Description
Technical Field
The invention relates to the technical field of belt or chain transmission, in particular to a belt or chain transmission device and a motorcycle with the same.
Background
A belt drive is a mechanical drive that utilizes a flexible belt tensioned over a pulley for movement or power transmission. The belt drive generally consists of a driving wheel, a driven wheel and an endless belt tensioned over two wheels. The driving wheel is arranged on the driving output shaft, and the driven wheel is arranged on the power input shaft. The driving output shaft and the power input shaft are fixedly installed mechanical structures, so that the center distance between the driving wheel and the driven wheel is not variable. According to different transmission principles, there are friction belt transmission by the friction force between the belt and the belt wheel, and synchronous belt transmission by the meshing transmission of the belt and the teeth on the belt wheel. In any case, a certain tension is required, otherwise, the belt is easy to slip, the transmission efficiency is low, and even the transmission function is lost. This means that the belt needs to be assembled in place after being braced by a large external force, which is time-consuming and labor-consuming; in addition, the process can cause irreparable damage to the belt, and hidden mounting danger exists; meanwhile, the requirement on the material of the belt is increased, and the cost is also increased. At present, the tensioning of the belt is generally realized by adding a tensioning wheel. The addition of tension wheels not only increases the cost but also increases the bulk of the overall structure.
