Claim:
A dual-drive electric machine installed with an epicyclic gear type clutch, comprising: an electric machine (EM 100 ) having an inner rotation part (EM 101 ) and an outer rotation part (EM 102 ); a epicyclic gear set (EG 101 ) having an input wheel (W 101 ), an output wheel (W 102 ), and a rocker arm (A 101 ) on which is rotatably mounted at least one epicyclic wheel (W 103 ) rotatably engaged with the input wheel (W 101 ) and the output wheel (W 102 ), said rocker arm (A 101 ) being combined with the inner rotation part (EM 101 ) of the electric machine (EM 100 ); a first rotation shaft (S 101 ) connected to and rotatable with the input wheel (W 101 ); a second rotation shaft (S 102 ) connected to and rotatable with the output wheel (W 102 ); a sleeve type rotation shaft (AS 101 ) rotatably sleeved on the first rotation shaft (S 101 ), said sleeve type rotation shaft (AS 101 ) being combined with the outer rotation part (EM 102 ) of the electric machine (EM 100 ) such that the outer rotation part (EM 102 ) faces and magnetically interacts with the inner rotation part (EM 101 ); at least one controllable brake device (BK 101 , BK 102 , and/or BK 103 ); and a housing (H 100 ), wherein: the first rotation shaft (S 101 ) serves as a first output/input end of the dual-drive electric machine, the second rotation shaft (S 102 ) serves as a second output/input end of the dual-drive electric machine, and the sleeve type rotation shaft (AS 101 ) serves as a third output/input end of the dual-drive electric machine, a first action side of the at least one controllable brake device (BK 101 , BK 102 , and/or BK 103 ) is controllable to lock and release at least one of the first, second, and third output/input ends of the dual-drive electric machine to control transmission of rotational energy between the first rotation shaft (S 101 ), the second rotation shaft (S 102 ) and the sleeve type rotation shaft (AS 102 ), and thereby control interactive operations between the dual-drive electric machine (EM 100 ) and the first, second, and third output/input ends, and a second action side of the at least one controllable brake device (BK 101 , BK 102 , and/or BK 103 ) is connected to the housing (H 100 ).
