Description
Technical Field
The utility model relates to an empty filter of motorcycle.
Background
In recent years, the noise control regulation is continuously revising the noise limit of the motor vehicle, and the intake noise is one of the main noise sources of the motorcycle and is gradually the key control object. An air filter is usually arranged on an engine of a motorcycle, the air filter with a noise elimination structure can play a role in reducing noise, and the use of the air filter becomes an effective method for controlling intake noise. In order to better control the intake noise of the air filter, it is necessary to make extensive research and improvement on the muffling structure of the air filter.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides an air filter of a motorcycle, which controls the air inlet noise through an extended air inlet channel.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an empty filter of making an uproar falls in motorcycle, includes the left casing that is equipped with the air inlet, the right casing that is equipped with the gas outlet, presss from both sides between left casing and the right casing and is equipped with filter element group spare, and left and right casing lid forms the inner chamber after closing and separates for clean chamber and dirty chamber through filter element group spare, and the dirty chamber of air inlet intercommunication, the clean chamber of gas outlet intercommunication, the gas outlet is located the front end of empty filter, and the air inlet setting is at left casing top, left side shells inner wall is equipped with and keeps off the wall and is located the air inlet below, keep off the wall and extend towards empty filter front end from the air inlet below, be located the rear of air inlet is equipped with the baffle, and the baffle is equipped with the siphunculus and divides.
The edge lateral wall of baffle is equipped with the slot, the wall of left side casing and filter element group spare corresponds the slot and is equipped with the installation muscle.
The utility model has the advantages that: the utility model discloses a communicating two parts around dirty chamber divide into through the baffle, first half air inlet below is equipped with the air drainage to dirty chamber front end that will get into the empty filter toward the baffle that empty filter front end extends, then the back half that gets into dirty chamber through the siphunculus of baffle gets into clean chamber after the filter core filters, clean gas after the filtration gets back to the front end by clean chamber rear end again and gets into the engine from the empty filter of gas outlet discharge, form longer admission passage through above-mentioned structure in limited empty filter inner chamber space and control the noise of admitting air, further promote the noise reduction of empty filter.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic, disassembled view of the present invention;
fig. 2 is a schematic exploded view of another perspective of the present invention;
fig. 3 is a schematic view of the gas circuit of the present invention.
Detailed Description
Referring to fig. 1 to 3, the noise reduction air filter for the motorcycle comprises a left shell 1 provided with an air inlet 11 and a right shell 2 provided with an air outlet 21, wherein a filter element assembly 3 is clamped between the left shell 1 and the right shell 2, an inner cavity is formed after the left shell and the right shell are covered and is divided into a clean cavity 5 and a dirty cavity 6 through the filter element assembly 3, the air inlet 11 is communicated with the dirty cavity 6, and the air outlet 21 is communicated with the clean cavity 5; the air outlet 21 is positioned at the front end of the air filter, the air inlet 11 is arranged at the top of the left shell 1, and dust or other air impurities entering the air filter can be effectively reduced by air entering from the top of the air filter. A baffle wall 7 is arranged on the inner wall of the left shell 1, and the baffle wall 7 extends from the lower part of the air inlet 11 to the front end of the air filter; a partition plate 8 is arranged behind the air inlet 11 to divide the dirty cavity 6 into a front part and a rear part, and the front part and the rear part are communicated through a through pipe 81 on the partition plate 8, so that noise can be better controlled; when air enters the air filter from the air inlet 11, the air can directly impact the baffle wall 7 below the air inlet 11 and flows to the front end of the dirty cavity 6 along the wall surface of the baffle wall 7, then the air turns around to flow to the rear end and flows into the rear half part of the dirty cavity 6 through the through pipe 81 of the partition plate 8, the through pipe 81 can better guide the air to a region with a larger distance in the rear half part, the filter element 31 of the filter element assembly 3 is positioned in the rear half part of the dirty cavity 6, all the inflowing air can enter the rear part of the clean cavity 5 after being filtered by the filter element 31 and then is discharged from the air outlet in the front end of the clean cavity 5 to enter the engine, a longer air inlet channel is formed in the limited inner cavity space of the air filter through the structure to control air inlet noise, and the noise.
The edge side wall of the partition plate 8 is provided with an insertion slot 82, and the wall surfaces of the left shell 1 and the filter element assembly 3 are provided with mounting ribs 9 corresponding to the insertion slot 82. When the partition board 8 is installed, the installation ribs 9 are inserted into the slots 82, so that the partition board 8 is installed and fixed, and the installation edge of the partition board 8 is sealed.
