Abstract
The present utility model discloses a unilateral driver having simple structure, long service life and being able to use on the equipments such as the bicycle, whose structure primarily includes driving gear and driven gear that is installed inside the driving gear. The utility model is characterized in that outer side of the driving gear is equipped with transmission double-wedge, the inner side of the driving gear is provided with unilateral transmission tooth; outer side of the driven gear is equipped with socket base which is provided with flexible driving rod whose outer side could touch the unilateral driving tooth.
Description
Technical field
The utility model relates to a kind of unidirectional driver that can be used on the equipment such as manpower bicycle, electric bicycle, pedicab.
Background technique
On equipment such as manpower bicycle, electric bicycle, pedicab, all be provided with unidirectional driver usually---be commonly called as by " flywheel ", be used to guarantee the normal operation of these equipment.Unidirectional driver generally all is installed on the rear-wheel spindle of these equipment, and the outside and sprocket wheel are fixed, by chain by sprocket wheel, and unidirectional driver drive rear-wheel spindle and rotate, and then drive trailing wheel and rotate.The structure of traditional unidirectional driver is complicated, need often refuel and safeguard that very bother, working life is not long yet.
Summary of the invention
At the problems referred to above, the utility model will provide a kind of unidirectional driver simple in structure, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: described unidirectional driver, mainly comprise: driving wheel, driven wheel is sleeved in the driving wheel, be characterized in: the arranged outside at driving wheel has the transmission double wedge, is provided with unidirectional driving cog in the inboard of driving wheel, in the arranged outside of driven wheel the nest seat is arranged, flexible driving rod is movably arranged in the nest seat, and the outer end of flexible driving rod can contact with unidirectional driving cog.
The further technological scheme of the utility model is: a kind of structure of described flexible driving rod is: the spheric end of flexible driving rod is movably arranged in the spherical groove in the nest seat, is provided with elastic component between flexible driving rod and driven wheel.
The utility model further technological scheme is: described elastic component is an elastic wire, and an end of elastic wire is arranged on the spheric end of flexible driving rod, and the other end of elastic wire contacts with driven wheel.The utility model has the advantages that: simple in structure, easy to use, working life is longer.
Description of drawings
Fig. 1 is the structural principle schematic representation of unidirectional driver described in the utility model.
Mode of execution
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, in the present embodiment, described unidirectional driver comprises: driving wheel 5, driven wheel 1 is sleeved in the driving wheel 5, arranged outside at driving wheel 5 has transmission double wedge 6, be provided with unidirectional driving cog 7 in the inboard of driving wheel 5, arranged outside at driven wheel 1 has nest seat 2, the spheric end of flexible driving rod 4 is movably arranged in the spherical groove in the nest seat 2, between flexible driving rod 4 and driven wheel 1, be provided with elastic component---elastic wire 3, an end of elastic wire 3 is arranged on the spheric end of flexible driving rod 4, and the other end contacts with driven wheel 1, under the effect of elastic wire 3, the outer end of flexible driving rod 4 can contact with unidirectional driving cog 7.In actual fabrication, the quantity of unidirectional driving cog 7 and flexible driving rod 4 can come to determine as required.
The using method of the unidirectional driver of said structure is: when supposing to use on manpower bicycle, driven wheel 1 can be installed on the rear-wheel spindle of bicycle, the transmission double wedge 6 in driving wheel 5 outsides is connected with using the synchronous belt in bicycle; Its using method is identical with the using method of the traditional unidirectional driver described in the background technique, that is: the synchronous belt in the bicycle at first drives driving wheel 5 rotations to a certain direction---be assumed to be the clockwise direction rotation shown in Fig. 1, driving wheel 5 drives and then rotation of driven wheel 1 by the unidirectional driving cog 7 and the flexible driving rod 4 of its inboard, driven wheel 1 drives rear-wheel spindle again and rotates, and then driving and then rotation of trailing wheel, final realization drives whole the purpose that bicycle advances.In normal course of operation, slack or fall back when driving wheel 5---promptly: when the counter clockwise direction shown in Fig. 1 is rotated, at this moment, owing to do not play gearing between the unidirectional driving cog 7 of driving wheel 5 inboards and the flexible driving rod 4, thereby can not hinder the rotary state of driven wheel 1.
Claims (3)
1, unidirectional driver, mainly comprise: driving wheel, driven wheel is sleeved in the driving wheel, it is characterized in that: the arranged outside at driving wheel has the transmission double wedge, be provided with unidirectional driving cog in the inboard of driving wheel, arranged outside at driven wheel has the nest seat, and flexible driving rod is movably arranged in the nest seat, and the outer end of flexible driving rod can contact with unidirectional driving cog.
2, unidirectional driver as claimed in claim 1, it is characterized in that: a kind of structural type of described flexible driving rod is: the spheric end of flexible driving rod is movably arranged in the spherical groove in the nest seat, is provided with elastic component between flexible driving rod and driven wheel.
