Device for a drivetrain of a hybrid vehicle, drivetrain and method for operating the same

摘要

A device for a drive train of a hybrid vehicle having a planetary gear set which comprises a carrier element, a sun gear element, and a ring gear element. A first element connects to a first input shaft of a first subtransmission of a transmission, and a second element connects to an electric machine of a hybrid drive. A first shift element which couples, in a first shift position, a third of the elements to a second input shaft of a second subtransmission of the transmission, to which an internal combustion engine can be coupled, and, in a second shift position, can be coupled to another element of the planetary gear set, and having a second shift element which couples the input shafts of both subtransmissions when engaged and separates the input shafts of both subtransmissions when disengaged.

1. A device, for a drive train of a hybrid vehicle, comprising:
a planetary gear set (8) comprising a carrier (9), a sun gear (10) and a ring gear (11), a first element (9, 10 or 11) of the planetary gear set serving for establishing a fixed connection to a first transmission input shaft (6) of a first subtransrnission (4) of a transmission (3), and a second element (9, 10 or 11) of the planetary gear set serving for establishing a fixed connection to a second transmission input shaft (7) of a second subtransmission (5) of the transmission (3), to which further an internal combustion engine (1) of a hybrid drive being connectable, an electric machine (2) of the hybrid drive being connectable, via a first shift position (A) of a first shift element (12), to a third element (9, 10 or 11) of the planetary gear set, and, via a second shift position (B) of the first shift element (12), being connectable to the first transmission input shaft (6) of the first subtransmission (4), and a second shift element (13), and when the second shift element (13) is engaged, both the first and the second transmission input shafts (6, 7) of the first and the second subtransmissions (4, 5) being coupled together, and when the second shift element (13) is disengaged, both of the first and the second transmission input shafts (6, 7) of the first and the second subtransmissions (4, 5) being separated from one another.
