Abstract

A motor vehicle power transmission system whose rotating elements are all stopped upon stopping of the vehicle, and which comprises a lubricating device including an oil sump for storing a lubricating oil and a mechanically operated oil pump which is driven by one of the rotating elements to deliver the pressurized lubricating oil to predetermined lubricating points such as bevel gears of a differential gear device. The lubricating device has a substantially fluid-tight enclosure in which the lubricating points are disposed and which stores, in a substantially fluid-tight manner, a mass of the lubricating oil delivered from the oil pump.
