Problems solved by technology

[0007] However, in the air intake device of the above-mentioned Patent Document 1, when it is desired to increase the length of the air intake passage to increase the low-speed torque, since the connecting pipe protruding forward from the front surface of the air cleaner is between the upper part of the engine and the The throttle area is connected, so it is difficult to increase the length of the intake passage at the part of the connecting pipe exposed from the air filter to the outside. Therefore, in order to increase the length of the intake passage, it is necessary to install the connecting pipe on the air filter Longer extended configuration
However, in the case where the connecting pipe is extended in the air cleaner in this way, it is difficult to install the connecting pipe at the time of assembling, which causes a problem in operability.

[0071] Next, use Figure 6 ~ Figure 8 , the second embodiment of the present invention will be described. The difference between this embodiment and the first embodiment mainly lies in the shape of the air cleaner, so the following description will focus on the differences, and the description of the common points with the first embodiment will be omitted. symbol to represent.

[0072] The air cleaner 65 in the present embodiment includes: a casing member 67 disposed with the opening facing forward, and having an intake duct 66 integrally provided at the rear portion facing rearward; Figure 7 ) The cover member 69 that fits with the housing member 67. Such as Figure 8 As shown, the air intake duct 66 is formed so as to penetrate in the front-rear direction at the right side in the vehicle width direction above the rear portion of the housing member 67 , and forms an air inflow path with a rectangular cross-section. More specifically, the air intake duct 66 is formed such...

Abstract

The present invention discloses an aspirating apparatus of ride type vehicle that can guarantee length of an aspirating passage on an outward protruding position from an air filter in a connection pipeline without extending the connection pipeline in the air filter, and can maintain the operation performance and improve the low-speed torsion of an engine. In the aspirating apparatus of ride type vehicle, an air filter (35) is set above the engine and below the front end of a main framework (10); a throttle area(33) is set behind a suction port (31) of the engine; the connection pipeline (34) extends backwards out of the connection part that is connected with the throttle area(33) and is bended in a U-shape, and extends frontwards to connect the air filter (35).

Description

technical field [0001] The present invention relates to an air suction device for straddle type vehicles. Background technique [0002] Patent Document 1 discloses an air intake device for a motorcycle that is mounted on a motorcycle including a vehicle frame and an engine, and supplies combustion air to the engine. The main frame extends in the front-rear direction, and the engine has forward-tilted cylinders, and is supported by the vehicle frame so as to be located below the main frame. [0003] The air intake device of the motorcycle includes: an air cleaner disposed above the rear of the forward-tilting cylinder; a connecting pipe protruding forward from the front surface of the air cleaner; a connecting pipe connected to the connecting pipe. Throttle area; an intake pipe connected to the throttle area and bent forward and downward, and connected to the intake port in the engine that opens upward, wherein the air filter is ensured due to the space between the engine an...
