Transmission arrangement for a vehicle

A transmission arrangement for a vehicle, comprising:

• an input component configured to be drivingly connected to an electric motor,
• a first planetary gear system comprising a first sun gearwheel, a first ring gearwheel, and a first planet carrier carrying a first set of planet gearwheels, wherein the first planet carrier is rotationally connected to an output component of the transmission arrangement,
• a crawler unit configured to selectively drivingly connect the first ring gearwheel to the output component, wherein the rotational connection of a first gear member of the crawler unit to a stationary member of the transmission arrangement is configured to cause the first ring gearwheel to rotate in an opposite direction compared to a rotational direction of the first planet carrier,
• a first sleeve movable between at least a first position, in which it rotationally connects the first sun gearwheel to the stationary member, and a second position, in which it rotationally connects the first sun gearwheel to the input component, and
• a second sleeve movable between at least a first position in which it is rotationally connected to the input component, and a second position in which it is rotationally connected to the stationary member, and
• a third sleeve movable between at least a first position in which it is rotationally connected to the first ring gearwheel, and a second position in which it is rotationally connected to the first gear member of the crawler unit,
• wherein the second and third sleeves are mutually coaxial, rotationally interconnected, and axially displaceable relative to one another.
