Abstract
The utility model provides an energy-saving rapid bicycle, which comprises a frame, a front wheel, back wheels, a handle, a saddle and pedals which are installed on the frame, wherein two large belt pulleys are parallel arranged above a pedal shaft on the frame, and are respectively connected together through a belt and two small belt pulleys which are installed parallel above a back wheel shaft of the frame. The number of the back wheels is two. The bicycle has large transmission ratio between the belt pulleys and large inertia of the belt pulleys, can ride in rapid speed and labor-saving, and has excellent stability after adopted the double back wheel structure, is difficult to fall down, and is convenient for using by children or aged people, or for being used to learn the bicycle.
Description
Technical field
The utility model provides a kind of improved bicycle.
Background technology
Present bicycle by vehicle frame, front-wheel, single trailing wheel, car pedal, handlebar etc. forms, the gap between preceding sprocket wheel and the back sprocket diameter is little, transmitting ratio is little, riding speed is slow, effort.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of energy-conservation quick bicycle, to improve riding speed and labor-saving effect.
The utility model is to realize like this, energy-conservation quick bicycle, it has vehicle frame, front-wheel, trailing wheel, handlebar, vehicle seat and car are installed on the vehicle frame to be pedaled, on described vehicle frame, car is pedaled and parallel above the axle two big belt pulleys is installed, and two big belt pulleys link together by two small belt pulleys of parallel installation above the hind axle of belt and vehicle frame respectively, and described trailing wheel has two.
Adopt the bicycle of said structure, the transmitting ratio between the belt pulley is big, and the inertia of belt pulley is big, and riding speed is fast, and is laborsaving, and adopts the double rear wheel structure, and good stability is difficult for skewing, and is convenient to child and the elderly and rides or be used for learning by bike.
Description of drawings
Fig. 1 is the scheme drawing of the utility model structure.
Fig. 2 is that the A of Fig. 1 is to partial view.
The specific embodiment
Below in conjunction with description of drawings concrete structure of the present utility model.
As shown in drawings, the energy-conservation quick bicycle of the utility model, it has vehicle frame 6, front-wheel 1, trailing wheel 15, handlebar 4, vehicle seat 8 and car are installed on the vehicle frame pedal 18, on described vehicle frame 6, car is pedaled axle 17 top parallel 19, two big belt pulleys of two big belt pulleys that are equipped with and is linked together by two small belt pulleys 14 of belt 16 with the hind axle 13 top parallel installations of vehicle frame respectively, and described trailing wheel 15 has two.
Two big belt belt wheels can be positioned at the bracing frame 6-6 of vehicle frame, the both sides of another bracing frame 6-7.Also can be positioned at two bracing frames, at this moment, the bracing frame of two big belt pulleys outside is inverted U-shaped.
The diameter of big belt pulley can be 42 centimetres, and the diameter of small belt pulley can be 7 centimetres, and the transmitting ratio of large and small belt pulley can be 6: 1, thereby has improved the speed of riding.Two belt-drivings are difficult for taking place skidding.
Spacing between two trailing wheels can be 10 centimetres, and is very near from getting, and turns round so flexibly, can not skew.
On described vehicle frame 6, the crossbearer 6-4 that car is pedaled between axle 17 and the hind axle 13 is the two sectional type structure, be installed together by screw collar 6-5 between two sections crossbearers, the brace 6-1 that is installed on the stand 6-3 also is the two sectional type structure, be installed together by another screw collar 6-2 between two sections braces, vertical rod, brace are hinged on vehicle frame top respectively.Screw collar is installed together by the outside thread on its negative thread and crossbearer or the brace, and the thread rotary orientation on two crossbearers or two braces is opposite.Rotate screw collar, make its drive two crossbearers or two braces near or from far, pedal spacing between axle and the hind axle thereby change car, belt is carried out stretching or loosens.Screw collar also can adopt plank frame, is convenient to rotate.
Rear portion at described vehicle frame 6 has been equipped with brake lever 12 by extension spring 11, and brake lever links together by the anterior brake handle of installing 5 of brake backguy 7 and vehicle frame.Pull brake lever, drive brake lever by the brake backguy and press close to trailing wheel, can realize brake.Behind the releasing of brake bar, brake lever is got back to original position under the effect of extension spring.
Can there be illuminating lamp 3 and dynamic loud-speaker 2 to be electrically connected by the storage battery 10 of lead 9 respectively with the vehicle frame rear portion in the front portion of vehicle frame.
The mode of riding of this bicycle is identical with existing bicycle.
