Abstract: A turbocompound assembly, in particular in the field of industrial vehicles, comprising a power turbine paired with the engine crankshaft, wherein the paring is carried out through said assembly, wherein the assembly comprises a differential arrangement, wherein the pinion of the power turbine defines a sun gear meshing into two or more planet gears, which in turn mesh into a ring gear coupled with the engine crankshaft.

Abstract: A pinion to be fitted on a turbine axis of an internal combustion engine, wherein said pinion is made in a single piece, equipped with an axial thread to screw it on said axis of the turbine, wherein an axial end of the pinion integrates/defines a disc spring.

Abstract: Assembling method of a pinion on a turbine axis of an internal combustion engine, wherein said pinion is made in a single piece having axial symmetry and equipped with an annular toothed part and with an axial part coaxial with said annular part and provided with a coaxial hole with a thread to screw the pinion on said axis of the turbine, wherein said thread has localized pitch variations.

Abstract: A chain transmission device for controlling the timing system of an internal combustion engine with two overhead camshafts, and having a first chain transmission from the drive shaft to an intermediate shaft, and a second chain transmission from the intermediate shaft to both the camshafts; and wherein the first transmission defines a step-down transmission ratio between the drive shaft and the intermediate shaft; the second transmission defines a step-down transmission ratio between the intermediate shaft and the camshafts; the chain of the second transmission has a pitch smaller than the pitch of the chain of the first transmission; and the intermediate shaft is defined by the drive shaft of a fuel pump of the engine.
