A transmission arrangement for a vehicle, comprising:
- a first planetary gearset, configured to be drivingly connected to a first power unit upstream from the first planetary gearset, and shiftable between at least two gear states, comprising a direct gear state with a 1:1 speed ratio and a speed reduction gear state;
- a first secondary reduction gearset drivingly connected to the first planetary gearset and provided downstream the first planetary gearset;
- a second planetary gearset drivingly connected to the first secondary reduction gearset and provided downstream the first secondary reduction gearset, wherein the second planetary gearset is shiftable between at least two gear states, comprising a direct gear state with a 1:1 speed ratio and at least one speed reduction gear state;
- and
- at least one drive shaft drivingly connected to the second planetary gearset and provided downstream the second planetary gearset, wherein the at least one drive shaft and the second planetary gearset are coaxially arranged and configured to rotate with respect to a common rotational axis.
