Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and particularly relates to an oil pan. Background Art

[0002] For oil-cooled motors, or oil-cooled and oil-lubricated speed reducers, and oil-cooled multi-in-one electric drive systems, in order to ensure reliable flow rate, more and more electronic oil pumps are selected. That is, the oil pump extracts oil from the oil pan structure for storing and reserving oil, and applies a certain pressure to make the oil flow through the oil-cooling system at a certain flow rate.

[0003] The oil extraction port is usually only located on one side of the oil pan. When the attitude of the whole vehicle changes, the coolant in the usually designed oil pan will also change its flow direction along with the attitude of the whole vehicle, so that the liquid level of the oil in the oil pan cannot always cover the oil extraction port, resulting in the oil pump sucking air. When the oil pump sucks air, the oil pump inhales a mixture of oil and air, and the actual flow rate of the cooling oil will be greatly discounted, which will have an adverse impact on cooling and lubrication.
