Description
Technical field
The purpose of this utility model is intended to the improvement of power car (comprising motor bike, Electrical Bicycle) spoke in use and dismounting, replacing, maintenance and perfect, and this purpose is also served in the improvement of flower hub.
Background technology
Since the blank invention of 1790 annual proper motion cars, especially the Reynolds of Britain in 1869 adopts wire spoke to replace since wooden and the wrought iron spoke, bicycle is through 100 years of development, its rapid technological improvement, it is that the power car performance of representative constantly creates greater achievements that a large amount of new material new process The application of new technique make with the bicycle, comprise the variation of spoke material, also occurred the nonmetallic wheel rim supporter of a large amount of non-spokes simultaneously.Except the good power car of the condition of road surface place of competing for speed, light, support and the cushioning effect of metal spoke still can not be substituted in all-terrain baby is used so far.
But over more than 100 year, the design of spoke and mounting means still do not have too big variation so far.The spoke that takes place in the use of power car damages related maintain and replace, often needs the parts such as flywheel, chain guard, chain, derailleur and heel brace of removal force car, even removes Tire ﹠ Tube and could change and keep in repair, and wasting time and energy increases service expenditure simultaneously.Importantly, owing to parts such as frequent dismounting flywheels, influence the Total tune of power car, caused the failure in service rate to increase.
Especially at present a large amount of power cars adopt the band tyre of rubber, polyurethane or other materials or the use of other non-dismountable tire, comprise wheelchair, perambulator or some instruments of labour etc. among a small circle, and the damage of spoke often causes scrapping of whole wheel.
In Chinese invention patent 201110462022.6 in the applicant's application and the enforcement of the Chinese utility model patent 201120578218.7 in the application, the applicant has just met with traditional spoke to improving the restriction of tire for the improvement of tire, and this also is the reason that present patent application occurs.
In the retrieval of passing patent, also have much to the improved conception of power rung bar, just announced the bicycle spoke of a kind of " Z " shape hook as Chinese patent 02200075.5, secondly but there is following deficiency in it: at first need remove a tyre to tighten the bar mother in the replacing of spoke equally, the elbow of spoke can't hook in the colored hub bore when some flower hub and brake disc or electric vehicle motor are intermittently too tight.And Chinese patent 201120206179.8 and Chinese patent 92213764.1 are except there being above deficiency, also have another defective simultaneously: the effect that spoke not only only tightens up after female tension by bar, wheel movement or when static spoke also have the effect of supporting simultaneously.Do not have under the situation of steel cap at above-mentioned patent spoke elbow, acutely travel, jolt or bear a heavy burden excessive, violence is controlled etc. all might make the spoke elbow break away from the flower hub.Chinese patent 98233139.8 discloses a kind of " protruding " word hub in addition, but its defective is the effect of only tightening up colored hub and wheel rim in use, when spoke needed a bearing force, the spoke elbow slides the base to proceeds posterolateral along " protruding " word, and was not feasible.
Summary of the invention
In order to overcome the defective of existing power rung bar and the design of flower hub, the utility model discloses a kind of new spoke and the improved design of flower hub, described design is widely used in uses spoke class vehicle, comprises power car, motor bike and Electrical Bicycle etc.
