Embodiment 1

[0049] Such as figure 1 and figure 2 As shown, an ultra-light bicycle equipped with the above-mentioned ultra-light bicycle acceleration device, wherein, the two ends of one side of the acceleration box shell 20 are provided with acceleration box fixing ears 21 up and down, and the acceleration box fixing ears 21 pass through the acceleration box. The fixed bolt 28 is connected to the inner side of the fork 7, the two ends of the main shaft 3 are hinged to the fork 7 through the bearing 4, the two ends of the main shaft 3 are also provided with pedals 6, and the hub 2 is connected through the spokes. For the wheel 1 , the upper end of the fork 7 is fixedly connected to a horizontally arranged fork assembly 8 , and the lower surface of the fork assembly 8 is provided with a fender 14 adapted to the wheel 1 . Such as image 3 and Figure 4 As shown, the ratchet mechanism includes a gear D18, a ratchet wheel 22, a pawl 23, a spring steel wire 24, a pawl seat 25, a pawl seat s...

Embodiment 2

[0058] On the basis of Example 1, such as Figure 12 to Figure 15 As shown, the top of the fork assembly 8 is connected to the handlebar 33 through the handlebar sleeve assembly 34, and the handlebar sleeve assembly 34 is connected to the seat sleeve assembly 36 through the horizontally arranged crossbeam 35. The seat 12 is arranged above the sleeve assembly 36 , the rear wheel brace 31 is connected to the bottom of the seat sleeve assembly 36 , and the small rear wheel 30 is hinged below the rear wheel brace 31 .

[0059] Compared with embodiment 1, embodiment 1 adopts single-wheel riding, and this embodiment adopts front and rear double-wheel riding, and increases handlebar 33, makes extra light bicycle safer and more stable, and adapts to a wider range.

[0060] Further, as Figure 14 or Figure 18 As shown, a seat post 11 is provided under the seat 12, and the seat post 11 is set in the seat sleeve assembly 36, and the seat sleeve assembly 36 is connected to the folding ...

Embodiment 3

[0064] On the basis of Example 2, such as Figure 8 to Figure 11 As shown, the number of the small rear wheels 30 is two, and they are all arranged on the outer sides of the rear wheel braces 31 .

[0065] Compared with Embodiment 2, this embodiment adopts one wheel on the front side and two wheels on the rear side, which is more stable, suitable for women, the elderly, preschool children, disabled people, etc., with higher safety and wider application range.

Abstract

The invention provides an ultra-light acceleration bicycle and an acceleration device thereof. The acceleration device comprises an acceleration box, the acceleration box comprises a main shaft, the main shaft is fixedly connected with a gear A, the gear A is meshed with a gear B, one side of the gear B is fixedly connected with a gear C, the gear B and the gear C are rotationally connected with an acceleration box shell through the two ends of a gear shaft, the gear C is meshed with a ratchet mechanism, the ratchet mechanism is in threaded connection with a hub, the hub is arranged outside the main shaft in a sleeving mode, and the main shaft horizontally penetrates through the acceleration box shell. The invention further provides an ultra-light bicycle provided with the bicycle acceleration device. The bicycle acceleration device and the ultra-light bicycle provided with the bicycle acceleration device are simple in structure, high in acceleration efficiency, ultra-light in weight, convenient to fold and carry and suitable for being used as substitute products of an existing bicycle acceleration device and an existing bicycle.

Description

technical field [0001] The invention relates to the technology in the field of bicycles, in particular to an ultra-light acceleration bicycle and an acceleration device thereof. Background technique [0002] Bicycles are a traditional industry with a history of more than 100 years. Due to environmental protection and traffic problems, bicycles have once again become a favorite transportation and fitness tool for residents of countries in the world, especially developed countries.
