摘要： A mechanical system comprising a sump and at least one component to be lubricated or cooled arranged in the sump, the mechanical system comprising a lubricating fluid system provided with a lubricating fluid and a tank arranged in the sump. The tank is a leaking tank and is situated above said at least one component to be lubricated or cooled, the lubricating fluid flowing out of the tank by force of gravity, so as to reach said at least one component to be lubricated or cooled. The lubricating fluid system has at least one lift flow generator connected by at least one filling line to the tank and to at least one suction point present in a bottom of the sump. The lift flow generator fills the tank with the lubricating fluid present in said bottom at least during a starting phase.

摘要： The system comprises an oil pump driven in conjunction with an output shaft of a transmission, a first oil path for supplying oil discharged from the oil pump to a lubrication system of the transmission, a second oil path arranged in parallel with the first oil path to guide the oil from the oil pump to a heat exchanger, and a valve inserted on an upstream side of the heat exchanger in the second oil path. The valve opens at a first set pressure to conduct the oil from the oil pump to the second oil path. The oil is supplied to the first oil path in a low vehicle speed area below the first set pressure, so that oil supply necessary for the lubrication system can be ensured. The oil is supplied to the second oil path in a high vehicle speed area over the first set pressure.

摘要： In order to implement a reliable supply of lubricant to gear unit components during emergency or spinning operation of a gear unit, level control is provided in a lubricant sump of the gear unit as a function of the operating state by means of a control unit associated with a lubricant pump. During normal operation the level is adjusted to dry sump level. In contrast, the lubricant pump is switched off in emergency or spinning operation, so that a splash lubrication level is automatically achieved in the lubricant sump.
