A device for a drive train of a hybrid vehicle having a planetary gear set (4) including a ring gear (9), a sun gear (10) and a carrier (8). A first element of these elements of the planetary gear set serves as the connection to a transmission input shaft (11) of a transmission (3) and a second element of these elements of the planetary gear set serves as the connection to an electric machine (2) of a hybrid drive. A clutch (5) and associated shift element (6) by which, in a first shift position (A), a third element of the planetary gear set can be coupled to an internal combustion engine (1) of the hybrid drive while in a second shift position (B), can be coupled to one of the other elements of the planetary gear set (4).
A device for a drive train of a hybrid vehicle, the device comprising:
A device for a drive train of a hybrid vehicle, having a planetary gear set (4) comprising three elements, the three elements of the planetary gear set being a ring gear (9), a sun gear (10) and a carrier (8), a first element of the three elements (8, 9, 10) of the planetary gear set is fixedly a coupled to a transmission input shaft (11) of a transmission (3), and a second element of the three elements (8, 9, 10) of the planetary gear set is fixedly coupled to an internal combustion engine (1) of a hybrid drive, and having a clutch (5), a shift element (6) by which, in a first shift position (A), an electric machine (2) of the hybrid drive is connected to a third element of the three elements (8, 9, 10) of the planetary gear set, and, in a second shift position (B), is connectable to the transmission input shaft (11) of the transmission (3).
A drive train of a hybrid vehicle in combination with device having a planetary gear set (4) comprising first, second and third elements, the third, the second and the first elements of the planetary gear set a comprising a ring gear (9), a sun gear (10) and a carrier (8),
A method of operating a device for a drive train of a hybrid vehicle, having a planetary gear set (4) comprising first, second and third elements, the third, the second and the first elements of the planetary gear set comprising a ring gear (9), a sun gear (10) and a carrier (8), the first element of the planetary gear set being fixedly attached to a clutch (5) and serving as a connection to a transmission input shaft (11) of the transmission (3), the second element of the planetary gear set serving as a connection to an electric machine (2) of a hybrid drive, the clutch (5) and a shift element (6) by which, in a first shift position o (A) of the shift element (6), the third element of the planetary gearset is connected to an internal combustion engine (1) of the hybrid drive, and, in a second shift position (B) of the shift element (6), being connected to one of the first and the second elements of the planetary gearset (4), the method comprising the steps of:
