A kind of unicycle
The utility model belongs to a kind of and singlely rides and by the manpower transportation that single-wheel constitutes, be specially a kind of unicycle.
Existing bicycle is two wheel constructions, on crossbeam, arrange handlebar and vehicle seat, vehicle seat is fastened on the crossbeam, the vehicle seat back is a luggage carrier, crossbeam is provided with axis, by the two wheels running of axis control setting before and after the crossbeam, therefore existing bicycle exists that complex structure, weight can't further alleviate, the cost height, makes trouble, deposits shortcoming such as inconvenience.
The purpose of this utility model be to overcome the deficiencies in the prior art and a kind of modern design be provided, deposit conveniently, cheap unicycle.
The purpose of this utility model is achieved in that by handlebar, the handlebar column of fixed installation handlebar, the vehicle seat column of fixed installation vehicle seat, the car crossbeam of handlebar column and vehicle seat column is installed respectively by bearing in the rear and front end, be arranged on hand braking on the handlebar, the braking tie rod, by braking brake rubber block hand braking and braking tie rod control wheel, car wooden fork upper end that is connected with the car crossbeam and the car wooden fork lower end that axis is arranged by bearing installation, crank of captiveing joint with axis and manpower drive pedal and form, on handlebar column and vehicle seat column, be fixed with pin respectively, between two pins, be provided with tie rod, be installed with driving wheel on the axis, driving wheel is connected with outer driven steamboat by outer chain, outer driven steamboat is packed in one of flower wheel adapter shaft, the flower wheel adapter shaft leans on bearing installation on car wooden fork lower end, flower wheel adapter shaft other end is fixed with interior driven bull wheel, the interior inner chain of driven bull wheel is connected with flywheel, after being fixedly linked, flywheel and wheel lean on bearing installation on axis, between car wooden fork lower end and axis upper end, divide four equalizer bars all around are installed, equalizer bar is up-small and down-big, lightness sensation in the upper and heaviness in the lower, about two lower curtates be connected in the wheel outer end.
The utlity model has modern design, deposit conveniently, cheap, features simple structure, ride advantages such as speed is brisk.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a lateral plan of the present utility model.
Fig. 3 is a drive configuration scheme drawing of the present utility model.
Fig. 4 is a steering structure scheme drawing of the present utility model.
Fig. 5 is a balanced structure scheme drawing of the present utility model.
As Fig. 1, shown in 2, the utility model is by handlebar 1, the handlebar column 2 of fixed installation handlebar, the vehicle seat column 8 of fixed installation vehicle seat 7, the car crossbeam 9 of handlebar column 2 and vehicle seat column 8 is installed respectively by bearing 26 in the rear and front end, be arranged on hand braking 3 on the handlebar, braking tie rod 4, by braking brake rubber block 11 hand braking and that braking tie rod control wheel 12 rotates, car wooden fork upper end 10 that is connected with the car crossbeam and the car wooden fork lower end 16 that axis 23 is installed by bearing 26, crank 25 of captiveing joint with axis and manpower drive pedal 21 and form
As shown in Figure 1, 2, 3, be installed with driving wheel 20 on the axis 23, driving wheel is connected with outer driven steamboat 14 by outer chain 18, outer driven steamboat 14 is packed in 15 1 of flower wheel adapter shafts, flower wheel adapter shaft 15 is installed on the car wooden fork lower end 16 by bearing 26, flower wheel adapter shaft 15 other ends are fixed with interior driven bull wheel 13, and interior driven bull wheel 13 inner chains 17 are connected with flywheel 19, and flywheel 19 is installed on the axis 23 by bearing 26 after being fixedly linked with wheel 12.Drive pedal 21, crank 25 by manpower, driving wheel 20 is rotated, drive outer driven steamboat 14 by outer chain 18, because of outer driven steamboat 14 is to be captiveed joint by flower wheel adapter shaft 15 with interior driven bull wheel 13, so interior driven bull wheel is rotation simultaneously also, and by interior chain 17 drive flywheels 19, because of flywheel 19 and wheel 12 are fixedly linked, so wheel 12 brings into operation.Drive configuration is to drive outer little flower wheel by big driving wheel, and outer little flower wheel becomes this process of bull wheel because of coaxial fixing with interior driven bull wheel so finished simultaneously by steamboat, interior driven bull wheel drives flywheel, finished process from large to small again, like this, the speed of a motor vehicle becomes fast very naturally advances.
Shown in Fig. 1,2,4, steering structure of the present utility model is rotated by handlebar rotating band motor-car seat, and finishes steering procedure, is fixed with pin 6 on handlebar column 2 and vehicle seat column 8 respectively, is provided with tie rod 5 between two pins.Handlebar column 2 and vehicle seat column 8 are installed in the forward and backward two ends of car crossbeam 9 respectively by bearing 26, form rotatable situation, handlebar 1 rotates, handlebar column 2 also rotates simultaneously, the pin 6 that is fixed on the handlebar column 2 will promote tie rod 5 in front and back, the promotion of tie rod 5 has driven pin 6 fixing on the vehicle seat column 8, vehicle seat 7 is rotated along with the effect of tie rod 5 pullings, the rotation of vehicle seat 7, must form cyclist's body's center of gravity, the center of gravity of the person has been formed slopely laying particular stress on of vehicle body and has finished steering procedure.
Shown in Fig. 1,2,5, wheelbarrow is to adopt wheel structure of travelling, and just becomes a key issue so take what method that it is not toppled in advancing.The utility model adopts the setting of anterior-posterior balance frame low center of gravity, finishes equilibrium process.Divide four equalizer bars 22 all around are installed between car wooden fork lower end 16 and axis 23 upper ends, equalizer bar 22 is up-small and down-big, lightness sensation in the upper and heaviness in the lower, about two lower curtates be connected in wheel 12 outer ends.Like this, if car tilts forward or backward, equalizer bar will make it steady because of the power that low center of gravity produces, and simultaneously, the effect of mud watt has been played in the connection of equalizer bar lower curtate again.And handlebar and vehicle seat are fixed on the car wooden fork upper end by the car crossbeam, and car is in advancing, and the people by the effect of lever and fulcrum, carries out gravity balance onboard artificially.
With holding the braking facility, form pulling force by braking tie rod 4, make on the braking brake rubber block and carry, be adjacent to wheel 12 inwalls, finish braking procedure.
