A powertrain assembly includes one or several electric motors, a gearbox comprising a gearbox housing, an axle comprising: an axle housing, movable parts inside axle housing, comprising a shaft for a wheel, a lubricating system comprising an axle lubricating device comprising an axle oil sump and a gearbox lubricating device comprising a gearbox oil sump inside the gearbox housing which is a dry sump having an oil storage area which is separate from said gearbox oil sump, a scavenge pump and a first duct configured to retrieve oil from gear box oil sump and to convey the retrieved oil up to the oil storage area, and a main pump and a second duct configured to convey oil from the storage oil area to lubricate the gears of the gearbox.

Electric powertrain for truck

The filter element includes a filter medium having an axis and forming a channel extending substantially axially, a first and a second end plate, each end plate covering one axial end of the filter medium and being sealingly mounted on the axial end whereby a liquid to be filtered can flow through the filter medium towards the channel and out of the filter element through an opening in fluid communication with the channel, or reversely. The filter element 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.

Filter element for a vehicle

A filter element is provided and includes a filter medium having an axial channel, end plates each sealingly covering one axial end of the filter medium, one end plate having an opening in fluid communication with the channel, a hole arranged on the liquid path, not on the filter medium, and a closing member which is arranged in the hole and which is configured: to prevent liquid from flowing through the hole when the liquid pressure upstream the closing member is below a predetermined threshold to open at the threshold, to allow liquid to flow through the hole, and, after it has been opened, to remain open. A method is provided for checking the suitability of a filter element, at first use after a filter element change. The method includes monitoring the liquid pressure at a point of the liquid circuit located outside of and near a port of a filter housing receiving the filter element, when an electrical pump of the liquid circuit is restarted for the first time, comparing the evolution of the monitored liquid pressure over time with a predetermined evolution over time of the liquid pressure at the point for a new reference filter element.

Filter and a method for checking the suitability of a filter element

A filter element includes: a filter medium having an axis and forming an axial channel; 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 central opening coaxial and in fluid communication with the channel; the filter element being designed to be placed in a filter housing for forming a liquid filtering device, whereby a liquid to be filtered can flow along a liquid path through the filter medium towards the channel and out of the filter element through the central opening. The filter element further includes further includes a detachable plug whose position can change from an attached position to a detached position. In the attached position the detachable plug is attached to an immobile portion of the filter element and seals the central opening, and in the detached position the detachable plug is detached from the immobile portion and is movable away from the central opening inside the channel and along the filter element axis to unseal the central opening.

The invention relates to a fuel supply system for an internal combustion engine comprising:&#x2014;a low pressure fuel pump ();&#x2014;a low pressure supply circuit () through which fuel is delivered by the low pressure pump () to one or several high pressure circuits (), said low pressure supply circuit () comprising at least one delivery connection () for delivering fuel to the high pressure circuit(s) ();&#x2014;a pressure regulator () through which excess fuel from the low pressure supply circuit () is discharged through the pressure regulator () in a pump return circuit () which is fluidically connected to an input () of the low pressure pump () without passing through the fuel tank (); characterized in that the pressure regulator () is located downstream of the delivery connection (), and in that a fuel derivation circuit () is fluidically connected to the low pressure fuel supply circuit () downstream of the at least one delivery connection () to the high pressure circuit(s) and upstream of the pressure regulator ().
