Fishplate bar on the axial direction of output shaft stretch, between the piston structure and piston connecting plate, the piston shell with
If piston shell between clutch base, described and being respectively equipped with dry bearing between the housing of output shaft, for the biography of improved force
It leads and plays a supporting role.
A kind of 10. power transmitting method using power transmission device as described in claim 1, it is characterised in that the side
Method is specific as follows：Planet pin and the institute between drive mechanism, planet carrier, drive mechanism and planet carrier are driven by driving mechanism
Double thickening planetary gears that the planet pin stated is equipped with rotate coaxially, since double thickening planetary gears are equipped with by surface
Second gear structure be meshed with the fixed second thickening gear ring so that described double thickening planetary gears are around the row
The axis rotation of star pin, since the first gear structure and first that described double thickening planetary gears are also equipped with by surface are thickening
Gear ring is meshed, so that the first thickening ring gear against rotation, and pass sequentially through the first thickening gear ring and drive the thickening planet tooth
Output shaft housing into rotation on the outside of roller box output shaft drives output shaft to rotate by exporting shaft housing, at this point, control piston structure
The clutch group being equipped between output shaft housing and the output shaft applies pressure so that clutch group and output shaft housing
Between the gap of several movable friction plates and clutch group and output shaft between several static friction pieces space change, and then
The output torque that output shaft is controlled to obtain, changes the output of output shaft.
