GEAR TRANSMISSION UNIT WITH A FORCED LUBRICATION SYSTEM INCLUDING ONE OR MORE LUBRICANT DISTRIBUTION BOXES

摘要

A gear transmission unit, particularly for a motor-vehicle, is provided with a forced lubrication system (3) for lubricating the rolling bearings (B1, B2, B3) and/or further inner components of the transmission unit. The unit is provided with one or more accessory elements in the form of lubricant distribution boxes (S). Each distribution box (S) has a hollow body rigidly connected to the casing (2) of the unit adjacent to a respective channel outlet (5A) which supplies a flow of lubricant under pressure. The hollow body defines an inner lubricant distribution chamber (C) and has an inlet (8) connected to the channel outlet (5A) and two or more outlets (8) connected to further conduits for channels (5B) or chambers, for supplying a flow of lubricant under pressure in parallel to various components to be lubricated inside the transmission casing (2).
