この発明は、遠心クラッチ付きオートバイの安全装置に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for a motorcycle with a centrifugal clutch.
小型オートバイは、エンジンと後輪に連結された波動歯
車との間に、エンジン回転が発進速度に達すると自動的
に接続する遠心クラッチが装着されたものがある。Some small motorcycles are equipped with a centrifugal clutch that is automatically connected between the engine and a wave gear connected to the rear wheel when the engine reaches a starting speed.
この装置は、エンジンの回転をコントロールするアクセ
ルグリップだけで運転操作がてき、運転技術の低い人に
も容易に操作できて便利である。しかし、エンジン始動
時にアクセルを開いてあると、始動と共に急にエンジン
回転が上昇し、オートバイが急に走り出す危険がある。
この発明は、かかる危険がないようにすると共に、操作

の実施例について説明する。This device can be operated simply by using the accelerator grip, which controls the rotation of the engine, making it convenient and easy to operate even for people with low driving skills. However, if the accelerator is opened when the engine is started, the engine speed will suddenly increase as soon as the engine starts, and there is a danger that the motorcycle will start running suddenly.
The present invention provides a safety device that eliminates such risks and is easy to operate.Examples of the present invention shown in the drawings will be described below.

て説明する。A clutch hub 3 is rotatably mounted on a drive shaft 2 of an engine 1. The clutch hub 3 is provided with a connecting centrifugal clutch 4 that is connected during idling rotation, and a starting centrifugal clutch 5 that is connected when the starting speed is reached. Note that both clutches may be of a type in which a shoe of a centrifugal weight is expanded by centrifugal force against a spring to connect them. and connecting centrifugal clutch 4
A first clutch housing 6 to which the starting centrifugal clutch 5 is extended and connected is fixed to the drive shaft 2, and a wave gear 8 is fixed to a second clutch housing 7 to which the starting centrifugal clutch 5 is spread and connected. The wave gear 8 includes a reduction gear 9, a sprocket 10, and a chain 1.
It is connected to the rear wheel via 1. A manual disc 12 is slidably provided on one side of the clutch hub 3 and brought close to the inner surface of the first clutch housing 6. A brake wheel 13 threadedly engaged with the drive shaft 2 is provided, and a clutch hub 3
The inner end of the brake wheel 13 and the manual disc 12 are brought into contact with each other through a rod 14 passed through the brake wheel 13. A return spring 15 is installed between the brake wheel 13 and the drive shaft 2. A brake piece 16 is provided on the outside of the brake wheel 13, and the brake piece 16 is connected to a manual lever 18 via a Bowden wire 17. The manual lever 18 may be a car brake lever. The effect will be explained.
エンジン１をスタータで始動させる。Start engine 1 with the starter.
このとき駆動軸２及び第１クラッチハウジング６が一体

安全である。At this time, the drive shaft 2 and the first clutch housing 6 rotate together. However, since the clutch hub 3 is disconnected, the engine 1 can be warmed up by increasing the rotation appropriately. And when you're ready to drive,
When the manual lever 18 is pulled, a brake is applied to the brake wheel 13 that rotates together through the drive shaft 2 and the return screw 15, and the brake wheel 13 moves to the right due to the screw engagement, causing the rod 14 to move. The manual disc 12 is pressed against the first clutch housing 6 through the clutch. As a result, the clutch hub 3 starts rotating. When the clutch hub 3 rotates, the centrifugal clutch 4 and the first clutch housing 6 are immediately connected.
Thereafter, even if the manual lever 18 is released and the brake wheel 13 is released, the clutch hub 3 continues to rotate by the coupling clutch 4. Then, when the rotation of the engine 1 is increased to reach a starting speed, the starting centrifugal clutch 5 is connected to the second clutch housing 7, the driven gear 8 is rotated, and the car starts running.
Once the engine 1 is stopped, the manual disc 12 and
The connecting centrifugal clutch 4 is disengaged. In this way, the car does not start running simply by starting the engine 1, and when the driver wishes to run the car, the user operates the manual lever 18 to be able to start walking. Also, manual lever 18
, by simply lightly braking the brake wheel 13, the manual disc 1
The force for pressing 2 is performed by the axial component force of the screw engagement, so the operation is light. Note that the manual lever 18 may also be used as a brake lever, and in this case, the car is once in a braked state, which further increases safety. As explained above,
In this invention, a connecting centrifugal clutch that is connected at idling rotation and a starting centrifugal clutch that is connected at starting speed are provided on a clutch hub rotatably mounted on three drive shafts of an engine, and a first clutch housing for the connecting centrifugal clutch is provided. A driven gear is provided in a second clutch housing that is fixed to the drive shaft and is connected to the starting centrifugal clutch, and a manual disc that is slidably attached to the clutch hub is attached to the inner surface of the first clutch housing. The inner end side of the brake wheels arranged to face each other and threadedly engaged with the drive shaft presses the manual disc against the inner surface of the first clutch housing when the other brake wheel moves in the direction of the manual disc. A return spring was installed between the brake wheel and the drive shaft, and the brake piece of the brake wheel was connected to the manual lever, so the manual lever was operated to move the manual disc to the first position.
It is ready for driving only after it is connected to the clutch housing, the clutch hub is rotated, and the connected centrifugal clutch is connected. In this way, the car will not start running against your will immediately after starting the engine, making it safer. In addition, the manual lever only brakes the brake wheel, and the manual disc is pressed by the axial force of the screw engagement, so it requires only a light operation. Once the engine is stopped, the connected centrifugal clutch is disengaged, and even when the engine is started next time, a manual lever must be operated to start the vehicle, making it safe to start at any time.
