Embodiment Construction

[0023] First please refer to figure 1 Referring to Fig. 5, the driving seat structure of a bicycle hub provided by the present invention is mainly arranged on one side of the hub 40, which includes: a driving seat 10, and the driving seat 10 A plug-in 20.

[0024] The drive seat 10 is an aluminum alloy in a stepped ring, which has a transmission part 11 with a smaller outer diameter. The outer diameter edge ring of the transmission part 11 is provided with six transmission bars 12 and three intermittent protrusions. Strips 13 are respectively axially extended by the drive seat 10 to a preset length, wherein each of the intermittent convex strips 13 is in the shape of a discontinuous flange with two grooves 131; the intermittent convex strips The two side edges of the groove 131 formed by 13 are dovetail-shaped recesses.

[0025] The insert 20 is a steel material that is embedded and attached to each of the intermittent protrusions 13, and the intermittent protrusions 13 and...

Abstract

The present invention provides a driving seat structure of a colored hub of a bicycle, which is arranged at one side of the hub and comprises the following components: a driving seat which is a step-shaped ring body and is provided with a driving part that has a smaller outer diameter, the rim ring of the outer diameter is provided with a plurality of transmission strips and at least one intermittent projected strips which respectively extend for a preset length from the driving seat, wherein the intermittent projected strips have an intermittent flange which is provided with a groove; the driving seat structure is also provided with a plug-in connector which is inserted and jointed on the intermittent projected strip and commonly form a strengthening rib with a preset width. The strengthening rib is formed by the arrangement of the connector with a harder material with the components to disperse the high-capacity torque-force generated from the large-area contact when the hub is inserted and rotated. The damage between the components can be effectively reduced and the service lifetime can be prolonged.

Description

technical field [0001] The invention relates to a bicycle speed change gear drive system, in particular to the structure used in the joint of the sprocket drive seat and the sprocket of the transmission wheel. Background technique [0002] The transmission system of a bicycle mainly includes components such as a flywheel, a large chainring, a transmission, a chain, a shift lever, and a cable; the transmission guides and adjusts the chain by using the combination of the large chainring and the number of teeth before and after the flywheel. Adjust the position on different gears, and switch to the appropriate speed ratio and efficiency to match the road conditions and achieve the purpose of comfortable riding. [0003] The variable-speed bicycle using the sprocket transmission device has a structure with multiple sprockets connected to the rear wheel for many years. At present, it is trending to use a pinch shaft drive seat at the hub of the rear wheel to accommodate multiple ...
