Abstract

The utility model provides a bicycle force aid device, comprising an engine, a carburetor, a clutch, a driving gear, a controller, a tank, etc. The utility model is characterized in that the driving gear is fixed on a spoke of the front wheel by two semicircle clamps; a power output gear is fixed on a shaft of the engine; the gear engages with the driving gear to form the moving fit; the driving gear is driven to rotate by a power gear; the purpose of force aid to a bicycle can be achieved by utilizing the control of the controller and the clutch. The utility model has the advantages of simple structure, convenient installation, small size, compaction, safe riding, etc.

Description

Bicycle force aid device

The utility model relates to the bicycle driving device, particularly a kind of Accelarators for bicycles that travels with the engine drive front-wheel.

Common Accelarators for bicycles generally adopts pinch roller formula or sprocket-type, adopts two lines or multi-thread manipulation.The pinch roller formula has quick abrasion, and torsion is little, the shortcoming of tire patching trouble.Sprocket-type field engineering height, complexity, cost height add rather complicated two lines manipulation, and as modes such as throttle, clutches, this has kind of an in a rush sensation for common people.

The purpose of this utility model provides a kind of employing single line manipulation, simple in structure, easy to operate, the Accelarators for bicycles that utilizes the engine drive front-wheel to travel.

Technical solution of the present utility model is: Accelarators for bicycles is made of driving engine 1, carburettor 2, self-acting clutch 3, driven gear 5, control wire 13, effector 14, fuel tank 17.Its solution is that driven gear 5 is fixed on the front-wheel spoke 10 by two semicircle folders 6, fixes a power output gear 7 on the bearing of driving engine, make this take turns with spoke on the driven gear 5 composition running-fit that is interlocked.The upper end of driving engine is fixed on the side of front fork 9 by arm folder 11 in addition, and the lower end is fixed on the side of front wheel spindle 8 by negative thread bolt 4.

Advantage of the present utility model is: simple in structure, compact, install easily, single line manipulation, driving safety, low price etc.

Below in conjunction with accompanying drawing the utility model is illustrated.

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

Fig. 2 is the lateral plan of Fig. 1.

As shown in Figure 1, 2: this servo-unit is made up of driving engine 1, carburettor 2, self-acting clutch 3, negative thread bolt 4, driven gear 5, semicircle folder 6, power output gear 7, front wheel spindle 8, front fork 9, spoke 10, arm folder 11, oil pipe 12, control wire 13, effector 14, handlebar 15, bicycle bell 16, fuel tank 17, silencer 18.

Embodiment is: the upper end of driving engine is fixed on the side of front fork 9 with arm folder 11, and the lower end is fixed on a side of front wheel spindle 8 with negative thread bolt 4.In addition two semi-circular folders 6 are put in the front-wheel spoke 10, and be one just round, at the spoke place driven gear 5 is set, clamp 5 and 6 with screw.To be arranged on power gear 7 and driven gear 5 on the spoke on the generator shaft composition running-fit that is interlocked then, and rotate and reach power-assisted purpose with power gear 7 rotating band moving gears 5.

During the utility model operation, switch opens with fuel tank 17, effector on the handlebar 14 is pushed the D place, this moment, control wire 13 engaged self-acting clutch 3, the cylinder that the rotation of wheel just drives driving engine catches fire, ignition retard is returned to effector 14 between the B-C, and referring to stir effector 14 with mother again is may command carburettor 2, thus the speed of may command vehicle.When decontroling big mother and refer to, vehicle is because of the driving engine rotating speed automatic deceleration that slows down.When the speed of a motor vehicle slowed down or brake, self-acting clutch 3 will separate automatically, though vehicle stopped driving engine and can't stop working this moment.When open the throttle wide, clutch engagement, vehicle advances again.When car stops to need to stop working, effector 14 is pushed the A place, this moment, carburettor 2 was closed fully.After flame-out, during with foot-operated riding, this driving engine can not bring any resistance to the bicyclist, because the power-transfer clutch of this moment separates, so do not influence the alerting ability of car.

Claims

1, a kind of Accelarators for bicycles, constitute by driving engine 1, carburettor 2, self-acting clutch 3, driven gear 5, control wire 13, effector 14, fuel tank 17, it is characterized in that: driven gear 5 is fixed on the front-wheel spoke 10 by two semicircle folders 6, and on the axle of driving engine, be fixed with a power output gear 7, the composition running-fit that is interlocked of the driven gear 5 on this gear and the spoke 10.

2, Accelarators for bicycles according to claim 1 is characterized in that: the upper end of starting is fixed on the side of front fork 9 by arm folder 11, and the lower end is fixed on the front wheel spindle 8 by negative thread bolt 4.
