Abstract
The utility model relates to a stepless speed variator of a chain bicycle, comprising a back wheel shaft, a flywheel and a bearing which are arranged on a back wheel of a bicycle, and chains. Two conical wheels with opposite conical ends are sheathed on the back wheel shaft, the opposite points of the conical ends of the two conical wheels form a wedge-shaped groove, the outer end of one conical wheel is provided with a spring, the outer end of which is provided with a baffle plate, and the outer end of the baffle plate is provided with the bearing. Both side edges of chain sheets of the chains form symmetrical slopes, and the chains are matched and connected to the wedge-shaped groove formed by the opposite conical ends of the two conical wheels of the centre shaft gear and the back wheel shaft of the bicycle. The stepless speed variator of a chain bicycle of the utility model has the advantages of simple structure, easy production and steady work.
Description
The utility model belongs to bicycle drive, particularly a kind of chain type bicycle toric transmission.
At present, the change-speed box in the bicycle drive is generally common step change transmission, is that the gear cluster by coaxial different radii constitutes, and mostly relies on steel wire to spur the conversion that realizes between its gear during speed change, to reach the purpose of step change.This gear shift mode is that the cyclist realizes by manual regulation according to the riding condition of oneself.The shortcoming of this gear shift mode is comparatively to bother, and if people's speed change number of times inappropriate the time cross the damage that is easy at most cause to change-speed box.
The purpose of this utility model is to design a kind of chain type bicycle toric transmission, it makes the step change transmission in the bicycle drive become toric transmission, and change the existing shortcoming of step change transmission, when allowing people by bike simultaneously, in speed change unconsciously, the trouble of removing hand gear from.
The technical solution of the utility model: a kind of chain type bicycle toric transmission, comprise that the flywheel that is equipped with on the hind axle that places on the bicycle rear, the hind axle is with bearing and be connected bicycle middle shaft and the chain of hind axle, it is characterized in that on hind axle, being set with two relative conical wheels of awl end, two conical wheels awl end opposite position forms a webge slot, match with flywheel and be connected in one conical wheel outer end, there is a springing that is sleeved on the hind axle another conical wheel outer end, baffle plate is equipped with at place, springing outer end, place, baffle plate outer end dress bearing; Chain sheet dual-side on the said chain is the domatic of symmetry, and chain sheet dual-side is the domatic chain of symmetry and is connected and holds between the webge slot of relative formation in the two conical wheels awl of bicycle middle shaft gear and hind axle.
The bloated wheel of regulating the chain degree of tightness also can be housed on the above-mentioned said bicycle rear shaft.
Be equipped with above-mentioned said another conical wheel outer end, and to place the springing on the hind axle can be spring or reed.
There is the texture that can increase friction the webge slot inboard that above-mentioned said two conical wheels awl end opposite position forms, and the chain-sheet of chain dual-side is on symmetry domatic also cooresponding texture.
Above-mentioned said webge slot inboard can be profile of tooth line or netted line with the domatic texture that all increased friction that chain sheet dual-side is symmetry.
Further specify present technique below in conjunction with drawings and Examples.
Accompanying drawing 1 is the hind axle position structural representation of the related a kind of chain type bicycle toric transmission of the utility model.
Accompanying drawing 2 be chain in the related a kind of chain type bicycle toric transmission of the utility model the chain sheet just, the side structural representation.
Wherein: 1 is bicycle rear shaft, and 2 is bicycle freewheel, and 3 is the conical wheel as flower wheel, and 4 is chain, and 5 is another conical wheel as flower wheel, and 6 is spring, and 7 is baffle plate, and 8 is bearing, and 9 is symmetrical domatic on the chain-sheet of chain, and 10 is webge slot.
Embodiment: a kind of chain type bicycle toric transmission (see figure 1), comprise that the flywheel 2 that is equipped with on the hind axle 1 that places on the bicycle rear, the hind axle is with bearing 8 and be connected bicycle middle shaft and the chain of hind axle 14, it is characterized in that on hind axle 1, being set with relative two conical wheels 3 and 5 of awl end, two conical wheels 3 and 5 awl end opposite positions form a webge slot 10, match with flywheel 2 and be connected in one conical wheel, 3 outer ends, there is a spring 6 that is sleeved on the hind axle 1 another conical wheel 5 outer ends, baffle plate 7 is equipped with at place, spring 6 outer ends, place, baffle plate 7 outer ends dress bearing 8; Chain sheet dual-side on the said chain 4 is the domatic 9 of symmetry, and the chain 4 that chain sheet dual-side is symmetry domatic 9 is connected and bores 10 of webge slots holding relative formation in the bicycle middle shaft gear and two conical wheels 3 and 5 of hind axle 1.
Principle of work of the present utility model: the bicycle middle shaft gear is a driving wheel, two conical wheels 3 and 5 that are installed on the bicycle rear shaft 1 are flower wheel, the chain sheet dual-side that is connected in 10 of the webge slots of two conical wheels 3 of bicycle middle shaft gear and hind axle 1 and relative formations of 5 awl ends is the power of the domatic chain of symmetry 4 transmission driving wheels drive flower wheels, chain 4 work that both can match this moment with the gear driving wheel, work can match with the sheave flower wheel again, friction between chain 4 utilizations and conical wheel 3 and 5 drives whole flower wheel, in transferring power, with the driving wheel rotating speed, the increase of power, cause the increase of chain to flower wheel conical wheel 5 centripetal force, make conical wheel 5 stressed and horizontal mobile along axle, spring 6 is compression thereupon also, thus, also just be equivalent to reduce the radius of flower wheel, make ratio changing, thereby play infinite variable speed effect, finish speed-change process.
Superiority of the present utility model is: chain strip-type bicycle buncher has structure Simply, be easy to make, stable working, vibration absorption ability is strong, and driving chain is easy to the advantages such as replacing, In the technological development of bicycle buncher and the upgrading wide commercial promise is arranged.
