Abstract

The invention discloses a lever ratchet wheel linkage bicycle, comprising a bicycle frame, a front bicycle wheel, a rear bicycle wheel, a rear wheel shaft and a bicycle wheel drive device, wherein, the bicycle wheel drive device comprises a left lever and right lever up-to-down conversion device and a left ratchet wheel and right ratchet wheel drive device, wherein, the left lever and right left up-to-down conversion device comprises a lever, a lever connector, a frame connector, a sun wheel, a planet wheel, a gear ring and a central shaft; and the left ratchet wheel and right ratchet wheel drive device is a friction-type ratchet wheel mechanism comprising a roller, a slope-type one-way clutch, a ratchet wheel hub and a ratchet wheel connector. In the invention, the drive, speed change and the acting force are wholly centralized on the rear wheel shaft to lead the length of the lever to be 3-5 times of a crank mechanism; the lever can be retracted; a seat cushion can be moved front and back; the pedal rotating angle of both feet is changed to form the action of stepless speed regulation; and the speed is changed by a star wheel structure, so as to lead the transmission to be compact and the operation to be reliable. The invention provides a bicycle which is brand new, has simple structure, high transmission rate, long service life, low failure rate, convenient maintenance and comfort and stable riding.

Description

technical field

[0001] The invention relates to a bicycle, in particular to a bicycle with lever and ratchet linkage. Background technique

[0002] Bicycle neither consumes energy nor causes environmental pollution, so it is a good means of transportation. Yet, so far, the bicycles on the market all adopt the driving structure of crank and sprocket, and there are many circular movable parts, and the failure rate is high. 200910134864.1, which has made great improvements to the above defects, discloses a lever-cam linkage bicycle, which completely abandons the crank linkage mechanism and related components, and replaces the traditional driving method with the up and down motion of both feet. In principle, a lever ratchet mechanism is proposed to solve the problems existing in the drive structure of the crank and the chain wheel. However, its structure is still relatively complex, and requires high precision, easy to wear, and difficult to adjust and repair. The service lif...
