Oil filter cover structure

Abstract

The invention discloses an oil filter cover structure which comprises a cover body (1). The cover body (1) is of a step-shaped cylinder structure with a large upper part and a small lower part; a supporting lug (2) is arranged on the outer circumference of the upper step section of the cover body (1); a mounting through hole (2a) is arranged on the supporting lug (2); an oil duct (3) is arranged at the lower step section of the cover body (1); the inlet of the oil duct (3) is positioned on the outer circumference of the lower step section of the cover body (1); and the outlet of the oil duct (3) is positioned on the bottom surface of the cover body (1). The invention provides convenience for the maintenance and the replacement of filter elements, so that the operation of cleaning and replacing the filter elements is simple and quick, and the sealing performance and the dynamic balance of a crankcase are not influenced. The invention has the advantages of skilful concept, simple structure, easy implementation, good reliability, and the like.

Description

technical field [0001] The present invention relates to an engine component, and more particularly, to an oil filter cover on an engine. Background technique [0002] During the operation of the engine, the oil in the lubrication system will continue to become dirty. There are several sources of pollution: first, foreign impurities, such as dust in the air, enter the crankcase through the breathing pipe, fuel filler, etc.; Metal shavings from worn parts; and the products of the oxidation process of the oil itself, such as various organic acids, asphalt and carbides, etc.; and water leaking into the oil pan. These impurities promote wear and tear on parts, and the resulting corrosion can kill moving parts. The function of the oil filter is to filter out the above-mentioned harmful impurities in the oil, protect the components of the main engine, and prolong its service life. [0003] Traditional motorcycle engines generally use a centrifugal oil filter, which is installed o...

AI Technical Summary

Problems solved by technology

Since the centrifugal oil filter is located in the crankcase, when maintenance or replacement is required, the crankcase cover and the crankshaft must be disassembled, which is not only cumbersome to operate, but also has a large workload and low efficiency, and frequent disassembly and assembly may easily cause crankcase sealing. It will destroy the dynamic balance of the crankshaft and reduce the stability of the crankshaft. On the one hand, it will increase the vibration of the engine, and on the other hand, it will shorten the service life of the crankshaft.
