oil cooler temperature adjustment is returned
Road.
Background technology
Current major part AT vehicles or wet type DCT vehicle transmission oil coolers are all built-in, that is, are integrated in cooling system
In radiator, due to the fixed structure form of radiator, the structure of transmission oil cooler also receives larger limitation, can only make
Strip structure is made, and volume also receives corresponding limitation, if the heat dissipation capacity of speed changer is larger, the volume of built-in oil cooler
Increase will be very difficult, take into account volume, the moulding of even whole front face of radiator.
In addition, referring to Fig. 1, because built-in oil cooler is integrated in radiator, the connecting line of transmission oil is increased,
The flow of transmission oil is longer, needs longer pipeline to connect between oil cooler and speed changer, i.e., one oil inlet pipe, one go out
Oil pipe.
Referring to Fig. 1, a kind of arrangement of built-in oil cooler is higher than certain setting value such as 90 in the water temperature of engine 1
DEG C when, the first thermosistor 41 is opened, recirculated water engine water pump 6 effect under, from water jacket of engine cylinder cover interior circulation water warp
First thermosistor, is cooled down into radiator, and the recirculated water after cooling flows back to engine 1 again.Oil cooler 3 is integrated in radiator
In the hydroecium of 7 water outlet sides, so the water passage circulation system residing for built-in oil cooler 3 is systemic circulation.In oil cooler 3 in systemic circulation
Before opening, the inner fluid of speed changer 2 is heated without recirculated water.Thus, in speed changer 2 oil temperature rise it is very slow,
Especially become apparent from low ambient temperatures.Under low temperature, big, the oily flow of oil resistance is small in speed changer 2, causes the intermediate bearing of speed changer 2 to moisten
Cunning is bad, there is the risk of ablation.
The content of the invention
The purpose of this utility model is to solve under low temperature, because big, the oily flow of transmission oil resistance is small；Cause in speed changer
Between bearing insufficient lubrication, the problem of have ablation risk.
In order to solve the above problems, the utility model proposes a kind of transmission oil cooler temperature adjustment loop, including engine, change
Fast device and oil cooler, the oil cooler is installed on speed changer, in addition to is connected to water jacket of engine cylinder cover and engine water
Oil cooler temperature control section between pump, the oil cooler temperature control section includes being serially connected with the temperature control pipeline section of oil cooler.
Further, the oil cooler temperature control section also includes being serially connected in the heater cores before oil cooler.
Further, in addition to heater cores, the second thermosistor, the heater cores and oil cooler are connected in parallel on temperature control pipeline section
In, second thermosistor is connected to the two and is connected at water, and temperature control pipeline section or distribution oil are opened and closed by the second thermosistor
The flow of cooler and heater cores.
The beneficial effects of the utility model are：Directly using the recirculated water come out from cylinder head water jacket in oil cooler
Oil temperature preheated, improve the mobility of fluid, so solve at low temperatures, because oil temperature is not in oil cooler
Foot, causing oil to hinder, big, flow is small, and caused bearing lubrication is bad, the problem of ablation occur.In addition, oil cooler is directly installed on
On speed changer, fluid conveyance conduit connecting the two is saved, also by reduction fluid transmitting path, oily resistance is reduced.Adopting
With under the utility model arrangement, because the reduction of oil resistance declines, the oil consumption of engine is reduced to a certain extent.
Oil cooler is connected on after heater cores so that the recirculated water with higher temperature can be carried out by heater cores
Radiating, to realize in the purpose by circulating water oil cooler inner fluid.
