Abstract

The invention discloses a bicycle with a miniature box transmission on a middle axle. The bicycle comprises a frame device, a transmission device, a moving device and a safety device and is characterized in that: the middle axle of the frame device is provided with the miniature box transmission consisting of a box speed transformation device and a shifting device; the middle axle and an auxiliary axle are arranged in a box; a clutch sleeve and a driving gear are fixedly arranged on the middle axle; the right outer end of the middle axle is in movable fit with a middle axle driven gear and a chain wheel; a clutch sleeve and a driven gear are fixedly arranged on the auxiliary axle; and an auxiliary axle driving gear is fixedly arranged at the right outer end of the auxiliary axle and engaged with the middle axle driven gear. The bicycle has a small and compact structure, large transmission ratio range, high climbing capability, high level road speed, low production cost and high popularization value, is convenient to use, flexible and rapid to shift, easy to manufacture and easy to accept by bicycle enthusiasts and can particularly realize quick shifting under various road conditions.

Description

technical field [0001] The invention relates to a bicycle in a vehicle, and more particularly to a bicycle with a miniature box-type transmission on the center shaft. Background technique [0002] Bicycle, also known as bicycle or bicycle. At present, although there are many types of bicycles, bicycles are mainly composed of frame, tires, pedals, brakes, chains and other components. According to the working characteristics of each component, it can be roughly divided into: frame device, transmission device, Mobile devices, security devices. The transmission device includes pedals, cranks, sprockets, chains, central shafts and flywheels, etc. The pedals are stepped on by manpower, and the wheels are driven to rotate through the transmission parts to drive the car forward. At present, the transmission speed ratio of bicycles has two types: fixed speed ratio and adjustable speed ratio. For bicycles with adjustable speed ratio, most of them use a plurality of flywheel chainrin...
