Above-mentioned purpose of the present utility model is realized by following technical scheme.
A kind of driving device of bicycle, it is characterized in that: the right side and the rear axle right side of the axis five-way pipe of bicycle are provided with axis gear case and rear axle gear case, the axis right-hand member passes behind the axis gear case and the right pedal concrete mutually, in the axis gear case, set firmly an axis circular cone bevel gear on the axis, this axis circular cone bevel gear and conicle bevel gear engagement, this conicle bevel gear center sets firmly a transmission shaft, this transmission shaft passes the crotch pipe that leads to rear axle, its two ends are located in axis gear case and the rear axle gear case with bearing frame, in the rear axle gear case, the end of transmission shaft sets firmly a circular cone bevel gear, this circular cone bevel gear and back shaft bevel gear engagement, this back shaft bevel gear is slidedly arranged on the rear axle with bearing, sets firmly a power-transfer clutch between this back shaft bevel gear and rear wheel hub.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
Square is processed at the axis two ends.
The set bearing in axis two ends, its left end bearing is to be made of left steel bowl and ball, the right-hand member side bearing is to be made of right steel bowl and needle roller; Outside left steel bowl, also be provided with left jam nut.
Axis is provided with sleeve pipe outward, and this sleeve pipe and bicycle car crotch axis five-way are combined as a whole with excessively cooperating; Above-mentioned axis gear case and sleeve pipe are formed in one.
Axis conical gear and axis are to be integral with being threaded.
The front end radial thrust ball bearing outside of transmission shaft is provided with pressure ring and preceding lid; Stop compressing tablet, inner pressure ring and preceding lid in the radial thrust ball bearing outside, rear end of transmission shaft is provided with.
Rear axle is set up in the rear wheel hub two ends with radial ball bearing; End at the back shaft bevel gear is provided with the end face thrust bearing.
Advantage of the present utility model is: adopt the gear change transmission, the efficient height, speed is fast, light, steady, noise is little, installation is easy to adjust.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings:
Fig. 1 is the schematic perspective view of the utility model bicycle.
Fig. 2 is the axis part scheme drawing of the driving device of the utility model bicycle.
Fig. 3 is the hind axle part scheme drawing of the driving device of the utility model bicycle.
Fig. 1,2, shown in 3, a kind of bicycle drive provided by the utility model, it is gear system, wherein: the right side and rear axle 2 right sides of the axis five-way pipe 1 of bicycle are provided with axis gear case 3 and rear axle gear case 4, axis 5 right-hand members pass axis gear case 3 backs and right pedal 6 concrete mutuallies, in axis gear case 3, set firmly an axis circular cone bevel gear 7 on the axis 5, this axis circular cone bevel gear 7 and a conicle bevel gear 8 engagements, these conicle bevel gear 8 centers set firmly a transmission shaft 9, this transmission shaft 9 passes the crotch pipe 10 that leads to rear axle 2, its two ends are set up in axis gear case 3 and the rear axle gear case 4 with bearing 11, in rear axle gear case 4, the end of transmission shaft 9 sets firmly a circular cone bevel gear 12, this circular cone bevel gear 12 and 13 engagements of back shaft bevel gear, these back shaft bevel gear 13 usefulness bearings are slidedly arranged on the rear axle 2, and 15 of this back shaft bevel gear 13 and rear wheel hubs set firmly a power-transfer clutch 16; This power-transfer clutch is a three cylindrical formula overriding clutch.
In embodiment illustrated in fig. 2, square is processed at the axis two ends, for pedal 6 is installed; Axis 5 two ends are provided with bearing, and the left end bearing is to be made of left steel bowl 17 and ball 18, and the right-hand member side bearing is to be made of right steel bowl 19 and needle roller 20, and endplay is adjusted by left jam nut 21 and left steel bowl 19.Axis is provided with sleeve pipe 22 outward, and this sleeve pipe 22 and bicycle car crotch axis five-way 1 form excessively to cooperate and be combined as a whole, and above-mentioned axis gear case 3 is formed in one with sleeve pipe 22; Present embodiment axis conical gear 7 and axis 5 are to be integral with being threaded.
The front end of transmission shaft 9 is to combine with axis gear case 3 by radial thrust ball bearing 11; Its outside is provided with pressure ring 23 and preceding lid 24; The rear end of transmission shaft 9 is to combine with rear axle gear case 4 by radial thrust ball bearing 11; Stop compressing tablet 25, inner pressure ring 26 and preceding lid 27 in its outside is provided with.
