Abstract
A lubrication arrangement for a bevel gear unit, such as a final drive (10-19) or a power takeoff unit (PTU), in the drive line of a vehicle has an external oil reservoir (25) on the unit to be lubricated. From this reservoir oil channels (27, 28) in the housing (11) of the unit lead to areas in the unit in special need of oil supply, such as to pinion bearings (16, 17) and to the area of gear engagement between pinion (10) and crown wheel (12). There is also a return channel (30) in the housing (11) of the unit for returning oil thrown out by the crown wheel (12) against the inside of the housing to the reservoir (25).
