Abstract

The utility model relates to a single-wheel bicycle. The single-wheel bicycle is composed of a bicycle frame assembly, a wheel assembly, a braking mechanism, etc. A bicycle handle, a bicycle seat, etc. are arranged on the upper end of the bicycle frame assembly, and the wheel assembly is arranged on the lower end of the bicycle frame assembly. The braking mechanism is arranged between a bicycle frame and wheels. When the single-wheel bicycle is ridden, a left pedal and a right pedal are pedaled, a transmission mechanism is driven by a middle shaft to rotate, and the purposes of balance and walk can be achieved. Compared with the prior art, the single-wheel bicycle has the advantages of novel structural design, beautiful appearance, flexible use, handiness, small ground occupation area, convenient storage, etc. The single-wheel bicycle is a bicycle which integrates traffic and body-building into an integral body and is suitable for old people and young people.

Description

Unicycle

The utility model belongs to the bicycle mechanical design field, specifically is a kind of improvement of single wheel bicycle.

Existing single wheel bicycle is because structure design is limit, and no equalizing gear mostly is that the acrobat who is used for acrobatics team performs use, can not be used in people's daily life.

The purpose of this utility model is to overcome the deficiencies in the prior art part and a kind of structure design uniqueness, novelty are provided, and convenient parking uses unicycle freely.

The utility model is to realize like this, a kind of unicycle, comprise handlebar, vehicle frame, wheel set, braking mechanism, handlebar, vehicle seat, clothes hanger are equipped with in the upper end that it is characterized in that frame assembly, wheel set, support, bicycle transmission system are equipped with by wheel set, left and right pedal assembly in the lower end, and change gear mechanism is formed.The left and right pedal of bicycle, frame assembly are contained on the axis of wheel set, be contained in driving gear and dual gear engagement in the wheel set, dual gear meshes with variable gear again, and variable gear and shell tighten together, and shell links to each other with the outer ring by spoke.Driving system of the present utility model mainly is to link to each other by the pedal axis, driving driving gear and variable gear drives a vehicle, be meshing with each other by these gears, pedal and vehicle frame are connected as a single entity, above human body rides over when changeing before the pedal, will drive axis and driving gear, dual gear rotates simultaneously, to keep car body and total balance of the body.Brake gear is made up of bracket arm, brake backguy, return spring, brake, is contained between vehicle frame and the wheel.

Description of drawings:

Fig. 1 is the contour structures scheme drawing of unicycle;

Fig. 2 is the drive mechanism figure of unicycle.

Label declaration:

1, axis 2, key 3, driving gear 4, dual gear 5, bearing 6, variable gear cover 7, dual gear pedestal 8, screw 9, copper sheathing 10, little axle 11, inner casing 12, shell 13, screw 14, two-way shelves 15, bearing frame 16, bearing inner ring 17, overside 18, bearing 19, bolt 20, locknut 21, left foot are pedaled assembly 22, clamp nut 23, right pedal assembly 24, frame assembly 25, wheel set 26, transmission mechanism of bicycle 27, support 28, brake gear 29, vehicle seat 30, clothes hanger

Embodiment:

In conjunction with the accompanying drawings embodiment is done further detailed description, unicycle is improved on the basis of acrobatics single wheel cycle, is made up of frame assembly 24, wheel set 25, transmission mechanism of bicycle 26 etc.Handlebar, vehicle seat 29, clothes hanger 30 are equipped with in the upper end of frame assembly, lower end wheel-mounted assembly 25.Transmission mechanism of bicycle is contained in the central part of wheel set 25, link to each other with frame assembly 24 by axis 1, frame assembly 24 is welded by steel pipe, wheel set 25 is made up of cover tire, the inner tube of a tyre, spoke, steel ring etc., and brake gear is made up of bracket arm, brake backguy, return spring, brake wheel etc.The rider is pedaled left and right sides pedal makes axis 1 drive driving gear 3 rotations.Driving gear 3 is passed to dual gear 4 by gear mesh with power, dual gear 4 passes power and variable gear 6 again, variable gear 6 tightens together by screw 13 and shell 12, shell 12 and wheel set steel ring, inside and outside tire connects together by spoke, therefore variable gear 6 rotates and just drives whole wheel and rotate forward, reaches the purpose of travelling.When needing brake, hold tight bracket arm after, by the leverage of pull bar, the steel wire in the pulling brake backguy blocks cover tire the brake roller downwards, reaches the purpose of brake.When openhanded open bracket arm after, return spring 7 is provoked return with brake wheel, makes brake cable 8, bracket arm 2 returns.

The utility model compared with prior art have the structural design novelty, attractive in appearance, use flexibly, light and handy, Floor space is little, the advantage such as is convenient to deposit. Both having can be used as the vehicles, and can be used as again fitness equipment, is one Plant and integrate the suitable to people of all ages bicycle of traffic body-building.
