The operation principle of embodiment 1 and embodiment 2：
For Fig. 1, when the outer ring of the 5th unilateral bearing 5 is fixed on wheel axis, the rotating shaft of internal speed-changing flower-drum 7 makees suitable
Hour hands can just rotate when rotating with motor car wheel, will not be rotated when doing rotate counterclockwise with motor car wheel.
The free wheel base and shell of internal speed-changing flower-drum 7 can only also make it is unidirectional rotate against, for Fig. 1,
When shell is motionless, free wheel base turns clockwise, free wheel base is in idling conditions；
When shell is motionless, free wheel base rotate counterclockwise when, free wheel base drives rotating shaft to turn clockwise；
When the free wheel base of internal speed-changing flower-drum 7 is motionless, shell rotate counterclockwise when, shell is in idling conditions；
When the free wheel base of internal speed-changing flower-drum 7 is motionless, shell turns clockwise, shell drives rotating shaft to turn clockwise.
The outer ring of the first unilateral bearing 1 and the outer ring of the 3rd unilateral bearing 2, sprocket wheel are separately fixed at due to connecting rod two ends
8 with the coaxial package of internal speed-changing flower-drum 7, while sprocket wheel 8 is fixedly connected with connecting rod 6, as shown in Figure 1.
When sprocket wheel 8 does rotate counterclockwise, connecting rod 6 drive the first unilateral bearing outer ring and the 3rd unilateral bearing it is outer
Circle does rotate counterclockwise, and the outer ring of the first unilateral bearing can only dally, and the outer ring of the 3rd unilateral bearing can drive inner ring to do
Rotate counterclockwise.
Because the inner ring of the first unilateral bearing 1 is fixed on the shell of internal speed-changing flower-drum 7, while the second unilateral bearing 2
Inner ring is also fixedly connected in the shell of internal speed-changing flower-drum 7, and the outer ring of the second unilateral bearing 2 is fixed on vehicle frame；When first unidirectional
When the outer ring of bearing 1 is dallied, the inner ring of the first unilateral bearing 1, the shell of internal speed-changing flower-drum 7 and the second unilateral bearing 2
Inner ring and outer ring are all motionless, function only as supporting the effect of vehicle frame；
Now, the outer ring of the 3rd unilateral bearing 3 can drive the inner ring of the 3rd unilateral bearing 3 to do rotate counterclockwise, and the 3rd is single
The free wheel base of internal speed-changing flower-drum 7 is driven to do rotate counterclockwise to the inner ring of bearing 3, the free wheel base of internal speed-changing flower-drum 7 drives interior become
The rotating shaft of fast flower-drum 7 turns clockwise, and the rotating shaft of internal speed-changing flower-drum 7 drives the inner ring of the 5th unilateral bearing 5 to do dextrorotation
Turn, when the inner ring of the 5th unilateral bearing 5 turns clockwise, the 5th unilateral bearing 5 is locked, the 5th unilateral bearing 5 it is interior
Circle drives the outer ring of the 5th unilateral bearing 5 to turn clockwise, and the outer ring of the 5th unilateral bearing 5 is fixed on axletree, and the 5th
The outer ring of unilateral bearing 5 is that band motor car wheel turns clockwise.
Meanwhile, the inner ring of the 3rd unilateral bearing 3 drives the inner ring of the 4th unilateral bearing 4 to do rotate counterclockwise, and the 4th is unidirectional
It is to be in idling conditions that the inner ring of bearing 4, which does rotate counterclockwise, will not drive the outer ring rotating of the 4th unilateral bearing 4, and the 4th is single
It is used only for supporting vehicle frame to the outer ring of bearing 4.
