Description
Technical field：
The utility model is related to technical field of bicycles, and in particular to moped.
Background technology：
Bicycle be it is a kind of with manpower trample pin pedal driving small-sized road on vehicle, be the common traffic of ordinary people
Instrument.During riding bicycle, due to pavement roughness, in the process of moving, people are sitting on vehicle seat inevitable people
Can produce and pitch, substantial amounts of gravitional force has been contained during pitching, due to without corresponding energy transmission
Device, these gravitional force are all wasted in vain, do not obtain answering, unfortunately.The bicycle of prior art, all leans on
Pedal carrys out drive sprocket rotation, and sprocket wheel is advanced by chain-driving bicycle, when being travelled on rough road surface, it is impossible to fill
Divide the part energy of the generation that pitched using human body.Therefore, improved for problems of the prior art.
Utility model content：
The technical problem that the utility model is solved：How bicycle to be produced because human body pitches in the process of moving
Raw energy is converted into the kinetic energy of front wheel.
In order to solve the above technical problems, the utility model provides following technical scheme：A kind of moped, including install
Leverage on vehicle body frame, the rear end of leverage is provided with vehicle seat, and the front end of leverage is provided with post core elevating mechanism,
Post core elevating mechanism activity is plugged in vehicle body frame, and the bottom of post core elevating mechanism is connected with the bottom of damping, damping
The rotating shaft of front-wheel is installed in the bottom of mechanism, and the damping is arranged on bogie, and bogie is articulated on vehicle body frame；Turn
To being connected with a chain on frame, the head end and tail end of chain with bogie elastic connection, chain be sequentially wrapped in the first sprocket wheel,
On middle rotary chain wheel, the second sprocket wheel, chain winds the first sprocket wheel and the direction of the second sprocket wheel is identical, and the first sprocket wheel and the second sprocket wheel are pacified
In the rotating shaft of front-wheel, the first sprocket wheel and the second sprocket wheel drive the rotating shaft to make single direction rotation respectively, and the first chain wheel drive turns
The direction of rotation of axle in contrast to the second sprocket wheel drive shaft direction of rotation conversely, middle rotary chain wheel be arranged on bogie on.
By above-mentioned technical proposal, people is sitting on vehicle seat, and bicycle running is jolting on road surface, and vehicle seat moves up and down, and drives
There is tilting in leverage, leverage drives the lifting of post core elevating mechanism, and post core elevating mechanism drives the bottom of damping
With respect to bogie lifting, the bottom of damping drives the rotating shaft of front-wheel to be lifted with respect to bogie.Turn when the rotating shaft of front-wheel is relative
Rise to frame, the head end of chain pulls whole chain to be moved to its head end direction, and the sprocket wheel of chain drive first and the second sprocket wheel revolve
Turn, the direction of rotation of the first sprocket wheel and the second sprocket wheel conversely, the first sprocket wheel drives the rotating shaft of front-wheel to rotate forward, the second sprocket wheel hair
Raw idle running；When the rotating shaft of front-wheel declines with respect to bogie, the tail end of chain pulls whole chain to be moved to its tail end direction, chain
The first sprocket wheel and the second sprocket wheel is driven to rotate, the direction of rotation of the first sprocket wheel and the second sprocket wheel is conversely, the second sprocket wheel drives front-wheel
Rotating shaft rotate forward, the first sprocket wheel dallies.
Or, by above-mentioned technical proposal, when the rotating shaft of front-wheel rises with respect to bogie, the tail end of chain pulls whole chain
Moved to its head end direction, the sprocket wheel of chain drive first and the second sprocket wheel rotate, the direction of rotation of the first sprocket wheel and the second sprocket wheel
Conversely, the first sprocket wheel drives the rotating shaft of front-wheel to rotate forward, the second sprocket wheel dallies；Under the rotating shaft of front-wheel is with respect to bogie
Drop, the head end of chain pulls whole chain to be moved to its tail end direction, and the sprocket wheel of chain drive first and the second sprocket wheel rotate, and first
Conversely, the second sprocket wheel drives the rotating shaft of front-wheel to rotate forward, the first sprocket wheel dallies for the direction of rotation of sprocket wheel and the second sprocket wheel.
The company that seat bar, rear end and the seat bar middle part that the leverage is connected on vehicle body frame crossbeam including front end are hinged
