Oil pan

Abstract

The invention discloses an oil pan comprising a shell, an oil baffle and a one-way communicating component, wherein the shell is the oil pan body, and is provided with a chamber; the oil baffle is arranged in the chamber in an up-and-down extension mode, and used for dividing the chamber into a first chamber and a second chamber; the first chamber corresponds to an oil suction port, and the one-way communicating component is arranged on the oil baffle, and used for communicating the first chamber with the second chamber unidirectionally; and the communicating flow direction of the one-way communicating component is that oil flows to the first chamber from the second chamber. The shell, namely the oil pan, is internally provided with the oil baffle; when an automobile inclines, the oil in the oil pan can be gathered around the oil suction port through the oil baffle, and the oil level remains above the oil suction port; the size of the oil pan can be decreased through the design, and the overall arrangement of an engine is facilitated; and the oil baffle is further provided with the one-way communicating component, so that the oil flows to the first chamber from the second chamber, and is gathered in the first chamber as much as possible.

Description

technical field [0001] The invention relates to the technical field of engine crankcases, in particular to an oil pan. Background technique [0002] The engine needs oil to lubricate during normal operation. The oil pan is the main oil storage part of the engine. The shape of the oil pan depends on the requirements of the vehicle space layout in addition to meeting the assembly requirements of the engine itself. The shape directly determines the oil storage capacity of the oil pan. [0003] During the normal driving process of the car, there will be different attitudes such as climbing, downhill, sideways, etc., and the engine oil is in a liquid state. No matter what state the car is running in, the oil level will always remain level. The worst conditions are designed for the boundary. Usually, the oil pan is designed with the car tilting 30° in the eight directions of forward, rear, left, right, left front, right front, left rear and right rear respectively as the maximum...

AI Technical Summary

Problems solved by technology

[0004] In order to solve this problem, the existing oil pan adopts the method of increasing the depth of the oil pan and lowering the position of the oil suction port, resulting in an increase in the volume of the engine, which in turn causes the engine to interfere with the layout of the vehicle or even cause the engine to fail to match, etc. question
