Abstract
The utility model discloses a driving gear of a bicycle, which comprises a driving wheel, a driven wheel, a central shaft, a crank, and pedals, wherein the driving wheel is fixed onto the central shaft; the driven wheel is arranged on the central shaft in series; the driving wheel is positioned in the driven wheel; the driving wheel and the driven wheel can form a ratchet wheel structure; the driven wheel and the central shaft are connected through a bearing, and the central shaft is connected with the pedals through the crank. Compared with the traditional technology, the utility model which omits inconvenience brought by drive of a chain has the advantages of simpler structure, convenient device maintenance and convenient maintenance.
Description
Technical field
The utility model relates to a kind of bicycle driving device.
Background technology
Existing bicycle driving device is to be connected with the flywheel of trailing wheel by chain by sprocket wheel, thereby realizes that bicycle drives; by this type of transmission of chain, because the existence of chain chain usually can occur and fall down from flywheel; the situation that chain fractures, this just causes very big inconvenience to the user, and; existing bicycle; the rider rides seat at the middle part of car, and people's body erect is in process by bike; resistance ratios is bigger, relatively effort.
The utility model content
At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of simple in structure, bicycle driving device that result of use is good.
The technical solution adopted in the utility model is: a kind of bicycle driving device, comprise drive wheel, flower wheel, center shaft, crank, pedal, described drive wheel is fixed on the center shaft, the flower wheel string is located on the center shaft, described drive wheel is positioned at flower wheel, drive wheel and flower wheel constitute ratchet structure, are connected by bearing between described flower wheel and the center shaft, and described center shaft is connected with pedal by crank.
The described flower wheel outside can also be provided with brake disc, and described brake disc string is located on the described center shaft, and is connected with fixed center axis by bearing.
Between the crank of described center shaft and drive wheel, can be connected to bike support by movable sleeve.
This bicycle driving device of the present utility model, by the ratchet structure between drive wheel and the flower wheel, be connected by bearing between flower wheel and the center shaft, described center shaft is connected with pedal by crank, thereby realizes bicycle driving, compares with conventional art, structure is simpler, save the inconvenience that drive brought of chain, equipment repair is convenient, is convenient to maintenance.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model.
The specific embodiment
Shown in Fig. 1-2, bicycle driving device of the present utility model, comprise drive wheel 1, flower wheel 2, center shaft 3, crank 4, pedal 5, drive wheel 1 is fixed on the center shaft 3, flower wheel 2 strings are located on the center shaft 3, and drive wheel 1 is positioned at flower wheel 2, and drive wheel 2 constitutes ratchet structure with flower wheel 1, be connected by bearing 7 between flower wheel 2 and the center shaft 3, center shaft 3 is connected with pedal 5 by crank 4.
On actuating device, brake equipment can be installed, shown in Fig. 1-2, brake disc 8 be arranged in flower wheel 2 arranged outside, brake disc 8 strings are located on the center shaft 3, and be connected with center shaft 3 by bearing 9, bearing 9 carries brake disc 8 and vehicle frame simultaneously, and brake disc 8 can be realized the braking to bicycle.Among the figure 10 is steel bead groove, and 11 among the figure is for connecting the bearing of center shaft 3 and vehicle frame.
Between the crank 4 of center shaft 3 and drive wheel 1, can be connected to bike support by movable sleeve, make things convenient for bicycle parking.
