[0004] But the installation position of the overrunning clutch in the above structure is unreasonable
The specific performance is: In order to reduce the harm of the dust brought by the belt to the overrunning clutch, it arranges the overrunning clutch and the drive clutch separately, but this arrangement of the overrunning clutch cannot make the overrunning clutch get sufficient lubrication, and it needs to be overrunning. Extremely inconvenient for clutch overinstallation and maintenance
Therefore, the installation position of the overrunning clutch in the above structure is unreasonable

Embodiment Construction
[0017] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0018] Such as figure 1 As shown, the power transmission device on the motorcycle includes a crankshaft 1, an intermediate shaft 2, a rear wheel shaft 3 arranged at the oil return hole 8 of the cylinder head of the motorcycle, and a driving clutch which is arranged on the first connecting end 11 of the crankshaft 1. 4, and the overrunning clutch 6 passing through the first connecting end 11 of the crankshaft 1. The second connecting end 12 of the crankshaft 1 is used for connecting with a power mechanism, where the power mechanism is a drive motor.
[0019] Specifically, the crankshaft 1 and the intermediate shaft 2 are arranged in parallel and are connected by a sprocket pair 5. When the crankshaft 1 rotates, the rotatio...

The invention provides a power transmission device on a motorcycle, belonging to the technical field of motorcycles. The device solves the problem that the installation positions of the existing overrun clutches are unreasonable. The device comprises a crank arranged at an oil return hole of the cylinder head of the motorcycle, an intermediate axle, a rear axle and a drive clutch penetrating through the first connection end of the crank; the crank and the intermediate axle are arranged in parallel and are connected with each other by a sprocket pair; the intermediate axle and the rear axle are arranged in parallel and are connected with each other by a transmission part; the second connection end of the crank is connected with a power mechanism; and an overrun clutch positioned at the inner side of the drive clutch also penetrates through the first connection end of the crank and pushes against the oil return hole. The device has the advantages of good lubrication effect, long service life and the like.
Description
technical field [0001] The invention belongs to the technical field of motorcycles, and relates to a transmission device, in particular to a power transmission device on a motorcycle. Background technique [0002] Motorcycle overrunning clutch, also known as electric starter clutch and one-way clutch, is an important part in the electric starter motorcycle engine. It is divided into a starting gear and a housing, and when the two are together, they are called an overrunning clutch assembly. Normally, its central inner ring is connected to the starter motor in the engine, and the housing is connected to the crankshaft of the engine. When the engine starts, the starter motor drives the overrunning clutch to rotate at high speed, generating a very large force, which drives the crankshaft to reciprocate , so that the engine piston works. Therefore, the overrunning clutch is an important part in the electric starter motorcycle. [0003] For example, a Chinese patent discloses ...
