Double-crank rocker bicycle

Abstract

The invention discloses a double-crank rocker bicycle. The double-crank rocker bicycle comprises a right treadle, a right bicycle turning component, a right rocker, a right connecting rod, a large crankset, a chain, a flywheel, a left connecting rod, a left rocker, a left bicycle turning component and a left treadle. The chain winds through the large crankset and the flywheel. The large crankset is a main transmission piece, a left crank and a right crank are arranged on the two sides of the large crankset separately, and the right crank is hinged to the right connecting rod. The right connecting rod is hinged to the right rocker, the right rocker is fixedly connected with the right bicycle turning component, and the right treadle is arranged on the right bicycle turning component. The left crank is connected with the left connecting rod in a hinged mode, the left connecting rod is hinged to the left rocker, and the left rocker is fixedly connected with the left bicycle turning component. The left treadle is arranged on the left bicycle turning component. According to the double-crank rocker bicycle, the driving mode of a traditional bicycle is changed; and the double-crank rocker bicycle accords with the law of human body kinematic mechanics, so that fatigue feeling of bodies is relieved, and long-distance riding is achieved.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a double crank rocker bicycle. Background technique [0002] At present, most of the known bicycles are driven by the large chainring of the central shaft of the bicycle through the chain to drive the pinion on the rear wheel shaft to walk. The length from the center of the large chainring to the pedal is actually the lever arm in the principle The chain only plays the role of transmitting force. The disadvantage of this driving method is: between 12 o'clock and 3 o'clock, the legs need to generate a component force of the forward dial; this component force drives the big crankset to rotate, which is The main factor of leg fatigue is that between 6 o'clock and 12 o'clock, the legs must make a circular motion with the pedals. At this time, the legs do not do work on the big chainring, which will also cause fatigue in the legs; the driving principle of the left pedal is the same a...

[0002] At present, most of the known bicycles are driven by the large chainring of the central shaft of the bicycle through the chain to drive the pinion on the rear wheel shaft to walk. The length from the center of the large chainring to the pedal is actually the lever arm in the principle The chain only plays the role of transmitting force. The disadvantage of this driving method is: between 12 o'clock and 3 o'clock, the legs need to generate a component force of the forward dial; this component force drives the big crankset to rotate, which is The main factor of leg fatigue is that between 6 o'clock and 12 o'clock, the legs must make a circular motion with the pedals. At this time, the legs do not do work on the big chainring, which will also cause fatigue in the legs; the driving principle of the left pedal is the same as that of the right foot. The pedaling is the same; during the rotation of the big chainring, three-quarters of the movement of the human leg is not in the best force state, which does not conform to the laws of human motion mechanics
