Abstract
The utility model discloses a kind of bicycle drive and with the device bicycle and electric bicycle, the transmission device includes Five-way tube and rear chain stay, transmission input shaft is provided in Five-way tube, the transmission output shaft that conical gear is connected with transmission input shaft is provided in rear chain stay；The both ends of transmission input shaft are fixedly connected respectively by spring bearing with being correspondingly arranged at the Five-way tube lid of Five-way tube both sides, and the both ends of transmission input shaft are fixedly connected respectively with bicycle pedal；Transmission output shaft is fixedly connected respectively by the thrust ball bearing and needle bearing that are arranged with the output shaft bearing mounting base being arranged between the Five-way tube and rear chain stay.Traditional deep groove ball bearing is replaced using thrust ball bearing and needle bearing in the utility model, since the axial load of thrust ball bearing is big, the radial load bigger of needle bearing, and the volume smaller of needle bearing, so that the overall structure of transmission device is compacter, volume smaller, service life are longer.
Description
Technical field
The utility model is related to a kind of bicycle drive and with the device bicycle and electric bicycle, belong to
Bicycle transmission technical field.
Background technology
The transmission device of existing bicycle and electric bicycle is chain driving, for example carries rear-guard wheel hub motor
Electric bicycle, pass through chain (and sprocket wheel) between axis and rear-guard wheel hub motor and be sequentially connected, the connection of the both ends of axis
Crank, crank end connection are foot-operated.In practical application, under electric model, rear-guard wheel hub electrical power runs and directly drives
Rear wheel makes vehicle forward；Under manpower ride mode, bicyclist tramples foot-operated, and passes through crank handle turns middle shaft rotation, axis
It is rotated by the shell of chain-driving wheel hub motor, motor housing drives bicycle rear rotation and makes vehicle forward.
Above-mentioned this chain driving device has the following disadvantages：Driving chain easy fracture damages, and easily accidental injury makes
User, while user's clothing is easily stained, and need often to safeguard.Therefore, axis transmission has been used to replace in recent years general
Logical chain drive, axis transmission have the characteristics that the both ends of the drive shaft of solid firm non-maintaining but traditional axis transmission generally makes
With deep groove ball bearing, and deep groove ball bearing diameter and height be than big, increases the dimension and weight of vehicle frame, and deep groove ball bearing
It is axial less than normal with radial load, influence very much the service life of transmission system.
Utility model content
The utility model aim is to provide a kind of bicycle drive in view of the defects existing in the prior art and have to be somebody's turn to do
The bicycle and electric bicycle of device.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of bicycle drive is logical including five
Pipe and rear chain stay, are provided with transmission input shaft in the Five-way tube, be provided in chain stay after described conical gear with it is described
The transmission output shaft that transmission input shaft is connected；The both ends of the transmission input shaft are respectively by spring bearing with being correspondingly arranged
Five-way tube lid in Five-way tube both sides is fixedly connected, and the both ends of the transmission input shaft are fixed with bicycle pedal connect respectively
It connects；The transmission output shaft by the thrust ball bearing and needle bearing that are arranged and is arranged on the Five-way tube and rear chain stay respectively
Between output shaft bearing mounting base be fixedly connected.
Further preferred scheme is that the transmission input shaft is five axises.
Further preferred scheme is, the transmission output shaft is by the thrust ball bearing axial limiting, and by the rolling
Needle bearing radially limits.
Further preferred scheme is, the output shaft bearing mounting base by the key pin of setting and the Five-way tube and after
Chain stay is fixedly connected.
A kind of bicycle, including above-mentioned bicycle drive.
A kind of electric bicycle, including above-mentioned bicycle drive.
The beneficial effects of the utility model：Traditional depth is replaced using thrust ball bearing and needle bearing in the utility model
Ditch ball bearing, since the axial load of thrust ball bearing is big, the radial load bigger of needle bearing, and the volume of needle bearing is more
It is small so that the overall structure of transmission device is compacter, volume smaller, and service life is longer；And the setting of above structure is also
So that the dimensional structure of vehicle frame aluminium section bar is smaller, material has not only been saved, moreover it is possible to leave the more installation spaces of other component for,
The further layout for causing part is looser reasonable.
Description of the drawings
Fig. 1 is the main view schematic diagram of the utility model.
Fig. 2 be in the utility model Fig. 1 A-A to structure diagram.
Specific embodiment
Shown in Fig. 1, Fig. 2, it is related to a kind of bicycle drive, including Five-way tube 3 and rear chain stay 7, in the Five-way tube 3
Transmission input shaft 1 is provided with, is provided with what conical gear was connected with the transmission input shaft 1 in the rear chain stay 7
Transmission output shaft 4；The both ends of the transmission input shaft 1 by spring bearing 5 and are correspondingly arranged at the five of 3 both sides of Five-way tube respectively
Siphunculus lid 6 is fixedly connected, and the both ends of the transmission input shaft 1 are fixedly connected respectively with bicycle pedal (not shown)；It is described
Transmission output shaft 4 by the thrust ball bearing 9 and needle bearing 10 that are arranged and is arranged on the Five-way tube 3 and rear chain stay 7 respectively
Between output shaft bearing mounting base 8 be fixedly connected.
Further preferred scheme is that the transmission input shaft 1 is five axises.
Further preferred scheme is, the transmission output shaft 4 is by 9 axial limiting of thrust ball bearing, and by described
Needle bearing 10 radially limits.
Further preferred scheme is key pin 2 and the Five-way tube 3 of the output shaft bearing mounting base 8 by setting
It is fixedly connected with rear chain stay 7.
The above-mentioned bicycle drive of the utility model can be applied not only in the transmission device of bicycle, can be with
Applied in the transmission device of electric bicycle.
Traditional deep groove ball bearing is replaced using thrust ball bearing and needle bearing in the utility model, due to thrust ball axis
The axial load held is big, the radial load bigger of needle bearing, and the volume smaller of needle bearing so that the entirety of transmission device
Structure is compacter, volume smaller, and service life is longer；And the setting of above structure is also so that the size of vehicle frame aluminium section bar
Structure is smaller, has not only saved material, moreover it is possible to leave the more installation spaces of other component for, it is further so that the layout of part
It is looser reasonable.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
