Description
Technical field
The present invention relates to technical field of bicycles, especially relate to a kind of automatic shift device.
Background technology
The effect of bicycle shift system is exactly that the cooperation of toothed disc by changing chain and different forward and backward sizes changes speed of a motor vehicle speed.The size of nipper wheel disc and the size of backgear dish determine dynamics during bicycle turn pedal.Nipper wheel disc is larger, and backgear dish more hour, more feels effort during pedal.Nipper wheel disc is less, when backgear dish is larger, more feels relief during pedal.According to the ability of different driver, namely by the speed of a motor vehicle of the size adjustment bicycle of adjustment front and rear teeth wheel disc, or tackle different sections, road conditions.
Fig. 1 is the structural representation of existing transmission system; Shown in Figure 1, existing bicycle, the gear shift mode of its transmission system is manual toggle gear change hand lever 1 ', and then the length changing bracing wire 2 ' changes derailleur 3 ' angle, and then change the position of chain 4 ' on toothed disc 5 ', namely relative to bicycle rear direction by chain 4 ' on toothed disc 5 ' inwards or to extrapolation, to adjust the transmitting ratio between nipper wheel disc and backgear dish that stretcher drives; Described toothed disc 5 ' is multi-disc cluster gear dish.
Existing transmission system have following shortcoming:
First, usually rule of thumb speed change is carried out by bicyclist, untrained bicyclist lacks reasonableness to the selection of speed change gear, and to comprising front chain shifter, the interaction force of derailleur of rear derailleur do not understand, and easily causes and tramples inefficiency, transmission system damages and injury gained in sports;
The second, irregular to cause transmission system to regulate loaded down with trivial details for the mass discrepancy of gear change hand lever, bracing wire, derailleur and the experimental technology of technical personnel, and is difficult to adjust to optimum regime, easily causes that chain and toothed disc wearing and tearing are accelerated, shift has some setbacks and the fault such as trip stop;
Three, the gear change hand lever between different brands, different gear and derailleur cannot be compatible, cause upgrade cost high; The gear change hand lever of such as 8 grades cannot with the derailleur collaborative work of 9 grades; Replacing sheet number more cluster gear dish must change corresponding gear change hand lever simultaneously and derailleur just can reach the upgrading object increasing gear.
To sum up, the speed change of existing transmission system relies on technology and the experience of personnel, easily causes problems such as trampling inefficiency, transmission system damage and personnel's injury gained in sports.
Therefore, be badly in need of providing a kind of new automatic shift device for the problems referred to above, make the speed of a motor vehicle automatic speed changing of bicycle to optimum regime.
