Abstract
The utility model relate to a variable-speed bicycle capable of being ridden backwards. A driving chain wheel and a bicycle rear flywheel of the bicycle are composed of a small driving chain wheel, a forward mounted bicycle rear flywheel, a large driving chain wheel and a reversely mounted bicycle rear flywheel which are mutually matched. Two handles of the bicycle are respectively provided with a driving chain wheel selector and a rear flywheel selector. A driving chain wheel transmission screw extended out of the driving chain wheel selector is attached to a bicycle body to be connected with a front derailleur arranged on the small driving chain wheel and the large driving chain wheel. A rear flywheel transmission screw extended out of the bicycle rear flywheel selector is attached to the bicycle body to be connected with a rear derailleur arranged on the forward mounted bicycle rear flywheel and the reversely mounted bicycle rear flywheel. The bicycle can not only be ridden forward and speed-changed normally, but also be ridden backwards. Under emergent conditions, the bicycle can be shifted to the reversely mounted bicycle rear flywheel and play the function of emergent braking, accordingly using value of the bicycle is fully developed, and practical applicability of the bicycle is added.
Description
Technical field
The utility model relates to a kind of variable speed bicycle, specifically a kind of variable speed bicycle of riding backwards.
Background technology
Existing bicycle has many types.Have the single freewheel bicycle that variable speed bicycle is also arranged, but these bicycles all just can be to overtake, and be fit to ordinary consumer the bicycle of riding backwards, when emergency case such as brake failure occurring, do not have the solution of economical rationality yet.The function of bicycle is limited at present, and fully exploitation does not have reasonable manner to solve this problem in fact with being worth at present.
Summary of the invention
In order to solve the problem that bicycle in use runs into, the utility model provides a kind of variable speed bicycle of riding backwards, this bicycle has fully been developed the value of service of car, makes the function of bicycle be expanded.
The utility model solves the technical scheme that its technical matters adopted: a kind of variable speed bicycle of riding backwards comprises back group device, formal dress bicycle rear flywheel, anti-bicycle rear flywheel, active minor sprocket, active hinge wheel, preceding group of device, rear flywheel driving wire, drive sprocket driving wire, drive sprocket selector and rear flywheel selector adorned; It is characterized in that: the drive sprocket of the variable speed bicycle that this can be ridden backwards and bicycle rear flywheel are that the active minor sprocket, formal dress bicycle rear flywheel, active hinge wheel, the anti-bicycle rear flywheel of adorning that cooperatively interact are formed; Two grip of this bicycle device respectively have drive sprocket selector and rear flywheel selector; The drive sprocket driving wire that the drive sprocket selector stretches out is pasting car body and is being connected to preceding group of device on active minor sprocket and the active hinge wheel, and the rear flywheel driving wire that bicycle rear flywheel selector stretches out is pasting car body and is being connected to formal dress bicycle rear flywheel and the anti-back group of device of adorning on the bicycle rear flywheel; During use, the bicycle forward travel when needing speed change, is regulated the drive sprocket selector, and power through the drive sprocket driving wire, is dialled device before passing to, and makes chain change to initiatively hinge wheel from the active minor sprocket, realizes speed change thereby change transmitting ratio.When needs change reverse gear, regulate the rear flywheel selector, power is passed to the back through the rear flywheel driving wire dials device, make chain from formal dress bicycle rear flywheel to anti-dress bicycle rear flywheel, thereby can realize riding backwards.
The beneficial effect of the utility model is: this variable speed bicycle that can ride backwards not only can be normally to overtake, speed change; And can realize riding backwards; In case of emergency transform to anti-dress bicycle rear flywheel and can play the value of service that bicycle has fully been developed in the emergency brake effect, increase its practicality.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the example structure scheme drawing of this variable speed bicycle that can ride backwards.
Among the figure, 1, the back dials device, 2, formal dress bicycle rear flywheel, 3, the anti-bicycle rear flywheel of adorning; 4, minor sprocket initiatively, 5, hinge wheel initiatively, 6, preceding group of device, 7, the rear flywheel driving wire; 8, drive sprocket driving wire, 9, the drive sprocket selector, 10, the rear flywheel selector.
The specific embodiment
In the drawings; A kind of variable speed bicycle of riding backwards comprises back group device 1, formal dress bicycle rear flywheel 2, anti-bicycle rear flywheel 3, active minor sprocket 4, active hinge wheel 5, preceding group of device 6, rear flywheel driving wire 7, drive sprocket driving wire 8, drive sprocket selector 9 and rear flywheel selector 10 adorned; The drive sprocket of the variable speed bicycle that this can be ridden backwards and bicycle rear flywheel are that the active minor sprocket 4, formal dress bicycle rear flywheel 2, active hinge wheel 5, the anti-bicycle rear flywheel 3 of adorning that cooperatively interact are formed; Two grip of this bicycle device respectively have drive sprocket selector 9 and rear flywheel selector 10; The drive sprocket driving wire 8 that drive sprocket selector 9 stretches out is pasting car body and is being connected to preceding group of device 6 on active minor sprocket 4 and the active hinge wheel 5, and the rear flywheel driving wire 7 that bicycle rear flywheel selector 10 stretches out is pasting car body and is being connected to formal dress bicycle rear flywheel 2 and the anti-back group of device of adorning on the bicycle rear flywheel 31; During use, the bicycle forward travel when needing speed change, is regulated drive sprocket selector 9, and power through drive sprocket driving wire 8, is dialled device 6 before passing to, and makes chain change to initiatively hinge wheel 5 from active minor sprocket 4, realizes speed change thereby change transmitting ratio.When needs change reverse gear, regulate rear flywheel selector 10, power is passed to the back through rear flywheel driving wire 7 dials device 1, make chain from formal dress bicycle rear flywheel 2 to anti-dress bicycle rear flywheel 3, thereby can realize riding backwards.
