Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, the motor of the present embodiment comprises cooling system, described cooling system comprises: water pump 1, body water jacket 2, flow path control gear 3 and machine oil cooler 4, connect into closed loop by pipeline (mark) successively, flow path control gear 3 is connected with the water outlet of body water jacket 2, the water inlet of body water jacket 2 respectively by two pipelines.
When motor moves to the different stages, the coolant temperature of body water jacket 2 water outlet is different.Therefore, according to the coolant temperature of body water jacket 2 water outlet, can differentiate which stage motor moves to.In the present embodiment, when the coolant temperature of definition body water jacket 2 water outlet is the first temperature range, motor enters startup or low load stage; When the coolant temperature of definition body water jacket 2 water outlet is the second temperature range, motor moves to high-speed high-load or low speed high load stage; When the coolant temperature of definition body water jacket 2 water outlet is the 3rd temperature range, motor enters rotating speed and load boost phase gradually.
Flow path control gear 3 controls the first cooling passage and/or the circulation of the second cooling passage according to the coolant temperature of body water jacket 2 water outlet:
When the coolant temperature of body water jacket 2 water outlet is the first temperature range, described first cooling passage circulation, to raise the oil temperature in machine oil cooler 4;
When the coolant temperature of body water jacket 2 water outlet is the second temperature range, described second cooling passage circulation, to reduce the oil temperature in machine oil cooler 4;
When the coolant temperature of body water jacket 2 water outlet is the 3rd temperature range, described first cooling passage and the second cooling passage circulate simultaneously, to maintain the oil temperature in machine oil cooler 4.Described 3rd temperature range is greater than the first temperature range, is less than the second temperature range.
Described first cooling passage flows through successively: the water inlet of water pump 1, body water jacket 2, the water outlet of body water jacket 2, flow path control gear 3, machine oil cooler 4.When cooling liquid is along described first cooling passage flowing, cooling liquid flows to water inlet, the water outlet of body water jacket 2, flow path control gear 3, the machine oil cooler 4 of body water jacket 2 successively from the outlet of water pump 1.When cooling liquid flows through body water jacket 2, cooling liquid can absorb the heat that engine operation produces, thus makes engine cooling.Therefore, during engine operation, the cooling liquid of body water jacket 2 water outlet has relatively high temperature.
As can be seen here, at engine start or when operating to low load stage, can under the control action of flow path control gear 3, cooling liquid is flowed along the first cooling passage, so, the cooling liquid flowing into machine oil cooler 4 has relatively high temperature because flowing through body water jacket 2, the cooling liquid with comparative high temperature can transfer heat to the machine oil in machine oil cooler 4 when flowing through machine oil cooler 4, machine oil is increased to fast temperature required, shorten the warm-up period of motor, decrease frictional work and the oil consumption of engine friction pair.
It should be noted that, in the present invention, cooling liquid flows through body water jacket 2 and refers to that cooling liquid flows to the water outlet of body water jacket 2 from the water inlet of body water jacket 2.

Meanwhile, when motor moves to high-speed high-load or low speed high load stage, can under the control action of flow path control gear 3, cooling liquid be made to flow along the second cooling passage.So, the cooling liquid flowing into machine oil cooler 4 has relatively low temperature because not flowing through body water jacket 2, can the heat of machine oil in absorption machine oil cooler 4 when cooling liquid flows through machine oil cooler 4, and then can effectively machine oil be cooled to temperature required.
Further, motor enter rotating speed and load gradually boost phase time, cooling liquid can be made simultaneously along the first cooling passage and the flowing of the second cooling passage under the control action of flow path control gear 3.So, flow in the cooling liquid of machine oil cooler 4, part cooling liquid has relatively high temperature because flowing through body water jacket 2, another part cooling liquid has relatively low temperature because not flowing through body water jacket 2, therefore, flow into machine oil cooler 4 coolant temperature can not too high also can not be too low, and then the machine oil in machine oil cooler 4 can be maintained temperature required, to reduce frictional work and the oil consumption of engine friction pair.
