Problems solved by technology

These defectives are: 1, the three-wheeled bicycle of two-wheel front and one rear is easy to exceed the triangular region formed by three-wheel landing sites because of the rider's center of gravity and overturns
The front-wheel drive will cause difficulty in pedaling when turning sharp or large bends; the rear-wheel drive is currently widely used in chain transmission, which has low t

Embodiment Construction

[0023] Such as figure 1 , Figure 3-4 Among them, a three-wheeled bicycle with pedal gear transmission includes a vehicle body 1, a handlebar 4, a front wheel 2, a rear wheel 3 and a seat 7, and the central shaft 26 of the two rear wheels 3 is connected with a differential 30, and the differential 30 Both sides are respectively provided with a transmission gear 9, the transmission gear 9 is connected with the differential 30 through the one-way ratchet 28 which can be emptied, and each transmission gear 9 is connected with a large gear 8 installed on the vehicle body 1 through the large gear support 10 respectively. Forming an internal meshing fit, each large gear 8 is fixedly connected to pedals located on both sides of the vehicle body 1 for driving the large gear 8 to reciprocate. Bull gear 8 in this example is relative to transmission gear 9. Such as Figure 4 Among them, a sleeve shaft 27 is sheathed on the outside of the central shaft 26, and the sleeve shaft 27 is us...

Abstract

A pedal gear transmission tricycle comprises a body, handlebars, a front wheel, rear wheels and a seat; a center shaft of the two rear wheels is connected with a differential mechanism; two transmission gears are arranged on the bilateral sides of the differential mechanism respectively; the transmission gears are connected with the differential mechanism through nullable ratchet wheels; each transmission gear is meshed with and matched with a large gear; the two large gears are fixedly connected with pedals which are located on the bilateral sides of the body respectively and used for driving the large gears to rotate in a reciprocating mode. According to the pedal gear transmission tricycle, the driving can be labor-saving, the transmission is reliable, and the turning can be flexible due to the differential mechanism; the reciprocating motion pedal driving mode can be possible due to a ratchet wheel mechanism and the internal meshing combination structure; compared with the pedal mode in the prior art, the working of the mechanism is located in the state that a human body is easy to exert force and accordingly the driving efficiency is improved.

Description

technical field [0001] The invention relates to a three-wheeled bicycle, in particular to a three-wheeled bicycle with pedal gear transmission. Background technique [0002] Tricycle is a kind of important, environment-friendly transportation, shopping, body-building, leisure tool to the vast middle and old people whose balance ability is weakened year by year. But existing three-wheeled bicycle is not widely used because of having some defects. These defectives are: 1, the three-wheeled bicycle of two-wheel front one-round rear position easily surpasses the triangular region formed by three-wheel landing sites because of the rider's center of gravity and overturns. If two front-wheel distances are widened or the front and rear wheel distances are lengthened, although the above-mentioned defects can be improved to some extent, the vehicle body is huge and difficult to store. 2. A bicycle with one front wheel and two rear wheels can be divided into front-wheel drive and rea...
