Abstract
The utility model relates to a driving device of a bicycle. The driving device of a bicycle comprising a front axle 7 connected with bicycle pedals in the method of transmission and a back wheel axle 1 used for driving back wheels to rotate is characterized in that a gap bridge axle 4 is arranged between the front axle 7 and the back wheel axle 1, one end of each of the front axle 7 and the gap bridge axle 4 is provided with a pair of bevel gears 6 and 5 which are engaged and driven mutually, and the other end of each of the back wheel axle 1 and the gap bridge axle 4 is provided with a pair of bevel gears 2 and 3 which are engaged and driven mutually. Bicycles have the advantages of flexible transmission, compact structure and long service life via the utility model, and labor is saved more than 1 / 4 as compared with the bicycles using chainwheels and chain for transmission.
Description
The utility model relates to a kind of driving device of vehicle, relates in particular to a kind of driving device of bicycle.
The type of drive of bicycle is the sprocket wheel chain gear of adopting at present, is by rotating the sprocket rotation on the step drive front axle, being rotated through the flywheel that chain drives on the hind axle by sprocket wheel, to drive cycle racing.Adopt this type of drive that chain fracture or rust are rotted, need often to repair or change chain, bring inconvenience to the user.And adopting the sprocket wheel chain gear that the people is required great effort by bike, the vehicle body deal is heavy again.
The purpose of this utility model is for providing the bicycle drive of a kind of ensuring smooth transmission, light and handy, long service life.
The utility model is achieved in that a kind of bicycle drive, comprise the front axle that is in transmission connection with the bicycle step and drive the hind axle that trailing wheel rotates, be characterized in being provided with between front axle and hind axle a gap bridge axle, the finishing bevel gear cuter of a pair of transmission that is meshing with each other is arranged with an end device of the axle of passing a bridge on the described front axle; The other end of one end of described hind axle and the axle of passing a bridge is provided with the finishing bevel gear cuter of a pair of transmission that is meshing with each other.
Compare with existing bicycle chainwheel chain transmission mode, the utility model is owing to adopted gear-driven mode, make bicycle ensuring smooth transmission, light and handy, compact conformation, bicycle normal off chain and the mashed phenomenon of rust have been changed, improved the service life of driving device, also alleviated tare, and more laborsaving more than 1/4 than using the sprocket wheel chain gear.
Fig. 1 is an overall structure scheme drawing of the present utility model.
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
As shown in Figure 1, the utility model is at front axle 7 former bicycle and that step is in transmission connection and 1 of hind axle driving the trailing wheel transmission axle 4 of passing a bridge to be set, the transmission that is meshing with each other of device one finishing bevel gear cuter 6 on the described front axle 7, an end device one finishing bevel gear cuter 5 of the axle 4 of passing a bridge, finishing bevel gear cuter 6 and finishing bevel gear cuter 5; One end of described hind axle 1 is provided with a finishing bevel gear cuter 2, and the other end of the axle 4 of passing a bridge is provided with a finishing bevel gear cuter 3, the transmission that is meshing with each other of finishing bevel gear cuter 3 and finishing bevel gear cuter 2.During work, rotate step and drive front axle 7 rotations, driving finishing bevel gear cuter mounted thereto 6 by front axle 7 rotates, finishing bevel gear cuter 6 drives the axle 4 of passing a bridge by finishing bevel gear cuter 5 engaged transmission and rotates, and drive finishing bevel gear cuter 2 by pass a bridge axle 4 and finishing bevel gear cuter 3 by engaged transmission and rotate, drive trailing wheel by finishing bevel gear cuter 2 through hind axle 1 at last and rotate, bicycle is moved forward.
Claims (1)
