Patent ID: 8668611

Claim:
A dual-drive electric machine apparatus having a controllable epicyclic gear set (EG 101 ), comprising: an inner rotation part (EM 101 ) combined with an input wheel (W 101 ) of the epicyclic gear set (EG 101 ), an outer rotation part (EM 102 ) combined with a rocker arm (A 101 ) of the epicyclic gear set (EG 101 ), wherein: the inner rotation part (EM 101 ) and outer rotation part (EM 102 ) magnetically interact to form an electric machine (EM 100 ), the input wheel (W 101 ) engages at least one epicyclic wheel (W 103 ) rotatably mounted on the rocker arm (A 101 ), and the at least one epicyclic wheel (W 103 ) engages an output wheel (W 102 ), to form the epicyclic gear set (EG 101 ), said input wheel (W 101 ), output wheel (W 102 ), and epicyclic wheel (W 103 ) each including one of a bevel gear and a bevel friction wheel, and said input wheel (W 101 ) is mounted on a first rotation shaft (S 101 ) that forms a first input/output end, said output wheel (W 102 ) is mounted on a second rotation shaft (S 102 ) that forms a second input/output end, and said rocker arm (A 101 ) is combined with a sleeve-shaped rotation shaft (AS 101 ) that surrounds and is rotatable relative to at least one of said first rotation shaft (S 101 ) and said second rotation shaft (S 102 ) to form a third input/output end; and at least one of a first, second, and third controllable brake device (BK 101 , BK 102 , or BK 103 ) having a first side fixed to a housing (H 100 ) and action side that is fixed to at least one of the sleeve-shaped rotation shaft (AS 101 ) or rocker arm (A 101 ), the first rotation shaft (S 101 ), and the second rotation shaft (S 102 ) for controlling operation interactive operations between the first, second, and third input/output ends and the electric machine (EM 100 ) by locking or releasing said one of the sleeve-shaped rotation shaft (AS 101 ), first rotation shaft (S 101 ), and second rotation shaft (S 102 ).
