Abstract
A system for lubricating a transmission for a vehicle includes an auxiliary oil reservoir placed in the transmission case apart from transmission gears, an oil pump in the transmission case operated interlockingly with an output shaft of the transmission for pumping lubricating oil stored in the bottom of the case into the auxiliary oil reservoir, and a circulating means provided in the auxiliary oil reservoir for regulating the amount of oil circulated from the auxiliary oil reservoir into the transmission case, such that the amount of oil in the auxiliary oil reservoir is increased or decreased in accordance with a respective increase or decrease in the amount of oil discharged from the oil pump. This system allows the amount of lubricating oil stored in the transmission case to be reduced in accordance with an increase in vehicle speed, while ensuring the transmission is lubricated to a sufficient extent at all times by an oil splash scattered from the gears over the vehicle's full operating range, while avoiding attendant power loss and excessive rise in oil temperature which may otherwise result during high speed operation.
