A powertrain for a vehicle, the powertrain comprising:
- a transmission, a propeller shaft and a differential gear, wherein the transmission comprises an output shaft which is drivingly connected or connectable to the propeller shaft, the propeller shaft is drivingly connected to the differential gear and the differential gear is configured to provide a driving torque to a respective half-shaft of a drive axle for driving the vehicle, and
- the transmission further comprising:
- an input shaft configured to be drivingly connected to a power unit;
- a planetary gearset comprising a sun gearwheel, one or more planet gearwheels, a planet gearwheel carrier and a planet ring gearwheel;
- a first gearset comprising a first gearwheel and a second gearwheel;
- a second gearset comprising a third gearwheel, a fourth gearwheel and a fifth gearwheel;
- wherein the first gearwheel is in driving connection with the second gearwheel, each one of the third and fourth gearwheels is in driving connection with the fifth gearwheel and wherein one of the third, fourth or fifth gearwheels is rotatably connectable or connected to the output shaft, and
- wherein the transmission further comprises at least two gear engaging devices which are configured to provide at least four selectable gear connections, comprising:
- a first selectable gear connection in which the planetary gearset is internally locked;
- a second selectable gear connection in which the planet gearwheel carrier is rotatably connected to the third gearwheel;
- a third selectable gear connection in which the planet ring gearwheel is drivingly connected to the fourth gearwheel;
- and
- a fourth selectable gear connection in which the planet ring gearwheel is rotatably locked to a fixed member;
- wherein the planet ring gearwheel is rotatably connected or connectable to the first gearwheel and wherein a first gear engaging device of the at least two gear engaging devices is configured to be provided in a first gear engaging device first state where the first gear engaging device rotationally connects the second gearwheel to the fourth gearwheel and in a first gear engaging device second state where the first gear engaging device rotationally disconnects the second gearwheel from the fourth gearwheel, wherein the third selectable gear connection is provided by at least setting the first gear engaging device in the first gear engaging device first state, and
- wherein the planetary gearset is located on a first side of a first geometric sectional plane intersecting the differential gear and wherein at least one of the first and second gearsets is located on a second opposite side of the first geometric sectional plane.
