Abstract

Various embodiments of the present disclosure are directed to a drivetrain. In one example embodiment, a motor vehicle drivetrain is disclosed including a transmission arrangement for a motor vehicle with a primary engine. The transmission arrangement including a transmission input shaft which can be connected to the primary engine, and at least one transmission output shaft. The at least one transmission output shaft including a first summation planetary gear unit having primary and secondary first transmission input elements, and a first transmission output element, and a second summation planetary gear unit having primary and secondary second transmission input elements and a second transmission output element. The first transmission output element is connectable to the transmission output shaft via at least one first clutch and the second transmission output element is connectable to the transmission output shaft via at least one second clutch.

Drivetrain for a motor vehicle comprising:

a transmission arrangement for a motor vehicle with a primary engine, the transmission arrangement including
a transmission input shaft which can be connected or is connected to the primary engine,
a transmission output shaft;
a first summation planetary gear unit having primary and secondary first transmission input elements, and a first transmission output element;
and
a second summation planetary gear unit having primary and secondary second transmission input elements and a second transmission output element;
wherein the first transmission output element is connectable to the transmission output shaft via a first clutch and the second transmission output element is configured and arranged to be connected to the transmission output shaft via a second clutch,
wherein the primary first transmission input element of the first summation planetary gear is mechanically connected to the transmission input shaft via a primary first drive gear stage and the primary second transmission input element of the second summation planetary gear is mechanically connected to the transmission input shaft via a primary second drive gear stage, and
wherein the secondary first transmission input element of the first summation planetary gear is configured and arranged to be connected to a secondary engine via a first drive shaft and a control shaft, and the secondary second transmission element of the second summation planetary gear are configured and arranged to be connected to the secondary engine via a second drive shaft, a coupling gear and the control shaft, wherein the secondary engine is configured to drive the second drive shaft and the secondary second transmission input elements of the second summation planetary gear via the coupling gear synchronously to the secondary first transmission input element of the first summation planetary gear at the same or different speed and with the same or different direction of rotation.
