Far smaller than the input rotary inertia of speed changer and output rotary inertia.And it is furthermore preferred that damped rotation inertia is defeated less than power
Enter the output rotary inertia of the input rotary inertia and power output shaft 2 of axis 1.
In the present embodiment, rotary inertia and output rotary inertia are inputted in order to better improve, reduces damped rotation inertia,
It can also be nonmetallic using high strength and modulus using flywheel, frictional disk 32 is increased on power input shaft 1 and power output shaft 2
The modes such as material (such as carbon fiber), the radius of turn for reducing frictional disk 32 and buffer spring 62 are realized.
For the stepless transmission of the present embodiment during high-speed rotation, under the rotary inertia effect of differentiation, power is defeated
Enter axis 1 and power output shaft 2 keeps its dynamic speed stabilizing to rotate substantially, and frictional disk 32 then does high speed pulsation step-by-step movement rotation, and
And under the buffering of buffer spring 62, the revolving speed that power output shaft 2 obtains is equal to the consecutive mean revolving speed of frictional disk 32.
When arrangement of clutch 3 is closed, that is, when clutch block 31 be bonded with frictional disk 32, kinetic energy pass through input rotary inertia to
Buffer spring 62 shifts, and buffer spring 62 is exported to power output shaft 2 again, under the filter action of output rotary inertia, finally
Obtain revolving speed and the torque output of dynamic stability.It should be noted that the output revolving speed of power output shaft 2, by frictional disk 32
Consecutive mean revolving speed determines that mean speed is higher, and output revolving speed is higher.The output torque of power output shaft 2, by buffer spring 62
Dynamic compression amount determine, decrement is bigger, and output torque is higher.
