AI Technical Summary

Technical Problem

Existing bicycles have complex chain drive structures, making it difficult to achieve flexible steering, such as turning left and right or swaying up and down.

Method used

It adopts a three-wheel-one-line design and a two-way rotating shaft structure, with the middle wheel always in contact with the ground to generate frictional power transmission, replacing the traditional chain drive.

Benefits of technology

The simplified structure enables flexible steering, including left and right turns and up and down swaying, and improves transmission efficiency.

Abstract

The invention discloses a three-wheel one-line and two-way rotating shaft chainless The first wheel and the third wheel are one-line. The device is worldwide pioneering and novel in shape. (see Figure 1). And 2, a bidirectional rotating shaft. One function is free to steer, and the other function is that the three wheels always touch the ground. (see Figure 2). And thirdly, no chain is used, the traditional chain transmission is broken, and the structure is simpler.

Description

[0001] Three-wheel single line, two-way rotating shaft, no chain bicycle.

[0002] One, three-wheel single line (see attached Figure 1 ), three wheels on a line, appearance original, simple and novel modeling.

[0003] Two, the design of double rotating shaft makes the middle wheel turn left and right with the front turning wheel, and also up and down, so that the middle wheel is always in contact with the ground under the action of the pedal force.

[0004] Three, no chain. Since the middle wheel is always in contact with the ground to generate friction power transmission, it replaces the traditional chain transmission, making the structure more simple. BRIEF DESCRIPTION OF DRAWINGS Figure 1 is a three-wheel single line, two-way rotating shaft, no chain bicycle; Figure 2 is a two-way rotating shaft part.

Claims

1. Three-wheel one-line, simple shape, unique structure.

2. Bidirectional rotating shaft, unique design.

3. No chain, cancel the traditional chain transmission, is a simpler structure.
