Problems solved by technology

[0006] It is very difficult to remove the ring gear because it fits against the opening 23 formed in the end of the hub.
Once the tooth collapse occurs, even if the old gear ring is removed, the opening wall of the hub will be damaged and deformed by external force, which is not conducive to the maintenance and fixing of the new gear ring
[0007] Secondly, the design of the ring part and the sprocket seat is integrated, so that the ratchet can only be applied to the gear ring with the same number of teeth, and the maintenance work is limited to the replacement of the same components
[0008] Whether it is China Taiwan No. M314697 or No. I423899 patent case, it is not conducive to the maintenance operation

Embodiment Construction

[0028] see Figure 1 ~ Figure 3 , to clarify the specific construction of the first embodiment of the actuator 10 . The actuator 10 is an independent combination consisting of a ring piece 12 , an outer ring 20 , an inner ring 30 and a one-way transmission structure 40 installed between the inner and outer rings 20 , 30 .

[0029] In the figure, the outer ring 20 described has an outer ring surface 22 that is not a true circle. The outer ring surface 22 includes six flat surfaces 24 and six convex curved surfaces 26. Each convex curved surface 26 is adjacent to the flat surface 24 on both sides, so that the outer annular surface 22 Roughly hexagonal.

[0030] The outer ring 20 also has a plurality of teeth 21 and two receiving grooves 28 . The plurality of teeth 21 protrude continuously at the center of the inner surface of the outer ring 20 , and each tooth 21 is preferably a ratchet. The two receiving grooves 28 sink into the end of the outer ring 20 and are located on bo...

Abstract

The invention provides a replaceable actuator and a wheel drive assembly using the same; the replaceable actuator comprises an inner ring, a set of outer ring sleeving on the inner ring; and a one-way transmission structure installed between the inner ring and the outer ring and deciding one-way synchronized actuation and reversed idling non-actuation. the actuator is installed between a hub and a chain wheel seat to form a new wheel drive assembly. wheel drive assembly maintenance work can be completed only by replacing the actuator, which is simple, easy and rapid to operate.

Description

technical field [0001] The invention relates to the transmission technology of a bicycle, in particular to a replaceable actuator and a wheel transmission assembly using the actuator. Background technique [0002] The known bicycle has a frame, and the frame is mostly connected with two wheels, a large chainring and a wheel drive assembly, and the large chainring can be driven to rotate by two staggered cranks, and a chain is used to drive around the large chainring and the wheel Assembly. The wheel transmission assembly includes a wheel shaft installed on the frame, a hub connected to the wheel and a sprocket set. The wheel shaft passes through the hub and the sprocket set. The sprocket set receives the kinetic energy of the chain and transmits it to the hub to drive the wheel. Roll on the ground. [0003] The early sprocket set has a sprocket seat, and the sprocket seat is equipped with several sprockets. These sprockets have different numbers of teeth and can be driven ...
