Abstract

A casing rotary automatic transmission, which consists of a cylindrical casing, an input end cover, and an output end cover that are fixedly connected to form a casing. The input gear is fixed at the end of the input gear, and it is rotatably set on the wheel shaft with a ratchet fixed and plate-shaped planetary gear brackets on both sides of the ratchet. Between the two outer ends of the two planetary gear brackets, a planetary gear is movably connected. The two ends of the shaft are fixedly connected with a planetary gear and a planetary pinion, and the middle part is fixedly connected with an eccentric gear. The planetary gear meshes with the input gear, and the planetary pinion meshes with the output gear. The spring ring and the output end cover are fixedly connected with the output gear, and are rotatably sleeved on the other end of the wheel shaft, and the two ends of the wheel shaft are fixed on the rear wheel frame. The invention has the advantages that the casing rotates to become a part of the wheel, is convenient to use, and is suitable for 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...
