Abstract
The utility model relates to a novel transmission device for a bicycle. The novel transmission device comprises a transmission system, a shaft sleeve and a middle shaft arranged in the shaft sleeve. The novel transmission device is characterized in that the middle shaft is arranged in the shaft sleeve and is connected with the transmission system by a bearing. The transmission system is internally provided with a bearing, a gear, a cylindrical gear, a flywheel pawl, a crank, a gear disc, the shaft sleeve and an end shaft. The novel transmission device is designed by utilizing generated force in an effective manner and eliminating the stress dead angle; and when the novel transmission device is arranged on the bicycle, the effect of a big gear disc can be realized by utilizing a small gear disc, the power generated by a rider can be utilized in the effective manner, so that the motion speed and the climbing capability of the bicycle are improved and the defects of the existing bicycle are overcome.
Description
Technical field
The utility model relates to a kind of driving device, specifically relates to a kind of new bicycle driving device.
Background technology
Common bicycle crank is during soon perpendicular to ground, and this moment, drive torque was little or be zero to cause occurring the dead angle, and then the power that sends of bicyclist can't be brought into play by actv., and is in the middle effort of riding, also very dangerous.
Summary of the invention
The utility model is at above problem, and a kind of environmental protection, low, the practical a kind of new bicycle driving device of cost are provided.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of new bicycle driving device comprises driving system, axle sleeve and is installed in the interior axis of axle sleeve and form that it is characterized in that: be provided with axis in the axle sleeve, axis connects driving system by bearing.
Be provided with bearing, gear, cylindrical wheel, flywheel ratchet, crank, fluted disc, axle sleeve and end axle in the described driving system.
The beneficial effects of the utility model are:
The more efficiently utilization of the utility model is had an effect and stress eliminating dead angle and design-calculated new bicycle driving device, the utility model is installed on the bicycle, can realize utilizing small tooth plate to reach the effect of large fluted disc, the kinetic force that the bicyclist is sent is more effectively utilized, improve the kinematic velocity and the hill climbing ability of bicycle, solve the defective that existing bicycle exists.
So the utility model compared with prior art has reasonable in design, simple in structure, practical characteristics.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the constructional drawing of new bicycle driving device.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of new bicycle driving device as shown in Figure 1, comprises driving system, axle sleeve and is installed in the interior axis of axle sleeve and form that it is characterized in that: be provided with axis in the axle sleeve, axis connects driving system by bearing.
Be provided with bearing, gear, cylindrical wheel, flywheel ratchet, crank, fluted disc, axle sleeve and end axle in the described driving system.
The utility model is to form via the axis of bearing installation in axle sleeve, the bearing, gear, cylindrical wheel, flywheel ratchet, crank, fluted disc, axle sleeve and the end axle that are installed on the axis, utilize the utility model to be installed on the bicycle, to realize utilizing small tooth plate to reach the effect of large fluted disc, eliminated stressed dead angle than common driving device.
In sum, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
