Four wheels of the utility model can touch the ground on an uneven road surface. A user can reverse the bicycle when the user rides the bicycle. The utility model is a novel four-wheel bicycle.

Description

Bearing circle is driven chain gear type quadricycle

The utility model relates to a kind of bicycle, especially a kind of quadricycle.

In the vehicle, existing quadricycle mainly is two trailing wheels of load on the rear cross shaft of vehicle frame, load front-wheel on the car fork of vehicle frame front end, load handlebar on the car breeches pipe, the vehicle frame middle part is equipped with pedal roulette and is connected the quadricycle that the flywheel on the hind axle is formed by chain.But existing quadricycle adopts the direct load front-wheel wheel of handlebar to stick, during use moment of torsion big, turn to effort.Especially four of car wheels are in operation and can not land simultaneously when meeting Uneven road, and unbalance stress is more fragile, and can not ride and move backward, and causes inconvenience to use.

The purpose of the utility model provides a kind of novel structure, turn to flexibly, four-wheel lands, can ride reversing, novel quadricycle easy to use.

For achieving the above object, the technical solution adopted in the utility model is: the welding slope tube is inserted and is connected bearing circle on vehicle frame, at the bottom of the bearing circle on the connection post load sprocket wheel connect the sprocket wheel of installing on the near front wheel wheel fork core pipe with chain, the wheel fork core pipe top of two front vehicle wheels is connected the steering hardware of the steering wheel type chain gear that consists of by intermediate rod; The wheel fork sleeve pipe of two front vehicle wheels is connected and fixed by sway bracing pipe, and weldering connects the V-arrangement pedestal on sway bracing pipe, the weldering connecting shaft holds in the base angle of pedestal, bearing carrier ring is loaded on the preceding shaft coupling of vehicle frame becomes V-arrangement hanging axis device, can make two front vehicle wheels is that rotate at the center with the hanging axis, makes also to land by four-wheel at uneven road surface; Also at the flywheel sidepiece of hind axle solid welding ratchet arranged side by side, and on hind axle the synchronizing clutch of installing and ratchet running-fit, the reversing gear that consists of, power-transfer clutch are realized riding by the clutch with the flywheel ratchet and are moveed backward or advance.

Because the steering hardware of steering wheel type chain gear and the hanging axis device of front-wheel V-arrangement have been adopted in the utility model design, and installed reverse clutch with the flywheel running-fit, prior art novel structure quite, steering hardware is laborsaving flexibly, can land at the uneven road surface four-wheel, stress equalization rideable again moved power-transfer clutch and is moveed backward, easy to use, be a kind of later-model quadricycle.

Below in conjunction with drawings and Examples the utility model is described in further detail.
