Double-flight linkage longitudinal riding lever-type driving device for bicycle

Abstract

The invention discloses a double-flight linkage longitudinal riding lever-type driving device for a vehicle, and belongs to the technical field of bicycle manufacturing. The double-flight linkage longitudinal riding lever-type driving device is structurally composed by a device shell, a bearing pedestal, middle shafts, driving rods, belts, springs, rotary wheels, cranks and the like, and all the parts are connected with one another. The double-flight linkage longitudinal riding lever-type driving device is novel in structure and has a clear working principle; through longitudinal swinging of the left crank and the right crank, the middle shafts are driven to rotate; through the middle shafts, the driving rods are driven to swing longitudinally; through the driving rods, the belts are driven to retract, and through the spring, the rotary wheels are driven to be restored. Compared with a traditional bicycle driving structure, the double-flight linkage longitudinal riding lever-type driving device can achieve single-side separate driving and double-side alternating driving, during driving, a pedaling looping action mode in the prior art is changed into a longitudinal acting mode, after pedaling, the springs are automatically restored, the problem that when a bicycle is driven traditionally, a middle gear causes a lot of trouble is solved, the physical power of a rider is saved, and the riding efficiency is further improved; moreover, the double-flight linkage longitudinal riding lever-type driving device is convenient to operate, and the riding requirements of different peopleare further met, particularly people with disabled legs.

Description

technical field [0001] The invention belongs to the technical field of bicycle manufacturing, and relates to a bicycle driving device, in particular to a double-fly linkage up and down riding lever type driving device for bicycles. 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, and 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 t...

Problems solved by technology

[0004] The present invention aims at driving the traditional bicycle through the pedals in circles, and the crankshaft is driven by the central shaft. However, when the crank is in the same direction as the gravity during the pedaling process, the driving efficiency is low, the pedaling is laborious, and it is easy to cause the rider’s fatigue, which is not conducive to Exercising the body will cause pain in the buttocks and legs. A double-fly linkage up and down riding lever drive device for bicycles is proposed. By changing the structure of the device and the way of pedaling, the rider's physical strength can be saved, which can be further improved. Meet the riding needs of different groups of people and further improve riding efficiency
