Description

Carrier cycles

Technical field

A kind of carrier cycles belongs to the bicycle field.

Background technology

Existing bicycle luggage carrier places on the support body at vehicle seat rear, and its weak point is, shelf present position height, load-carrying capacity and poor stability, Chang Yin place the article binding on the shelf insecure and land and damage or lose.

Summary of the invention

The purpose of this utility model is, existing bicycle is improved, and provides front axle that a kind of shelf place bicycle to one section vehicle frame low side between the axis, load-carrying capacity is strong, good stability, and it is firm to put article, can avoid article lost, turn to carrier cycles flexibly.

The purpose of this utility model is realized by following technical scheme: a kind of carrier cycles, it comprises vehicle frame 1, handlebar 14, vehicle seat 13, be loaded on the front vehicle fork 4 in the vehicle frame 1 preceding standpipe 19, front-wheel 2 is equipped with by front axle 3 in lower end at front vehicle fork 4, in the central siphon 8 of vehicle frame 1, driving chain drum 9 is housed by axis 24, the trailing wheel 12 of band back sprocket wheel 10 is housed by rear axle 11 in the rear end of vehicle frame 1, its special character is: be fixed with by preceding to one section vehicle frame 1 between the axis 24 at front axle 3, rear profile tube 6,7, preceding, rear profile tube 6,7 bottom is fixed with the shelf 21 that underframe 5 is formed, on vehicle frame 1, be provided with by the handlebar 14 that places neutral tube 15, in the lower end of handlebar 14 driving pulley 16 is housed, on vehicle frame 1, be equipped with leading

sheave

17,18, on front vehicle fork 4, be equipped with by movable pulley 20, and driving pulley 16, leading

sheave

17,18, the steering hardware 25 that is connected to form by fly rope 23 by movable pulley 20.

The advantage applies of carrier cycles of the present utility model exists: because the axis that shelf place bicycle is to one section vehicle frame low side between the front axle, therefore, load-carrying capacity is strong, good stability, and it is firm to put article, can avoid article lost; Because steering hardware adopts pulley, rope connection structure, increased the manipulation distance of handlebar and front vehicle fork, make to one section vehicle frame low side between the front axle shelf to be set at axis and to become possibility, it is simple in structure, turns to flexible.

The specific embodiment

Utilize drawings and Examples that the utility model is further described below.

With reference to Fig. 1-4, carrier cycles has vehicle frame 1, handlebar 14, vehicle seat 13, front vehicle fork 4 is housed in the standpipe 19 before vehicle frame 1, by front axle 3 front-wheel 2 is housed, in the central siphon 8 of vehicle frame 1, driving chain drum 9 is housed by axis 24 in the lower end of front vehicle fork 4, the trailing wheel 12 of sprocket wheel 10 after band is equipped with by rear axle 11 in the rear end of vehicle frame 1 drives chain drum 9 and is connected with back sprocket wheel 10 by chain.Be fixed with shelf 21 at front axle 3 to one section vehicle frame 1 between the axis 24, shelf 21 are fixed with underframe 5 and are formed by forward and backward standpipe 6,7 in the bottom of forward and backward standpipe 6,7.On vehicle frame 1, be provided with steering hardware 25, steering hardware 25 is by the handlebar 14 that places neutral tube 15, in the lower end of handlebar 14 driving pulley 16 is housed, on vehicle frame 1, be equipped with leading

sheave

17,18, on front vehicle fork 4, be equipped with, and driving pulley 16, leading

sheave

17,18, connected to form by fly rope 23 by movable pulley 20 by movable pulley 20.Head end at fly rope 23 is connected with boomer 22.

The pulley of the utility model steering hardware 25, cord drive structure can substitute with known sprocket wheel, chain gear structure.Shelf 21 of the present utility model and steering hardware 25 also are applicable to that forward and backward putting on the motor-driven or battery-driven car of two-wheeled use.
