Embodiment Construction

[0008] figure 1 As shown, the schematic diagram of the main components of a three-wheeled bicycle consists of at least three wheels, one of which is in direct contact with the ground, and utilizes a pedal gear set to transmit power. The movement of the three-wheeled bicycle can be promoted by using the middle wheel B to directly contact and roll with the ground, and the translation trend of the middle wheel B and the ground can also be used to push the three-wheeled bicycle forward. pedal gear set Figure 2-Figure 4 It is a device that generates power. Among them, 1 (main gear) transmits torque to 2 (pinion gear) through 10 (drive shaft) under the action of pedal crank (11), and 2 (pinion gear) rotates coaxially with 3 (elliptical gear), and transmits torque to 4 (flywheel), the flywheel is fixed with 5 (hub), and drives 5 (hub) to rotate so that the middle wheel (B) produces a rotating motion to make the tricycle move forward. 6 (ellipse wheel) rotates coaxially with 3 (el...

Abstract

The invention relates to a bicycle. The tri-wheeled bicycle is formed by three or more wheels, and at least comprises a front wheel, a middle wheel, a rear wheel, a bicycle body, a bicycle seat and a handle, wherein a crank and pedals are directly mounted on a wheel shaft of the middle wheel; the transmission of a gear group enables the middle wheel to rotate; the middle wheel can move back and forth under the action of a connecting bar. The tri-wheeled bicycle has the advantages of improved mechanical efficiency, labor economization and great improvement on speed.

Description

technical field [0001] The patent of the invention relates to a bicycle, especially a high-speed and labor-saving tricycle. Background technique [0002] At present, bicycles are mainly based on two wheels, driven by a chain, and the speed of rotation of the wheels determines the speed of the bicycle. The mechanical efficiency is low, the speed is slow, and it is laborious, and the chain is prone to failure. Contents of the invention [0003] The object of the present invention is to provide a bicycle with high speed, high mechanical efficiency and labor saving. [0004] Technical solution of the present invention is as follows: [0005] 1. A bicycle, comprising a front wheel, a middle wheel, a rear wheel, a vehicle body, a seat, and a handlebar. 2. The bicycle as described in technical solution 1, wherein the crank and the pedal are directly installed on the axle of the middle wheel, and the middle wheel is driven to rotate through gears and connecting rods, and the mid...
