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).

A transmission arrangement for a hybrid drive of a motor vehicle, the transmission arrangement comprising:
- a change-speed transmission (G, Ga, Gb) with a drive output shaft (AW),
- a retarder (RE) with a retarder shaft (RW),
- an electric machine (EM) with a rotor shaft,
- a first gear ratio step (Ü1) between the drive output shaft (AW) and the retarder shaft (RW),
- the retarder (RE) being drivable via the first gear ratio step (Ü1), and
- the electric machine (EM) being arranged with its axis parallel to the retarder (RE) and being couplable to the retarder shaft (RW) by way of a second gear ratio step (Ü2).
A transmission arrangement for a hybrid drive of a utility vehicle, the transmission arrangement comprising:
- a change-speed transmission (G, Ga, Gb) having a drive output shaft (AW),
- a retarder (RE) having a retarder shaft (RW) defining an axis of the retarder,
- an electric machine (EM) having a rotor shaft (RO) defining an axis of the electric machine,
- a first gear ratio step (Ü1) between the drive output shaft (AW) and the retarder shaft (RW), and the retarder (RE) being driven via the first gear ratio step (Ü1), and
- the electric machine (EM) being arranged such that the axis of the electric machine is parallel to the axis of the retarder (RE), and the rotor shaft of the electric machine being couplable to the retarder shaft (RW) by way of a second gear ratio step (Ü2).
