Abstract: The present disclosure relates to a powertrain assembly for an industrial vehicle, including:



an axle housing receiving an output wheel,
a geartrain including:

a first input shaft,
a second input shaft,
an output shaft engaged with the output wheel,
an oil circulation pump configured to supply oil to gears of the geartrain,


a first electric motor, comprising a rotor coupled to the first input shaft of the geartrain, the rotor being supported by a first sealing and bearing assembly,
a second electric motor, comprising a rotor coupled to the second input shaft of the geartrain,
a first oil supply channel configured to supply some of the oil flow of the oil circulation pump to the first sealing and bearing assembly.

Abstract: The filter element includes a filter medium having an axis and forming a channel extending substantially axially, a first and a second end plates, each end plate covering one axial end of the filter medium and being sealingly mounted on the axial end, the first end plate having an opening in fluid communication with the channel, whereby a liquid to be filtered can flow through the filter medium towards the channel and out of the filter element through the opening, or reversely. The filter element further includes a protrusion fixedly secured to the first end plate and extending outwardly from the first end plate, the protrusion being substantially tubular and having a through hole in fluid communication with the first end plate opening, the protrusion forming a female coupling piece of a male-female connector, and a locking member capable of releasably locking a male coupling piece of the male-female connector in the female coupling piece.
