Abstract
The utility model relates to a pedal power assistant increasing speed vehicle, which is characterized in that a group of increasing speed sprockets which are an increasing speed small sprocket and an increasing speed big sprocket are provided between a pedal sprocket and a dynamic wheel sprocket, the increasing speed small sprocket and the increasing speed big sprocket are coaxially conjoined sprockets, the pedal sprocket and the increasing speed small sprocket are transmitted through a chain, and the increasing speed big sprocket and the dynamic wheel sprocket are transmitted through the chain. The utility model has the advantages that the structure is simple, the running speed is capable of being exponentially improved, the running speed of the utility model is 2.4 times to 4 times more than a prior vehicle, and the speed per hour can reach above 100 kilometers. The utility model is suitable for a bicycle, a tricycle and a pedal racing bicycle.
Description
The utility model relates to a kind of foot-operated, power-assisted speedup car, is applicable to bicycle, three-wheel vehicle, foot-operated racing car etc.
At present, bicycle and its Power train of three-wheel vehicle commonly used are made up of foot-operated sprocket wheel, chain, dynamic wheel sprocket wheel, and its shortcoming is that road speed is lower.And the transmission device of derailleur is complicated, and is also inconvenient when changing the speed of a motor vehicle.
The purpose of this utility model provides a kind of simple in structure, foot-operated, power-assisted speedup car that can significantly improve road speed.
The purpose of this utility model is achieved in that a kind of foot-operated, power-assisted speedup car, its constructional feature is to be provided with one group of speedup sprocket wheel between foot-operated sprocket wheel and dynamic wheel sprocket wheel, be speedup minor sprocket and speedup hinge wheel, the speedup minor sprocket is coaxial conjuncted sprocket wheel with the speedup hinge wheel, foot-operated sprocket wheel and speedup minor sprocket are by chain gear, and speedup hinge wheel and dynamic wheel sprocket wheel are by chain gear.
Speedup minor sprocket and speedup hinge wheel are positioned at the both sides of vehicle frame or are positioned at the same side of vehicle frame.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
By the embodiment shown in Fig. 1,2 as can be known, it is a foot-operated speeding-up bike, its constructional feature is to be provided with one group of speedup sprocket wheel between foot-operated sprocket wheel 1 and dynamic wheel sprocket wheel 4, be speedup minor sprocket 2 and speedup hinge wheel 3, the equal diameters of the diameter of speedup hinge wheel 3 and foot-operated sprocket wheel 1, the equal diameters of the diameter of speedup minor sprocket 2 and dynamic wheel sprocket wheel 4.Speedup minor sprocket 2 is coaxial conjuncted sprocket wheel with speedup hinge wheel 3, and foot-operated sprocket wheel 1 and speedup minor sprocket 2 are by chain 6 transmissions and be positioned at a side of vehicle frame, and speedup hinge wheel 3 and dynamic wheel sprocket wheel 4 are by chain 7 transmissions and be positioned at the opposite side of vehicle frame.(speedup minor sprocket 2 and speedup hinge wheel 3 also can be positioned at the same side of vehicle frame.)
In Fig. 1,2,5 is dynamic wheel.
Below by calculating speedup car speedup principle is described further:
1, speedup car and existing type garage vehicle speed formula:
(1) the vehicle speed V1=of speedup garage (n π D1D3D5)/(D2D4)
(2) the existing vehicle speed V2=of type garage (n π D1D5)/D4
N in the formula: the revolution of foot-operated sprocket wheel 1, D1: the diameter of foot-operated sprocket wheel 1, D2: the diameter of speedup minor sprocket 2, D3: the diameter of speedup hinge wheel 3, D4: the diameter of dynamic wheel sprocket wheel 4, D5: the diameter of dynamic wheel 5.
2, be example with 26 inch bicycles, ride sprocket wheel 1 and press per second 1 week calculating that speedup car and existing type car per hour road speed compare:
(1) per hour road speed is as follows for the speedup car:
A, if D1=D3=200mm, D2=D4=70mm, D5=650mm, then V1=60.01 kilometer/hour;
B, if D1=D3=200mm, D2=D4=50mm, D5=650mm, then V1=117.62 kilometer/hour;
C, if D1=D3=120mm, D2=D4=50mm, D5=650mm, then V1=42.34 kilometer/hour.
(2) per hour road speed is as follows for existing type car:
A, if D1=200mm, D4=70mm, D5=650mm, then V2=21 kilometer/hour;
B, if D1=200mm, D4=50mm, D5=650mm, then V2=29.41 kilometer/hour;
C, if D1=120mm, D4=50mm, D5=650mm, then V2=17.64 kilometer/hour.
3, speedup car road speed and the existing type car ratio of road speed (for the multiple of speed of a motor vehicle increase) per hour per hour:
A, V1/V2=60.01/21=2.857 times,
B, V1/V2=117.62/29.41=4 times,
C, V1/V2=42.34/17.64=2.4 are doubly.
4, increase revolution n, strengthen the numerical value of D1, D3, D5, or reduce the numerical value of D2, D4, the speed of a motor vehicle will strengthen.Mix driving engine or electric boosted, just can reach not only laborsaving but also high-revolving driving.Add light-duty transparent dihedral (before the steering handle) checking plate, the resistance of wind in the time of can reducing to run at high speed.Make racing car and can rewrite the competition field record.
The utility model has the advantages that simple in structurely, can greatly improve road speed, the driving of speed increasing vehicle Speed goes out 24-4 doubly than existing type overall height, and speed per hour can reach more than hundred kilometers. It not only is applicable to bicycle, Also be applicable to tricycle and foot-operated racing car.
