As a specific aspect of the present invention, it may be preferable that: the well axis body includes annular bellying and oil blanket portion, the oil outlet is located annular bellying.

Through the arrangement, the annular bulge part plays a role in limiting the middle shaft body, so that the situation that the position of the output shaft of the motorcycle is easy to deviate after long-term use is avoided, and the oil seal part can prevent lubricating oil from leaking; the oil outlet is located the annular bulge, makes the lubricating oil that the oil outlet flows can lubricate the annular bulge, reduces frictional force.

As a specific aspect of the present invention, it may be preferable that: and the joint of the middle shaft body and the lower shaft body is in transition through an arc chamfer.

Through the arrangement, the arc chamfer increases the contact area of the middle shaft body and the lower shaft body, so that the structural strength is increased, and the fastness of the output shaft of the motorcycle is effectively improved.

As a specific aspect of the present invention, it may be preferable that: the axis body still includes the axle tail, the center of axle tail all is equipped with axial screw.

Through the arrangement, the axial screw hole plays a limiting role after the installation of the motorcycle output shaft is completed, and the stability of the motorcycle output shaft is further improved.

The utility model discloses technical effect mainly embodies in following aspect: the weight of the upper shaft body is adjusted by increasing or reducing the number of the balancing weights, so that the effect of adjusting the weight distribution of the output shaft is achieved, the stability of the output shaft when the output shaft transmits the shaft power is improved, and the service life of the output shaft is prolonged; the second inner chamber can store some lubricating oil, and the lubricating oil in the second inner chamber can be followed the oil outlet and flowed out, thereby plays the lubricated effect that reduces friction of well axis body, runs out the back when the lubricating oil in the second inner chamber, and people can take out the balancing weight, then pours into lubricating oil into to the second inner chamber through following first inner chamber into, pours back the balancing weight again and plugs up lubricating oil into the back that finishes, and convenient operation and lubricated effect are relatively good.
