Description
Affiliated technical field
The utility model relates to bicycle field.
Background technology
Existing two-wheeled cycle, due to stability reasons, for not learning the people who rode bicycle, particularly the elderly and child often can not normally ride, limited the crowd's of use scope, some old man is helpless to be only had with the large heavy general three-wheel vehicle again of volume and rides instead of walk and ride, very inconvenient.
Summary of the invention
The deficiency existing in order to overcome above-mentioned prior art, the utility model has designed a kind of tricycle with two front-wheels, and two front-wheels arranged side by side connect by front fork crossbeam, by turning to of stick control two front-wheels.
The concrete scheme that can realize the utility model above-mentioned purpose is:
A kind of tricycle with two front-wheels, comprise front-wheel, front brake, handle vertical pipe, chain gear combination, trailing wheel, back brake, vehicle frame, saddle composition, front-wheel is arranged to two wheels arranged side by side, the front fork crossbeam two ends that are arranged at its top are stretched in the upper end of two front forks on two front-wheels, handle vertical pipe inserts the centre of front fork crossbeam, front fork crossbeam middle part becomes T font to be fixedly connected with the front end of cross member of frame, handle vertical pipe inserts the centre of front fork crossbeam for being rotationally connected, front fork crossbeam two ends are stretched into for being rotationally connected in two front fork tops, stretching out end above front fork crossbeam at two front forks arranges respectively sprocket wheel A locate to arrange two sprocket wheel B on handle vertical pipe inserts front fork crossbeam, respectively sprocket wheel B is connected with sprocket wheel A with two chains, like this, turning to of double front wheel handled in rotation by handle vertical pipe simultaneously, in addition the end of stretching out above front fork crossbeam at two front forks of design arranges respectively crank A, on inserting front fork crossbeam, handle vertical pipe locates to arrange crank B, the structure respectively crank B and crank A being hinged with two connecting rods, play above-mentioned same purpose, design again in addition another double front wheel steering structure, handle vertical pipe middle part is rotationally connected with the front end of cross member of frame, and handle vertical pipe inserts the centre of front fork crossbeam for being fixedly connected with, and front fork crossbeam two ends are stretched into also for being fixedly connected with in two front fork tops.Like this, rotating handle vertical pipe can turn to front fork crossbeam together with double front wheel; Cross member of frame can also be arranged to stretching structure, and this structure forms by being no less than the mutual fit of two joints and telescopic outer tube, inner sleeve and catch gear; Due to the special construction of two front-wheels, front brake bottom bifurcated is connected on two front-wheels simultaneously to its control; Or front brake is incorporated on trailing wheel, become second brake gear of trailing wheel; In order to reduce size, two front-wheels can design littlely than trailing wheel.
The beneficial effects of the utility model are: the design's the tricycle with two front-wheels, and less than existing general manual tricycle volume, ride lighter, be applicable to can not riding the old man of ordinary bicycle or child and ride and ride instead of walk; As adopting the structure of the detachable disconnection of cross member of frame, two-wheel parts and rear wheel part before removable separation when needed, become ordinary bicycle by this rear wheel part with the component combination of other single front-wheel, is applicable to the use of difference needs in family.
