Pedal, electric, solar three-wheel drive bicycle without chain gear transmission

Abstract

The invention provides a chainless gear drive bicycle capable of integrating pedaling drive, electric drive and solar drive. The chainless gear drive bicycle comprises an adjustable handlebar, a handlebar stem, a frame, a front wheel, a rear wheel, a gear drive mechanism, a motor power mechanism and a solar power mechanism. The chainless gear drive bicycle is characterized in that two circles of inner teeth large gears are arranged in an inner ring of a hub of the rear wheel and meshed with a pair of driven large outer gears in the gear drive mechanism for driving, the effect that the ratio of driving force physical torque to ground frictional resistance torque is maximum is achieved, the frame is designed according to human engineering, the handlebar is transversely, vertically, forwards and backwards adjusted, a prostration riding mode and a straight sitting riding mode can be converted, the effects of comfortable riding and the minimum wind resistance are achieved, manpower drive, motor drive and solar drive are scientifically and organically integrated, and the ideal effects of comfort, labor saving, multiple driving modes and the long driving mileage are achieved.

Description

technical field [0001] The invention relates to a novel bicycle, in particular to a pedal, electric and solar three-drive bicycle without chain gear transmission. Background technique [0002] Bicycle is the means of transportation commonly used by people, and is liked by people with simple structure, easy to use. There are many types of bicycles in the market, such as riding bicycles sitting upright, riding bicycles lying on their backs, chain drive bicycles, etc., but there is a single power in the above-mentioned various bicycles, large wind resistance, and deficiencies such as effort. [0003] A Chinese utility model patent for a bicycle without chain gear transmission (application number 201120301800.9) discloses a bicycle without chain gear transmission. Skin, flywheel and rear axle, it is characterized in that: between described central shaft and rear axle skin, connect through gear transmission mechanism, described gear transmission mechanism comprises the driving g...

AI Technical Summary

Problems solved by technology

Although the bicycle without sprocket transmission is driven by gears, it is still the same as the traditional bicycle: firstly, the force of the driving gear is transmitted to the flywheel of the rear axle, and then the flywheel with small diameter (small torque) drives the large diameter (large torque) The rear wheels rotate, so it is still relatively laborious, and there are disadvantages such as high wind resistance when sitting upright, uncomfortable for a long time, and single power
