Description

Bicycle dish, hub and transmission structure

The present invention relates to a bicycle component, and more particularly to a disc and a transmission structure capable of greatly reducing the folded volume of a single-arm bicycle.

According to the conventional one-arm bicycle rear wheel, there is no design of the shifting transmission sleeve and the disc on the same side, and the rear wheel generally adopts the traditional rim brake clamp, due to the clamp of the wheel clamp Both the arm and the brake block are arranged on the left and right sides of the rear wheel, so that the volume of the single-arm bicycle is folded due to the barrier of the clamp and the brake block, so that the separation distance between the front and rear wheels cannot be further reduced after the folding of the vehicle body, and other conventionally known Although the one-arm bicycle adopts the disc brake device in the rear wheel, it cannot set the shift transmission sleeve, and the rear wheel has no shifting function.

Since then, the creators of this case have continued to develop research and improvement after successfully developing single-arm bicycles many years ago. Now they have finally broken through the use of space and innovative structural design, and successfully developed a new single-arm bicycle disc drum and transmission. The structure enables the single-arm bicycle to be equipped with a multi-stage shifting sleeve on the rear wheel, and a disc brake device is arranged on the same side, thereby further improving the riding and braking function of the single-arm bicycle and reducing the volume after folding.

The main purpose of this creation is to provide a bicycle disc drum and transmission structure, which is a disc honing drum and transmission structure device for a single-arm bicycle rear wheel, which can make the single-arm bicycle rear wheel have multiple segments at the same time. The shifting and disc mechanism further enhances the riding and braking functions and greatly reduces the volume of the vehicle after folding.

Please refer to the first to third figures, the bicycle disc and the transmission structure, which mainly comprises: a shaft 01, the shaft 01 is provided with a plurality of Palin 011; a hub 02, the hub 02 The hollow type is sleeved on the left side of the shaft 01, and is supported by the Palin 011 of the shaft 01 and the shaft 01, so that the hub 02 is rotated, and the inside of the opening of the right side of the hub 02 is provided. a ratchet ring 021, a plurality of ratchet teeth 022 are arranged on the inner circumference of the ratchet ring 021, and a disc tray fixing seat 023 is arranged on the outer edge of the opening of the right side of the hub 02; a disc tray 03, the disc tray 03 The sleeve is mounted on the disc holder fixing base 023, and the disc tray 03 is screwed and fixed by using a screw 031; a sleeve 04 is a hollow body which is pierced at both ends and is sleeved on the shaft center 01 On the right side, the sleeve 04 is internally provided with a Palin 041 connected to the shaft 01, so that the sleeve 04 can be rotated, and the outer edge of the sleeve 04 is axially divided with a plurality of concave and convex teeth 044, a toothed disc The 047 is sleeved on the sleeve 04 and is engaged with the latch 044. The left side of the sleeve 04 is provided with a pawl ring 042, and the right end opening is provided with a right end cover 048. The pawl ring 042 is set. An opening corresponding to the right side of the hub 02, the pawl ring 042 is provided with at least one movable pawl 045 and a pawl chamber 043 capable of accommodating the pawl 045, the pawl 045 is a 591 coil of a claw spring Provided on the pawl ring 042, the elastic force of the claw spring 046 causes the pawl 045 to engage with the ratchet 022 of the ring gear 021, and the pawl 045 can be driven to rotate the hub 02 via the rotating sleeve 04 to enable the hub 02 to rotate in one direction. Thereby, the single-arm bicycle rear wheel can be equipped with a multi-speed shifting and disc-disc mechanism at the same time, further improving the riding and braking functions and greatly reducing the folded volume.

In summary, this creation has been made into actual samples as the patent specification and schema content, and has been proved by many tests to achieve its intended purpose and efficacy. It has practical value and potential for market development. The provisions of the law file a patent application with the bureau.

However, the above is only the preferred embodiment of the present invention. When it is not possible to limit the scope of the implementation of this creation, the equivalent changes and modifications made by the scope of the patent application of this creation should still be covered by this creation patent.
