Abstract
The utility model relates to a transmission mechanism of a high-speed bicycle, which is provided with a crank, a gear, a chain wheel, a chain and a fly wheel. The utility model is characterized in that one-stage to two-stage gear transmission exists between the gear which is fixed on the crank and the chain wheel. The utility model has the advantages of high speed of bicycles, high stability, high reliability, less possibility of malfunction, low cost and convenient installation.
Description
The utility model relates to a kind of transmission mechanism of bicycle.
Bicycle in the market mostly is the single-stage chain drive, owing to be subjected to the restriction of factors such as chain wheel diameter and intensity, can't satisfy people to improving the requirement of bicycle speed, and utility model: the multistage drive transmission device of the bicycle (patent No.: though ZL93208307.2) can improve the speed of bicycle, faults such as chain, chain jamming but appear taking off easily.
The purpose of this utility model is exactly for a kind of transmission device of high-speed bicycle is provided.
The technical scheme that realizes the utility model purpose is a kind of high-speed bicycle transmission device, has crank, gear, chain wheel, chain, flywheel, it is characterized in that: be fixed between gear on the crank and the chain wheel and be 1-2 level gear transmission.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is 1 grade of drive mechanism scheme drawing of high-speed bicycle.
Fig. 2 is 1 grade of drive mechanism scheme drawing.
Fig. 3 is 2 grades of drive mechanism scheme drawings of high-speed bicycle.
Fig. 4 is 2 grades of drive mechanism scheme drawings.
Embodiment 1:
Referring to Fig. 1,2, axle 7 and axle 8 are installed on the bicycle rack, axle 7 two ends are equipped with crank 5 and crank 6, crank 6 and gear 1 weld together, axle 8 one ends are equipped with gear 2, and mesh with gear 1: the other end is equipped with chain wheel 3, and flywheel 4 is installed on the hind axle 9, flywheel 4 and chain wheel 3 be in the same side, has chain 10 to connect between chain wheel 3 and the flywheel 4.Driven gear 1 rotates when manpower acts on crank 5 and the crank 6, and gear 1 driven gear 2 rotates, and gear 2 drives chain wheel 3 by axle 8 and rotates, and chain wheel 3 drives flywheel 4 by chain 10 and rotates, and flywheel 4 drives trailing wheel 11 and rotates.
Embodiment 2:
Referring to Fig. 3,4, axle 7, axle 8 and axle 13 are installed on the bicycle rack, crank 5 and crank 6 are installed in axle 7 two ends, crank 6 and gear 1 weld together, axle 8 two ends are equipped with gear 2 and gear 14, axle 13 two ends are equipped with gear 12 and chain wheel 3, gear 1 and gear 2 engagements, gear 14 and gear 12 engagements are equipped with flywheel 4 on the hind axle 9, flywheel 4 and chain wheel 3 are at homonymy, between have chain 10 to connect, when manpower acted on crank 5 and the crank 6, driven gear 1 rotated, gear 1 driven gear 2 rotates, gear 2 rotates by axle 8 driven gears 14, and gear 14 driven gears 12 rotate, and gear 12 drives chain wheel 3 by axle 13 and rotates, chain wheel 3 drives flywheel 4 by chain 10 and rotates, and flywheel 4 drives trailing wheel 11 and rotates.2 grades of transmissions are because of Duoed the one-level gear transmission than 1 grade of transmission, so can export higher rotating speed.
The utility model has the advantage of the speed that can increase substantially bicycle, again because gear is gear engagement, stability, reliability are strong, are difficult for breaking down. And cost is lower, and is easy for installation, is fit to promote.
