Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Front-wheel 13 assembly of a kind of side direction fit type as shown in Figure 1 to 9, comprise kinematic link 10 and front-wheel 13, front-wheel 13 is rotationally connected with one end of kinematic link 10 by axle assembly, kinematic link 10 be parallel to front-wheel 13 rotational plane and not in the rotational plane of front-wheel 13.
Front component 1 in the present embodiment effectively can reduce the folding volume of bicycle, makes front-wheel 13 stacking with trailing wheel and is in parallel plane, and reduce front-wheel 13 to greatest extent on the impact of trailing wheel when folding, it is folding more reasonable to make.
In front component 1, kinematic link 10 is parallel to the rotational plane of front-wheel 13 and not in the rotational plane of front-wheel 13, namely kinematic link 10 is positioned at the side of front-wheel 13, front-wheel 13 can be made to turn to the opposite side of kinematic link 10 by rotating kinematic link 10.
By also having headstock to coordinate the vehicle frame of the front component 1 in the utility model and folding bicycle and trailing wheel, the volume after folding of bicycle can be made to be reduced to minimum.
