Abstract
A dual-driver bicycle with wheel-varying mechanism features that it has similar two drive systems, that is, front one driven by hands and back one driven by feet, and two small wheels able to be suspended are additionally attached to its back wheel axle.
Description
Affiliated technical field:
The present invention relates to a kind of bicycle front fork band chain wheel and chain wheel driving device, especially be provided with a cover about trailing wheel and become the wheel safety system, the double-driven and wheel-variable bicycle that the while liftable lands.
Background technology:
At present, the bicycle front-wheel is a steering wheel, and trailing wheel is a drive wheel; Front-wheel is existed all the time by dynamic resistance, and front and back wheel does not have safety traffic to support, and this makes that the bicycle of low speed, heavy burden is not only movable among a small circle, and the incident of toppling over can take place at any time.
Summary of the invention:
In order to overcome the defective of said structure, the invention provides a kind of double-driven and wheel-variable bicycle, this double-driven and wheel-variable bicycle can not only be used both hands and feet at any time, front and back wheel drives, average velociity significantly improves and do not influence the basic function flexibly of turning, and whenever can make two-wheeled become four-wheel safety to land.
This practicality invention solves the technical scheme that its technical matters adopted: the driving device that is provided with and has (single or) double teeth wheel and rocking handle above bicycle front fork, driving device joins respectively by chain and the front wheel spindle upper sprocket wheel right side (or left side) side, and the movable post of driving device and handlebar front fork top joins; The scheme that becomes the wheel safety system is: a movable mounting on the back wheels of vehicle axle is set, and respectively there is a steamboat both sides, mounting bottom, the anterior and seat rear portion socket of mounting, and steamboat can hang simultaneously during deadhead operation.
The invention has the beneficial effects as follows: fully liberate both hands, change single fatigue, significantly improve speed, structural safety is flexible.
Description of drawings:
Fig. 1 is a front view of the present invention
Fig. 2 is a birds-eye view of the present invention
Fig. 3 is a change wheel safety system scheme drawing of the present invention
The movable post 6 of 1 driving device, 2 chains, 3 fronts wheel spindle, 4 sprocket wheels, 5 front forks becomes the wheel safety system among the figure
The specific embodiment
In the drawings, driving device 1 joins respectively by chain 2 and front wheel spindle 3 sprocket wheels 4 both sides; Driving device 1 joins with the movable post 5 of front fork, becomes wheel safety system 6 and both can make mounting and station frame, the safety supports in the time of can travelling again and than heavy.
Claims (1)
