Range-extended electric automobile oil suction pipe

Technical Field

The utility model relates to an automobile parts field, more specifically says, it relates to an increase journey electric automobile and inhale oil pipe.

Background

In order to reduce the frictional resistance between the relatively moving parts in the engine and reduce the abrasion of the parts, the engine oil is continuously delivered to the friction surfaces of the moving parts to form a lubricating oil film for lubrication. The engine oil itself contains a certain amount of gums, impurities, moisture and additives. Meanwhile, in the working process of the engine, metal abrasive dust is brought in, sundries in the air enter, and engine oil oxides are generated, so that the sundries in the engine oil are increased gradually. If the engine oil directly enters the lubricating oil circuit without being filtered, sundries contained in the engine oil can be brought to the friction surface of the kinematic pair, the abrasion of parts is accelerated, and the service life of the engine is shortened. The engine oil strainer is used for filtering impurities, colloid and water in the engine oil and conveying clean engine oil to each lubricating part. The invention requires increased oil filtration efficiency with a constant volume.

Compared with the original engine oil strainer, the extended-range electric automobile not only needs to meet the requirement of engine oil filtration, but also needs to consider the flow ratio of the oil inlet and the oil outlet 5, the filtration efficiency and the strength improvement before and after light weight.
