Abstract

The utility model relates to a bicycle which comprises a bicycle frame, and a front wheel, a rear wheel, a seat, handle bars and foot pedals which are arranged on the bicycle frame, wherein, a centre shaft of the foot pedals is supported by a bearing; a tooth disc on the centre shaft is sleeved on a circular disc through embedding; the circular disc is fixedly connected with the centre shaft; a topping lift baffle is arranged between the circular disc and the chain tooth disc; a small chain tooth disc is fixed on a corresponding rear wheel shaft. The centre shaft adopts the structure of the bearing supporting and the chain tooth discs sleeving with the circular disc, thereby the utility model has the advantages of good use effect, long service life and low maintenance cost; the structures of the handle bars and the seat are changed, thereby the structure is more reasonable and safe; the damping structure is adopted, thereby the utility model is more comfortable in use.

Description

Bicycle

Technical field

The utility model relates to a kind of bicycle.

Background technology

In prior art, bicycle comprises vehicle frame, the front and back wheel on the vehicle frame, vehicle seat, handlebar and pedal, and the pedal axis is supported by the sand bowl, and the Chang Yingang pearl is worn and torn and breaks down, also because of the flywheel structure complexity on the rear wheel, the maintenance maintenance inconvenience; Whole vehicle frame does not have shock attenuation unit, uses uncomfortable; Adopt intubate to be connected between vehicle seat and vehicle frame, handlebar and the vehicle frame, fixed effect is bad, and deflection easily causes fixing insecure.

The utility model content

The purpose of this utility model is to provide a kind of performance better bicycle at above-mentioned deficiency.

Technical solution of the present utility model is: bicycle comprises vehicle frame, the front and back wheel on the vehicle frame, vehicle seat, handlebar and pedal.The pedal axis is by bearings, and the chain chain wheel edge on the axis is enclosed within on the disk, and disk is captiveed joint with axis, and very heavy shelves are arranged between disk and the chain chain wheel, is fixed with the chain chain wheel on the corresponding rear vehicle shaft.Make and pedal pedal forward, drive the chain wheel rotation, the chain wheel of rotation drives gimmal chain wheel rotation on the rear wheel by chain, drives rear wheel at last and rotates, and realizes riding; Otherwise the chain chain wheel can dally.

Be connected with bumper between vehicle frame and the front and back wheel respectively, especially as frame of motorcycle bumper structure.

Adopt two sleeve pipes to be connected between handlebar and the vehicle frame, handlebar should not be crooked.

Adopt two sleeve pipes to be connected between vehicle seat and the vehicle frame, vehicle seat should not be crooked.

The utility model has the advantages that: axis adopts bearings and chain wheel and disk sleeve structure, and result of use is good, and the life-span is long, and the maintenance maintenance expense is low; Change handlebar, saddle construction, structure is reasonable more, safety; Adopt shock-damping structure, use more comfortable.

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

The specific embodiment

Bicycle comprises traditional vehicle frame, the front and back wheel on the vehicle frame, vehicle seat 9, handlebar 7 and pedal 1 (figure slightly).Referring to Fig. 1, the axis 2 of pedal 1 is supported by bearing 3, and chain chain wheel 4 edges on the axis 2 are enclosed within on the disk 5 and by bearing 11 bearing and turnings, disk 5 is captiveed joint with axis 2, very heavy shelves 6 are arranged between disk 5 and the chain chain wheel 4, be fixed with the gimmal chain wheel on the corresponding rear vehicle shaft.Pedal 1 realizes pedaling row or revolution between disk 5 and chain wheel 4.Be connected with bumper between vehicle frame and the front and back wheel respectively, structure is with the motorcycle vibration absorber structure, and it is more comfortable to ride seat.

Referring to Fig. 2, adopt two sleeve pipes 8 to be connected between handlebar 7 and the vehicle frame, reverse about having avoided, move up and down by jackscrew and fix.

Referring to Fig. 3, adopt two sleeve pipes 10 to be connected between vehicle seat 9 and the vehicle frame, reverse about having avoided, move up and down by jackscrew and fix.
