Problems solved by technology

Since the existing oil filter has only one link of centrifugal force to separate impurities, and motorcycles may have frequent acceleration and deceleration, the centrifugal force increases during acceleration, and the impurities can be reliably attached to the inner wall. If deceleration, the centrifugal force decreases. Impurities in the inner wall may come off the inner wall and enter the crankshaft with the lubricating oil, so the separation effect is limited, which is not conducive to maximizing the life of the engine through lubrication

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] see figure 1 , as can be seen from the figure, the motorcycle engine graded filter oil filter assembly of the present invention includes a filter rotor 1, a filter cover 2 and a crankshaft oil pipe 3, and the center of the filter rotor 1 has a stepped structure The cavity 4 and the filter cover 2 are fixedly connected to the end with a large inner diameter of the filter rotor cavity by screws. There is a mounting hole in the center of the filter cover, the crankshaft oil pipe is installed in the mounting hole and one end of the crankshaft oil pipe is located in the cavity, and the other end is located outside the cavity. Radial oil outlet 5.

[0015] In the present invention, a filter partition 6 is added in the filter rotor cavity 4, and the edge of the filter partition 6 is installed and fixed between the filter cover 2 and the end face of the filt...

Abstract

The invention discloses a classified filtering engine oil filter assembly for a motorcycle engine. The classified filtering engine oil filter assembly comprises a filter rotor, a filter cover and a crankshaft oil pass pipe. A filtering partition plate is arranged in a cavity of the filter rotor. The edge of the filtering partition plate is fixedly installed between the filter cover and the end face of the filter rotor. The middle portion of the filtering partition plate is hunched in the direction away from the crankshaft oil pass pipe so that a secondary scrap containing cavity can be formed in the hunched portion. Space between the other parts of the filtering partition plate except for the hunched part and the filter cover forms a primary scrap containing cavity. A plurality of primary oil pass holes paired with the primary scrap containing cavity are uniformly formed in the circumference, close to the edge, of the filtering partition plate. Secondary oil pass holes paired with the secondary scrap containing cavity are formed in the center position, corresponding to the bottom of the secondary scrap containing cavity, of the filtering partition plate. By means of classified filtering, the lubricating oil impurity separation effect is improved, and the engine can work better in the lubricating working state of the lubricating oil.

Description

technical field [0001] The invention relates to an oil filter, in particular to a motorcycle engine graded filter oil filter assembly, which belongs to the technical field of oil filters. Background technique [0002] During the working process of the engine, metal wear debris, dust, carbon deposits and colloidal deposits oxidized at high temperatures, water, etc. are continuously mixed into the lubricating oil. There is an oil filter on the engine, and the function of the oil filter is to filter out these mechanical impurities and colloids to keep the lubricating oil clean and prolong its service life. The oil filter should have strong filtering ability, small flow resistance and long service life. [0003] The oil filter is usually assembled on the engine crank rod assembly, which rotates with the crankshaft. Its working principle is: lubricating oil enters the oil filter through the oil inlet hole on the crankcase cover, and the oil filter generates centrifugal force du...
