Abstract

The utility model relates to a bicycle with front wheel driven, which is characterized in that handle bars at both sides of a bicycle faucet on the basis of the existing bicycle are lengthened by taking the faucet as a fulcrum; the other end is connected with a connecting rod arranged; the lower end of the connecting rod is eccentrically connected with a driving inner gear in a driving structure which is arranged at both ends of front wheel spindle; the left and the right handle bars move up and down, and drive the driving inner gear to move by the connecting rod to drive a front wheel to move. Both the front and the back wheels of the utility model can be used for driving when the utility model runs on flat ground or climbs slopes.

Description

The drivable bicycle of front-wheel

The utility model relates to the running vehicle field, relates in particular to the drivable bicycle of a kind of front-wheel.

Bicycle is the widely used a kind of main running vehicles in China town and country, in recent years, raising along with people's living standard, bicycle has all had no small variation in kind, style and configuration aspects, but have do not become at 2, any is that front-wheel passes through tap decision travel direction, on the other hand trailing wheel drives the flywheel that is fixed on the hind axle through chain becomes driving wheel, cyclist's two hands only buttress tap and grasp direction in process by bike, when climbing maybe need be given it the gun, cyclist's two hands were done nothing on quickening.

The purpose of this utility model is the deficiency that overcomes existing bicycle, provides a kind of except that trailing wheel can drive, the also drivable bicycle of front-wheel.

The purpose of this utility model is achieved through the following technical solutions: a kind of tap that comprises, front fork, front-wheel, big thick stick, vehicle seat, back vent, trailing wheel, be fixed on the flywheel on the trailing wheel rear drum, through chain bonded assembly large fluted disc and the drivable bicycle of front-wheel foot-operated and that rear deck seat constitutes, it is characterized in that front-wheel and front wheel spindle are fixed into one, fixed type bearing on the front wheel spindle of front-wheel both sides, fix passive flywheel on the front wheel spindle in the bearing outside, passive flywheel and initiatively inner gear engagement, initiatively in the inner gear the heart channel of Hang-Shaoyin axle be fixed on front fork bonded assembly steel part on, initiatively the eccentric part of inner gear outer end connects the lower end of connecting rod through axle, the handlebar end of the upper end of connecting rod and lengthening is hinged, and handlebar props up point articulated with tap.

The utility model by the staff application force left and right sides handlebar one on the other drivening rod do a garden arc motion on next, connecting rod drives initiatively internal tooth crop rotation conter clockwise circular movement by axle, initiatively inner gear drives passive flywheel and makes the conter clockwise circular movement, passive flywheel drives axle and makes the conter clockwise circular movement, reach the purpose that drives the front-wheel motion, the utility model can be given full play to the effect of staff, increase propulsive effort, help giving it the gun, especially when climbing by bike, act on simultaneously, alleviated the fatigue of shank by the hand leg.

Accompanying drawing 1 is the utility model front-wheel position master's TV structure scheme drawing;

Accompanying drawing 2 is a left side, a utility model front-wheel position TV structure scheme drawing;

In the accompanying drawing: the 1st, handlebar, the 2nd, connecting rod, the 3rd, active inner gear, the 4th, passive flywheel, the 5th, steel part, the 6th, front wheel spindle, the 7th, bearing, the 8th, front-wheel, the 9th, front fork, the 10th, axle, the 11st, eccentric shaft.

Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is on the basis of existing bicycle, is that fulcrum extends respectively with handlebar both sides handlebar 1 with the tap, the other end connects connecting rod 2, the lower end of connecting rod 2 connects the active inner gear 3 that is provided with through eccentric shaft 11, initiatively inner gear 3 fixedly adds on the steel part 5 that is welded in front fork 9 through axle 10, initiatively inner gear 3 meshes with the passive flywheel 4 that is fixed on front wheel spindle 6 outsides, also be provided with bearing 7 on the front wheel spindle 6 of passive flywheel 4 inboards, the outer end of bearing 7 is connected with front fork 9, and front wheel spindle 6 is captiveed joint with front-wheel 8.

Claims

1, a kind of tap that comprises, front fork, front-wheel, big thick stick, vehicle seat, back vent, trailing wheel, be fixed on the flywheel on the trailing wheel rear drum, through chain bonded assembly large fluted disc and the drivable bicycle of front-wheel foot-operated and that rear deck seat constitutes, it is characterized in that front-wheel and front wheel spindle are fixed into one, fixed type bearing on the front wheel spindle of front-wheel both sides, fix passive flywheel on the front wheel spindle in the bearing outside, the active inner gear engagement of passive flywheel and setting, initiatively in the inner gear the heart channel of Hang-Shaoyin axle be fixed on front fork bonded assembly steel part on, initiatively the eccentric part of inner gear outer end connects the lower end of connecting rod through axle, the handlebar end of the upper end of connecting rod and lengthening is hinged, and handlebar props up point articulated with tap.
