Abstract

A transmission arrangement for a hybrid drive of a motor vehicle, in particular a utility vehicle, having change-speed transmission (G) with a drive output shaft (AW), a retarder (RE) with a retarder shaft (RW), an electric machine (EM) with a rotor shaft (RO) and a first gear ratio step (Ü1) between the drive output shaft (AW) and the retarder shaft (RW). The retarder (RE) is driven by way of the first gear ratio step (Ü1). The electric machine (EM) is arranged with its axis parallel to the retarder (RE) and can be coupled to the retarder shaft (RW) by way of a second gear ratio step (Ü2).
