Abstract
The utility model relates to a front-rear-wheel double-driven bicycle which is composed of a frame, a front and a rear wheels, a centre shaft and a drive mechanism. The utility model is characterized in that a front wheel drive mechanism is also arranged on a position handle of the front wheel. The drive mechanism (4) is provided with a lower chain wheel (5), a middle chain wheel (6) and a handle chain wheel (7). The lower chain wheel (5) is coaxial with the front wheel, the middle chain wheel (6) is a child-mother coaxial wheel and is arranged at the position of a front fork, and the handle chain wheel (7) is arranged at the cross beam part of a front handle and is driven by a chain (8) and a chain (9). The utility model has the advantages of simple structure and convenient manufacture. Besides, the arrangement of the double-driven mechanism by the front wheel and the rear wheel can cause a rider to use the hands and the feet simultaneously when the rider rides, a person with strong arm strength can fully play the action and a person with weak leg strength uses the arm strength to assist the power. The utility model is an ideal front-rear-wheel double-driven bicycle.
Description
One, technical field:
The utility model relates to a kind of bicycle, particularly a kind of front and back wheel double driving bicycle.
Two, background technology:
Present bicycle mostly is single driving bicycle, thereby is thinking the comparison difficulty of using both hands and feet when firmly quickening that the big person of arm strength is played one's part to the full, and this is the deficiency of existing bicycle.
Three, summary of the invention:
The purpose of this utility model is a kind of front and back wheel double driving bicycle of invention, and this bicycle is provided with two driver trains that drive of front-wheel and trailing wheel, can use both hands and feet, and the big person of arm strength is played one's part to the full, in order to overcome the deficiency of existing bicycle.
The purpose of this utility model can realize by following embodiment: this bicycle, form by vehicle frame front and back wheel and axis driver train, it is characterized in that on the handle of the position of front-wheel, also being provided with driver train, driver train has lower sprocket, middle sprocket and sprocket wheel, and lower sprocket and front-wheel are coaxial, middle sprocket is the primary and secondary coaxial wheels, be located at front fork part, the header portion of handle before sprocket wheel is located at, its transmission is by two chain gears.
By middle transverse axis, the transverse axis cover, the assurance of establishing on the wheel cover of sprocket wheel, the middle transverse axis and two are turned formation before the utility model, the transverse axis cover is connected with the wheel cover, and two are turned the two that is located at middle transverse axis.
The utility model has flat hole at the position that wheel overlaps by chain.
The utility model driver train also can be provided with on tricycle, and corresponding tricycle constitutes two three-wheel self-moving vehicles that drive.
Advantage of the present utility model is simple in structure, easily manufactured, and the double driving mechanism that is provided with front-wheel and trailing wheel can be used both hands and feet when riding, and the big person of arm strength is played one's part to the full, and makes the little person of leg strength use the arm strength power-assisted, is a kind of desirable front and back wheel double driving bicycle.
Four, description of drawings:
Fig. 1 is the utility model unitary construction scheme drawing.
Fig. 2 is preceding partial schematic sectional view.
Five, the specific embodiment:
As shown in Figure 1, 2, this bicycle, be made up of vehicle frame 1 front and back wheel 2 and axis driver train 3, it is characterized in that also being provided with driver train 4 on the handle of the position of front-wheel, driver train 4 has lower sprocket 5, middle sprocket 6 and sprocket wheel 7, lower sprocket 5 and front-wheel are coaxial, and middle sprocket 6 is the primary and secondary coaxial wheels, is located at front fork part, before sprocket wheel 7 is located at header portion, its transmission is by chain 8 and chain 9 transmissions.
By middle transverse axis 10, transverse axis cover 11, the assurance 13 of establishing on the wheel of sprocket wheel 7 cover 12, the middle transverse axis 10 and two are turned 14 constitute before the utility model, transverse axis cover 11 is connected with wheel cover 12, and two are turned 14 two that are located at middle transverse axis 10.
The utility model has inclined to one side hole in wheel cover 12 societies of portion by chain 8.
The utility model driver train 4 also can be provided with on tricycle, and corresponding tricycle constitutes two three-wheel self-moving vehicles that drive.
