Air filter cleaner structure for two-wheel motor vehicle

Abstract

The invention provides an air filter cleaner structure of two-wheeled vehicles, which can improve the working ability of cleaning in a secondary combustion chamber, and enhance assembly performance of the air filter cleaner in order to add the degree of freedom of design. In the invention, an air filter cleaner shell (81) includes a jointing structure for jointing the air filter cleaner (84) to a main body of the shell (82), and the jointing face (81A) of the main body of the shell and the air filter cleaner is flat in an orthogonal direction, a connection pipe (48) communicated with engine side is connected with the main body of the shell to point at a plane (81B) through the jointing face; a separator for forming the secondary combustion chamber (106) is installed on the main body of the shell in a manner of free assembly and disassembly so as to cover connection portion (105) of the connection pipe and oppose to an end part (8b) of the connection pipe; a cylindrical air filter cleaner element (103) is detachably embedded in an element connection hole (101b) provided on the separator (101).

Description

technical field [0001] The present invention relates to an improvement in the structure of an air filter for a two-wheeled motor vehicle. Background technique [0002] As a conventional air cleaner structure for motorcycles, a structure in which a sub-combustion chamber is provided in an air cleaner case is known (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2001-90623. [0004] FIG. 3 , FIG. 4 , and FIG. 6 of Patent Document 1 will be described below. [0005] The air cleaner housing 42 is divided into an element front chamber 44 as a polluted side and an element rear chamber 45 as a clean side by a filter element 43, and a part of the space on the clean side is separated by a partition wall 46 to form a secondary combustion chamber 48, The blow-by gas hose 34 for reducing the blow-by gas from the crankcase of the engine is connected to the sub-combustion chamber 48, and the sub-combustion cha...

Problems solved by technology

[0006] The auxiliary combustion chamber 48 is provided with a combustion chamber cover 64, which is fixed by screws 65, 65 so that the auxiliary combustion chamber 48 can be opened and closed. However, the blocked opening is arranged on the flat auxiliary combustion chamber by the combustion chamber cover 64. Therefore, for example, when cleaning the inside of the sub-combustion chamber 48, it is difficult for hands to enter the inside and it is difficult to carry out work.
