Problems solved by technology

[0003] 1. The overall structure needs to be improved. For example, it is difficult to process the inner teeth of the reverse inner ratchet 12; the combination of the planetary gear frame 2 and the mandrel 18 requires matching storage; there are redundant parts and inconvenient assembly, etc.
[0004] 2. When the ratchet overrunning clutch is overrunning and sliding, the ratchet will make noise when the pawl hits the ratchet, which also shows that the ratchet overrunning clutch has excess energy consumption when overrunning and sliding

Embodiment Construction

[0022] The structure and operation process of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Accompanying drawing is an embodiment that the present invention is used as bicycle rear axle, and this embodiment comprises left end cap 1, planetary wheel frame 2, mandrel 3, spring 5, positioning key 6, reversing bar 7, sun wheel 8, planetary wheel 9 , Reverse torsion overrunning clutch driven casing 10, transmission shaft 11, sprocket 12, right end cover 13, pawl 14, reverse torsion overrunning clutch torsion member 15, cage 16, internal gear 17 and housing 18 . The planetary gear 9 meshes with the sun gear 8 . The outer edge of the right end cover 13 has threads to be screwed with the housing 18, the inner edge has a ball raceway, and the inner ratchet is engaged with the ratchet 14. There is a ratchet groove on the transmission shaft 11, and the ratchet 14 is positioned in the ratchet groo...

Abstract

The invention relates to a double-direction double-speed bicycle with a built-in booster. When the bicycle is pedaled forward, it runs similar to general bicycle. When the bicycle is pedaled backward, the built-in planetary gear is driven by a reverse-engaged super-clutch to make the bicycle get a boosted drive force and run forward still. The bicycle needs no other speed-change and shifting mechanism, which can quickly and repeatedly change speed. Advantages: simple design, reliable drive and convenient using.

Description

Technical field [0001] The invention relates to a transmission for vehicles, in particular to a rickshaw variable speed drive shaft used by vehicles and appliances driven by human power. Background technique [0002] Generally, human-driven vehicles, such as bicycles, tricycles, wheelchairs, etc., are very convenient to use under normal circumstances, but when going uphill, when facing the wind, when carrying a load, and when the road is muddy, you will feel that the driving force is insufficient. This is because ordinary non-variable vehicles are mostly driven by acceleration transmission. To increase the driving force, you must try to reduce the acceleration transmission ratio. For this reason, people have designed multiple bicycle speed changers, and a common one is that multiple rows of sprockets with different numbers of teeth are respectively installed at the center shaft and the rear axle of the bicycle. Manipulate the front and rear derailleurs respectively, and put...
