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.
A system for lubricating a transmission for a vehicle, in which a lubricating oil is stored in a bottom of a transmission case containing the transmission, with gears of the transmission being partially immersed in the lubricating oil, said system comprising:
A system for lubricating a transmission for a vehicle, in which the transmission is contained in a case and includes gears partially immersed in lubricating oil stored in the case, and in which a fork shaft is used for gear shifting, said fork shaft being provided with an oil supply passage therein and ejecting holes for ejecting lubricating oil fed through said oil supply passage toward the gears of the transmission, said system comprising
