Embodiment Construction

[0023]As shown in Figure 1, the input shaft 3 and the output shaft 4 are arranged in parallel, the distance between the two shafts remains unchanged, the sleeve gear 1 is placed on the input shaft 3, and the sleeve gear combination is composed of sleeve gears 1 with different diameters, and the sleeve gear with a larger diameter 1. A set of gears 1 with a smaller diameter can be used to manufacture more sets of gears 1. Each set of gears 1 has a ball bushing or a sliding bushing. 2. Each set of gears 1 can move laterally independently. There is a groove in the set gear 1 of the larger level to slide and connect with the key of the set gear 1 of the smaller level. The set gear 1 of the smaller level supports the set gear 1 of the larger level. When it is in neutral, as shown in Figure 1, the set gear 1 The fixed gear combination 5 is arranged on the output shaft 4, which is composed of the same number of gears as the set gear 1. It is arranged in a gradient order relative to the...

Abstract

The invention relates to a sleeve-gear transmission and folding bicycle. There is a group of sleeve gears matched with a group of fixed gears. A part is driven to move or rotate by rope or bar to extrude a sleeve gear matched with a fixed gear. When the part moves again matched sleeve gear retracts. Another sleeve gear extrudes and is matched with another fixed gear to change speed. Moving is carried out continuously reciprocating speed increasing and speed decreasing can be realized. Speed-variable process is lightness and smooth. The transmission is set on the oblique bar of bicycle and is connected with gear, ratchet wheel and two straight driving wheels. The diameter of wheel is small than 10cm and the speed exceeds in prior bicycle. A pin is drawn out the main cubage of folded bicycle is only 8X15X99 cm. The transmission also can be used in electrical bicycle, motorcycle and other mechanism.

Description

[0001] Technical field The present invention relates to a mechanical transmission device and a bicycle, especially a set of gear sets, the set of gears is composed of several sets of gears with different diameters, and the sets of gears with a diameter of one level are larger than the set of gears with a diameter of one level. , There are ball bushes or sliding bushes between these sets of gears, and the sets of gears can move laterally to mesh with corresponding fixed gears. Background technique [0002] At present, there are many types of known mechanical transmissions, mainly of the following types: [0003] 1. Ordinary gear transmissions transmit power through the meshing of gears. There are two or more gear combinations. When one gear combination is converted into another gear combination, the speed can be changed. [0004] 2. Chain-type tower-shaped transmission, which transmits power with a chain. There are two or more sprockets with different radii on the input shaft a...
