GEAR TRANSMISSION UNIT WITH FORCED LUBRICATION SYSTEM

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). 一种特别是用于机动车的齿轮传动单元设有用于润滑滚动轴承(B1,B2,B3)和/或传动单元的另外的内部构件的强制润滑系统(3)。单元设有一个或多个呈润滑剂分配箱(S)的形式的辅助元件。每个分配箱(S)具有邻近供给处于压力下的润滑剂流的相应通道出口(5A)刚性地连接到单元的壳体(2)的中空本体。中空本体限定内部润滑剂分配腔(C
