Described stator 2 is fixing with motor shaft 5 to be connected, and rotor 3 is rotationally connected with motor shaft 5 by bearing, described sun gear 6
Being contained on the rear end of rotor 3, planet carrier 9 is rotationally connected with motor shaft 5 by the second freewheel clutch 10, and described planetary gear 7 fills
On planet wheel spindle 7 ', planet wheel spindle 7 ' is fixedly connected on planet carrier 9, and ring gear 8 is fixed on the inwall of casing 1, the sun
Wheel 6 engages with planetary gear 7, and planetary gear 7 engages with ring gear 8；
The two ends of described casing 1 are respectively provided with drive end bearing bracket 13 and rear end cap 13 ', or one end of described casing 1 and front end
Lid 13 is made as one and the other end is fixed with rear end cap 13 ' and is connected, or one end of described casing 1 is fixing with drive end bearing bracket 13 even
Connect and the other end and rear end cap 13 ' are made as one；
The drive end bearing bracket 13 at casing 1 two ends and rear end cap 13 ' are stretched out outward respectively in the two ends of described motor shaft 5, described motor shaft 5
One end by bearing rotating support on drive end bearing bracket 13；
Also include that the first freewheel clutch 4, pull bar 11 and removable pin 14, described first freewheel clutch 4 are enclosed within motor shaft 5
Above and with rotor 3 fix and be connected, and between the first freewheel clutch 4 and motor shaft 5, have gap, described motor shaft 5 to have axially
Hole 5-1, pull bar 11 inserts in the axial hole 5-1 of motor shaft 5, and removable pin 14 is through the pin on the axial hole 5-1 hole wall of motor shaft 5
Hole 5-2 also fixing with the inner of pull bar 11 is connected, described removable pin 14 can offset with the keyway 4-1 of the first freewheel clutch 4 or
Separate；
Described planet carrier 9 is by bearing rotating support on rear end cap 13 ', and rear end cap 13 ' is stretched out in the end of planet carrier 9
Outward, the other end of described motor shaft 5 passes planet carrier 9.
As shown in Figure 1, 2, also include that flywheel 12, described flywheel 12 are positioned at the outside of rear end cap 13 ', and flywheel 12 is sleeved on
The end of planet carrier 9.
As shown in Figure 1, 2, for the ease of installing stator so that this utility model structure is more reasonable, also includes that stator props up
