Patent number: 9631719Abstract: A transmission having a plurality of shifting elements which are selectively engaged and disengaged when a gearshift is carried out, and a plurality of gearsets which, depending on the shifting position of the shifting elements produce a defined transmission ratio, and a shifting oil system which supplies the shifting elements with oil in order to operate them and a cooling and lubricating oil system which supplies assemblies of the transmission with oil for cooling and/or lubricating. From the shifting oil provided by the shifting oil system, a partial stream of oil can be tapped off for cooling and/or lubricating the shifting elements, such that a quantity of cooling and lubricating oil that is or can be supplied by the cooling and lubricating oil system can be reduced to the quantity required for cooling and/or lubricating those assemblies of the transmission which do not contain the shifting elements.Type: GrantFiled: May 6, 2014Date of Patent: April 25, 2017Assignee: ZF Friedrichshafen AGInventors: Vyacheslav Brushkivskyy, Bernd Lutz
