Abstract
The utility model discloses a kind of bicycle to float chain wheel, comprise axis and be arranged on the chain wheel body on axis, one section for installing endless chain transmission for bicycle on described axis is provided with groove, one section for installing endless chain transmission for bicycle on described axis is also provided with adapter sleeve, described adapter sleeve is provided with the groove corresponding with the groove on axis, ball is provided with between described groove and groove, described chain wheel body is fixedly installed on adapter sleeve, the utility model is by changing the annexation in prior art between chain wheel and axis, chain wheel body is movably arranged on axis, thus improve in prior art, chain wheel and flywheel are when transmission, the phenomenon that when high speed and low speed, oblique pull is serious.
Description
Technical field
The utility model belongs to bicycle art, is specifically related to a kind of bicycle and floats chain wheel.
Background technology
China is bikedom, the vehicle that are convenient, environmental protection low-carbon (LC) as the bicycle of riding instead of walk, obtain increasing people parent to look at, particularly folded bicycle, self structure, on the basis meeting go off daily function, can also bring it to take pubic transport, subway easily, even can take train, mountain bike, not available for the bicycle of the other types such as highway car.As the vehicle of travelling frequently, frequency of utilization is very high, and volume is little, places also very convenient at home.
In cycling, find the outer variable speed bicycle of single chain wheel, as the chain of transmission when transmission, oblique pull is universal phenomenon, the most at a high speed and dead slow time the most serious, in the structure of single chain wheel bicycle, chain wheel only has a slice, flywheel is but multi-disc, and the relative position of chain wheel and flywheel is fixing, the chain of transmission, speed change is from maximum tooth to minimum tooth flywheel, there occurs relative to flywheel and move axially, the axial location on chain wheel is above fixed, moving axially below on flywheel, cause oblique pull during transmission.As shown in Figure 1, due to the restriction of structure, the flywheel on trailing wheel and the relative position of flower-drum are fixing, and the relative position of flower-drum and spoke, wheel rim is also fixing, and chain oblique pull has continued always.
Constantly will trample crank in ride to make rear wheel, chain and chain wheel, flywheel produce radial pull due to pedal force, due to the existence of oblique pull, the flywheel in transmission and chain will produce axial pulling force, make chain when flywheel is constantly drawn forward simultaneously, outwards also there is the pulling force of (or inwards), in like manner: in the transmission of chain wheel and chain, there is radial pull forward and axial tension too, and when high speed or low speed, the direction of the axial tension between chain wheel with chain and between chain and flywheel is contrary, due to chain wheel and flywheel, this body structure of chain normalisation, for chain wheel, two sides of flywheel and the carrier bar side of chain will increase very large cliding friction, thus quickening chain, the wearing and tearing of flywheel and chain wheel, for bicyclist, due to the existence of useless frictions, equal riding speed, larger pedal force must be needed, add the physical consumption of bicyclist, this consumption is exactly done idle work.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of bicycle and floats chain wheel, overcomes the above-mentioned defect of prior art.
The purpose of this utility model is achieved through the following technical solutions:
Bicycle floats chain wheel, comprise axis and be arranged on the chain wheel body on axis, one section for installing endless chain transmission for bicycle on described axis is provided with groove, one section for installing endless chain transmission for bicycle on described axis is also provided with adapter sleeve, described adapter sleeve is provided with the groove corresponding with the groove on axis, be provided with ball between described groove and groove, described chain wheel body is fixedly installed on adapter sleeve.
Further, one section for installing endless chain transmission for bicycle on described axis is provided with three grooves, and described three grooves are uniformly distributed, and on described adapter sleeve, correspondence is provided with three grooves.
Further, also comprise lock pad, locked by lock pad between described chain wheel body and adapter sleeve.
Further, the both sides of described adapter sleeve are also provided with boot seal.
The beneficial effects of the utility model are: the utility model is by changing the annexation in prior art between chain wheel and axis, chain wheel body is movably arranged on axis, thus improves chain wheel and the flywheel phenomenon that oblique pull is serious when high speed and low speed in prior art.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by specification sheets below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the oblique pull schematic diagram of flywheel and chain wheel in prior art;
Fig. 2 is the utility model structural representation;
The structural representation of Fig. 3 the utility model axis;
Fig. 4 is the structural representation of the utility model adapter sleeve;
Fig. 5 is the structural representation of the utility model lock pad;
Fig. 6 is the structural representation of the utility model chain wheel body.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, bicycle floats chain wheel, the chain wheel body 1 comprising axis 2 and be arranged on axis, one section for installing endless chain transmission for bicycle on described axis is provided with groove 21, one section for installing endless chain transmission for bicycle on described axis is also provided with adapter sleeve 3, described adapter sleeve is provided with the groove 31 corresponding with the groove on axis, is provided with ball between described groove and groove, described chain wheel body is fixedly installed on adapter sleeve.
In the present embodiment, one section for installing endless chain transmission for bicycle on described axis is provided with three grooves, and described three grooves are uniformly distributed, and on described adapter sleeve, correspondence is provided with three grooves.
In the present embodiment, also comprise lock pad 4, locked between described chain wheel body and adapter sleeve by lock pad, the both sides of described adapter sleeve are also provided with boot seal 5.
The present embodiment, by changing the annexation in prior art between chain wheel and axis, makes chain wheel body movably be arranged on axis, thus to overcome in prior art chain wheel and flywheel high speed can low speed time oblique pull serious.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
