Abstract
In a transmission for an internal combustion engine including an oil sump and an oil pump operatively in communication with the oil sump, an oil reservoir is provided for receiving oil from the oil sump when the transmission is in direct drive and power is transmitted only through the main shaft of the transmission while the intermediate shaft is idling so that no friction is generated by the gears of the intermediate shaft being immersed in the oil of the oil sump.
Claims15
A transmission for an internal combustion engine including a housing, a main shaft and an intermediate shaft rotatably supported in said housing and supporting gears and an oil lubricating system disposed within said housing and comprising an oil sump, an oil pump with a main oil circuit for supplying oil to various components of said transmission and an oil reservoir arranged in said housing and being in operational communication with said oil pump.
A method of lubricating a transmission including an oil sump, an oil, an oil reservoir, and an oil pump for pumping the oil to lubricating points of the transmission, said method comprising the steps of lowering the oil level in said oil sump and transporting it to said reservoir when said transmission is in direct drive in which all the power is transmitted through the transmission by way of a transmission main shaft and lubricating the transmission main shaft by way of a dry sump circuit.
