Problems solved by technology

[0005] The present invention aims at driving the traditional bicycle through the looped pedals, driven by the central shaft to drive the tooth plate. When the crank is in the same direction as the gravity during the pedaling process, the driving efficiency is low, and the pedaling is laborious. If an additional device is added, the device structure will be complicated. Due to the high manufacturing cost, which affects the riding effect, etc., a chainless double-fly linkage lever direct-drive bicycle is proposed. The structure of the bicycle is simpler, and the riding is more labor-saving, which can further improve the riding efficiency.

Abstract

The invention discloses a chainless double fly linkage lever direct drive bicycle, and belongs to the technical field of bicycle manufacturing. Flywheels and sheaves in the same direction are arrangedon both sides of the rear axle of the bicycle, inner grooves for placing wire ropes and outer grooves for placing belts are formed in the sheaves, fixing hinge chains for lever fulcrums are arrangedin the middle and rear portions of the left crank and the right crank, the left and right cranks are alternately rotated and revolved around the fixing hinge chains, the forced reset of the left and right cranks is achieved by the wire rope linkage, the sheaves are driven by the belts to drive a rear wheel to rotate, the structure is novel, and the driving principle is clear. Compared with a traditional bicycle structure, it is not necessary to provide components such as chains, center shafts, gear wheels, chains and chain guard plates, which not only does not cause the chains to fall off, butalso saves manufacturing costs, the problem of a tradition bicycle driving dead position is laborious is solved by the lever principle, the riding is very labor-saving, and the riding efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bicycle manufacturing, and relates to a bicycle with a new driving mode, in particular to a chainless double-fly linkage lever direct-drive bicycle. Background technique [0002] my country has a large population and is a country with a large number of bicycles. Bicycles are an indispensable part of urban traffic. Using bicycles has the following advantages: (1) There is no air and noise pollution, and it can provide convenient transportation for residents and tourists. The green way of travel can improve the city's green competitiveness. At the same time, cycling can also help to strengthen the body and reduce the occurrence of urban diseases; (2) provide the city with a short-distance travel solution of 1-5 kilometers to improve the utilization rate of road resources , relieve road traffic congestion, and solve the problem of "the last mile" of public transportation; (3) Compared with buses, bicycles have...
