Abstract
The utility model relates to a full chain cover of speed-changing bicycle. It includes the cover body 2, preceding derailleur rubber lid 1, rear derailleur lid 3 and inboard rear axle hole baffle. Forming a totally enclosed housing that fully encloses the chain, sprocket and transmission. The chain and the chain wheel can be prevented from being polluted by splashed muddy water and dust. Opening the rubber cover of the front derailleur and adding 20 to the chain#The engine oil has well-lubricated closed chain transmission, greatly reduces the abrasion of a transmission system and prolongs the service life. The chain wheel transmission device does not hinder the work of the transmission, and can also avoid the phenomenon that oil stains on clothes corners, skirt edges and trouser mouths of people are polluted or are involved between the chain and the chain wheel to be occluded so as to influence the driving safety.
Description
The utility model is that a kind of width between centers that is applicable to is the whole chain cover of 415mm chain-driving variable speed bicycle.It comprises cover body, front chain shifter serum cap, Rear Derailleur lid and inboard back axis hole plate washer.
Because the raising of living standards of the people needs more comparatively desirable commodity.Along with science and technology development, constantly released racing car, mountain bike and various variable speed bicycle in recent years in the bicycle field.They are quick more adjustable again than ordinary bicycle, and light laborsaving, compact conformation is attractive in appearance, more and more are subjected to people's welcome and favor, have now become common manpower transportation.Yet variable speed bicycle all is the open kinematic chain transmission, this just makes driving system be stain by muddy water, dust easily, and easy-to-rust is easy to wear and cause chain rupture, do solid dumb, and stain the human body clothing again easily or be involved in chain and sprocket wheel between the hidden danger of interlock traffic accident under cover.
In order to solve the existing problem of above-mentioned variable speed bicycle chain-driving, many design engineers have also been done a large amount of work.Designer as Beijing, Shanghai, Shijiazhuang, Guangdong and Chengdu and other places from different angles, has designed successfully the variable speed bicycle chain cover with stressing, but has been half chain guard, can not address the above problem fully.
The purpose of this utility model provides a kind of variable speed bicycle whole chain cover.It can prevent effectively that silt that dust, rainwater splash is to the chain in the cover chamber, the erosion of sprocket wheel; become closed kinematic chain transmission with good lubrication; thereby the wearing and tearing of driving system have been alleviated greatly; prolonged service life; do not hinder the work of change-speed box again; also can be to frequent and human body clothing angle, shirt rim, leg opening, the chain that may contact shields.
The purpose of this utility model is achieved in that it comprises cover body, front chain shifter serum cap, Rear Derailleur lid and inboard back axis hole plate washer.With pressing plate, screw cover body interior front and rear portion, the outside are fixedly mounted on the chain stay pipe of vehicle frame, install the same with the ordinary bicycle whole chain cover.The cover chamber type shape of variable speed bicycle whole chain cover is to come design-calculated according to the limit of sports record locus of dialling chain device arm and chain.Above cover body by the seat tube place have an oblong stepped hole promptly "
" the shape hole, so that when chain guard is installed, the front chain shifter arm can penetrate this hole, and can keep the function of group chain arm constant, has a serum cap can cover this hole closely again above tightly being enclosed within the front chain shifter arm outward.Have a Rear Derailleur active window at rear portion, the chain guard outside, this window does not hinder Rear Derailleur shared locus under the speed change situation, and covers window with the Rear Derailleur lid.In order to adjust change-speed box easily, lid and chain guard adopt the coupling method of eye-splice-type, and just the energy easy to disassemble and assemble is provided with buckle up simultaneously on cover body, and lid is not come off.In order to reach the purpose of totally-enclosed driving system, axis hole after an axial baffle being housed on the bicycle rear shaft shoulder block the cover body inboard.
Contrast below that Fig. 1--Fig. 4 is described in detail the utility model:
Fig. 1 is a variable speed bicycle whole chain cover lateral elevational view
Fig. 2 is the birds-eye view of variable speed bicycle whole chain cover cover body
Fig. 3 is a variable speed bicycle whole chain cover A--A section-drawing
Fig. 4 is a variable speed bicycle whole chain cover B--B semi-sictional view rotation diagram
With reference to Fig. 1: the variable speed bicycle whole chain cover comprises cover body (being made up of chain disk cover 1, cover body 3 and cover tail 4), front chain shifter serum cap 2, Rear Derailleur lid 5 formations.Earlier front chain shifter serum cap 2 is enclosed within front chain shifter arm top, will dials chain device arm again and insert in the cover body 3, with pressing plate 7, pressing plate 6 and screw will cover body 3 interior front respectively and rear portion, the outside is fixedly mounted on the vehicle frame chain stay pipe.Install trailing wheel, chain, chain drum, adjust change-speed box, install chain disk cover 1 and cover tail 4, and fastening with screw.Insert Rear Derailleur lid 5 at last and cover Rear Derailleur cover body window.
Fig. 2 is the birds-eye view of variable speed bicycle whole chain cover cover body, be to be in the space end position and design-calculated according to variable speed bicycle chain and change-speed box, so this chain guard transversal surface everywhere just changes with the limit space position that chain movement changes, and has a thick characteristic of thin tail.
Fig. 3 is a whole chain cover A--A section-drawing, this shows that the cover body is to be combined by variform two half blocks separately, adopt flange connect promptly "
".
Fig. 4 is a whole chain cover B--B semi-sictional view rotation diagram, and the coupling method of seeing Rear Derailleur lid and cover body from figure is an eye-splice-type.Mainly be when adjusting change-speed box, be convenient to readily removablely, easily adorn this lid.
In order to verify engineering reliability of the present utility model, and products thereof practicality.Making is on probation again by scheming to make, try out, revise design in order to reach this purpose designer.Well-designed repeatedly through more than a year made entrucking and tries out, reached designing requirement, and result of use is good, meet manufacturing, assembling, maintenance process requirement.
The utility model is with the sheet steel drawing, sprays paint or electroplate, polish, also can injection molded.
