Abstract
The utility model relates to a drive part of a bicycle, particularly a mechanism device on the bicycle. A chain of the bicycle passes around a big chain disk according to the normal installation method, chain bores are sheathed in a flywheel gear and passed around the mechanism device from the top of a flywheel of a back wheel, and the chain is butted and jointed firmly so as to form a progressive transmission system of a back-pedaling bicycle, and thus a back-pedaling bicycle is formed. Accessories of the back-pedaling bicycle have the advantages of easy manufacture and convenient installation; the back-pedaling bicycle is interesting and portable.
Description
The utility model is relevant with the bicycle driving part, and a mechanical device on the bicycle of more specifically saying so, this device are installed in the flywheel outside of trailing wheel, and has constituted a driving system with big trochal disc, chain, flywheel.
Variable speed bicycle is exactly in the flywheel outside of trailing wheel a mechanical device to be installed at present, also constituted a driving system with big trochal disc, chain, flywheel, when people scrunch pedal forward, bicycle has just advanced, (being back-pedalling) because very heavy the races sky in the flywheel if kick backward, and bicycle just can not advance.
The purpose of this utility model provides a kind of device, is installed in the flywheel outside of bicycle rear, has constituted a driving system with big trochal disc, chain, flywheel, and when people's back-pedalling (kicking backward) pedal, bicycle has just advanced.Make people feel quite interesting and the distinguished sense of pride.
The purpose of this utility model is achieved in that
The chain of bicycle is walked around big trochal disc according to the normal mounting method, make the chain borehole jack go into flywheel teeth from the flywheel of trailing wheel top again and walk around this device, the chain butt joint firmly, promptly become the driving system that the back-pedalling bicycle advances, so the back-pedalling bicycle, it has just advanced.
The utility model concrete structure is provided by following examples and accompanying drawing.Fig. 1 is the driving system installation method scheme drawing that the back-pedalling bicycle advances.
Fig. 2, Fig. 3 are front elevation of the present utility model, lateral plan.A-frame among Fig. 2, Fig. 3 (1) is that materials such as cast steel or other alloy steels are made, and its angle is 60 °, support length of side 100MM.Be drilled with a hole (2) on the top of spider support (1), hole (2) diameter is 10mm.Respectively install a rolling bearing (3) at the both sides end of A-frame (1), the size of rolling bearing (3) is the same with the rolling miniature gears of present variable speed bicycle with installation method.So just constituted an accessory device of back-pedalling bicycle, signal according to Fig. 1, the flywheel outside that the accessory device of Fig. 2 is installed in bicycle rear again with the chain butt joint has firmly promptly constituted back-pedalling by frame and accessory device and chain and the bicycle that advances.
The accessory device manufacturing of back-pedalling bicycle is simple, easy for installation, and it is not only light but also interesting to ride the back-pedalling bicycle, more individual style is arranged, favorable economic benefit is more arranged.
Claims (3)
1, a kind of back-pedalling bicycle, it is to be made of frame and accessory device and chain, it is characterized in that chain walks around big trochal disc, walks around accessory device again above the flywheel of trailing wheel, the chain butt joint firmly, becomes the driving system that the back-pedalling bicycle advances.
2,, it is characterized in that accessory device is to be made by cast steel or alloy steel material according to claim 1, described back-pedalling bicycle.
