A cooling system for a hybrid four-wheel drive vehicle

Abstract

The invention discloses a hybrid power four-wheel drive vehicle cooling system, comprising an electric drive cooling cycle and an engine cooling cycle. Cooling liquid in the electric drive cooling cycle is driven by a water pump in the electric drive cooling cycle, and the cooling liquid passes a rear drive motor and a front drive motor as well as a radiator I, then passes a power supply module, and finally flows back to the water pump; cooling fluid in the engine cooling cycle is driven by a water pump built in an engine, and the cooling fluid passes the engine and a radiator II, and then flows back to the engine; the radiator I and the radiator II are an integrated part. The two cooling cycles are adopted, thus the problem that the temperature of the engine cannot be compatible with other parts is solved, and the cooling requirement of each component in the system is met; the two radiators are integrated, so that the size of the radiators is reduced effectively, and arrangement on the vehicle is convenient; spare parts of the complete set of the cooling system are decreased, and thus the reliability of the cooling system is improved.

Description

Technical field [0001] The invention relates to the technical field of hybrid power vehicles, and in particular to a cooling system for a hybrid four-wheel drive vehicle. Background technique [0002] Hybrid vehicles are restricted by the space of the front cabin, and the volume and power of traditional front-drive motors are restricted. Therefore, adding a rear-drive motor to drive the rear wheels alone can alleviate this restriction and effectively increase the power of the motor. The electric motor on the hybrid four-wheel drive vehicle can drive the entire vehicle alone, and can also assist the engine at medium and high speeds. The rear drive system of the vehicle includes a rear drive motor and a rear drive motor controller; the front drive system includes an engine, a front drive motor and a front drive motor controller. [0003] These key components in hybrid four-wheel drive vehicles have requirements for operating temperature, and the difference is large, which causes a s...

AI Technical Summary

Problems solved by technology

[0003] These key components in the hybrid four-wheel drive have requirements on the working temperature, and the difference is large, which makes a single cooling system unable to meet; at the same time, because the position of the rear drive motor is far away from the front cabin, the choice of water pump is more important. High requirements; Compared with pure electric vehicles, it is more complicated, and the requirements for layout are also increased accordingly
