The invention relates to a powertrain for a vehicle. The powertrain comprising: at least one propulsion unit; a transmission connected to the at least one propulsion unit; a propeller shaft connected to the transmission, and at least one drive shaft of a rear axle, which at least one drive shaft is connected to the propeller shaft, so that the propeller shaft extends between the transmission and the at least one drive shaft. The at least one propulsion unit is arranged in a position between the transmission and the rear axle in a longitudinal direction of the vehicle. The invention also relates to a vehicle.

A rotor arrangement for an electric motor is disclosed. The rotor arrangement comprises a first rotor comprising a hollow cylinder and a cylindrical rotor stack shrink-fitted onto the hollow cylinder. The first rotor comprises a first end plate attached to a first end portion of the hollow cylinder. The rotor arrangement further comprises a rotor shaft comprising a first shaft member and a second shaft member arranged coaxially to the first shaft member. The first shaft member is connected to a connection portion of the first end plate. The rotor arrangement comprises a second rotor connected to the second shaft member. The present disclosure further relates to an electric propulsion motor arrangement, a vehicle, and a set of rotors for electric motors.

The present invention relates to an arrangement for cooling of an electrical machine. The electrical machine comprises a rotor rotatably arranged around a rotation axis, a stator including a stator winding arranged radially outside of the rotor, a housing enclosing the rotor and the stator, at least one drain hole configured to drain a cooling fluid from the housing, at least one spraying device configured to spray cooling fluid on the stator winding and a pump configured to pump cooling fluid to the spraying device. The arrangement comprises a control unit, which is configured, when the electrical machine is in operation, to receive information of the temperature in at least one position of the stator winding and to control the pump such that it pumps a flow rate of the cooling fluid to the spraying device, which is related to the estimated temperature of the stator winding.

A powered axle gear (I) for a motor vehicle. The axle gear can cope with large driving torques and at the same time be accommodated in an axle beam between the vehicle's tractive wheels. The axle gear has a gear housing () which accommodates a pinion () and a crownwheel () for transmission of rotary motion to the vehicle's powered axles (Y1, Y2). To this end, there are two bearings (), one on each side of the crownwheel () and the pinion's centerline (X), with a differential situated between the bearings (). The bearing () situated beyond both the crownwheel () and the pinion's centerline (X) has running round it an undivided bearing seat () provided with a portion running in the circumferential direction which protrudes over the pinion () towards the latter's centerline (X) in a configuration which at least partly overlaps the pinion (). The invention relates also to a motor vehicle with this axle gear.
