Hydraulic system for a gearbox comprising a starting clutch

摘要

A hydraulic system ( 1 ) for a transmission with a starter clutch is described. The hydraulic system ( 1 ) is designed to comprise a primary circuit ( 24 ) and a secondary circuit ( 5 ). A cooling system ( 9 ) for the starter clutch, a radiator ( 7 ) for hydraulic fluid and a lubricant supply ( 10 ) for the transmission are integrated into the secondary circuit ( 5 ), where the radiator ( 7 ) is arranged upstream from the cooling system ( 9 ) for the starter clutch. A volume flow of the hydraulic fluid through the radiator ( 7 ) can be limited by way of a controllable bypass line ( 11 ), which opens up into the secondary circuit ( 5 ) downstream from the radiator ( 7 ) and upstream from the cooling system ( 9 ) for the starter clutch.
