Description

【考案の詳細な説明】この考案は、スクーター等の自動二輪車の後輪
泥除けの改良に関する。[Detailed Description of the Invention] This invention relates to an improvement of a rear wheel mudguard of a motorcycle such as a scooter.

スクーター等の自動二輪車では、後輪の前側に
エンジンを配置する。そして、後輪は、上部を樋
形の泥除けで覆つている。泥除けの前下端が、エ
ンジンと後輪の間に入るので、エンジンはそれだ
け前側に配置されることになり、ホイールベース
が長くなる。又、泥除けの前下端とエンジンとは
近接して配置されるので、その間に手が入らず泥
が付着した場合掃除ができない不都合がある。 In motorcycles such as scooters, the engine is placed in front of the rear wheel. The upper part of the rear wheel is covered with a gutter-shaped mudguard. Since the lower front end of the mudguard is placed between the engine and the rear wheel, the engine is placed that much further to the front, resulting in a longer wheelbase. Further, since the lower front end of the mudguard and the engine are disposed close to each other, there is a problem in that it is impossible to reach between the mudguard and clean it if mud gets stuck.

この考案は、かかる点に鑑み改善したもので、

Embodiments of the present invention shown in the drawings will be described below. An engine 2 is arranged vertically below the seat 8 and in front of the rear wheels 1. In the engine 2, the cylinder 3 is tilted slightly backward, and the fan 4 at the end of the crankshaft and the cylinder 3
This is a forced air cooling type in which the cylinder 3 in the shroud 5 is cooled by being covered with a shroud 5 and the cylinder 3 inside the shroud 5 is cooled by blowing air from a fan 4 that rotates with the rotation of the engine 2. The rear wheel mudguard 6 is made of synthetic resin or the like and is molded into a gutter shape, and covers the upper part of the rear wheel 1. rear wheel mudguard 6
has a short front lower end and is connected to the rear upper end of the shroud 5. 7 is a frame cover.

しかして、後輪１の上部を覆つた後輪泥除け６

このため、シユラウド５と後輪１の間隔を近ずけ

前下端をシユラウド５に連結するので、後輪泥除
け６の前部の剛性を高めることもできる。 However, the rear wheel mudguard 6 that covers the upper part of the rear wheel 1
connects the front lower end to the rear upper end of the forced air cooling shroud 5 of the engine 2. Therefore, Shroud 5
will also serve as the front lower part of the rear wheel mudguard 6.
Therefore, the distance between the shroud 5 and the rear wheel 1 can be shortened, the engine 2 and the rear wheel 1 can be placed close to each other, and the wheelbase can be shortened and the vehicle can be made smaller and lighter. In addition, the rear surface of the shroud 5 can be accessed and cleaned if there is mud or the like. Furthermore, since the front lower end of the rear wheel mudguard 6 is connected to the shroud 5, the rigidity of the front portion of the rear wheel mudguard 6 can be increased.

以上説明したように、この考案は、後輪の前側

できる。 As explained above, this idea is based on a forced air-cooled engine placed vertically in front of the rear wheels. Since the front ends of the wheel mudguards are connected, the shroud can also serve as the front lower end of the rear wheel mudguard, and the engine can be moved closer to the rear wheels, making it smaller, lighter, and less expensive. Furthermore, if mud or the like adheres to the shroud, it can be cleaned by hand to prevent rust from occurring, and the rigidity of the front part of the rear wheel mudguard can also be increased.
