Reciprocating stepless labor-saving bicycle

Abstract

The invention discloses a front drive reciprocating type stepless labor-saving bicycle which comprises existing components. A shaft sleeve is welded at the front end of a frame and is close to the rear of the front end of the frame, a flywheel is fixed to one ends of bearings via an axial bar, and a chain wheel and another flywheel are fixed to the other ends of the bearings; a bearing pulley is connected to the outer periphery of a front fork barrel in a sleeved manner; a left lever and a right lever of pedals are connected onto the frame and the lower ends of the two flywheels; a chain comprising steel wire ropes is arranged in the middle sections of the flywheels, is wound around the bearing pulley to be meshed with two rear ends of the two flywheels and is connected with rear positions of the front ends of the two levers; a reducing driving wheel is arranged at the right end of the axis of the frame, and a pinion of the reducing driving wheel is connected the chain wheel by a chain, and a gear wheel of the reducing driving wheel is connected with a rear-circle flywheel by another chain. The front drive reciprocating type stepless labor-saving bicycle has the advantages that the stepping cycle can be shortened, riding acceleration can be facilitated, circulation disappearance of a moment arm lever effect can be prevented, power consumption can be halved, a moment arm is triple a resistance arm, a large quantity of power can be saved, and the pedals can slide along the levers, so that the speed can be steplessly changed, and a labor saving effect is better than a labor saving effect of a speed-variable bicycle; the requirement on riding power can be met by the gravity of the two legs of a rider, so that the rider does not feel tired, the front drive reciprocating type stepless labor-saving bicycle is applicable to long journal and favorable for jam decrease, emission reduction, energy conservation and low-carbon life, and great economical and social benefits can be realized.

Description

technical field [0001] The invention is a reciprocating labor-saving bicycle. Background technique [0002] With the continuous increase of motor vehicles leading to serious road congestion, the advantages of bicycles are light, flexible, and small, occupying less road resources and not being restricted by road police in turn, and can cross congested streets and alleys. However, its rotating pedal method has too much power Short and vertical circulation disappears the lever effect of the arm, resulting in laborious and slow uphill and lack of strength and manpower is difficult to meet the shortage of long-distance riding. Contents of the invention [0003] The purpose of the present invention is to provide a reciprocating stepless labor-saving bicycle for solving all the above-mentioned deficiencies. The reciprocating stepless labor-saving bicycle includes the existing components of the bicycle; a shaft sleeve is welded to the rear of the front end of the bicycle frame, a...
