Conveniently to the understanding of the multi-functional Modified type bicycle of the liberation both hands that the present embodiment provides, below in conjunction with accompanying drawing, it is described in detail.
As shown in Fig. 1 and Fig. 4, the multi-functional Modified type bicycle entirety of these liberation both hands adopts plane triangle and spatial triangle configuration, and it has three wheels, and the angle of each rear wheel and perpendicular is between 5 ° ~ 10 °.Preferably, two trailing wheel 2 end faces become the angle of about 15 degree, the center of gravity so designing the multi-functional Modified type bicycle being reduction liberation both hands on the one hand improves the stationarity of riding, and another aspect is the span increasing wheel, thus the further stability improving vehicle body.The diameter of front-wheel 3 is smaller than the diameter of trailing wheel 2, and object makes front end vehicle frame 1 relatively shorter, on the one hand facilitates disabled person to get on or off the bus, and it is easier to make on the other hand to turn to.The front end of the multi-functional Modified type bicycle of liberation both hands is equipped with bicycle basket rear end and is provided with vehicle seat 4, facilitates the life of disabled person.
As shown in Figure 2, the matching problem of axle drive shaft and two wheels when considering that trailing wheel 2 drives, adopts two universal couplings 7 to connect two wheels, and realizes the angled transmission of two axletrees.Thus the rotation of trailing wheel 2 can be realized.Universal coupling 7 utilizes the device such as ball-type, cross bar to realize the axle Power output of different directions, for realize tween drive shaft 6 can side by side transmission of power on the left axle holding certain angle with tween drive shaft 6 and right axle, intend respectively adopting a universal coupling 7 at tween drive shaft 6 two ends.Two rotating shafts 8 are connected with vehicle frame 1 by bearing, and so tween drive shaft 6 just only has a degree of freedom rotated around its place axis.Tween drive shaft 6 is equipped with the multistage flying wheel with free-wheel clutch, and in addition, on tween drive shaft 6, fixed cover is equipped with reverse clutch 10, and this reverse clutch 10 is positioned at the right side of multistage flying wheel; This reverse clutch 10 comprises the card of the outer ring for locked described flywheel.The chuck of power-transfer clutch when the multi-functional Modified type bicycle of liberating both hands moves forward and the draw-in groove of multistage flying wheel right side disengage, only have when we need reversing, chuck just can be engaged with multistage flying wheel thus realize reverse and the car-backing function of tween drive shaft 6 under the pulling force of brake cable and the effect of spring thrust.
Steering hardware is wherein specially: being made into by vehicle seat 4 can low-angle (about 15 degree) wigwag motion, if centre of body weight changes make vehicle seat 4 planar tilt, the brake cable of its underpart and subsidiary driving device can be driven to realize the break-in of handlebar.Under the state applied without external force, handlebar and vehicle seat 4 can keep forward straight and level under the force of a spring respectively.Specific design is as follows: bottom vehicle seat 4, two ends, left and right are drawn two brake cable (first brake line 13 and the second brake cable 14) and are connected with the adjust bar two ends, direction of front-wheel crotch respectively, two brake cable crusts are fixed on vehicle frame 1, tighten brake cable with four springs, the multi-functional Modified type bicycle handlebar of liberation both hands and vehicle seat 4 can be automatically reset when applying without external force.Because people's health when riding the multi-functional Modified type bicycle of liberation both hands can not keep absolute level, that is center of gravity can often have a small amount of skew, at this moment the transmission sensitieness having debugged vehicle seat 4 and handlebar is just needed, should suitably reduce its sensitieness, make when not needing to turn, the fluctuation of person center of gravity trace, can not affect the direction of handlebar, thus makes more comfortable freedom and security of riding.
As shown in Figure 2, brake gear, backrest 5 is added in vehicle seat 4 rear end, thus enable disabled person sit more surely under the effect of health and backrest 5 friction force thus better have an effect, the backrest 5 of vehicle seat 4 is divided into fixed part and moving part, and moving part can do low-angle fixed-axis rotation, with reduction torsion spring on its axle, its lower end is connected with brake cable (the 3rd brake cable 12), rotation is changed and zoom into straight-line motion under the effect of motion amplification mechanism.When bicyclist needs brake, borrow power with pin, make dorsad pressured, moving part rotates to an angle backward, and make its transmission device strain brake cable, line shortens, and tension rear braking 9, realizes brake.When people leans on forward, the effect due to reduction torsion spring makes brake facing and steel ring disengage, and removes brake, makes car continue to move ahead.Preferably, front-wheel 3 is provided with Front brake; This device also comprises the 4th brake cable 15, and the two ends of the overcoat of described 4th brake cable 15 are separately fixed on described vehicle frame 1 and described vehicle seat 4, and the two ends of the interior lines of described 4th brake cable 15 are separately fixed at described backrest 5 and described Front brake.Adopt disc brake apparatus by front and back wheel 2, make brake safer.
Foot-operated Vehicular bell apparatus, due to upper limb disabled person hand inconvenience, cannot wake up by bicycle bell warning by hand when running into pedestrian, to this, we devise a use and ride loud foot-operated bicycle bell, realization and the manual bicycle bell of this function are similar, this foot-operated bicycle bell comprises: the shell be rotationally connected by gear wheel shaft and described vehicle frame 1, is sleeved on the sleeve on described gear wheel shaft, and described sleeve connects two respectively by spring hits son; The pedal be rotationally connected with described vehicle frame 1, one end of described pedal is connected with the arc rack with the gears meshing on described gear wheel shaft.When people is with foot-operated pressure pedal, circular-arc gear drives spring to hit sub rotation, and spring hits son and clashes into bicycle bell shell, thus sounding.
