Description

The joint force bike

The utility model belongs to the bicycle of being with auxiliary engine.

Bicycle is a kind of short range vehicle light, durable, easy to use.Because the bicycle scanning frequency is low, and the physical efficiency that will consume the person of riding when travelling, so travelling of longer distance can make people's fatigue, especially when up-hill journey, more make the people feel painstaking.

Existing a kind of low-power electro car, by the electrical propulsion of institute's charged pool, alternative manpower drives exercises.But present this battery-driven car uses a large amount of batteries, and bearing a heavy burden increases, the body construction heaviness, and complete vehicle weight is big, and it is light to have lost bicycle, uses flexible characteristic; And there is fault to take place during this battery-driven car, eliminates day by day.

It is a kind of in conjunction with Electronmotive Force and muscle-powered light, the labour-saving joint force bike of rider that the purpose of this utility model is to provide.

The utility model joint force bike, contain vehicle frame, turn to handle, saddle, front-wheel, trailing wheel, pedal link via crank and center shaft, the center chain wheel is incorporated into center shaft, between center sprocket wheel and rear wheel sprocket, be to be associated with messenger chain, its special character is to establish motor on the car body, puts battery box that holds battery and the driven sprocket with driving action, drive sprocket is incorporated into machine shaft, is to be associated with messenger chain between drive sprocket and driven sprocket.

Establish driven sprocket on the said car body, be meant that this driven sprocket combines the formation one with the center sprocket coaxiality with driving action.

Establish driven sprocket on the said car body, be meant that also the coaxial heart engagement of this driven sprocket and rear wheel sprocket is disposed on this sprocket wheel with driving action;

Perhaps the coaxial heart engagement of this driven sprocket and trailing wheel central axle sleeve is disposed on this axle sleeve.

Establish driven sprocket on the said car body, be meant that again the coaxial heart engagement of this driven sprocket and front-wheel central axle sleeve is disposed on this axle sleeve with driving action.

Said battery, a kind of for chargeable lead-acid battery, ni-cd battery, nickel-hydride battery or fuel cell.

Said motor, its horsepower output are 1/35-1.5 horsepower, and its rotating speed is 0-1500 rev/min.

The utility model joint force bike, the configuration of the car body part except that battery box and motor, weight and existing general-duty bicycle are same or similar, again owing to car body is designed to travel with driven by power by the manpower driving is auxiliary, required its weight of the battery that carries is much smaller than the weight of existing storage battery car institute charged pool, so complete vehicle weight is light, can resemble to use the existing bicycle to drive and use this section force bike with manpower, keep characteristics easy to operate, this car adopts plumbic acid, ni-cd, batteries such as nickel-hydride a kind of, existing this chargeable plumbic acid, its energy density of ni-cd battery has 30-40wh/kg's, this battery of the general 2.5kg of loading just reaches one day use, set micro-machine, its weight is no more than 5kg, so complete vehicle weight is light.This car can add driven by power in travelling with the manpower driving at any time, as when going up a slope or make longer distance travel, can save muscle power greatly just add driven by power.This car also has simple structure, and cost is low, the characteristics of non-environmental-pollution in the use.

Below in conjunction with embodiment and respective drawings the technical solution of the utility model is described further.

Fig. 1. joint force bike-driven sprocket and center sprocket coaxiality one, motor place spider to prop up grade;

Fig. 2. joint force bike-driven sprocket and center sprocket coaxiality one, motor place spider in front;

Fig. 3. joint force bike-driven sprocket and center sprocket coaxiality one, motor place battery box top;

Fig. 4. what the coaxial heart engagement of joint force bike-driven sprocket and rear wheel sprocket was disposed, motor places after-frame;

Fig. 5. the coaxial heart engagement of joint force bike-driven sprocket and front-wheel central axle sleeve is disposed, motor places front fork, front-wheel is less.

Fig. 6. the coaxial heart engagement of joint force bike-driven sprocket and front-wheel central axle sleeve configuration, motor place front fork, front-wheel is less, vehicle frame is studless.

Fig. 7. battery box and battery.

Embodiment 1 joint force bike as Fig. 1, shown in Figure 7, contains vehicle frame, turns to 14, saddle 3, front-wheel 16, trailing wheel 17, and pedal 19 links via crank and center shaft 18, and center sprocket wheel 5 is incorporated into center shaft 18 and is to join to cooperate through messenger chain 6 and rear wheel sprocket 7; The battery box 8 of device battery 9 through link up with 23,24 and

anchor ear

25,26 hang and be fixed in 20 belows, spider front; Motor 1 is fixed in a shelves 11 of striding connection spider front 20 and back 22, and drive sprocket 2 combines with machine shaft 10 ratchet-types and is to join to cooperate through chain 3 and driven sprocket 4; Driven sprocket 4 and center sprocket wheel 5 coaxial formation one, wherein driven sprocket 4 is positioned at center sprocket wheel 5 outsides, also can be positioned at center sprocket wheel 5 inboards, this two sprocket wheel and the engagement of center shaft ratchet-type.

It is lead-acid battery that this car adopts battery, also can be nickel-cadmium, nickel-Hydrogenized compound, or fuel cell is a kind of, and its energy density of battery is 40wh/kg, and its weight is 2.5kg; Motor is a common DC motor, and its horsepower output is a 1/35-1.5 horsepower, and its rotating speed is 0-1500 rev/min.

When this car drove with manpower, pedal 19 rotated, and center sprocket wheel 5 rotates, and car moves ahead, and is the same with ordinary bicycle; Since drive sprocket 2 and the engagement of machine shaft 10 ratchet-types, at this moment, the rotation in the lump of driven sprocket 4 and drive sprocket 2, motor still keeps not led commentaries on classics;

During driven by power, pedal 19 keeps not rotating, because driven sprocket 4 is ratchet-type engagements together with center sprocket wheel and center shaft 18.

This car can add manpower simultaneously with the motor driven at low speed time, two power drive together, can the each province its half.

Embodiment 2 joint force bikes show that as Fig. 2 motor 1 is fixed in spider front 20, and other structures are identical with last example.

Embodiment 3 Jie Libai driving shows that as Fig. 3, Fig. 7 motor 1 is fixed in the position 27 on battery box top, and other structures are identical with embodiment's 1.

Embodiment 4 joint force bikes show as Fig. 4, and driven sprocket 4 is given prominence to the position with the side that rear wheel sprocket 7 coaxial heart engagements are disposed at this sprocket wheel 7, and this sprocket wheel 7 is different from conventional being, and a side is outstanding; Motor 1 is fixed in after-frame 12, and other structures are identical with embodiment's 1.As the derivation of this example, driven sprocket 4 also can coaxial heart ratchet-type engagement be disposed at the trailing wheel central axle sleeve.

Embodiment 5 joint force bikes show as Fig. 5, driven sprocket 4 and front-wheel central axle sleeve ratchet-type engagement configuration, and before motor 1 is fixed in again 15, front-wheel 16 is less than trailing wheel 17, and other structures are identical with embodiment's 1.

Embodiment 6 joint force bikes, vehicle frame is not established crosspiece, and other structures are identical with embodiment's 5.
