Problems solved by technology

Bicycles with traditional driving methods have some disadvantages: (1) The human body is used to exert force in the up and down direction when riding a bicycle. A large part acts on the axial direction of the crank, and only a small part of the force forms a moment to make the crank rotate, and the utilization efficiency of the human body's force is low

Abstract

The invention discloses a wheel drive device which comprises a wheel, a support, a force applying rod, a chain wheel frame, a first chain wheel, a second chain wheel, a third chain wheel, a fourth chain wheel, a fifth chain wheel, a first chain and a second chain. The support is fixedly connected with a central spindle of a wheel hub. An inner ring of the fifth chain wheel is fixed to a hub shell of the wheel hub. One end of the force applying rod is connected to the support through a rotating pair. The chain wheel frame is fixed onto the force applying rod. The inner rings of the first chain wheel, the second chain wheel, the third chain wheel and the fourth chain wheel are all fixed onto the chain wheel frame. The first chain is mounted on the first chain wheel and the second chain wheel. The second chain is mounted on the third chain wheel and the fourth chain wheel. The first chain and the second chain are mounted in parallel. The fifth chain wheel is located between the first chain and the second chain and is engaged with both the first chain and the second chain. The force applying rod is equivalent to a lever with the rotating pair serving as a fulcrum, the drive force can be amplified through the lever mechanism, and the technical effect of labor saving can be achieved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a wheel driving device. Background technique [0002] A bicycle, also known as a bicycle or a bicycle, is usually a small land vehicle with two wheels. After a person rides on the vehicle, it is powered by pedals. It is a green and environmentally friendly means of transportation. Common bicycles are all arranged in front and rear of two wheels, and the drive system is composed of pedals, central shaft, crankset, crank, chain, flywheel, rear axle, rear wheels and other components. The pedaling force of people's feet is driven by the pedals through cranks, sprockets, chains, flywheels, rear axles and other components, so that the bicycle continues to advance. Bicycles with traditional driving methods have some disadvantages: (1) The force direction of the human body when riding a bicycle is the up and down direction, and when the pedals rotate to the vertical state, the force issued by the...
