Abstract

A double-motor oil cooling system comprises an oil storage cavity and a circulating cooling oil way, each motor is provided with the circulating cooling oil way, the circulating cooling oil way comprises an oil pump, the input end of the oil pump is communicated with the oil storage cavity through a suction filter, and the output end of the oil pump is provided with a filter pressing filter. The output end of the filter pressing filter is communicated with the heat exchanger, the oil outlet end of the heat exchanger enters the motor rotor, the motor stator and the planet wheel through oil pipes, and a cooling oil way in the motor rotor is communicated with a cooling oil way in the motor stator. The cooling oil way outlet in the motor stator and the cooling oil way outlet in the planet wheel are communicated with the oil storage cavity. Cooling oil of the two motors and cooling oil of the transmission share the oil storage cavity, one filter for suction filtration, the oil pump, two filters for press filtration and the heat exchanger are independently applied to cooling of each motor, and therefore the cleanliness of the cooling oil of the motors is guaranteed.
