Problems solved by technology

[0002] In the prior art, the bicycles and electric power-assisted bicycles we use are all two-wheeled, and the two fulcrums on the same straight line make the stability of the two-wheeled bicycles poor. The two fulcrums become three fulcrums on the surface to increase the stability of the vehicle, so the linkage steering of the two front wheels requires a safe and reliable method to realize

Embodiment Construction

[0028] See the structure of this embodiment figure 1 , figure 2 , Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, Figure 8, Figure 9, Figure 10, Figure 11, the linkage steering mechanism 16 device of the bicycle, consists of two upper and lower triangular splints 1 and three outer The support tube 2 constitutes a support frame. The three outer support tubes 2 are pressed into the circular holes of the outer support tubes 2 punched out of the upper and lower triangular splints 1 and welded, and the 19-position outer support tubes 2 of the handlebars are welded to the frame 6. The two front forks 20 are installed in the same parallel position and the outer support tube 2 is adjusted and fixed up and down by a combined bearing 4. The bottom of the handlebar 19 installation position rotating tube 21 is welded with a rotating tube tray 3 supporting the lower combined bearing 4, and the handlebar 19 installation position rotating tube 21 is inserted into the handlebar 19 outer suppor...

Abstract

A reciprocating-driven and linkage turning bicycle is safe, saves labor and belongs to manual transport technology. Two front wheels are coiled with handlebar by three small turning sprockets and chains to acting one by one, and tensioner swells chain to forming a reliable turning way in same direction and angle. The chair which height is suitable helps people buttress handlebar rather than press handlebar when riding. The reciprocating-driven devices with long arm of force helps bike riders sit on the chair comfortably and drive easily with the feet's tiny action of extending onwards. Due to high stability of three wheels, it is fit for middle-aged and old persons without the worry about rain and snow.

Description

Technical field [0001] The invention relates to a linked steering reciprocating drive safe and labor-saving bicycle, which belongs to the technical field of manpower vehicles. Background technique [0002] In the prior art, the bicycles and electric-assisted bicycles we use have two wheels. The two fulcrums on the same straight line make the stability of the two-wheel bicycle poor. Two fulcrums become three fulcrums on the surface to increase the stability of the vehicle, so that the linkage steering of the two front wheels requires a safe and reliable method to achieve. The driving performance of a two-wheeled bicycle is poor, and the riding effort is related to the driving mode. The circular driving mode of the crank enlarged wheel makes the rider's two legs have a large difference in height and low position, and the effective driving angle is very small. Changing the drive of the small moment arm into the drive of the long moment arm, so that the two legs can drive the bicycle...
