Bicycle driving mechanism and bicycle

Abstract

The invention relates to a bicycle driving mechanism and a bicycle, the driving mechanism comprises a left output shaft, a right output shaft and a gear set coupler, a left crank and a left crank chain wheel are fixedly arranged on the left output shaft, a right crank and a right crank chain wheel are fixedly arranged on the right output shaft, and flywheels are respectively arranged on two sides of a rear axle. The left crank chain wheel and the right crank chain wheel are respectively connected with the flywheels on the corresponding sides through chains; the gear set coupler is connected with the left output shaft and the right output shaft, and enables the rotation directions of the left output shaft and the right output shaft to be opposite. The bicycle uses the driving mechanism. According to the bicycle driving mechanism provided by the invention, the left half shaft and the right half shaft of the middle driving shaft can be in a synchronous reverse rotation state, alternate treading and power generation of left and right feet are realized, cranks are prevented from reaching 'dead points', continuous exertion for riding can be realized, and the treading efficiency is improved.

Description

technical field [0001] The present invention relates to a bicycle driving mechanism and a bicycle including the driving mechanism. Background technique [0002] The driving mechanism of the existing bicycle is to fix two cranks through the two ends of the center shaft, and use a crank sprocket fixed on one of the cranks as the driving sprocket, and drive the driven sprocket of the rear wheel or front wheel through the chain. Drive, wherein the two cranks are set in opposite directions (180 degrees), when one crank is forced to turn downwards, the other crank is passively turned upwards under the action of the central axis, the two cranks alternately exert force, and ride When running, the two cranks do circular motion. [0003] This kind of driving mode makes the bicycle have a point of fatigue during riding, that is, when the two cranks are perpendicular to the horizontal direction, the torque of the pedal acting on the center shaft is zero at this time, and it needs to re...

AI Technical Summary

Problems solved by technology

[0003] This kind of driving mode makes the bicycle have a point of fatigue during riding, that is, when the two cranks are perpendicular to the horizontal direction, the torque of the pedal acting on the center shaft is zero at this time, and it needs to rely on inertia or rely on The rider adjusts the action or uses the friction of the sole to make the pedal drive the crank to make a transition, but during this transition, the rider cannot rely on the pedal to generate force to output power to the bicycle

[0004] For example, when starting a bicycle, it is often necessary to adjust the crank to the horizontal direction before starting, but if the crank is in the vertical direction, the rider cannot exert force and cannot start

In addition, when the pedals are pressed to the point of exhaustion during the climbing process of the bicycle, the speed of the bicycle will drop quickly and even stop. It is an unavoidable problem when the crank is driven in a circular motion
