Title: Lubrication ducts for differential - are used on road vehicle and have angled ducts sloping through bearings to bevel gears
Inventor: HAGER LUDWIG
IPC: B60K17/16
Filed: 1980-06-23
Abstract: Lubricating ducts for a differential allow the oil to be thrown upwards by the crown wheel and collected by radial wells or pockets (9) in the upper part of the housing. The oil drains into a collecting duct (11) on the outside of the main bevel bearings (2) and is pumped through the bearings to a distribution duct (12). From this angled ducts (13) lead to the bevel gears (5) for complete lubrication. The lubrication control uses the pumping action of the bevel bearings and requires only simple oil seals (14) to prevent loss of oil. Efficient lubrication of the bearings provides a long life and low wear.
