Description
Technical field
This utility model is related to automotive transmission Oil Cooling Technology field, specially a kind of transmission oil temperature control system.
Background technology
With the development of auto industry, more and more higher is required to the discharge of electromotor, oil consumption etc..Automatic transmission as send out
One of important accessory of motivation, the design of its performance and arrangement not only affect comfortableness, also directly affect the power consumption of electromotor.Mesh
Front automobile engine automatic transmission all carries out drive disk assembly cooling using lubricating oil substantially, in high rotating speed, high load capacity, high temperature
Under the conditions of oil temperature raise, because lubricating oil viscosity too low, so as to affecting the life-span of automatic transmission and producing abnormal sound.As shown in figure 1,
At present for solving automatic transmission lubricating oil high temperature problem under extreme conditions, generally arrange in the radiator 4 of electromotor
One oil cooler 7, when vehicle is travelled, the oil pump 3 being arranged in variator 2 delivers lubricating oil to carry out hot friendship in oil cooler 7
Change, return in automatic transmission after lubrication oil cooling, so as to reduce lubricating oil temperature.But, in engine cold-start, become
The lubricating oil of fast device can be also flowed in oil cooler, and now because temperature is too low, lubricating oil viscosity is big, cause friction loss big, therefore
Electromotor power consumption is caused to increase, so that oil consumption, discharge increase.And in this configuration, because oil cooler is arranged in radiator
Interior, cause radiator volume larger, be not easy to arrangement in enging cabin.
Content of the invention
The purpose of this utility model is to provide a kind of transmission oil temperature control system, and according to circumstances variator can be moistened
Lubricating oil is heated or cooled, so as to ensure that lubricating oil is in suitable temperature.
Transmission oil temperature control system described in the utility model, including：Radiator, the entrance of the radiator with start
The outlet connection of machine, the outlet of radiator are connected with the water inlet of electromotor；Valve body, the valve body are arranged on radiator inlet
Place, blocks for control or channeling fluid enters radiator；Oil pump, the oil pump is by the lubrication oil circulation of variator to heat exchange
In device；Heat exchanger, has the first and second two fluid passages, the stream in two fluid passages in the heat exchanger
Body medium carries out heat exchange in heat exchanger, and the wherein entrance and exit of first fluid passage is connected to form with the oil pump and is followed
Loop back path, the entrance of second fluid passage are connected with the outlet of electromotor, and the outlet of second fluid passage is entered with electromotor
The mouth of a river connects so that heat exchanger forms in parallel with radiator.
Transmission oil temperature control system described in the utility model, can fit according to the different running environment of electromotor and water temperature
When adjust gearbox oil temperature by heat exchange between engine coolant and transmission oil, when both having achieved cold start-up pair
The heating of transmission oil, effective cooling when also achieving heavy-duty service to transmission oil, it is ensured that variator
Lubricating oil has optimal operating viscosity, so as to reduce oil consumption.In addition, the system can also solve existing oil cooler to be designed at starting
Problem in machine radiator, can effectively reduce heat sink size.
Description of the drawings
Fig. 1 is the cooling system schematic diagram of existing transmission oil；
Fig. 2 is the structural representation of the system.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, and following examples are only used for solving
This utility model is released, the restriction to this utility model protection domain is not constituted.
Transmission oil temperature control system as shown in Figure 2, including electromotor 1, radiator 4, heat exchanger 5, oil pump 3 and adjusts
Warm device 6.
The heat exchanger 5 is used for the heat exchange for realizing transmission oil and engine coolant, in the heat exchanger
There are the first and second two fluid passages, the fluid media (medium) in two fluid passages in heat exchanger to carry out heat exchange, its
The entrance and exit of middle first fluid passage is connected to form lubrication oil circulation loop with the oil pump 3, by the oil pump 3 by speed change
Lubricating oil in device 2 is pumped in the first fluid passage of heat exchanger 5.
The engine water outlet is divided into two-way, connects with the second fluid feeder connection of heat exchanger 5 all the way, and this second
The outlet of fluid passage is connected with the water inlet of electromotor 1 again.Another road is connected with radiator inlet after thermoregulator 6, radiating
The outlet of device 4 is again connected with the water inlet of electromotor so that heat exchanger 5 formed with radiator 4 in parallel.
The operation principle of said system is：
When engine cold-start and cold operation, the thermoregulator 6 blocks state, electromotor 1 and Re Jiao in cut out
Parallel operation 5 forms partial circulating, and coolant water temperature is quickly raised, transmission oil entered by the heat exchange in heat exchanger
Row heating, accelerates the temperature rise of lubricating oil, reduces lubricating oil viscosity, reduces oil consumption so as to reducing friction loss and having reached
Purpose.
When electromotor is in big load condition, variator lubrication temperature is raised comparatively fast, if lubricating oil temperature is higher than to start
During machine water temperature, heat exchange is carried out by heat exchanger 5, to reduce the temperature of transmission oil, it is ensured that lubricating oil is in optimal work
Make viscosity.During long-play, engine water temperature rise causes thermoregulator 6 to open conducting, and coolant is dissipated by radiator 4
Heat, now engine water outlet be divided into two branch roads being in parallel, return to electromotor 1 through heat exchanger 5 all the way, another road is through radiating
Device 4 returns to electromotor 1, it is generally the case that flow of the flow of heat exchanger branch road much smaller than radiator branch.
It can be seen that, said system can be heated to transmission oil in low temperature, again can be to lubrication in high temperature
Oil is cooled down, so as to ensure that lubricating oil is stored in optimum working temperature well.
