Patent ID: 8900082

Claim:
A dual-drive electric machine and planetary gear set assembly, comprising: a single electric machine (EM 100 ) having an inner rotation part (EM 101 ) and an outer rotation part (EM 102 ), the inner rotation part (EM 101 ) and outer rotation part (EM 102 ) being rotatable relative to each other, and the inner rotation part (EM 101 ) being situated inside the outer rotation part (EM 102 ); a planetary gear set (DG 101 ) having a sun wheel (W 101 ), an outer planetary wheel (W 102 ), at least one planetary wheel (W 103 ) rotatably engaged with the sun wheel (W 101 ) and the outer planetary wheel (W 102 ), a rocker arm (A 101 ) which is a carrier for said at least one planetary wheel (W 103 ), and a sleeve type rotation shaft combined with the outer planetary wheel (W 102 ); a first rotation shaft (S 101 ) combined with the sun wheel (W 101 ); a second rotation shaft (S 102 ); at least one controllable brake device (BK 101 , BK 102 , and/or BK 103 ); and a housing (H 100 ) of the planetary gear set (DG 101 ), wherein: the inner rotation part (EM 101 ) is combined with the rocker arm (A 101 ) and the second rotation shaft (S 102 ), the outer rotation part (EM 102 ) is combined with the outer planetary wheel (W 102 ) or sleeve type rotation shaft (AS 101 ), the first rotation shaft (S 101 ) serves as a first output/input end of the dual-drive electric machine and planetary gear set assembly, the second rotation shaft (S 102 ) serves as a second output/input end of the dual-drive electric machine and planetary gear set assembly, the sleeve type rotation shaft (AS 101 ) serves as a third output/input end of the dual-drive electric machine and planetary gear set assembly, 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 and planetary gear set assembly 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 101 ), 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 ).
