Abstract

Disclosed are a front drive module and a folding bicycle assembled by the front drive module. According to the front drive module, a crank drives a shaft of the front drive module, a drive gear, a driven gear, a transmission shaft, a follower gear and a second driven gear to rotate, the drive gear, the driven gear, the transmission shaft, the follower gear and the second driven gear are arranged on the shaft, an activity iron pit is arranged on the outer edge of the second driven gear, fly wheel activity iron in the pit is meshed with fly wheel teeth under the action of a spring to drive a wheel on a wheel axle to rotate, a module outer shell is also used as a single side supporting leg of a front drive wheel, an assembling port is arranged at the upper end of the module outer shell, the port is fixed at the front end of a bicycle beam through four screws, the single side supporting leg used for supporting a steering wheel is connected at the rear end of the bicycle beam, and a handlebar and a bicycle seat are arranged on the bicycle beam.

Description

The folding bicycle of before driving module and assembling thereof

Technical field

The present invention relates to the bicycle field, a kind of folding bicycle of f-w-d rear-axle steering of modular design assembling.

Background technology

Common people are exhausted and are thought to exhaust worry, intention allows the tourist carry a kind of instrument, going down flight, train number takes out just at once to ride from luggage and goes down town or landscape is gone sightseeing, not only soon but also light, but existing folded bicycle is on all functions, the requirement of out of reach portable far away, lost on the contrary the speed of non-folded bicycle with steady, practical, therefore, the folded bicycle non-modular designs is difficult the requirement that realizes travelling and carry.

Summary of the invention

Accommodating in order to go out, as only to remain in order to leave the descendants for some living environments the invention provides the folding bicycle that a kind of modular design is assembled.

the technical solution adopted for the present invention to solve the technical problems is: the before driving module is that crank drives the driving gear on its axle and axle, ring gear, transmission shaft, driven gear and the second ring gear rotate, the outer rim of the second ring gear is provided with iron nest alive, flywheel in nest iron alive is meshing with flywheel teeth under the effect of spring, vehicle wheel rotation on live axle, module housing doubles as the one-sided supporting leg of front driving wheel, the upper end is provided with the assembling interface, interface is fixed in car beam front end with 4 screws, the Che Liang rear end connects the one-sided supporting leg that supports wheel flutter, establish handlebar above the car beam, car is sat.

The invention has the beneficial effects as follows: module turns to the design of folding bicycle and has opened up wide space, simple machinery has incorporated artistic connotation, people's life, trip have had the raising of matter, carry-on portable, stochastic transformation by bus by bike, on foot,, be really the Hot Wheels that ancients dream of, the fat that burnt, strong physique.
