Description

Technical Field

[0001] This utility model relates to a motorcycle, and more particularly to a motorcycle having a transmission assembly. Background Technology

[0002] Existing motorcycles use chains, belts, or similar transmission components. These components sway up and down and side to side during power transmission. Excessive swaying can damage the transmission components themselves or the rocker arm. Current technology incorporates guide blocks to guide the chains and belts and prevent excessive swaying. However, the design of these guide blocks is flawed, making it difficult to provide effective guidance. Utility Model Content

[0003] This utility model provides a motorcycle to address the problems of the prior art, comprising a power system, a rocker arm, a rear wheel, a cover, and a guide. The power system includes a power output shaft, a power output wheel, and a transmission assembly. The power output wheel is sleeved on the power output shaft, and the transmission assembly is connected to the power output wheel. The power output shaft drives the power output wheel and the transmission assembly. The rocker arm is rotatably connected to the power system and is adapted to rotate about an axis along which the power output shaft extends. The transmission assembly connects the power output wheel and the rear wheel. The cover is connected to the rocker arm and covers the power output wheel. The guide is disposed on the cover and corresponds to the transmission assembly, and is adapted to guide the transmission assembly.

[0004] In one embodiment, the transmission assembly includes a groove, and the guide includes a guide portion that extends into at least a portion of the groove.

[0005] In one embodiment, the transmission assembly includes a groove, and the guide includes a guide portion located above at least a portion of the groove, the guide portion being adapted to extend into at least a portion of the groove when the transmission assembly is swayed upward.

[0006] In one embodiment, the guide includes a guide portion located between at least a portion of the transmission assembly and the rocker arm, the guide portion being adapted to guide the transmission assembly when the transmission assembly wobbles left and right.

[0007] In one embodiment, the guide extends toward the ground.

[0008] In one embodiment, the guide includes a limiting portion extending toward the rocker arm and located above the transmission assembly. When the transmission assembly swings upward, the limiting portion is adapted to limit the transmission assembly.

[0009] In one embodiment, the power output wheel is a pulley, and the transmission assembly is a belt.

[0010] In one embodiment, the power output wheel is a sprocket and the transmission assembly is a chain.

[0011] In one embodiment, the cover includes an inner cover facing the rocker arm, and the guide is locked onto the inner cover.

[0012] In one embodiment, the motorcycle also includes a frame, to which the power system is locked.

[0013] In the motorcycle using this embodiment of the invention, the guide is located on the cover and is therefore close to the power output shaft. Since the power output shaft receives a large amount of power, it is the primary point where transmission components such as chains and belts swing. Therefore, guiding the transmission components at this location to limit their swing amplitude achieves a better restraint effect. It also effectively prevents damage to the transmission components themselves or the rocker arm. Attached Figure Description