Front-wheel 3 is provided with the free-wheel clutch for limiting the reversing of described front-wheel 3, described free-wheel clutch comprises the ratchet be fixedly connected with described front-wheel 3; And be arranged on the ratchet matched on described vehicle frame 1 and with described ratchet.The multi-functional Modified type bicycle of liberation both hands also comprises the reversing pedal, the 5th brake cable and the 6th brake cable that are rotationally connected with vehicle frame 1, wherein, the two ends of the overcoat of described 5th brake cable are fixed on described vehicle frame 1, and the two ends of interior lines are fixedly connected with described reversing pedal and described ratchet respectively; The two ends of the overcoat of described 6th brake cable are separately fixed on described vehicle frame 1, and the two ends of interior lines are fixedly connected with described reversing pedal and described card respectively.When the multi-functional Modified type bicycle of liberating both hands moves forward, reverse clutch 10 on trailing wheel 2 axle and multistage flying wheel outer ring do not have sealed, when the multi-functional Modified type bicycle of namely liberating both hands moves forward by gravity, pedal with the multi-functional Modified type bicycle of existing liberation both hands is the same can not by with rotation, make pedal can accept the gravity of pin, strengthen comfort by bike.But because upper limb disabled person can not drag the multi-functional Modified type bicycle realization reversing of liberation both hands as normal person with hand, we devise a kind of device that can make the multi-functional Modified type bicycle reversing of liberation both hands for this reason.Power-transfer clutch is the mechanism of the control transmission on automobile, and it can control the transmission of power, and we utilize power-transfer clutch to realize the car-backing function of the multi-functional Modified type bicycle of liberation both hands for this reason.When needs are moveed backward, with the reversing pedal on foot-operated presser feet control panel, now You Liangge mechanism action simultaneously, one is that the upward slope protection voussoir of front-wheel 3 and skewed slot disengage under the pulling force effect of brake cable, and namely front-wheel 3 can rotate backward; Two is that the card of reverse clutch 10 and flywheel outer ring are locked, thus makes flywheel drive trailing wheel 2 to rotate backward, and the dynamic stretcher that realizes tramping with one's feet drives trailing wheel 2 thus the function of reversing.
In order to improve the speed of riding, the multi-functional Modified type bicycle of liberation both hands is ridden when the section of different gradient, the riding speed of its best is not identical, also different optimum speed requirements is had for different bicyclists, for convenience of and meet the requirement of numerous bicyclists to friction speed, we have added step by-step variable gear for this reason.Multistage flying wheel is a vitals in the multi-functional Modified type bicycle transmission system of liberation both hands, the multi-functional Modified type bicycle of these liberation both hands takes trailing wheel 2 drive pattern, multistage flying wheel is matched with universal coupling 7, realizes the multi-change speed of the multi-functional Modified type bicycle of liberation both hands.Multistage flying wheel is on the basis of single freewheel, and increase several flywheel sheets, the sprocket wheel on axis is combined, and forms various different transmission ratio, thus changes the speed of the multi-functional Modified type bicycle of liberation both hands.Flywheel principle of work: be when stepping forward to ride, chain 11 flywheel driven rotates forward, and at this moment flywheel internal tooth contains mutually with very heavy, and the turning effort of flywheel passes to fuse by very heavy, fuse drives rear axle and trailing wheel 2 to rotate, and the multi-functional Modified type bicycle of liberation both hands has just advanced.When stopping stepping stretcher, chain 11 and overcoat all non rotating, but trailing wheel 2 still drives fuse and very heavyly to rotate forward under effect of inertia, and at this moment flywheel internal tooth produces relative sliding, thus fuse is compressed in the notch of fuse, very heavyly have compressed again very heavy spring.When very heavy tooth top slides into tooth tip in flywheel, very heavy spring is compressed at most, then slightly to more advancing slip, is very heavyly bound on tooth root by very heavy spring, sends the sound of " clatter clatter ".Fuse rotates to be accelerated, and to slide on each flywheel internal tooth very heavy also very soon, sends the sound of " clatter clatter ".When oppositely stepping foot-operated, overcoat rotates backward, and can accelerate very heavy slip, makes " clatter clatter " sound obtain more rapid.
For realizing the arbitrary speed change request of user's energy, plan existing manual change-speed box and repack the change-speed box switching gear with pin into, before and after the change-speed box of flywheel be connected on foot control panel two independently foot controling pedals by brake cable, pin often presses once this pedal, the multi-functional Modified type bicycle speed change of liberation both hands once, until be transferred to the ideal velocity that bicyclist thinks.
In addition; in order to avoid occurring when going up a slope gliding; intend, at front-wheel 3, upward slope fender guard is installed; when the multi-functional Modified type bicycle that people rides liberation both hands goes up a slope; when people's leg soft unable cannot step again the liberation multi-functional Modified type bicycle of both hands or speed change of need stopping go up a slope time; the voussoir being arranged on the free-wheel clutch of front-wheel 3 is killed with the skewed slot automatically and on disk, front-wheel 3 cannot be rotated backward, ensure that safety when disabled person goes up a slope by bike.When needing reversing, step on the reversing pedal on control panel, voussoir is separated with disk just passable.
Can be found out by foregoing description; present embodiments provide a kind of user of making in the process of riding; health and both feet can be utilized to keep the balance of the multi-functional Modified type bicycle of liberating both hands; and realize left and right turn, lean against drag, clutch gear-shift reversing, foot-operated multi-change speed, foot-operated bicycle bell and the several functions such as protection that go up a slope; reach the effect can comfortablely ridden without arm, finally realize user's comfort feature by bike and freedom.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
