Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engine accessories, and particularly relates to an oil filter for a motorcycle engine. Background Technique
[0002] During the normal operation of the engine, various components in the engine need to be lubricated by oil to reduce wear during use and extend the service life. During the operation of the engine, the oil is recycled, and impurities such as metal debris generated by friction between components, dust entering the engine interior, carbon deposits oxidized at high temperatures, and oxidation products of the oil itself will mix into the oil. Over time, these impurities will affect the lubrication effect of the oil, and even affect the normal operation of the engine and damage the engine. Therefore, an oil filter needs to be set between the oil pump and the moving parts to filter the impurities in the oil and ensure the cleanliness of the supplied oil.
[0003] For example, an oil filter (publication number: CN217652804U) includes a housing, a filter assembly, and a bypass valve. The filter assembly and the bypass valve are both located inside the housing. The housing inlet is connected to the housing outlet through the bypass valve. The bypass valve includes a valve body, a valve plate, and a rubber elastic member. One end of the rubber elastic member abuts against the valve body, and the other end abuts against the valve plate. The rubber elastic member can change its elastic modulus with temperature changes; aiming at the problem that the bypass valve is prone to misopening under low-temperature operating conditions, by using the characteristic that the rubber elastic member changes its elastic modulus with temperature, the opening pressure of the bypass valve changes with the ambient temperature, the opening pressure of the bypass valve at low temperature is increased, the probability of misopening of the bypass valve during operation of the filter in a low-temperature environment is reduced, and the wear of components is reduced.
[0004] Based on the retrieval of the above patent and the combination with the equipment in the prior art, it is found that the disassembly and replacement of the filter assembly of the above equipment are relatively troublesome during application. Since the internal filter assembly filters the lubricating oil for a long time, a large amount of impurities adhere to the surface of the filter assembly, resulting in an increasing resistance of the filter and a reduction in the filtering effect on the oil. Therefore, it is necessary to disassemble it to clean the filter assembly. The troublesome disassembly of the filter causes inconvenience to the cleaning of the filter assembly and cannot meet the needs of users. Therefore, we need to propose an oil filter for a motorcycle engine. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0024] An oil filter for a motorcycle engine includes an outer shell 1, a filter element 2 is installed inside the outer shell 1, a check valve 6 is installed on the top of the filter element 2, a bypass valve 13 is installed at the bottom of the filter element 2, the top of the outer shell 1 is detachably installed with a shell cover 3, an oil outlet 4 is provided at the center of the shell cover 3, and a plurality of groups of oil inlets 5 are arranged in a circular array outside the oil outlet 4 of the shell cover 3;
[0025] A ring-shaped fixing plate 14 is fixedly installed on the outer wall of the top of the outer shell 1, an arc-shaped insertion plate 16 is fixedly installed at the bottom of the shell cover 3, and the arc-shaped insertion plate 16 and the ring-shaped fixing plate 14 are bolted and fixed by a bolt 17, which is convenient for disassembling and assembling the shell cover 3 through the bolt 17, and thus convenient for replacing or cleaning the filter element 2 inside the outer shell 1.
[0026] A butt joint pipe 8 is integrally formed at the bottom of the shell cover 3 at the oil outlet 4, the bottom of the butt joint pipe 8 is connected to the top of the check valve 6, and a sealing ring 9 is sleeved at the connection between the butt joint pipe 8 and the check valve 6. The seal between the check valve 6 and the butt joint pipe 8 is achieved through the sealing ring 9, which is convenient for preventing the reverse flow of oil when the oil pump stops working through the check valve 6, thereby protecting the oil pump and the engine from damage.
[0027] The outer wall of the filter element 2 is equidistantly sleeved with three magnetic rings 7 with magnetism, and a number of arc-shaped notches 12 are formed in an annular array on the outer wall of the magnetic ring 7, so that the three magnetic rings 7 can adsorb magnetic impurities in the engine oil entering the housing 1, preventing the magnetic impurities in the engine oil from entering the lubrication system along with the engine oil and damaging engine components. At the same time, the arc-shaped notches 12 provided on the outer wall of the magnetic ring 7 do not hinder the flow of the engine oil.
[0028] An installation groove 10 is formed in the inner bottom of the housing 1, and a spring 11 is fixedly installed inside the installation groove 10. One end of the spring 11 is connected to the valve core of the bypass valve 13. When the filter element 2 inside the housing 1 is blocked after long-term use and the oil pressure increases, the spring 11 will deform under the action of the oil pressure, and then push the valve core of the bypass valve 13 to open, so that the engine oil can directly flow into the main oil passage of the engine by bypassing the filter element 2 to ensure the lubrication requirement of the engine.
[0029] Two arc-shaped insertion grooves 15 are symmetrically formed on the annular fixing plate 14, and two arc-shaped insertion plates 16 are respectively slidably inserted into the two arc-shaped insertion grooves 15, so as to limit the arc-shaped insertion plates 16 through the arc-shaped insertion grooves 15 and enable the housing cover 3 to stably cover the housing 1.
[0030] A stepped groove for the bolt 17 is formed on the side wall of the annular fixing plate 14. One end of the bolt 17 passes through the stepped groove and is threadedly connected to the inside of the arc-shaped insertion plate 16. The bolt 17 is an internal hexagonal bolt, which is convenient for bolt-connecting and fixing the arc-shaped insertion plate 16 through the bolt 17.
[0031] Working principle: When the present utility model is in use, the two arc-shaped insertion plates 16 at the bottom of the housing cover 3 are inserted into the two arc-shaped insertion grooves 15 on the annular fixing plate 14, and the arc-shaped insertion plates 16 and the annular fixing plate 14 are bolt-connected and fixed through the bolt 17. The housing cover 3 can be disassembled and assembled through the bolt 17, so as to facilitate the replacement or cleaning of the filter element 2 inside the housing 1;
[0032] Through the cooperation of the three magnetic rings 7 on the outer wall of the filter element 2, the filter element 2 filters the engine oil. The three magnetic rings 7 can adsorb magnetic impurities in the engine oil entering the housing 1, preventing the magnetic impurities in the engine oil from entering the lubrication system along with the engine oil and damaging engine components. At the same time, the arc-shaped notches 12 provided on the outer wall of the magnetic ring 7 do not hinder the flow of the engine oil.
[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
