Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Referring to Fig. 2, in the embodiment of the present invention, a kind of improved bicycle drive shaft, including main shaft 1, right side bearing 2, left side bearing 3, housing 4 and card based shell 5.The two ends of main shaft 1 are arranged on vehicle frame 10, main shaft 1 is arranged in housing 4, right side bearing 2 and left side bearing 3 are provided between the two ends of main shaft 1 and housing 4, so that housing 4 can rotate around the axial line of main shaft 1, right side bearing 2 and left side bearing 3 play and undertake all loads.Side lid 7 is respectively equipped between right side bearing 2 and left side bearing 3 and vehicle frame 10, side lid 7 plays a part of axially position and protection to this two bearings.Card based shell 5 is arranged on one end of housing 4, and its outer surface is used for Flywheel device, bearing arrangement 6 is provided between card based shell 5 and housing 4（The bearing arrangement can be plain bearing arrangement, or rolling bearing system）, so that card based shell 5 rotates around the axial line of housing 4, that is to say, that card machine housing 5 is also the axial line rotation along main shaft 1；Stop nut 8 is located at the outside of card based shell 5, and threaded connection is acted on the axially position with one end of housing 4, playing to card based shell 4.Ratchet device 9 is provided between card based shell 5 and housing 4, its effect is that the torsion that flywheel is transmitted into card based shell 5 is delivered to housing 4.
Please refer to Fig. 1 and Fig. 2, right side bearing 2 in common hub structure is close to the centre position of main shaft 1, it is evident that, so cause the easy deformation that bends when being loaded of main shaft 1, and because right side bearing 2 is close to the center line stress point of flower-drum, and the principle center line stress point of left side bearing 3, so that right side bearing 2 bears most load, so being also easily damaged.And the innovative point of the present invention is that right side bearing 2 is located at into the right side of main shaft 1 close to the position of vehicle frame, it is evident that, so main shaft 1 is when being loaded, bending moment suffered by it is significantly less than the bending moment suffered by main shaft 1 in traditional flower-drum, therefore the more difficult deformation that bends of main shaft 1, so that the integral rigidity of wheel group is significantly lifted, improve quality of riding, and because right side bearing 2 and left side bearing 3 are respectively further from center line stress point, so as to make this two bearings undertake load in a balanced way jointly, so as to greatly improve the durability of bearing.
And from another viewpoint, Fig. 1, Fig. 2 and Fig. 3 are please referred to, in common hub structure, card based shell 5 is by the installation of bearing arrangement 6 and main shaft 1, in this case, in trampling for heavier loads（Process steps on foot-operated 14 band movable sprocket 13, sprocket wheel 13 for bicyclist and drives chain 12, the flywheel driven 11 of chain 12, flywheel 11 to drive card based shell 5, card based shell 5 to pass through the drive housing 4 of ratchet device 9）In the stage, there is relative rotary motion between card based shell 5 and main shaft 1, therefore bearing arrangement 6 is the operating pressure that carry elevated pressures.And the card based shell 5 in the hub structure of the present invention is to be installed by bearing arrangement 6 with housing 4, being totally independent of outside main shaft 1, in this case, in trampling for heavier loads（Process steps on foot-operated 14 band movable sprocket 13, sprocket wheel 13 for bicyclist and drives chain 12, the flywheel driven 11 of chain 12, flywheel 11 to drive card based shell 5, card based shell 5 to pass through the drive housing 4 of ratchet device 9）Stage, card based shell 5 and housing 4 are synchronous rotaries, that is now the interior outside of bearing arrangement 6 in synchronous rotary state, this means now bearing, only by static pressure, relative rotary motion do not occur for interior outside, therefore the operating pressure of bearing arrangement 6 is significantly lower than the operating pressure of the bearing arrangement 6 in common hub structure.So being compared with common hub structure, the operating pressure of bearing arrangement 6 is reduced, the durability of flower-drum is improved.
