Abstract

The invention discloses a centrifugal clutch assembly integrated structure and an automatic speed change hub with a large gear ratio, and relates to the field of speed change devices. According to the technical scheme, the clutch is characterized by comprising a first clutch inner ring part, a first clutch driving piece and a first buffer frame; and a second clutch inner ring portion, a second clutch driving member and a second buffer rack. The first clutch inner ring part and the second clutch inner ring part are fixedly connected or integrally formed to form an integrated inner ring. According to the invention, the number of parts and assembly procedures can be reduced, the production cost and the detection cost can be reduced, the reliability and the stability can be improved, meanwhile, the structure can be simplified, the size can be optimized, automatic switching of three gears can be realized by utilizing the output speed, and the gear ratio can be improved, so that the riding experience can be further optimized.

Description

technical field [0001] The invention relates to the field of transmission devices, more specifically, it relates to an integrated structure of a centrifugal clutch assembly and an automatic transmission hub with a large transmission ratio. Background technique [0002] The general internal speed change mechanism uses centrifugal force to realize automatic speed change. When a certain cadence speed is reached, the centrifugal block is thrown away to realize automatic upshifting. When the cadence speed drops below the speed change point, the centrifugal block will shrink to realize automatic downshifting. For example, it is shown in the Chinese patent whose authorized announcement number is CN208882034U. [0003] However, for the vehicle using the above-mentioned speed change mechanism, when the vehicle is running at high speed (greater than the speed change point), if the rider does not want to step on it, or does not need to step on the downhill, the speed change mechanism w...
