Abstract
The utility model discloses a bicycle hub assembly. The bicycle hub assembly comprises a hub cover (7). The hub cover (7) is installed on a central spindle (1) through a first bearing (6) and second bearing (9). A ratchet wheel installation cavity (7a) is formed in the right portion of the hub cover (7). A one-way ratchet mechanism is installed in the ratchet wheel installation cavity (7a) and arranged on the central spindle (1) in a sleeved mode. According to the bicycle hub assembly, the one-way ratchet mechanism is directly connected with an output shaft in a bicycle transmission system rather than that the hub is directly connected with an output gear in the transmission shaft. Thus, the instillation efficiency is greatly improved, the working efficiency is high, errors caused by accumulated installation of components are avoided, and maintenance is convenient.

In order to overcome above deficiency, except drive mechanism is improved, also need flower-drum to improve, therefore design the flower-drum that a kind of efficiency of assembling is high and necessitate.
Utility model content
For solving above technical matters, the utility model provides a kind of novelty simple in structure, highly versatile, the bicycle drive shaft assembly that efficiency of assembling is high.
Technical scheme is as follows:
A kind of bicycle drive shaft assembly, comprise flower-drum skin (7), this flower-drum skin (7) is arranged on axle core (1) through clutch shaft bearing (6) and the second bearing (9), its main points are: described flower-drum skin (7) right part is provided with ratchet installation cavity (7a), in this ratchet installation cavity (7a), single direction ratchet mechanism is installed, outside this unidirectional sour jujube mechanism, is enclosed within on described axle core (1).
Adopt above structure, single direction ratchet mechanism in the utility model is directly connected with the output shaft in bicycle transmission system, instead of flower-drum is directly connected with the output gear in driving system, therefore, the utility model has only designed an interface while connection with outside transmission device, so installation effectiveness improves greatly, work efficiency is high, also solved the error that accumulative total installing component causes, easy to maintenance.
As preferably: described single direction ratchet mechanism comprises matrix (14) and ratchet (10), on this matrix (14), be evenly provided with outside the described matrixes of at least three ratchets (12) (14) and ratchet (12) described ratchet (10) is set, on the endoporus hole wall of described matrix (14), be provided with spline, described ratchet (10) lateral wall is threaded with described ratchet installation cavity (7a), described matrix (14) one sides are provided with elastic spring (11), on this elastic spring (11) excircle, be provided with the groove (11a) matching with described ratchet (12), between described elastic spring (11) and matrix (14), be provided with straight pin (13).Adopt above structure, when use, matrix is connected with the output axle key of driving system, thereby realize the output of power, described ratchet lateral wall is threaded with described ratchet installation cavity, and power passes to ratchet through ratchet, ratchet passes to flower-drum skin again, realizes the final output of power.
As preferably: described clutch shaft bearing (6), near described ratchet installation cavity (7a), is provided with pad (8) between described clutch shaft bearing (6) and single direction ratchet mechanism, so install more reliable.
As preferably: arrange porose with back-up ring (5) at the described flower-drum skin (7) in described clutch shaft bearing (6) left side, on the described axle core (1) in this back-up ring (5) left side for hole, be connected with nut (4), this nut (4) right-hand member props up described the second bearing (9), can realize the installation of flower-drum skin and axle core.
As preferably: described axle core (1) left part is connected with hexagon nut with flange (2), is set with packing ring (3) on the described axle core (1) on this hexagon nut with flange (2) right side.
Beneficial effect: the bicycle drive shaft assembly that adopts above technical scheme, this novelty simple in structure, compactness, at least have following feature: first is that commonality is stronger, the design of this flower-drum, make the connection mode of flower-drum and driving system realize fast speed assembling, efficiency of assembling is high; The secondth, adopt after this flower-drum assembly, the driving efficiency of driving system is high, stationarity good, have good ride comfort.
