Hydraulic system for a gearbox comprising a starting clutch

Abstract

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.
