Abstract

The invention relates to a connecting structure for connecting an oil baffle plate and an oil sump of an engine and belongs to the technical field of automotive power units. The connecting structure comprises an oil sump body and the oil baffle plate, wherein an outer-layer boss is arranged at the outer edge of the top of the oil sump body, bolt holes are formed in a first flange surface of the outer-layer boss, an inner-layer boss is arranged on the inner wall of the oil sump body and is lower than the outer-layer boss, bolt holes are formed in a second flange surface of the inner-layer boss, the oil baffle plate is fixedly mounted on the second flange surface of the inner-layer boss, positioning structures for positioning the oil baffle plate are arranged on the inner wall of the oil sump body between the inner-layer boss and the outer-layer boss, mounting positioning plates are arranged on the oil baffle plate, and the oil baffle plate is stuck in the positioning structures by the mounting positioning plates and matched with the oil sump body. with the special oil baffle plate positioning structures, the connecting structure has the advantages that the mounting position of the oil baffle plate can be provided, the strength and the rigidity of the oil sump are greatly improved and the radiating area is reduced; and as the oil sump is of a layered structure, the noise is favorably reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile power devices, and in particular relates to a connection structure between an engine oil baffle and an oil pan. Background technique [0002] Most of the current engine oil pans are stamped thin-walled parts, which are mainly used to store engine oil and protect the internal moving parts of the engine. Thin-walled parts usually perform poorly in terms of NVH, and their strength and rigidity are slightly insufficient, and the oil baffle plate in the prior art is installed on the outer edge boss of the oil sump housing, and this installation structure causes relatively high noise. Contents of the invention [0003] The object of the present invention is to provide a connection structure between an engine oil baffle and an oil pan to address the above defects. [0004] The technical solution adopted by the present invention is: it includes an oil bottom shell and an oil baffle plate, an outer b...
