Abstract
The utility model relates to a chainless gear-driving bicycle, which belongs to a bicycle, particularly a gear-driving bicycle without chains. The utility model is provided with handles, a front and a rear wheels, and a seat plate; two chainless flywheels with slots are arranged on a shaft of the rear wheel; levers connected by steel cables are arranged at both sides of the bicycle frame; one end of each of the two steel cables respectively fixed to the two levers passes through a fixed pulley and winds on the fly wheels; the other end is fixed to the slot walls of the fly wheels; return springs are arranged between the outer slot walls of the fly wheels and the bicycle frame. A left lever under a left pedal drives the left chainless flywheel with slots to rotate; the steel cable of the left chainless flywheel with slots is released out; the rear wheel rotates forwards; power acts on the left return spring, and the right lever is lifted up; the right return spring returns, and the right chainless flywheels with slots winds back the steel cable; the right lever under the right pedal does opposite action; the action is carried out repeatedly; the rear wheel continuously rotates so that the bicycle runs forwards. The utility model has the advantages of a few components, simple structure and lightness, has no condition that chains hurt people and is suitably made into a folding bicycle and a pedal bicycle for children.
Description
Technical field
The utility model relates to a kind of bicycle, and is particularly a kind of without chain, gear-driven bicycle.
Background technology
Existing bicycle is made of handgrip, front and back wheel, chain, gear, seat, stretcher etc., and it is by chain, gear transmission.When running, the cyclist uses foot pedals, and the miniature gears on the band tooth flywheel by being adorned on the pedal shaft, chain, the hind axle drives rear wheel and rotates, thereby wheel is run forward.Because of this car by chain, gear transmission, when the head of a family often occurring and carrying small children, child stretches into pin in the chain because of carelessness, and causes leg, pin injured.In addition, also there are problems such as complex structure, weight be big in this bicycle.
Existing people designs the bicycle with lever, steel cable transmission, as " a kind of double sided gear transmission bar rod-type bicycle " (patent No. 98213581), the rotation end of lever is installed in both sides, vehicle frame rear portion, steel cable fixed pulley group is equipped with in the vehicle frame front portion, the lever force side is contained on the steel cable, the also hinged connecting rod in lever rear portion, the connecting rod other end is hinged on big gear wheel off-center place, big gear wheel and the pinion that is fixedly connected on wheel steel wire tube." back transmission bar rod-type bicycle " (patent No. 00244991), the rotation end of lever is installed in both sides, vehicle frame rear portion, lever is by drive links driving wheel and trailing wheel, the vehicle frame front portion is equipped with steel cable fixed pulley group and is connected lever, and a driving wheel is housed above trailing wheel, and driving wheel is fixed with two cranks, link rod on the lever of both sides is hinged cooresponding crank respectively, and driving wheel is connected in the flower wheel with the same rotating shaft of trailing wheel.This bassinet structure is simple, can eliminate the dead point of crank-bar linkage transmission well, installs and makes easily, and it is laborsaving to ride, and speed is fast, driving efficiency height, long service life.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aim to provide a kind of simple in structure, parts are few, in light weight, no chain, gear-driven bicycle that chain is caused injury can not appear.
The implementation of the utility model purpose is, no chain, gear-driven bicycle, handgrip 1 is housed on the vehicle frame 2, front and back wheel, seat 4, two troughs of belt are housed on rear vehicle shaft 9, anodontia flywheel 8, be equipped with on the vehicle frame both sides can be along the lever 3 of axle rotation, two steel ropes, 6 one ends are separately fixed on two levers 3, after walking around the fixed pulley 5 that is contained on the vehicle frame respectively, on flywheel around several circles, the other end is fixed on the flywheel cell wall, and pull back spring 10 1 ends are fixed on the flywheel external groove sidevall, and an end is fixed on the vehicle frame 2, connect with another steel rope 12 of walking around fixed pulley 11 between two levers, fixed pulley 11 is fixed on the vehicle frame.
When using the utility model, step on two levers 3 with the pin branch, foot-operated power reaches trough of belt, anodontia flywheel 8 by two steel ropes 6, and trough of belt, anodontia flywheel 8 rotate, and drive back wheels of vehicle thus and rotate, thereby wheel is run forward.
The utility model does not have chain, gear, stretcher, and parts are few, simple in structure, in light weight, the situation that chain is caused injury can not occur, and suitable for making folded bicycle and children scooter voluntarily.

Fig. 3 is a connection diagram between two levers
The specific embodiment
With reference to Fig. 1, the utility model has handgrip 1, front and back wheel, seat 4, two troughs of belt, anodontia flywheel 8 are housed on rear vehicle shaft, be equipped with on the vehicle frame both sides can be along the lever 3 of axle rotation, two steel ropes, 6 one ends are separately fixed on two levers, after walking around the fixed pulley 5 that is contained on the vehicle frame respectively, around youngster's circle, the other end is fixed on the flywheel cell wall on flywheel.
With reference to Fig. 2,3, reinstall a spring 10, two levers between flywheel external groove sidevall, vehicle frame and ask that the steel rope 12 of walking around fixed pulley 11 connects, fixed pulley 11 is fixed on the vehicle frame.
When using the utility model, the people is sitting on the seat 4, lever left under the left threading, by steel rope 6 drive left trough of belt, anodontia flywheel rotates, on left trough of belt, the anodontia flywheel around steel rope emit, rear wheel rotates forward, a left side pull back spring epipodium strength, because of steel rope 12 connections of walking around fixed pulley 11 are arranged between two levers, so right lever is lifted by steel rope 12, right pull back spring resets the steel rope wraparound that right trough of belt, anodontia flywheel are emitted.Right threading bottom right lever, action is opposite, carries out so repeatedly, rear wheel can continuously be rotated, thereby bicycle is run forward.
