motorcycle air filter

Abstract

The invention discloses an air filter of a motorcycle. The air filter comprises an air filter box and a filter element assembly arranged inside the air filter box, wherein the air filter box is formed by welding or bonding of a left casing, a right casing and a filter element assembly fixing plate, the filter element assembly fixing plate is arranged between the two casings and used for installing the filter element assembly, edges of the left and right casings are aligned, the filter element assembly fixing plate is clamped between the edges of the left and right casings to divide the air filter box into a clean cavity on the right casing side and a dirty cavity on the left casing side, a through hole is formed in the filter element assembly fixing plate to enable the clean cavity to be communicated with the dirty cavity, the filter element assembly is sealed and fixed at the through hole, and an air filter cover plate is installed at an opening end of the left casing. The air filter of the motorcycle is simple in assembly technology, and the filter element assembly is not limited by a protection hood in the prior art, so that the filter element assembly can be manufactured as large as possible to satisfy requirements of air filtration; and meanwhile, the space of the dirty cavity inside the air filter is greatly enlarged, so that the air intake and the air filtration are facilitated, the maintenance period of the air filter is prolonged, and the daily maintenance cost of a user is reduced.

Description

technical field [0001] The invention relates to a motorcycle, in particular to a motorcycle air filter. Background technique [0002] As an important component of a motorcycle, the motorcycle air filter is used to filter and purify the air entering the motorcycle engine, and to filter out dust, sand, etc. in the air. The basic structure of the air filter includes the air filter box and the filter element assembly inside. After the outside air enters the dirty cavity of the air filter, it must be filtered by the filter element before entering the clean cavity, and is sent into the carburetor through the air outlet pipe of the clean cavity. Participate in the work of the engine. refer to Figure 5 , the air filter box in the prior art is composed of a housing 1' and a protective cover 2', the side wall of the housing is open, the filter element assembly is fixedly installed at the opening through the protective cover, and the cavity in the protective cover 2' is dirty cavity...

AI Technical Summary

Problems solved by technology

refer to Figure 5 , the air filter box in the prior art is composed of a housing 1' and a protective cover 2', the side wall of the housing is open, the filter element assembly is fixedly installed at the opening through the protective cover, and the cavity in the protective cover 2' is dirty cavity, on which an air intake pipe is arranged, and the cavity in the housing 1' is a clean cavity, on which an air outlet pipe is arranged; the air filter box with this structure, in order to ensure that the protective cover 2' and the filter element assembly inside For positioning and installation on the side wall of the housing 1', screw and sealing ring installation positions must be reserved, so that the design of the protective cover and the filter element assembly must be smaller than the side wall of the housing, resulting in a small volume of the dirty cavity, and the filter element It is also small, causing problems such as large air intake resistance and low air intake efficiency of the air filter, which is not conducive to air intake and filtration, especially when the external environment is dirty, it will make the dirty cavity easily filled with dust, which requires Increase the frequency of replacement and maintenance, causing inconvenience to users in daily maintenance and an increase in vehicle costs
