Description

F-w-d rear-axle steering bicycle

Technical field

The utility model relates to body-building apparatus and walking-replacing tool technical field, especially a kind of f-w-d rear-axle steering bicycle.

Background technology

The bicycle of prior art, mostly be back-wheel drive, front-wheel steering, gain knowledge according to human motion, keep the human body attitude of riding normally, pedal must be arranged at the preceding partially position of below-seat, the problem that exists is: this set pedal is to being provided with certain distance between the trailing wheel, be difficult for making vehicle to implement miniaturized design, for dwindle the wheelspan of front and back wheel as far as possible, invented the bicycle of f-w-d structure thereupon, can effectively shorten the wheelspan between the front and back wheel, but the problem of thereupon drawing is: work as Ackermann steer angle, pedal produces skew jointly with front-wheel, and the normal pedaling of human body is distorted, when angle of turn is big even can't finish normal pedaling, not only influences the traveling comfort that people ride and also have potential safety hazard.

Summary of the invention

The purpose of this utility model is a kind of f-w-d rear-axle steering bicycle that provides at the deficiencies in the prior art, and the utility model is convenient to vehicle enforcement miniaturized design, has comfortable, the safe characteristics of riding.

The concrete technical scheme that realizes the utility model purpose is:

A kind of f-w-d rear-axle steering bicycle, be characterized in that it comprises vehicle frame, steering hardware, handlebar and back vent, described vehicle frame is a beam-shaped member, its rear and front end is respectively equipped with preceding beam barrel, back beam barrel, the middle part is provided with vehicle seat, a side of beam barrel was fixed with front fork before the below of vehicle frame was positioned at, and the bottom of front fork is provided with front-wheel; Steering hardware is made up of steering front wheel, back wheel flutter and transport tape; Handlebar is provided with rotating shaft, and rotating shaft and preceding beam barrel are hinged, and steering front wheel is fixed in the end of rotating shaft; Back vent is hinged with the back beam barrel, and back wheel flutter is fixed in the back vent middle part, and the bottom of back vent is provided with trailing wheel; The transport tape intersection is around between steering front wheel, the back wheel flutter; Described front-wheel comprises wheel shaft, pedal, and wheel shaft is fixed in the center of front-wheel, and pedal is individually fixed in the wheel shaft two ends, and the wheel shaft both sides are provided with bearing, and front-wheel is connected in the bottom of front fork through bearing.

The utility model is convenient to vehicle enforcement miniaturized design, has comfortable, the safe characteristics of riding.

The specific embodiment

Consult Fig. 1, Fig. 2, Fig. 3, the utility model comprises vehicle frame 1, steering hardware 2, handlebar 3 and back vent 4, described vehicle frame 1 is a beam-shaped member, its rear and front end is respectively equipped with preceding beam barrel 11, back beam barrel 12, the middle part is provided with vehicle seat, a side of beam barrel 11 was fixed with front fork 13 before the below of vehicle frame 1 was positioned at, and the bottom of front fork 13 is provided with front-wheel 14; Steering hardware 2 is made up of steering front wheel 21, back wheel flutter 22 and transport tape 23; Handlebar 3 is provided with rotating shaft 31, and rotating shaft 31 and preceding beam barrel 11 are hinged, and steering front wheel 21 is fixed in the end of rotating shaft 31; Back vent 4 is hinged with back beam barrel 12, and back wheel flutter 22 is fixed in back vent 4 middle parts, and the bottom of back vent 4 is provided with trailing wheel 41; Transport tape 23 intersections are around between steering front wheel 21, the back wheel flutter 22; Described front-wheel 14 comprises wheel shaft 15, pedal 16, and wheel shaft 15 is fixed in the center of front-wheel 14, and pedal 16 is individually fixed in wheel shaft 15 two ends, and wheel shaft 15 both sides are provided with bearing 17, and front-wheel 14 is connected in the bottom of front fork 13 through bearing 17.

The utility model is to use like this: when riding: the human buttock is seated on the vehicle seat of vehicle frame 1, two hold handlebar 3, bipod and step down in respectively on two pedals 16, bipod alternately firmly, pedal 16 is rotated counterclockwise around wheel shaft 15, at this moment, wheel shaft 15, front-wheel 14 are positioned at the supporting of bearing 17 and rotate, and drive trailing wheel 41 by vehicle frame 1, back vent 4 vehicle is advanced; Work as Ackermann steer angle: apply a steering torque for handlebar 3, beam barrel 11 rotated before the rotating shaft 31 of handlebar 3 was positioned at, the steering front wheel 21 that is passed to steering hardware 2 through rotating shaft 31 forms a turning angle, by transport tape 23 be passed to the back wheel flutter 22, at this moment, back wheel flutter 22 turn over one identical with steering front wheel 21 corners, the turning angle that direction is opposite, and back wheel flutter 22 drives back vent 4 and is positioned at 12 rotations of back beam barrel, and back vent 4 drives trailing wheels 41 and rotates, and finishes the process of turn inside diameter.

The utility model can effectively reduce the wheelspan of front and back wheel, is beneficial to bicycle and implements micro-miniaturisation, interesting design; In the process of riding, work as Ackermann steer angle, because frame 1 does not produce skew with respect to front-wheel 14, pedal 16, people's physical efficiency keeps normal pedaling, has improved traveling comfort and safety that people ride.
