Abstract
The utility model discloses an automatic derailleur electric machine cooling device, include: casing, the stator of motor install in in the casing, be equipped with main oil gallery and branch's oil duct on the casing, the main oil gallery communicates with each other with branch's oil duct, branch's oil duct opening is in the inner peripheral surface of stator mounting hole. Through main oil gallery and branch's oil duct, force to spout the winding to motor stator with transmission oil to realize motor stator's oil cooling.
Description
Technical field
The utility model relates to automatic transmission technical field, particularly relates to a kind of device cooled by the motor of hybrid vehicle automatic transmission.
Background technology
Hybrid vehicle, refer to oil-electric vehicle (HybridElectricVehicle), namely adopt traditional oil engine (diesel engine or petrol motor) and electric motor as propulsion source, also the engine having uses other alternative fuel, such as compressed natural gas, propane and alcohol fuel etc. through transformation. Along with the measure of countries in the world environment protection is more and more stricter, motor vehicle driven by mixed power becomes an emphasis of automotive field research and development due to features such as it is energy-conservation, low emissions.
In order to adapt to this kind of trend, Chinese invention patent application CN104776176A, disclose a kind of automatic transmission (AT), two axle systems, three spurn wheel groups, three planetary set and some gear shift units are installed side by side in variator housing, wherein, an axle system is positioned at power input side, comprises the first axle for input power, another axle system is positioned at Power output side, comprises the 2nd axle for outputting power; Being provided with a motor in variator housing, the rotor of motor is fixedly connected with the input terminus of the first axle, and the stator of motor is installed on housing; Being provided with a clutch coupling between engine flywheel and motor, the outer hub of clutch coupling is fixedly connected with the rotor of motor, and the interior hub of clutch coupling is fixedly connected with engine flywheel.
Operationally, the winding at its stator two ends can produce heat to motor, if do not cooled, will affect the reliability of vehicle. Air cooling effect is not good, and water-cooled needs to add in addition pipeline and system.
Practical novel content
Technical problem to be solved in the utility model is: provides a kind of automatic transmission motor refrigerating unit, realizes the oil cooling of motor stator by simple structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of automatic transmission motor refrigerating unit, comprising: housing, and the stator of motor is installed in described housing; Described housing is provided with main oil gallery and branch's oil duct, and described main oil gallery communicates with branch oil duct, and described branch oil duct is opened on the inner peripheral surface of stator open holes.
Further, it being provided with transmission oil in described housing, described motor rotor is lower than the liquid level of described transmission oil.
After have employed technique scheme, the beneficial effects of the utility model are:
1) by main oil gallery and branch's oil duct, transmission oil is forced the winding spraying to motor stator, thus realizes the oil cooling of motor stator.
2) being arranged in housing by transmission oil and keep certain liquid level, motor rotor, when rotating, can stir transmission oil, realize the cooling to motor stator two ends winding by the mode of spray lubrication.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the utility model embodiment;
Wherein:
1-housing; 11-main oil gallery; 12-branch oil duct; 2-stator; 3-rotor.
Embodiment
Below in conjunction with drawings and Examples, the utility model is illustrated further.
As shown in Figure 1, this variator is suitable for hybrid vehicle, and the stator 2 of motor is installed in the stator open holes of housing 1, and housing 1 is provided with main oil gallery 11 and branch's oil duct 12, main oil gallery 11 communicates with branch oil duct 12, and branch's oil duct 12 is opened on the inner peripheral surface of stator open holes.
Being provided with transmission oil in housing 1, the liquid level of transmission oil suitably to be controlled, and the rotor 3 of motor, lower than the liquid level of described lubricating oil, so that being stirred by transmission oil when rotating, and makes it to be splashed on the stator winding of motor, it is to increase the cooling performance of motor.
Claims (2)
