Abstract

The utility model discloses a high speed power-saving bicycle. The utility model is characterized in that a driving gear adopts a gear and a lever structure, the multiple of the speed increase of the gear and lever structure is the gear ratio between a big gear and a small gear, and the multiple of the labor saving of the gear and lever structure is the length ratio between the principal and the subordinate arms of the lever. Therefore, compared with the common bicycle, the utility model has the advantages of fast speed, labor saving, and low cost.

Description

The high speed labour-saving bicycle

The utility model relates to a kind of high speed labour-saving bicycle, especially bicycle drive.

The ordinary bicycle of people's use at present, the sprocket wheel chain structure that its driving device all adopts, the disadvantage of this structure are that moving velocity is slow, and be not laborsaving, especially go up a slope, cargo, shortcoming is more outstanding, and people have released derailleur for this reason, has the bicycle of motor, yet the too fat to move complexity of derailleur structure, operation is also inconvenient, and then noise is big for the car of band motor, the cost height.

The purpose of this utility model is to provide a kind of moving velocity fast, the laborsaving and low noiseless high speed labour-saving bicycle of cost.

The utility model is on the basis of ordinary bicycle, increase a supporting plate and a locating plate, driving device then is made up of big gear wheel, miniature gears, connecting rod, lever, pull bar, ratchet, Positioning Gear, miniature gears is installed on the locating plate and with big gear wheel and meshes, connecting rod one end and miniature gears off-centre are hinged, the other end and lever are hinged, pull bar one end and lever are hinged, the other end and ratchet off-centre are hinged, lever and ratchet are installed on the supporting plate, and ratchet is meshed with Positioning Gear on being installed in rear vehicle shaft.

For making between connecting rod and miniature gears eccentric throw adjustable, be provided with a regulating tank on the miniature gears.

Below in conjunction with accompanying drawing the utility model is described in detail:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the cutaway view of Fig. 1 along A-A line.

Fig. 3 is the cutaway view of Fig. 1 along B-B line.

As can be seen from Figure 1, the installation site of big gear wheel 1 of the present utility model is identical with the installation site of ordinary bicycle sprocket wheel, in conjunction with Fig. 2 as can be seen, an affixed locating plate 9 on the vehicle frame of big gear wheel center for miniature gears 2 location, having one in two foot-operated bent axles is biased on the big gear wheel 1, connecting rod 3 is hinged on the regulating tank 10 on the miniature gears 2, also can see in conjunction with Fig. 3, supporting plate 8 is to be fixed on the vehicle frame 11 at rear wheel wheel shaft place, be used for fixing ratchet 6 and lever 4, the endoporus of ratchet 6 is a ratchet, the outer ring is a gear, and be meshed with Positioning Gear 7, an eccentric shaft 12 is housed on the supporting plate 8, above ratchet 6 and pull bar 5 are installed in, pull bar 5 is in dead center position ratchet 6 idle running might take place when preventing to get on the bus, therefore on eccentric shaft 12, with supporting plate 8 adjacent face peripheries, be mutually 180 ° of ground and opened two sour jujube grooves, then adorned a backing pin on the supporting plate 8, prevent ratchet 6 idle running, big gear wheel 1 is 6: 1 with the ratio of number of teeth of miniature gears 2, therefore work as people and trample sole one circle, can make wheel change 6 circles, 4 two sections arm of force ratios of lever are 1: 2, and it is than adopting laborsaving one times of lever, therefore use not only straightforward man but also laborsaving of the utility model speed.

The utility model has adopted gear, lever construction, make that bicycle speedup multiple is the ratio of number of teeth of big gear wheel and miniature gears, speed is multiplied, and the labour-saving effect has then been played in the lever transmission, and cost is suitable with ordinary bicycle, has tangible practical value and application prospect.
