Abstract

The utility model relates to a 'shandi' bicycle. The front wheel and the handle bar of the bicycle is provided with an electricity generation device and an illumination device, and the rear wheel shaft of the bicycle is provided with a speed change mechanism. The upper main beam and the lower main beam are fixed to a lower bicycle seat through supporting beams, and the bicycle seat can be used for adjusting the fore-and-aft positions. The lower main beam is fixed with two groups of wheel disks which are driven by chains to attain the purpose of dual acceleration. The upper main beam is fixed with a hand-operated wheel disk to increase speed. The utility model has the advantages of low bicycle seat, stable bicycle body, strong support force of bicycle seat and higher bicycle speed.

Description

'Shandi' bicycle

The utility model relates to a kind of variable speed bicycle that is suitable for the mountain region.

In the prior art, speed change mountain bike vehicle seat comfort is poor, and can not give bearing force forward, and mountain bike does not generally possess hand boosting mechanism, when climbing or walking difficult highway section, can only lean on strength of one's legs like this, has limited the speed of a motor vehicle.

The purpose of this utility model provides that a kind of vehicle seat bearing force is strong, trick power-assisted two power mountain bikes simultaneously.

The purpose of this utility model realizes by following measure:

Two wheel shafts of this bicycle connect wheel, the front truck beam is car light 9 fixedly, the small generators that links to each other with car light 9 links to each other with the front truck beam, the hind axle partial fixing has speed-changing mechanism 4 and the overlapping wheel disc 12 of speed change, the last girder 18 and the following girder 10 of bicycle are the up concave type camber beam, fixedly one-level wheel disc 1 and secondary wheel disc 3 on the following girder 10, the small trochal disc that one-level wheel disc 1 chain-driving and secondary wheel disc 3 are coaxial, the overlapping wheel disc 12 of speed change on the big trochal disc chain-driving rear axle of secondary wheel disc 3, the formation two-stage is quickened, last girder 18 and following girder 10 tops are by the fixing vehicle seat chassis 5 of support beam 17, vehicle seat chassis slideway stationary adjustable vehicle seat 6, vehicle seat is a backrest type, and both are by adjusting handle location, the speed-changing mechanism 4 that gear shift fork 13 wire joints on the handlebar link to each other with axletree.

Last girder is by support 11 fixing hand wheel discs 2, and fixed handle 14 on the hand wheel disc, hand wheel disc chain-driving and one-level wheel disc 1 coaxial bonded assembly small trochal disc.

Another wheel of the coaxial connection of a side of back wheels of vehicle, two rear wheel tops are the compartment fixedly, forms speed change mountain region three-wheel vehicle.

There is rubber layer the runner outside of fixing small generators 8 on the bicycle front-axle beam, and this runner is pressed on the rim.

Narrate below in conjunction with drawings and Examples.

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

Fig. 2 has hand mountain bike structural representation of taking turns.

Fig. 3 is a three-wheel vehicle formula mountain bike structural representation.

With reference to Fig. 2 is an embodiment of the present utility model, two wheel shafts of this mountain bike connect wheel, the car back rest is car light 9 fixedly, the small generators that links to each other with car light 9 links to each other with the front truck beam, the hind axle partial fixing has speed-changing mechanism 4 and the overlapping wheel disc 12 of speed change of three wheel discs is arranged, the last girder 18 and the following girder 10 of bicycle are the up concave type camber beam, fixedly one-level wheel disc 1 and secondary wheel disc 3 on the following girder 10, the small trochal disc that one-level wheel disc 1 chain-driving and secondary wheel disc 3 are coaxial, transmitting ratio is 2:1, the overlapping wheel disc 12 of speed change on the big trochal disc chain-driving rear axle of secondary wheel disc 3, last girder 18 and following girder 10 tops are by the fixing vehicle seat chassis 5 of two support beams 17, vehicle seat chassis slideway stationary adjustable vehicle seat 6, and vehicle seat is a backrest type, both are by adjusting handle location, the speed-changing mechanism 4 of the gear shift fork 13 wire joint axletrees on the handlebar.

Girder is by two supports, 11 fixing hand wheel discs 2 on it, and fixed handle 14 on the hand wheel disc, hand wheel disc chain-driving and one-level wheel disc 1 coaxial bonded assembly small trochal disc.

This bicycle saddle is low, and vehicle body is stable, drive ride comfortable, the not fragile tire of its illumination equipment, but its hand speedup of taking turns, the speed of a motor vehicle of this car is higher.Maximum speed can reach 50 kilometers/hour.
