An axle for a vehicle comprising: - a casing defining a space along a longitudinal axis and comprising a central portion and a pair of side portions connected to the central portion along said axis; - a pair of axle shafts (4, 5) partially housed in said space and comprising respective inner ends (4b, 5b) cooperating with a driveshaft configured to provide a drive torque to said axle shafts (4, 5); - respective wheel hubs carried in a rotationally free manner by said casing on said side portions and each cooperating with a respective outer end (4a, 5a) of said axle shafts (4, 5), said axle comprising a torque splitting assembly housed in said space and operatively interposed between said driveshaft and said axle shafts (4, 5) and configured to divide the torque coming from said driveshaft to the latter, characterized in that said axle shafts (4, 5) are connected to said torque splitting assembly in a slidable manner with respect to said axis, said axle comprising elastic means housed in said torque splitting assembly and configured to exert a force directed parallel to said axis against said axle shafts (4, 5) for keeping them in a first operative condition, said axle furthermore comprising actuator means interposed between each wheel hub and the respective axle shaft (4, 5) configured to selectively exert a force on the respective axle shaft (4, 5) higher than the force exerted by said elastic means for moving them from said first to a second operative condition, each axle shaft (4, 5) being provided with a first toothing and each wheel hub being provided with a second toothing made integrally with said wheel hub and with a transmission configured to be operatively interposed between said wheel hub and the respective axle shaft (4, 5), said first toothing meshing with said second toothing in said first operative condition and with said transmission in said second operative condition, wherein the transmission ratio between the respective axle shaft (4, 5) and the wheel hub obtained by means of said first and second toothings (33, 34) being different with respect to the transmission ratio between the respective axle shaft (4, 5) and the wheel hub obtained by means of said second toothing and said transmission. - a casing defining a space along a longitudinal axis and comprising a central portion and a pair of side portions connected to the central portion along said axis; - a pair of axle shafts (4, 5) partially housed in said space and comprising respective inner ends (4b, 5b) cooperating with a driveshaft configured to provide a drive torque to said axle shafts (4, 5); - respective wheel hubs carried in a rotationally free manner by said casing on said side portions and each cooperating with a respective outer end (4a, 5a) of said axle shafts (4, 5), said axle comprising a torque splitting assembly housed in said space and operatively interposed between said driveshaft and said axle shafts (4, 5) and configured to divide the torque coming from said driveshaft to the latter, characterized in that said axle shafts (4, 5) are connected to said torque splitting assembly in a slidable manner with respect to said axis, said axle comprising elastic means housed in said torque splitting assembly and configured to exert a force directed parallel to said axis against said axle shafts (4, 5) for keeping them in a first operative condition, said axle furthermore comprising actuator means interposed between each wheel hub and the respective axle shaft (4, 5) configured to selectively exert a force on the respective axle shaft (4, 5) higher than the force exerted by said elastic means for moving them from said first to a second operative condition, each axle shaft (4, 5) being provided with a first toothing and each wheel hub being provided with a second toothing made integrally with said wheel hub and with a transmission configured to be operatively interposed between said wheel hub and the respective axle shaft (4, 5), said first toothing meshing with said second toothing in said first operative condition and with said transmission in said second operative condition, wherein the transmission ratio between the respective axle shaft (4, 5) and the wheel hub obtained by means of said first and second toothings (33, 34) being different with respect to the transmission ratio between the respective axle shaft (4, 5) and the wheel hub obtained by means of said second toothing and said transmission.
