Abstract

The utility model provides a single wheel bicycle. Different from a bicycle with one wheel used for acrobatics performance, the utility model is provided with handle bars, a brake, a bell, a step and a goods shelf, and has a suitable variation ratio set for being used as a means of transportation. The single wheel bicycle is provided with only one wheel, the middle of a hub is provided with a through core axle, and both ends of the through core axle are respectively provided with a pinion respectively and internally connected with two pedal gear disks processed into internal gears, to form an inscribed gear transmission mechanism. The utility model has the advantages of safety, portability, little space occupation and practicality, and can be mastered by persons who can master the skills of ridding an ordinary bicycle.

Description

Single wheel bicycle
The utility model relates to a kind of unicycle, is a kind of later-model practical vehicle, can replace popular bicycle at present.
The existing bicycle that has only a wheel is only limited to acrobatics, and this car does not have handlebar, brake, bicycle bell, car ladder, and driving system can not be as the vehicle not as the suitable converter speed ratio of used for vehicle.
The purpose of this utility model, be for people provide a kind of safe, light, the little practical vehicle take up room.
Of the present utility model to the effect that such, the unicycle main body is made up of a wheel and a vehicle frame.Handlebar, brake, bicycle bell, car ladder, back shelf and the car that the gravity center of human body is moved forward and backward are housed on the vehicle frame to be sat.Wheel is made of rim, Tire ﹠ Tube, spoke, axle skin.Axle has in the middle of the skin one to connect mandrel, and respectively there is a miniature gears at two ends, connects respectively with in two pedal toothed discs that are processed into inner gear, constitutes the annulus transmission device.One end of axle skin is equipped with a ratchet that has hook tooth on the wheel card.Connect a miniature gears of adorning on the mandrel, just in time form a faying face with ratchet, ratchet just is contained on this miniature gears.So just formed a ratchet device.By connecting the sleeve mechanism that mandrel, miniature gears, pedal toothed disc, ratchet device are constituted, make unicycle finish a suitable converter speed ratio on the one hand, two pedals remain synchronous rotation about making on the one hand, the rider is scrunched stopping, pedal is relative with vehicle frame when static, and wheel still can roll forward along ground.
Figure elaborates below in conjunction with symbol.
Fig. 1 is the pedal toothed disc scheme drawing that is processed into inner gear.
Fig. 2 is the pedal toothed disc lateral plan that is processed into inner gear.
Fig. 3 is the vehicle frame scheme drawing.The 1st, the fluting that the installation shaft skin is used.The 2nd, the bearing of installation pedal crank shaft.The 3rd, the horizontal concrete chute that car is sat usefulness is installed.
Fig. 4 is along connecting the axial generalized section of mandrel.Wherein 4 is skins.The 5th, connect mandrel, be contained in the middle of the skin by ball 6.Axle skin 4 plays the effect of bearing with respect to connecting mandrel 5.The 7th, be fixed on a ratchet of skin right-hand member, have hook tooth on its wheel card.The 8th, be contained in the ratchet on the miniature gears 10.Miniature gears 9,10 is installed in the two ends that connect mandrel 5 respectively.11 and 12 is left and right sides pedal toothed discs, two annulus transmission devices about constituting with miniature gears 9,10 respectively.13, the 14th, left and right sides pedal crank.15, the 16th, left and right sides pedal crank shaft is contained in the bearing on the vehicle frame 23 by ball 17.18, the 19th, about two pedals.The working process of entire mechanism is such: scrunch pedal 18,19 forward, pedal toothed disc 11,12 just produces a torque and drives miniature gears 9,10 rotations.Ratchet 8 on the miniature gears 10 will insert in the ratchet 7 corresponding teeth.Ratchet is by an axle skin 4, and spoke 20,21 drives wheel 22 and rolls forward along ground.Axle skin 4 is contained in by ball 24 in the fluting of vehicle frame 23, and axle skin 4 has become turning cylinder again with respect to vehicle frame 23 like this.Stop to scrunch, wheel is because inertia can continue to roll forward along ground, and at this moment ratchet 8 is just deviate from from the hook tooth of original insertion, and left and right sides pedal 18,19 just can keep transfixion with respect to vehicle frame.From entire mechanism, also be not difficult to find out owing to connect the effect of mandrel, no matter on the left and right sides pedal 18,19 stressing conditions how, two pedal cranks 13,14 all can remain on the original mounted relative position, promptly on 180 ° the straight line.
Fig. 5 is the schematic rear view that the unicycle car is sat system.The 25th, H type bitubular support, tuning-fork type is sat pipe 26 and is loaded on wherein, and seat pipe 26 directly is pressed on the stage clip 27 of dress in the H type bitubular.The 28th, the nut of fastening H type bitubular support 25.The 29th, car is sat.
Fig. 6 is the unicycle scheme drawing.The 30th, handlebar.The 31st, bicycle bell.The 32nd, brake.The 33rd, the brake pull bar.The 34th, brake rubber block.The 35th, the car ladder.The 36th, car rack.
Illustrate that below in conjunction with Fig. 5, Fig. 6 this car seat system is auxiliary rider automatically regulating balance in riding how.At first, H type bitubular support 25 is contained in the horizontal concrete chute 3 by clamp nut 28.The height that this sample car is sat, H type bitubular support and horizontal angle α, human body is sat the stress point that acts on the vehicle frame by car, all can once adjust installation.When riding, human body weight acts on respectively on car seat and the handlebar, and gravity center of human body and axletree must could keep the balance of human body like this on the straight line perpendicular to the bicycle working direction.The technical ability of riding by the people can reach this balance fully, but has had the car of this particular design to sit, and just can make total balance of the body easier.Its action principle is such: the angle [alpha] that recedes during 25 installations of H type bitubular support, see Fig. 6.When the rider acts on pressure on the handlebar when increasing by two hands, human body just is that the center of circle produces a torque forward with the axletree, and at this moment rider's certainty be swerved the weight backward by the light of nature and be overcome this torque.Because human body weight is a definite value, after acting on the pressure increasing on the handlebar, the pressure that car is taken just must reduce, at this moment the stage clip 27 in the H type bitubular, will sit 29 a bit of δ of tuning-fork type seat pipe 26 ejections with having car, car is sat and is just produced a displacement x backward with respect to vehicle frame.The gravity center of human body is moved backward, play self-regulating effect.Otherwise reason also is the same.
