Abstract

The utility model relates to a bicycle, which comprises a bicycle cock, a front wheel and a tripod. The utility model is characterized in that the rear part of a bicycle frame is provided with a free wheel and small flywheels (4 and 6) which are coaxial with the free wheel; a shaft (10) is provided with a big flywheel and the small flywheel, and a shaft (11) is provided with the big flywheel and the small flywheel; both ends of the shaft (11) are provided with two wheels; the small flywheels and the big flywheels are driven through a chain. The bicycle of the utility model is a multiple-free wheel type sprocket drive fifth-wheel bicycle. A supporting wheel is added to cause the free wheel to independently run for enhancing the stability of the bicycle. Because the free wheel can store energy, the bicycle can be ridden in a labor saving way, and a rider can back the bicycle. The utility model not only has the advantage of no environmental pollution, but also has the advantages of strong stability, high speed, labor saving, etc.

Description

A kind of bicycle

The utility model relates to the vehicle, specifically a kind of bicycle.

Bicycle has had nearly bicentenary history so far from invention, people have carried out continuous transformation to bicycle, evolve to existing bicycle, the improvement of existing bicycle generally all is aspect the application and propulsion source of material, is seldom improving on the bicycle integral structure He on the stability.Existing bicycle less stable, a lot of bicycles are all relevant with the bicycle poor stability by the accident that automobile knocks down, hangs down.Also, often to fall a lot of falls and could learn because poor stability is also very difficult when begining to learn by bike.

The purpose of this utility model provides a good stability, and it is comfortable to ride, laborsaving, fireballing bicycle.

The utility model is achieved in that this bicycle comprises handlebar, front-wheel and spider, it is characterized in that the vehicle frame rear portion is provided with flywheel (3), what fly coaxial (16) therewith greatly flies (4 for a short time, 5,6), axle flies (7 greatly on (10), 8), for a short time fly (9), have greatly on the axle (11) and fly (12), wheel (13 is equipped with at these two ends, 14), for a short time fly (6) and preceding fly greatly (2) by chain gear, before fly greatly (2) coaxial with foot-operated line shaft (15), for a short time fly ((5) and big flywheel (7), for a short time fly (4) and fly (8) greatly by chain gear, for a short time fly (9) and fly (12) greatly by chain gear, axle (10,16) by the bearing supporting, bearing seat is fixed on the back vehicle frame (19).

Feature of the present utility model also is the preceding support wheel (17,18) that is provided with of wheel (13,14) on the vehicle frame of back.Be provided with backrest (22) behind the vehicle seat.

Bicycle of the present utility model is five wheel bicycles of a plurality of flywheel-type sprocket transmission, has increased support wheel, allows the flywheel independent operation, and bicycle stability is strengthened.Because flywheel energy stored energy, it is more laborsaving that bicycle is ridden, and the rider is moveed backward.The utlity model has outside the advantage free from environmental pollution, also have stability strong, advantage such as speed is fast, and is laborsaving.

Fig. 1 looks scheme drawing for master of the present utility model;

Fig. 2 is a schematic top plan view of the present utility model;

Fig. 3 is the schematic perspective view of this practical type.

Among the figure, the 1-tap, 2-flies greatly, the 3-flywheel, 4,5,6-flies for a short time, 7,8-flies greatly, 9-flies for a short time, the 10-axle, the 11-axle, 12-flies greatly, and 13, the 14-wheel, the 15-line shaft, the 16-axle, 17, the 18-support wheel, 19-vehicle frame, 20-spider, the 21-front-wheel, 22-backrest, 23-spring, 24-brake disc, the 25-first grade transmission chain, 26-second grade transmission chain, 27-bearing, 28-deciliter switch.

As shown in the figure, bicycle of the present utility model, comprise handlebar, front-wheel and spider, the vehicle frame rear portion is provided with flywheel 3, fly greatly therewith coaxial 16 fly 4 for a short time, 6, have on the axle 10 and fly 8 greatly, for a short time fly 9, have on the axle 11 and fly 12 greatly, for a short time fly 5, wheel 13 is equipped with at these two ends, 14, for a short time fly 6 with precedingly fly 2 greatly by chain gear, precedingly fly 2 coaxially greatly with foot-operated line shaft 15, fly 5 and fly 7 greatly for a short time, for a short time fly 4 with fly 8 by chain gear greatly, fly 7 greatly and be contained in the opposite side of riding line shaft, for a short time fly 9 with fly 12 by chain gear greatly, spools 10,16 by the bearing supporting, and bearing seat is fixed on the vehicle frame 19 of back.Be provided with

support wheel

17,18 on the back vehicle frame before the wheel 13,14.Be provided with backrest 22 behind the vehicle seat, between

support wheel

17,18 and

back wheel

13,14, have spring 23 to connect, play the shock-absorbing effect.Back brake can be contained on the axle 10 with the dish-like brake on the existing motor bike, and promptly brake disc 24.On foot-operated big flywheel and spider, adorn a deciliter switch 28, bicycle can be moveed backward.

Course of action: the power that the rider is pedaled bipod is up and down passed on the flywheel 3 by chain by flying 2 greatly, flywheel 3 passes to flying greatly on 8 of another root axle to power by chain by the miniature gears on the axle 4 again, this flies greatly by the miniature gears on the axle of controlling oneself power to be passed on the

trailing wheel

13,14 again, the promotion bicycle advances or retreats, refute a deciliter switch during reversing, make to fly 5 and fly 7 transmissions greatly for a short time, finish car.
