Abstract

The invention provides an encloser rotation automatic gear shift. A cylindrical encloser, an input end cover, and an output end cover are permanently connected to constitute an encloser. The structure of the invention is as follows: the input end cover is enclosed on a hollow input shaft in a rotatable way; the end of the hollow input shaft in the encloser is fixed with an input gear, and is enclosed on a wheel axle fixed with a ratchet; plate-shaped planetary gear brackets are enclosed on both sides of the ratchet; a planetary gear shaft is flexibly arranged between the two outer ends of the two planetary gear brackets; both ends of the shaft are permanently connected with a large planetary gear and a small planetary gear; an eccentric wheel is permanently connected in the middle; the large planetary wheel is joggled with the input gear; the small planetary wheel is joggled with an output gear; the inner side of the eccentric wheel is provided with an elliptic ring spring; the output end cover is permanently connected with the output gear, and is rotatablely sheathed on the other end of the wheel axle; both ends of the wheel axle are fixed on a rear wheel carriage. The invention has the advantages that as one part of the wheel, the encloser rotation automatic gear shift is usable, and is applicable to vehicles such as bicycles and motorcycles.

Description

technical field [0001] The invention relates to the technical field of vehicle speed changers, and is suitable for automatic speed change of bicycles, motorcycles and the like which are driven by chain flywheels. technical background [0002] At present, known transmissions for bicycles and motorcycles are usually manual transmissions, which are inconvenient to use although their manufacturing costs are low. People wish to have a kind of simple in structure, low in manufacturing cost, easy to use automatic transmission, replace existing manual transmission. Contents of the invention [0003] The object of the present invention is to provide a casing rotary automatic transmission with simple structure, reliable operation, low manufacturing cost and convenient use. [0004] In order to achieve the above object, the present invention takes the following technical solutions: [0005] A casing rotary automatic transmission, which includes a cylindrical casing, an input end co...
