Novel connecting structure for five-way joint center shaft bevel gear and bicycle rim

Abstract

The invention discloses a novel connecting structure for a five-way joint center shaft bevel gear and a bicycle rim. The novel connecting structure for the five-way joint center shaft bevel gear and the bicycle rim comprises a bicycle five-way joint, a five-way joint center shaft, a clutch, the five-way joint center shaft bevel gear, a first transmission bevel gear, a second transmission bevel gear, an output bevel gear and the bicycle rim. The five-way joint center shaft is rotationally connected with the bicycle five-way joint. The five-way joint center shaft bevel gear can rotate relative to the five-way joint center shaft. The clutch is arranged between the five-way joint center shaft and the five-way joint center shaft bevel gear. The five-way joint center shaft bevel gear is meshed with the first transmission bevel gear. The second transmission bevel gear is meshed with the output bevel gear. The first transmission bevel gear and the second transmission bevel gear synchronously rotate. The output bevel gear is fixedly connected with the bicycle rim. The novel connecting structure for the five-way joint center shaft bevel gear and the bicycle rim is compact in structure, does not change the existing structure of a rear wheel of a bicycle and does not influence the attractiveness of an original product, and meanwhile because the clutch of a bicycle bevel gear structure is arranged on the five-way joint center shaft, the transmission space of the back wheel is greatly reduced.

Description

technical field [0001] The invention relates to the field of bicycle accessories, in particular to a connection structure between a novel bottom bracket bevel gear and a bicycle rim. Background technique [0002] The installation structure of the traditional bicycle bottom bracket bevel gear is: the bevel gear on the bottom bracket is fixed by key pins without clutch performance. The loose tooth structure on the bottom bracket has no clutch, so the original model needs to be changed to increase the clutch, which increases the opening size of the rear wheel and increases the limited space of the original model. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a new connection structure between the bottom bracket bevel gear and the bicycle rim with its own clutch function and saving transmission space. [0004] Technical solution: In order to achieve the above object, the conn...
