Chassis type air purifier system for motorcycle

Abstract

The invention provides a chassis type air purifier system for a motorcycle, comprises an air purifier case installed on a lower frame on the rear upper of a from mudguard, for supplying air to an engine. the air purifier case comprises: a case with an opening which can be opened forwards in a front-back direction; a cover unit for closing the opening the of the case; and an air filter with a filtration unit, which is arranged on a connection part between the case and the cover unit for dividing the internal part of the air purifier case into a purified side and a dirt side, wherein the filtration unit is maintained by a maintaining plate. The cover unit comprises a gap concave part, so as to extend from at least one side of the cover unit along a vertical direction, thereby partially insolating the dirt side and forming an air inlet passage to introduce air to the lower part form an air inlet. Viewed from the front of the vehicle, the filtration unit of the air purifier is arranged to deflect to the upper of the air purifier case and is installed on the maintain plate.

Description

technical field [0001] The present invention relates to an air purifier system of a motorcycle provided with an underbone frame structure equipped with an under frame extending rearwardly and downwardly from a head pipe, the air purifier system comprising an air A cleaner box is mounted on the lower frame above the rear of the front fender. Background technique [0002] In a motorcycle provided with an underframe frame (for convenience of description, hereinafter may be referred to as "underframe (type) motorcycle"), the underframe extends rearward and downward (i.e., rearward) from the head tube, which is The front wheels are pivotally supported in such a manner that the front wheels can turn left and right; the engine is installed in the lower part of the lower frame; a front fender for covering the front wheels is arranged in front of the engine; The air cleaner box of the air cleaner system disclosed in Patent No. 8-135528) is fixedly installed on the lower frame and ab...

Problems solved by technology

[0009] Therefore, with the structure of the conventional air cleaner system 100 described above, there is a concern that the flow channel in the lower region of the dirty side 107 has a reduced cross-sectional area, thereby hindering the flow from the air inlet channel 111 to the air filter 104. The air flow of the filter unit 105, which may lead to increased suction resistance, thereby reducing the suction efficiency of the air cleaner system 100
