本発明は自動二輪車の吸気消音装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an intake silencer for a motorcycle.
一般に、荒地を走行することがあるオフロードタイプの
自動二輪車においては、排気消音装置を車輪で跳上げた
小石や転倒から保護する必要がある。そのため、従来、
車体の一側に排気消音装置を配設し、この排気消音装置
をサイドカバーで覆っている。Generally, in off-road type motorcycles that travel on rough terrain, it is necessary to protect the exhaust muffler from pebbles thrown up by the wheels and falls. Therefore, conventionally,
An exhaust silencing device is installed on one side of the vehicle body, and the exhaust silencing device is covered with a side cover.
しかし、このような構造では、車体中心から見た左右の
外観上のバランスをとるために、排気消音装置が配設さ

と対称に何らの機能ももたないサイドカバーを設けなけ
ればならない。However, in such a structure, in order to balance the appearance between the left and right sides when viewed from the center of the vehicle body, there is a side cover on the other side of the vehicle body where the exhaust silencer is not installed, symmetrical to the side cover on the side of the exhaust silencer. It is necessary to provide a side cover that does not have this function.
また、近年、この種の自動二輪車に対しても騒音低減の
要請が厳しくなっており、騒音対策の一つとして吸気騒
音を低減することが望まれている。Further, in recent years, demands for noise reduction have become stricter for this type of motorcycle as well, and it is desired to reduce intake noise as one of noise countermeasures.
本発明はこのような事情に鑑みなされたもので、排気消
音装置が配設されてない側のサイドカバーを有効に機能

消音装置を提供するものである。本発明に係る吸気消音
装置は、排気消音装置が配設されてない車体の他側に設
けたサイドカバーの内側にこのカバーを側壁として共鳴
箱を形成し、この共鳴箱を通路部材を介して吸気通路に
接続したものである。The present invention has been made in view of the above circumstances, and an object thereof is to provide an intake silencer for a motorcycle that allows the side cover on the side where the exhaust silencer is not installed to function effectively and further reduces intake noise. It is. In the intake silencer according to the present invention, a resonance box is formed inside a side cover provided on the other side of the vehicle body where the exhaust silencer is not provided, with this cover as a side wall, and the resonance box is connected to the side cover through a passage member. It is connected to the intake passage.
本発明においては、サイドカバーを利用して共鳴装置を
構成し、この共鳴装置によって吸気騒音を共鳴させる。In the present invention, a resonance device is configured using the side cover, and intake noise is caused to resonate by this resonance device.

である。そのため、サイドカバー７の内側には空間が形
成されている。6 is a resin side cover that covers the exhaust silencer 2;
Reference numeral 7 indicates a car in which the exhaust silencer 2 is not installed, and a side cover is provided symmetrically to the side cover 6 on the other side of the vehicle. Therefore, a space is formed inside the side cover 7.
１０は前記サイドカバー７の内側に配された樹脂製の箱
部材である。この箱部材１０は一方が開放された箱形状

はサイドカバー７を側壁として共鳴箱を形成している。Reference numeral 10 denotes a resin box member disposed inside the side cover 7. This box member 10 is formed in a box shape with one side open, and is attached so that the open part is closed with the side cover 7, thereby forming a space 11 defined between the side cover 7 and the side cover 7. . That is, the box member 10
forms a resonance box using the side cover 7 as a side wall.
箱部材１０の取付けについて詳述すると、サイドカバー

ある。To explain in detail how to attach the box member 10, a pair of walls 12 and 13 facing each other are erected in an annular shape on the inner surface of the side cover 7. On the other hand, a connection wall 14 that forms an annular groove between the edge 10a and the edge 10a of the box member 10 is integrally provided. Then, the connection wall 14 is connected to the wall 12.
, 13 to sandwich the wall 13, and connect the wall 13 to the connecting wall 14. Both members are joined to each other by intervening and sandwiching between the edges 10a. A sealing material 15 is loaded into the annular groove of the box member IO and keeps the space 1 airtight.

れている。Reference numeral 18 denotes a resin air cleaner disposed below the front of the seat 4 in the front-rear direction. This air cleaner 18 has a box-like shape, and has a suction duct l-19 for introducing outside air on the rear upper surface, and a discharge port 20 on the front surface. A joint 21 connects the air cleaner 18 and a carburetor (not shown), and is fitted onto the inner peripheral edge of the discharge port 20.

-20 forms an intake passage that supplies outside air to the carburetor. The inside of the air cleaner 18 is divided into two chambers on the upstream and downstream sides by a partition wall 18a.
An element 23 having a U-shape in side view is attached so as to cover the communication port 22 provided in a.

吸入ダク１−１９の側面に開口され径方向に突設された
接続部１９ａに接続されている。A flexible hose 24 serves as a passage member that connects the resonance box formed by the box member IO to the intake passage, and one end thereof is connected to the inner surface of the box member 10. The other end is connected to a connecting portion 19a that is opened on the side surface of the suction duct 1-19 and protrudes in the radial direction.

ことができる。Further, since the inside of the suction duct 19 and the inside of the box member 10 can be communicated with each other by the flexible hose 24, the space 11 of the side cover 7 can be made to function as a resonance chamber. Therefore, the side cover 7 can be used to configure a resonance device, and the engine intake noise propagated into the intake passage can be resonated and attenuated by this resonance device.
さらに、箱部材ｌＯは周壁が一種の補強リブとして機能
するため、サイドカバー７は従来のものに比較して剛性
が向上している。Furthermore, since the peripheral wall of the box member IO functions as a kind of reinforcing rib, the side cover 7 has improved rigidity compared to the conventional one.

部材間を固定的に接続してもよい。In the above embodiment, an example was explained in which the other end of the flexible hose 24 was connected to the intake duct 19, but the present invention is not limited to this, and the intake passage side is connected to the joint 1-21, etc. It can be changed as appropriate. Also,
The passage member is not limited to a flexible one, and both members may be connected in a fixed manner.

吸気騒音を共鳴させることができる。As explained above, according to the present invention, a resonance box is formed inside the side cover provided on the other side of the vehicle body where the exhaust silencer is not provided, with this cover as the side wall, and this resonance box is connected to the passage member. Since the side cover is connected to the intake passage through the side cover, a resonance device can be configured using the side cover, and the intake noise can be caused to resonate by this resonance device.
したがって、排気消音装置が配設されてない側のサイド
