A kind of oil sump and engine

Abstract

The invention belongs to the technical field of engine oil circulation, and discloses an oil pan and an engine, wherein the oil pan comprises an oil pan body and an annular baffle assembly; the annular baffle assembly is arranged at the bottom of the oil pan body; and the annular baffles comprise flow passages communicated with the inside and outside of the annular baffle assembly. Flow passages are arranged, by the oil pan, on the annular baffle assembly to enable the oil between the oil pan body and the annular baffle assembly to be sucked by a suction filter through the flow passages to complete the circulation of the engine oil; and meanwhile, the annular baffle assembly is arranged outside an oil suction cover of the suction filter in an annular manner to enable the annular baffle assembly to store a certain amount of engine oil for the suction filter to suck the engine oil in a bumpy and inclined state, so that idling of an engine oil pump is avoided, and the service life of theengine oil pump is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of engine oil circulation, in particular to an oil pan and an engine. Background technique [0002] The engine oil is generally stored in the oil pan. After filtering the larger particles in the oil through the filter set above the oil pan, the clean oil enters the oil pump, and then uses the oil pump to spray the oil on each transmission. On the assembly, the oil falls freely under its own gravity and returns to the oil pan. [0003] In order to ensure that the oil falls back into the oil pan as much as possible, the oil pan generally has a larger open end. However, with this structure, due to the limited space for the oil pan on the vehicle, especially for some mining vehicles on sloped and bumpy road conditions such as uphill and downhill, the oil can easily flow to both ends of the oil pan. If the inclination angle exceeds the limit angle, the filter will be directly exposed above the oil level in the ...

Problems solved by technology

However, with this structure, due to the limited space for the oil pan on the vehicle, especially for some mining vehicles on sloped and bumpy road conditions such as uphill and downhill, the oil can easily flow to both ends of the oil pan. If the inclination angle exceeds the limit angle, the filter will be directly exposed above the oil level in the oil pan, so that the filter cannot absorb the oil normally, resulting in idling of the oil pump, seriously affecting the service life of the oil pump

At the same time, the filter cannot supply enough engine oil to the engine, so that the engine oil supply is insufficient, resulting in serious wear and aging of various transmission components
