Description
Technical field
The utility model belongs to the technological improvement of bicycle structure, and tool, which is stopped, is related to a kind of random speed change unicycle.
Background technology
Bicycle is a kind of simple, easy, economic, environmentally friendly vehicles, its maximum feature be it is flexible, conveniently, it is low
Carbon, body-building.The various types of bicycle of existing market production and sales, provides greatly side for people's trip
Just.But these bicycles majority vehicle type structures are complicated, and production cost is high, when using, speed is slow, labor intensive is big.
The content of the invention
The problem of existing for prior art, the purpose of this utility model is to provide a kind of simple to operate, rational in infrastructure,
A kind of random speed change unicycle easy to use.It is to improve transmission device on the basis of simple unicycle,
The general part for making it maximally utilise existing bicycle.The used technical scheme that solves the above problems is to include driving
Wheel, transmission device, vehicle frame, crank, safety wheel, foot-operated, foot brake hoof, car are sat and handrail.The center of the driving wheel leads to
Wheel shaft of overdriving is equipped with transmission device, and the two ends of live axle are equipped with crank, and centre is connected to vehicle frame, the fixed car in vehicle frame top
Sit, top is provided with handrail；The microcephaly of the crank is connected to ride, and rides front end outer side and dress in the middle of safety wheel, rear end is housed
There is foot brake hoof；Described transmission device includes live axle, one-way clutch, inner bearing, outer bearing, pinion frame, solid
Determine pinwheel, planetary gear, center pinwheel, wheel hub；Described live axle is placed in the center of driving wheel；It is described it is unidirectional from
Clutch is placed in crank major part and fastened with live axle；Described wheel hub is placed in two outsides of live axle, and passes through inner bearing
With live axle assembly connection；Described inner bearing, outer bearing, two inner sides for being respectively placed in wheel hub；Described pinion frame,
Fixed pinwheel, planetary gear, center pinwheel are placed in after combining between left side outer bearing and inner bearing.The utility model operation letter
Single, rational in infrastructure, convenient trip significantly reduces the unnecessary cumbersome part of bicycle.

Hold the planetary gear of 15. live axle, 16. one-way clutch, 17. outer bearing 18.
Embodiment
As the random speed change unicycle shown in Fig. 1-2, including driving wheel, transmission device, vehicle frame, crank, safety wheel,
Foot-operated, foot brake hoof, car are sat and handrail, and the center of the driving wheel 1 is equipped with transmission device 2 by live axle 15, drives
The two ends of the axis of a movable block are equipped with crank 4, and centre is connected to vehicle frame 3, and the fixed car in vehicle frame top sits 8, and top is provided with handrail 9；It is described
The microcephaly of crank is connected to foot-operated 6, rides front end outer side and safety wheel 5 is housed, rear end is equipped with service brake hoof car 7；Described transmission dress
Put including live axle 15, one-way clutch 16, inner bearing 14, outer bearing 17, pinion frame 11, fixed pinwheel 10, planet
Gear 18, center pinwheel 12, wheel hub 13；Described live axle 15 is placed in the center of driving wheel 1；Described one-way clutch
16 are placed in crank microcephaly, and are fastened with live axle, crank and it is foot-operated be both transmission device part, be also drive transmission device
In part, its speed change is different from drive gear speed change, and it is the change stroke speed change for changing pedal stroke；Described wheel hub 13
It is placed in the outside of live axle two；Described inner bearing 14, outer bearing 17, two inner sides for being respectively placed in wheel hub；Described planet tooth
Wheel carrier 11, fixed pinwheel 10, planetary gear 18, center pinwheel 12 are placed in after combining between left side outer bearing and inner bearing.Use
When cyclist be sitting on vehicle seat 8, two ride on foot-operated 2, when pin is above carried, and foot-operated 6 be enclosed on pin are also and then up, this
When crank 4 rotated around live axle 15, one-way clutch 16 reversely departs from, and live axle 15 is motionless.When being stepped under foot-operated 6,
The self-locking of one-way clutch 16, power is transmitted to live axle 15, when live axle 15 is rotated clockwise, and drives pinion frame 11
Rotated together with planetary gear 18.Because planetary gear train and center pinwheel 12, fixed pinwheel 10 are engaged, thus when planetary gear 18 along
Fixed pinwheel 10 can drive center pinwheel 12 to rotate when rotating, and center pinwheel 12 drives live axle just to make drive after rotating again
Driving wheel 1, which is rolled, to move ahead.As long as cyclist ceaselessly steps on downwards foot-operated, car body can steadily move ahead.To car body is being moved ahead
During brake, two ride and achieve that brake in foot-operated 2 rear positions.
