Frame of motorcycle

Abstract

The invention provides a frame of a motorcycle, and belongs to the technical field of motorcycles. The frame solves the problem that an existing motorcycle frame is not high in shaft transmission stability. According to the frame of the motorcycle, the motorcycle comprises a front transmission case, a transmission shaft, a rear transmission case and the frame, the front transmission case and the rear transmission case are connected through the transmission shaft, an installation shell is arranged outside the transmission shaft, a first hinge part is formed on the rear transmission case in a protruding manner, and a second hinge part is formed at one end of the installation shell in a protruding manner. The frame further comprises a connecting rod mechanism. The connecting rod mechanism comprises a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged to the first hinge part, the other end of the first connecting rod is hinged to the frame, one end of the second connecting rod is hinged to the second hinge part, and the other end of the second connecting rod is hinged to the frame. According to the frame of the motorcycle, the stability of a whole motorcycle body can be improved.

Description

technical field [0001] The invention belongs to the technical field of motorcycles and relates to a motorcycle frame. Background technique [0002] With the continuous improvement of people's quality of life, the performance of motorcycles is also the primary object of observation. [0003] The existing motorcycles or electric vehicles basically use chain transmission, but during the operation of the chain transmission, the chain is prone to be elongated and deformed after a period of use, and the chain is used for a long time. Not only is it easy to rust and has a short lifespan, but it also requires frequent oiling and maintenance of the chain. The efficiency of the chain itself is low, resulting in the transmission efficiency of the entire transmission device. [0004] In view of the above existing problems, people gradually adopt shaft drive instead of chain drive. The drive shaft is directly connected with the frame. Therefore, the gravity of the drive shaft on the fra...

AI Technical Summary

Problems solved by technology

[0003] The existing motorcycles or electric vehicles basically use chain transmission, but during the operation of the chain transmission, the chain is prone to be elongated and deformed after a period of use, and the chain is used for a long time. Not only is it easy to rust and has a short lifespan, but it also needs frequent oiling and maintenance of the chain. The efficiency of the chain rotation itself is low, resulting in the transmission efficiency of the entire transmission device.

[0004] In view of the above existing problems, people gradually adopt shaft drive instead of chain drive. The drive shaft is directly connected with the frame. Therefore, the gravity of the drive shaft on the frame is relatively large. Therefore, during the operation of the vehicle, When the car body vibrates or collides, it will affect the position of the transmission shaft, which in turn affects the stability of the entire shaft transmission and reduces the stability of the entire frame
