Description
Technical field
This utility model relates to a kind of bicycle drive shaft, more specifically, particularly relates to a kind of bicycle drive shaft adopting pulley drive.
Background technology
Existing bicycle transmission system belongs to rigidity chain drive effect, due to the frictional force of chain in traditional drive system, causes that bicyclist bestows the strength ridden and absorbed by the frictional force of chain, makes bicyclist cannot easily ride the long way of relatively long distance. Although there being different gearshift situations to use in the process of transmission, but bicyclist's force is not proportional with driving force after all.
In the process of transmission, the flower-drum of bicycle has critical problem to exist, and traditional bicycle all uses the flywheel of monolithic or multi-disc, although this structure is no problem, also used by majority now, but because the intervention of frictional force, cause that bicyclist cannot easily exert a force and ride.
For being badly in need of wanting the earth of environmental protection, more ride in order to convenient, needing the problem solved is allow the force of bicyclist obtain maximized driving force, when bicyclist imposes on the state that the pedal force of bicycle reaches bicyclist's feeling relaxed, bicyclist just can really be ready by bike, then needs the field using the concept of industry driving belt to enter bicycle.
In bel-drivenn process, need to bring belt concept into bikedom, being accomplished by changing the front chain wheel of standard bicycle into front belt driving wheel, rear flywheel part changes into belt holder and uses, the structure of outward appearance to be designed to meet the combination of trailing wheel belt holder and use by flower-drum part. If improving only with simple structure, adopting the way making tradition column foot cassette flywheel, by the division center of rear belt pulley, being adapted to snap in the faying face of clamp type flower-drum. This simply changing, length dimension after bonding is long, is easily caused needs and increases and pad a lot of pads. After the torque value of belt pulley is excessive, after cause pad torsional deformation.
After hub structure is popular on earth centuries, gradually develop into two kinds of trend, one is to change in internal structure, makes internal speed-changing system, and the power through transmission changes the rotary regimes within flower-drum, and reach the effect of speedup, one is to change in external structure, makes outer speed change system, then develops into multistage flying wheel, make through derailleur to chain can be converted the progression that can be suitable at limited stall space of opening, increase or reduce strength or the speed of bicyclist.
