Abstract

The utility model relates to a bicycle with windmill system, which installs a windmill system on the front part of the existing bicycle. The windmill system is composed of a support bracket, a windmill and a driving device three parts. The bicycle using the utility model can make the rider to feel comfortable with labor saving by the aid of wind force. The effect is more obvious while riding close to the wind or the speed is high.

Description

Bicycle with windmill system

The utility model belongs to a kind of bicycle.

Existing bicycle has multiple, but its primary member all be by vehicle frame, wheel, handlebar, front and rear fork, saddle, pin step on, chain, gear, bearing and some other parts constitute.Make this bicycle operation, step on by manpower entirely.Use this bicycle to make the vehicle, the people relatively requires great effort, long distance running, and it is tired that the people will feel.Also have at present and a kind ofly a storage battery is installed on bicycle is done propulsion source,, bicycle is moved under the situation that manpower is stepped on less or do not stepped on certain mechanical mechanism transmission.But, on bicycle, add above these attendant equipments, bicycle weight is greatly increased, cost, cost improve greatly, and want storage battery as the energy.

The purpose of this utility model is to provide a kind of and can helps the bicycle operation, thereby make bicycle rider labour-saving bicycle by means of natural energy resources-wind energy.

Bicycle of the present utility model is exactly to load onto a small-sized windmill system in the front portion of existing bicycle, when driving by means of car and air between the air-flow of relative motion, the rotation of promotion windmill, this moment of rotation passes to wheel by certain mechanism, make it obtain additional moment, so can make bicycle rider feel light, laborsaving.

Bicycle fwd windmill of the present utility model system is made up of support, windmill, transmission device three parts.Whole windmill is contained on the handlebar of bicycle, as shown in Figure 1 by support.Fig. 2 is the constructional drawing of windmill system, and windmill is made up of blade (1), rotor (2) and cylinder (3).Blade has several, and cylinder (3) is fixed on the support (9), also can make one with support.The effect of cylinder has two, and the first keeps air-flow, improves windmill efficient; It two is to avoid people's clothing and blade to collide.Transmission device is made up of driving wheel (4), flower wheel (5), transmission shaft (6), power-transfer clutch (7) and blade wheel (8).Driving wheel is a crowngear, is fixed together it and rotor coaxial; Flower wheel also is a crowngear, and it and driving wheel vertically mesh, and no-load voltage ratio is decided according to the diameter of blade wheel.Transmission shaft is divided into upper and lower two sections, and is middle with the movable joint connection, so that regulate total length according to the setting height(from bottom) of handlebar.The bearing of rotor and driving wheel, the bearing of transmission shaft also is contained on the support.Power-transfer clutch can adopt any type of power-transfer clutch.The blade wheel of transmission device can be the rubber wheel, roller flower metal wheel or plastic wheel.The transmission device of whole windmill can also adopt flexible axle, hinge (universal-joint), and chain, belt, forms such as gear are transmitted energy.

During driving, air-flow is given blade with transfer of energy, and blade drives the rotor rotation, because rotor and driving wheel are fixed together coaxially, rotate so just drive driving wheel when rotor rotates, and driving wheel drives flower wheel.The power-transfer clutch that closes, this moment, blade wheel just in time was positioned at front vehicle wheel sidewall edge, and by means of producing certain pressure between the spring of power-transfer clutch and tire.When windmill rotates,, moment of rotation is become drive wheels forwards to the additional moment that rotates by means of the two-wheel friction.Thereby make people by bike laborsaving.

The utlity model has and utilize natural energy resources, make advantages such as bicycle rider is laborsaving, light.

Use bicycle of the present utility model against the wind or speed of a motor vehicle when higher, its effect is more remarkable.When the rider needs at a slow speed or sail with the wind, in the time of need be, can let the clutch be slipped by the windmill system.

Windmill system on the utility model also can be contained in the front portion of motor bike, thereby can make motor bike fuel-efficient.

Windmill system on the utility model can be used as bicycle part and makes separately, to offer the users of existing bicycle, is contained on the existing bicycle, thereby existing bicycle is transformed into the bicycle that has the windmill system.
