【考案の詳細な説明】
この考案は、オートバイのエンジンカバー防振装置に関
する。[Detailed Description of the Invention] This invention relates to a motorcycle engine cover vibration isolation device.
オートバイのエンジンは、変速歯車が一体的に組込ｌれ
ており、主ケースの両側を、カバーで覆っている。A motorcycle engine has a transmission gear integrally incorporated therein, and both sides of the main case are covered with covers.
カバーは、主ケースにビス止めされているが、後輪を駆
動するチエン側は、チェノの通る部分を設けるため、カ
バーがチェノケースと連なるように後方に突出している
。The cover is screwed to the main case, but on the chain side that drives the rear wheels, the cover protrudes rearward so as to be continuous with the chain case, in order to provide a section for the chain wheel to pass through.
この突出部は、主ケースにビス止めできないので、エン
ジン振動に共振して大きい振動が発生し、振動騒音を発
生する。Since this protrusion cannot be screwed to the main case, it resonates with the engine vibration, generating large vibrations and generating vibration noise.
この考案は、かかる点に鑑み改善したもので、以下図面
に示す本考案の実施例について説明する。This invention has been improved in view of these points, and an embodiment of the invention shown in the drawings will be described below.
カバー１は、エンジン２の主ケース３にビス４によって
続着される。The cover 1 is successively attached to the main case 3 of the engine 2 with screws 4.
エンジン２の駆動スプロケット５と後輪スプロケット６
はチェノ７で連結されている。Engine 2 drive sprocket 5 and rear wheel sprocket 6
are connected by Cheno 7.
このため、チエン７側のカバー１は、後端がチェノ７が
通るように開放してあり、又、チェノケース８と連なる
ように後方に大きく伸びている。Therefore, the rear end of the cover 1 on the side of the chain 7 is open so that the chain 7 can pass therethrough, and it also extends significantly rearward so as to be continuous with the chain case 8.
この後方突出部９の内側に突起１０を設けて、弾性片１
１を取着する。A protrusion 10 is provided inside this rear protrusion 9, and the elastic piece 1
Install 1.
弾性片１１の他端は、車体１２に押圧させ、カバー１の
後方突出部９と二゛車体１２の間に弾性片１１を弾挿さ
せる。The other end of the elastic piece 11 is pressed against the vehicle body 12, and the elastic piece 11 is elastically inserted between the rear protrusion 9 of the cover 1 and the two vehicle bodies 12.
伺、弾性片１１は、車体１２側に止めてもよく、又、ビ
ス等を用いて固定してもよい。The elastic piece 11 may be fixed to the vehicle body 12 side, or may be fixed using screws or the like.
作用について説明する。The effect will be explained.
カバー１の後方突出部９は、ビス４によって止めた個所
がなく、エンジン２の回転振動で主ケース３が振動する
と、・この影響を受けて、共振し、大きく振動しようと
するが、弾性片１１によって支えられているので、大き
い共振が防がれ、振動音の発生が少なくなる。The rear protrusion 9 of the cover 1 is not fixed by the screws 4, and when the main case 3 vibrates due to the rotational vibration of the engine 2, it will resonate and vibrate greatly under this influence, but the elastic piece 11 prevents large resonance and reduces the generation of vibration noise.
又、主ケース３と車体１２とは、振動による動きがある
が、弾性片１１は、伸縮して吸収できる。Furthermore, although the main case 3 and the vehicle body 12 move due to vibration, the elastic piece 11 can expand and contract to absorb the movement.
以上説明したように、この考案は、エンジンのチェノ側
カバーの後方突出部の内側と車体との間に弾性片を弾挿
したので、カバーを弾性片で支えることができ、エンジ
ンの振動に共振して、カバーが大きく振動して振動騒音
を発生するのを押えることができる。As explained above, in this invention, an elastic piece is elastically inserted between the inside of the rear protruding part of the engine engine side cover and the vehicle body, so the cover can be supported by the elastic piece, and it resonates with engine vibrations. This prevents the cover from vibrating too much and generating vibration noise.
又、弾性片であるので、カバーと車体との位置変化も吸
収でき、安価に製作できてコストアップも少ない。In addition, since it is an elastic piece, it can absorb changes in the position of the cover and the vehicle body, and can be manufactured at low cost with little increase in cost.
図は本考案の一実施例を示し、第１図は側面図、第２図
は第１図Ａ矢視拡太図、第３図は第２図Ｂ−Ｂ矢視拡犬
断面図である。The figures show one embodiment of the present invention, in which Fig. 1 is a side view, Fig. 2 is an enlarged view taken along arrow A in Fig. 1, and Fig. 3 is an enlarged sectional view taken along arrow B-B in Fig. 2. .
