Description
【考案の詳細な説明】 本考案は自動二輪車におけるエンジンに関する。[Detailed explanation of the idea] The present invention relates to an engine for a motorcycle.
従来重量の大きい発電機と始動装置をエンジンの外形々
状の中心線に対し１側に片寄せて設けている。Conventionally, a generator and a starter device, which are heavy in weight, are provided offset to one side with respect to the center line of the external shape of the engine.
このためエンジンの１側が重くなり、かＸるエンジンを
自動二輪車に塔載する場合自動二輪車の走行安定性を得
るため、自動二輪車の重心線を前后輪を結ぶ中心線上に
合わせる必要があると言う自動二輪車の性能その他から
求められる要請を充し難く、あえてこれを充たそうとす
ると、エンジンが車体の１側に片寄った状態に取付けな
げればならない等の不都合をともなう。For this reason, the first side of the engine becomes heavier, and when an engine is mounted on a motorcycle, it is necessary to align the center of gravity of the motorcycle with the center line connecting the front and rear wheels in order to obtain running stability of the motorcycle. It is difficult to meet the requirements of motorcycle performance and other factors, and if one were to try to meet these requirements, it would be accompanied by inconveniences such as the engine having to be mounted on one side of the vehicle body.
本考案はかＸる不都合のないエンジンを得ることをその
目的とするもので、前後輪を結ぶ自動二輪車の中心線に
直交してクランク軸４を配設する自動二輪車用エンジン

ータ８を連結したことを特徴とする。The object of the present invention is to obtain an engine free of such inconveniences, and in a motorcycle engine in which a crankshaft 4 is disposed perpendicular to the center line of the motorcycle connecting the front and rear wheels, the crankshaft Generator 3 at each end of 4
and an ignition coil interrupter 9, and a starting motor 8 is connected to the crankshaft 4 on the side of the ignition coil interrupter 9 via a starter 2.

０内に臨ませ、始動ギヤ５並びに点火コイル断続機９に
飛沫供給による潤滑を行わせるようにした。The illustrated starter device 2 includes a starter gear 5 connected to the crankshaft 4 via a one-way clutch 6, and a reduction gear 7 interlocked with the starter gear 5.
is supported on one side of the crankshaft 4, and a generator 3 is mounted supported on the other side of the crankshaft 4. Furthermore, an ignition coil interrupter 9 is mounted on the outside of the end of the crankshaft 4 where the starting gear 5 is attached. The ignition coil interrupter 9 should be one that can be used in an oil atmosphere, and the ignition coil interrupter 9 should be installed in the splash oil supply chamber 1.
0, and the starting gear 5 and ignition coil interrupter 9 are lubricated by droplet supply.
このように本考案によるときはクランク軸４の両端にそ

少なく十分な性能を維持できる等の効果を有する。In this way, according to the present invention, since the generator 3 and the ignition coil interrupter 9 are arranged at both ends of the crankshaft 4, the ignition coil interrupter 9, which is conventionally attached to the generator 3 side, is placed on one side of the crankshaft 40. Since it is installed without overhanging the crankshaft 4, the overhang of the crankshaft 4 can be reduced.
The left and right bank angle of the motorcycle can be maintained sufficiently, and since the starting motor 8 is connected to the crankshaft 4 on the side of the lightweight ignition coil interrupter 9 via a starter device, the weight balance of the crankshaft can be ensured. Since the ignition coil interrupter 9 is used in the oil atmosphere of the starter, it has the advantage of reducing friction and maintaining sufficient performance.
