Abstract

The utility model relates to a one-wheel bicycle. The structure includes that a bicycle frame and a front fork are in a hinge connection, a handlebar is installed at the front end of the front fork, a safe wheel is installed at the lower end of the front fork, a bicycle seat is installed at the upper back end of the bicycle frame, a driving wheel is installed on the lower portion of the bicycle frame, and a transmission device is installed in the middle position of the driving wheel. An inner bearing, an outer bearing, a planetary gear frame, planetary gears, a center pinwheel, a fixed pinwheel, a driving wheel shaft, a middle shaft, a one-way clutch, a crank, pedals, a manual control rod, a connecting rod and a shock absorber constitute the transmission device in a mutual connection mode, and a transmission device protective cover is fixed outside the planetary gear frame.

Description

Unicycle

One, technical field

The utility model belongs to the technological improvement of traffic appliance, is specifically related to a kind of unicycle.

Two, background technology

Bicycle is a kind of simple, easy vehicle of capable, common, convenient, economy, environmental protection.Although it is regenerated through the innovation of nearly hundreds of years, totally see to differ from one another, and large multi-configuration item employing chain-drive structure, each defectiveness of in-use performance is unsatisfactory.

Three, summary of the invention

The purpose of this utility model is in order to improve the in-use performance of existing bicycle, provide a kind of laborsaving, fast, unicycle simple in structure, the main technical schemes of its solution is that vehicle frame and front fork are chain connection, handlebar is equipped with in the upper end of front fork, safety wheel is equipped with in the lower end, car Cuo is equipped with in the rear upper end of vehicle frame, drive wheel is housed below the vehicle frame, driving device is equipped with in the drive wheel center, driving device is by interior outer bearing, planetary gear carrier, planetary wheel, the center pinwheel, fixing pinwheel, live axle, axis, free-wheel clutch, crank, foot-operated, manual joystick, pipe link and bumper are connected to each other composition, and the planetary gear carrier outside is fixed wtih the driving device protective cover.

The utility model is rational in infrastructure, and is simple to operate, compare with the chain driving bicycle of conventional confguration have more laborsaving, quicker, characteristics more easily.

Four, description of drawings

Below in conjunction with accompanying drawing the utility model embodiment is elaborated.

Fig. 1 is integral structure schematic diagram of the present utility model.

Fig. 2 is the utility model driving device generalized section.

Fig. 3 is the utility model transmission wheel system structure schematic diagram.

Among the figure: 1. drive wheel 2. safety wheel 3. front forks 4. vehicle frames 5. handlebars 6. manual joysticks 7. pipe links 8. bumpers 9. vehicle seats 10. cranks 11. are ridden fixedly pinwheel 20. planetary wheels 21. free-wheel clutchs of 12. drivings device, 13. live axles, 14. outer bearings, 15. neck bearings, 16. axis, 17. planetary gear carriers, 18. center pinwheels 19..

Five, the specific embodiment

By a kind of unicycle shown in Fig. 1～3, that vehicle frame (4) and front fork (3) are consisted of chain connection, handlebar (5) is equipped with in the upper end of front fork, safety wheel (2) is equipped with in the lower end, car Cuo (9) is equipped with in the rear upper end of vehicle frame, drive wheel (1) is housed below the vehicle frame, driving device (12) is equipped with in the drive wheel center, driving device is by neck bearing (15), outer bearing (14), planetary gear carrier (17), planetary wheel (20), center pinwheel (18), fixing pinwheel (19), live axle (13), axis (16), free-wheel clutch (21), crank (10), foot-operated (11), manual joystick (6), pipe link (7) and bumper (8) are connected to each other composition, and the planetary gear carrier outside is fixed wtih the driving device protective cover.During use, the rider is sitting on the vehicle seat (9), and two are riding foot-operated (11), and two hand steered handlebars (5) are stepped on regard to dynamic square and promoted to move ahead as long as carry the underfooting.When carrying on the pin, foot-operated (11) that are enclosed within on the pin are also and then up, and crank this moment (10) rotates around axis (16), and free-wheel clutch (21) oppositely breaks away from, and axis is motionless.When stepping under the foot-operated quilt, the free-wheel clutch self-locking, power is passed to axis, when axis clockwise rotates, driving planetary gear carrier (17) and planetary wheel (20) rotates together, because of planetary wheel (20) and center pinwheel (18) and fixedly pinwheel (19) engagement, so when satellite gear (20) is prolonging fixedly pinwheel (19) rotation, just can drive drive wheel (1) rolling after live axle (13) rotates and move ahead.As long as cyclist's bipod ceaselessly up-and-down movement, unicycle just can continue to move ahead.If when in the process that moves ahead, going up a slope, rider's travel speed begins to reduce, and foot-operated speed is also along with correspondingly reducing, at this moment, the rider is as long as keep reducing the rear treadle frequency, simultaneously, pull at and turn round and stretch out the hand moving joystick (6), can increase kinetic moment, realize speed change, and the power after the speed change is apart from larger, and efficient is higher, and it is compared with existing bicycle has more laborsaving, quicker, more efficient, characteristics more easily.
