Patent ID: 8621957

Claim:
A drive train for hybrid drives, including an internal combustion engine ( 102 ; 202 ), an electric machine ( 104 ; 204 ) connected to the internal combustion engine via a clutch ( 118 ; 218 ) and a transmission ( 106 ; 206 ) connected to the electric machine ( 104 ; 204 ), with a first spring and damping system ( 124 ; 224 ) being arranged between the internal combustion engine ( 102 ; 202 ) and the clutch ( 118 , 218 ), the electric machine ( 104 ; 204 ) being arranged on the transmission side of the clutch ( 118 ; 218 ) and the clutch ( 218 ) being arranged between the electric machine ( 104 ; 204 ) and the first spring and damping system ( 124 , 224 ), the clutch ( 118 , 218 ) having an input side ( 116 , 216 ) which is firmly connected for rotation with an output side of the spring and damping system ( 124 , 224 ), the spring and damping system ( 124 ; 224 ) including a centrifugal pendulum means ( 140 ; 240 ) for reducing rotational vibrations between the internal combustion engine and the electric machine ( 104 , 204 ), and a second spring and damping system ( 146 ; 246 ) being arranged between the electric machine ( 104 , 204 ) and the transmission ( 106 , 206 ) for reducing or eliminating rotational vibrations present between the electric machine and the transmission ( 106 , 206 ).
