The invention concerns a gearbox of a vehicle (3), comprising at least a first input gear (111), a second input gear (112), a first output gear (121), a second output gear (122) and an engaging mechanism (4) able to connect one of the input gears (111, 112) with one of the output gears (121, 122), said engaging mechanism (4) comprising at least a first sleeve (131) and a second sleeve (132) both rotating coaxially around an axis X, said first sleeve (131) and said second sleeve (132) being rotationally linked with each other and capable of moving axially one relative to the other said along the axis X, said second sleeve (132) extending at least partly inside the first sleeve (131), said first sleeve (131) being able to engage with one of the input gears (111, 112) and said second sleeve (132) being able to engage with one of the output gears (121, 122), said first sleeve (131) and said second sleeve (132) both comprising an actuation area (131a, 132a) for moving axially the concerned sleeve (131, 132).

La présente invention concerne une sous-couche d'isolation phonique (2) en matériau isolant configurée pour prendre une position de transport dans laquelle la sous-couche d'isolation phonique (2) est enroulée sur elle-même et pour prendre une position d'application dans laquelle la sous-couche d'isolation phonique (2) est positionnée sur un plancher support (4), ladite sous-couche d'isolation phonique (2) comprenant une première face (8) et une deuxième face (10) opposée à la première face (8) et destinée à être en contact du plancher support (4), caractérisée en ce que ladite deuxième face (10) comprend des motifs (18) configurés pour former entre eux, dans la position d'application de la sous-couche d'isolation phonique (2), des cavités d'isolation phonique (19), la sous-couche d'isolation phonique (2) comprenant au moins une fente (20) débouchant dans au moins une des cavités d'isolation phonique (19) et s'étendant dans le matériau isolant en direction de la première face (8).

The invention concerns an electric axle comprising a housing, and, at least partly disposed inside the housing : - an electric motor (10) configured to deliver a first torque on a motor shaft (11) ; - a shiftable reduction gear assembly (330) comprising at least a first gearwheel (331) and a second gearwheel (335) coaxial with, and rotationally connectable to the motor shaft (11) ; - a planetary set (200) comprising two coaxial planetary gearsets, at least one member of the planetary set (200) being drivingly connected or connectable to the shiftable reduction gear assembly (330) ; - at least one driveshaft (90) configured to be drivingly connected to a wheel of the vehicle, the at least one driveshaft (90) being coaxial with, and receiving power from the planetary set (200).

A hydrogen combustion engine arrangement includes a source of hydrogen, an internal combustion engine having at least one cylinder having an inlet opening connected by first hydrogen supply line to the source of hydrogen and an outlet opening, an exhaust aftertreatment system connected by an exhaust line to the outlet opening of the at least one cylinder, the EATS including a selective catalytic reduction system (SCR), a combustion zone upstream of the SCR, the combustion zone being connected to the source of hydrogen by a second hydrogen supply line, and an arrangement for determining a temperature in the EATS, and a computer system configured to control delivery of hydrogen to the EATS in response to a signal from the temperature determining arrangement.
