Embodiment Construction

[0013] exist image 3 Among them, install the transmission small sprocket 8 and the bearing 12 on the position made by the drive shaft 7, install the transmission large sprocket 10 and the bearing 12 on the position made by the driven shaft 11, and use the transmission chain 9 to connect them After being connected in series, it is placed in the custom-made position of the transmission 6 box, and the transmission is closed and assembled. The transmission ratio of the large and small sprockets of the transmission is about 1:1.5, so that the transmission has the characteristics of a reducer, thereby improving output power. Pedal and crank 1 are installed on the two ends of the external driving shaft of the transmission, and the bicycle sprocket is installed on the outer end of the external driven shaft of the transmission.

[0014] exist figure 2 In the process, the driver 6 is installed on the bicycle rack through the driver fixing hole 13 with screws, and the bicycle chain 3...

Abstract

The invention provides a back transmission device with the advantages that the structure is simple, and the defect of labor waste during the riding of an ordinary bicycle can be overcome, so the riding of the bicycle is labor-saving. A small chain wheel is arranged on a driving shaft in the transmission device, and is connected with a large chain wheel arranged on a driven shaft through a chain, the transmission ratio of the large chain wheel to the small chain wheel is about 1:1.5, and the small chain wheel is used for driving the large chain wheel to rotate, so the principle of output torque force increase of a speed reducing machine is realized. The transmission device is arranged on a bicycle frame, pedals and crank handles are arranged at the two ends of a driving shaft arranged inside the transmission device, a bicycle chain wheel is arranged at the outer end of the driven shaft and is connected with a flywheel through a bicycle chain, and the bicycle transmission running is completed, so the pedaling times and driving shaft rotating speed are respectively and properly increased and accelerated, and the increase of the output force of the bicycle chain wheel is realized, so the riding of the bicycle is labor-saving.

Description

[0001] belongs to the technical field [0002] The invention relates to a rear transmission device of a bicycle, in particular, the structure is relatively simple, and the bicycle can be ridden with labor-saving. Background technique [0003] At present, bicycles are divided into two-wheeled and three-wheeled, and there are many kinds of ordinary bicycles, mountain bikes, three-wheeled leisure and cargo bicycles, etc. Electric bicycles are also equipped with pedal transmission, which is more laborious when riding. At present, bicycles generally use chain-connected rear transmission. The rear transmission is mainly composed of pedals and cranks, sprockets, chains, flywheels, etc. The principle of bicycle rear transmission is to step on the pedals hard, and the crank drives the sprocket to rotate. Drive the flywheel and the rear wheel to rotate through the chain, and push the front wheel to make the car move forward. Mountain bikes are driven by chains and rear wheels. Adjustin...
