Abstract
A novel dual-flywheel bicycle hub comprises a hub shell, a main shaft and a ratchet flywheel. Two ends of the hub shell are sleeved on the main shaft through a bearing, the hub shell comprises a middle tube which is provided with a face plate, the ratchet flywheel is mounted on one side of the hub shell, a fixed flywheel mounting seat is arranged on the other side of the hub shell, and a fixed flywheel is fixedly mounted on the fixed flywheel mounting seat. The novel dual-flywheel bicycle hub is simplified in manufacturing process and mounting mode.
Description
Technical field
The utility model belongs to bicycle hub.
Background technology
Common bicycle round trip flight wheel flower hub generally installs and fixes formula flywheel one end needs car to go out positive and negative tooth line, and Stationary flywheels needs the car inner tooth thread with fixing locking plate, and manufacturing process is complicated.So it is just necessary to simplify the Stationary flywheels mounting means of flower hub manufacturing process, simplification round trip flight wheel flower hub.
Summary of the invention
In order to overcome complicated, the complicated deficiency of mounting means of manufacturing process of existing round trip flight wheel flower hub, the utility model provides the new type double flywheel bicycle hub of a kind of simplified manufacturing technique and mounting means.
The utility model solves the technical scheme that its technical matters adopted:
A kind of new type double flywheel bicycle hub; Comprise hub shell body, main shaft and ratchet-type flywheel, said hub shell body two ends are contained on the main shaft through bearing carrier ring, and said hub shell body comprises middle pipe; Pipe is provided with floral disc in said; One side of said hub shell body is installed the ratchet-type flywheel, and the opposite side of said hub shell body is provided with fixedly flywheel mount pad, and Stationary flywheels is fixedly mounted on the said fixedly flywheel mount pad.
Further, said fixedly flywheel mount pad has left mounting hole, and said Stationary flywheels has right mounting hole, and nut passes said left mounting hole captives joint with right mounting hole.Certainly, also can adopt other captive joint modes.
The outer ring of said Stationary flywheels is a gear ring, and the inner ring of said Stationary flywheels is connected on the said fixedly flywheel mount pad.
The inner ring of said Stationary flywheels is provided with at least two salient points that wait circular arc to be provided with at interval, and said Stationary flywheels mount pad is provided with the groove that cooperates with said salient point.Certainly, also can groove be set inner ring, the mode of salient point is set on the mount pad, perhaps adopt other clamping locate modes.
The beneficial effect of the utility model mainly shows: simplified manufacturing technique and mounting means.
Description of drawings
Fig. 1 is the constructional drawing of novel light round trip flight wheel bicycle flower hub.
Fig. 2 is the fixing structural representation of flywheel mount pad.
Fig. 3 is the structural representation of Stationary flywheels.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～3, a kind of new type double flywheel bicycle hub comprises hub shell body 2, main shaft 9 and ratchet-type flywheel 8; Said hub shell body 2 two ends are sleeved on the main shaft through bearing 1; Pipe 7 during said hub shell body 2 comprises, said middle pipe 7 is provided with floral disc 6, and a side of said hub shell body 2 is installed ratchet-type flywheel 8; The opposite side of said hub shell body 2 is provided with fixedly flywheel mount pad 5, and Stationary flywheels 4 is fixedly mounted on the said fixedly flywheel mount pad 5.
Further, said fixedly flywheel mount pad 5 has left mounting hole, and said Stationary flywheels 4 has right mounting hole, and nut 3 passes said left mounting hole captives joint with right mounting hole.Certainly, also can adopt other captive joint modes.
The outer ring of said Stationary flywheels is a gear ring, and the inner ring of said Stationary flywheels is connected on the said fixedly flywheel mount pad.
The inner ring of said Stationary flywheels is provided with at least two salient points that wait circular arc to be provided with at interval, and said Stationary flywheels mount pad is provided with the groove that cooperates with said salient point.Certainly, also can groove be set inner ring, the mode of salient point is set on the mount pad, perhaps adopt other clamping locate modes.
In the present embodiment, six nuts of said Stationary flywheels 4 usefulness 3 are fixing.
The utility model has improved the structure of hub shell body; Be provided with Stationary flywheels mount pad 5 at floral disc one end; Follow-up needs production Stationary flywheels 4, does not also need to carry out the positive and negative tooth line of car again, only needs with six hold-doun nuts Stationary flywheels is installed on the Stationary flywheels mount pad during follow-up assembling.
