Abstract

The invention discloses a double-crank connecting rod reciprocating bicycle, including a double-crank connecting rod mechanism and a speed variator, wherein the double-crank connecting rod mechanism includes a fixed chain wheel, a chain, a chain wheel, a chain wheel shaft, chain wheel seats, an eccentric wheel, an eccentric shaft, a frame connector, a central shaft, a connecting rod and a lever; the fixed chain wheel is fixedly connected with a cylindrical part on the frame connector by a flat key, the chain is connected with the fixed chain wheel and the chain wheel, the chain wheel and the chain wheel shaft are fixedly installed between the chain wheel seats, one end of the chain wheel shaft is fixedly connected with the eccentric wheel, the eccentric shaft is fixed at the eccentric center of the eccentric wheel and movably connected with the connecting rod, the other end of the connecting rod is movably connected with the lever, and the middle front part of the lever is movable connected with the frame; the bicycle is novel and unique in whole design; and the bicycle which is brand new, reliable in work, simple in structure, high in transmission efficiency, long in service life, comfort and stable in riding is provided.

Description

technical field [0001] The invention relates to the field of bicycles, in particular to a double crank connecting rod reciprocating bicycle. Background technique [0002] Existing bicycle, along with the development of the times, has all had very big improvement to the outward appearance of bicycle, manufacturing material, speed change device, but drive core does not change, is the circular motion of wheel by the circular motion of pedal. CN103204213A, which has made great improvements to the above defects, discloses a lever reciprocating drive mechanism and a bicycle including it, which completely abandons the central axis and related components, and replaces the traditional drive method with the up and down motion of both feet. In principle, it is proposed to use the lever ratchet mechanism to solve the problems existing in the crank drive structure, but its structure is still relatively complicated, and requires high precision, and it is difficult to adjust and repair. ...
