Description
Technical field
This utility model relates to bicycle art, particularly relates to a kind of forerunner's rear steering bicycle.
Background technology
Existing bicycle, be all by hold handlebar carry out vehicle front-wheel steer control, when riding, health must lean forward with control direction, when realizing front-wheel steer, handlebar by front fork direct transmitting effect power to front-wheel.So owing to scrunching angle limits, bicyclist can only use upright sitting posture, stand or forward lean is ridden.
And recumbent bicycle of the prior art, handlebar and front fork are the most all integrated connection.Owing to taking half lying posture when human body is ridden, and the distance of handlebar distance gravity center of human body is farther out, because this person is difficult to control turning to of handlebar by arm, can only select to control turning to of handlebar by linkage, length yet with people's lower limb is greater than arm, in order to avoid vehicle body is long, pedal can be only positioned at the upper front of front-wheel.Such recumbent bicycle is not only difficult to control to turn to, and pedal also can affect the sight line of riding of bicyclist, thus causes safety problem.
Other front drive vehicle or front-wheel drive front-wheel steer, front-wheel drive can shorten transmission distance.One is that chain is discussed on vehicle frame, and chain reverses with the rotation of front fork, and this makes the working condition of chain deteriorate；Another kind is that whole drive system rotates together with front fork, but can disturb and turn to.The representative of this scheme is that middle part turns to " Boa Serpentis " series.And rear-axle steering is the above-mentioned Resolving probiems caused so that scrunch more efficiently.This just makes manufacture more smooth out the more efficient equipment of riding to be possibly realized.
Chinese patent CN20111007639.1 uses lower position steer direction handle, and connecting rod connects back vent, it is achieved rear-axle steering operates.Steering column jacket is at the afterbody of car, steering spindle and turn to back vent be integrated with steering column jacket, lower position steering handle, steering link collectively constitute steering mechanism, rear steering wheel is fixed on back vent, connect in the both sides of back vent and have left fork oscillating bearing and right fork oscillating bearing, both sides at steering handle, corresponding position with steering fork, also left handle oscillating bearing and right handle oscillating bearing have been correspond to, left fork oscillating bearing and right handle oscillating bearing are connected by connecting rod, right fork oscillating bearing and left handle oscillating bearing are connected by connecting rod, and common effect realization turns to.Which not only adds cost and also add the resistance turned to so that the physical demands that the activity of riding causes is the most excessive.
In view of this, for solving the technical problem that kinematic link is long, high expensive, resistance are excessive, it is provided that a kind of front-wheel is driving wheel, and trailing wheel is the bicycle of deflecting roller so that scrunch more efficiently.
Utility model content
The purpose of this utility model is to provide a kind of forerunner's rear steering bicycle.
The technical scheme that this utility model is provided by solving its technical problem is:
It is connected with front fork in the front end of vehicle frame, front fork end is provided with front-wheel, vehicle frame front end is transversely provided with spindle tube for placing spindle assemblies, crank and foot are pedaled, driving force is pedaled by foot, crank, sprocket wheel and chain or belt pulley and belt pass to front-wheel, drive bicycle, it is characterized in that back vent is integrated with handle vertical tube to be connected, vehicle frame rear end longitudinally sets column tube, place for back vent and handle vertical tube location, handle vertical tube is connected with handlebar, back vent and handle vertical tube are contained in frame-steering vertical tube, can pipe in flexible rotating, back vent securely links together with handlebar with the upper end of handle vertical tube, lower end is connected with rear axle, with trailing wheel centered by rear axle freely rotatable, composition steering mechanism.The appropriate location of vehicle frame is provided with back rest cushion, has lower back to do the strong point, it is simple to foot has an effect to scrunch more efficiently.Center of gravity is low, and windward side is little, therefore air resistance coefficient is low, more saves muscle power.Two handles of handlebar are positioned at the both sides of the back rest cushion of vehicle frame, it is simple to direction to control.There are one or two trailing wheels Rear Ends/Dropouts location.
When arranging a deflecting roller, trailing wheel is between back vent, and trailing wheel is connected with back vent by rear axle.
When arranging two deflecting rollers, two trailing wheels lay respectively in two prong of back vent, and two wheel shafts are connected with back vent so that bicycle running is more stablized with turning to and is easily manipulated.
Front-wheel drive can shorten transmission distance, backrest is taked to recline posture when human body is ridden, length yet with people's lower limb is greater than arm, in order to avoid vehicle body is long, described spindle tube is positioned at the front of front-wheel, for placing spindle assemblies, crank and pedal, driving force passes to front-wheel by pedal, crank, sprocket wheel and chain or belt pulley and belt, driving bicycle, therefore, pedal drives bicycle in front so that compact conformation, turn to flexibly.
Vehicle frame can be movable connection with the connection of front fork, is arranged between amortisseur.More comfortable so that ride.
Back vent two ends are arranged between amortisseur, and amortisseur can be installed in the prong of back vent in the way of sleeve.
Back vent two ends two trailing wheel has respective wheel shaft, it is to avoid turn to differential.
The beneficial effects of the utility model are: compact conformation of the present utility model, turn to flexibly, ride comfortable.This utility model is to solve kinematic link is long, high expensive, resistance are excessive technical problem, it is provided that a kind of front-wheel is driving wheel, and trailing wheel is the bicycle of deflecting roller, make to ride more comfortable, resistance is less, cost is lower.
