Motor vehicle drive train, has clutch device with air cooling system assigned to compressed air source for active production of cooling air flow rate by compressed air, where clutch device is upstream of valve for controlling flow rate

摘要

The train (1) has a drive shaft (3) coupled with a transmission shaft (5) by a clutch device (9), where the clutch device has an air cooling system (13). The air cooling system is assigned to a compressed air source for the active production of a cooling air flow rate (15) by compressed air. The clutch device is upstream of a control valve (21) e.g. pressure control valve, on-off-valve and/or clocked operatable valve, for controlling the cooling air flow rate. An independent claim is also included for a method for cooling a clutch device of a motor vehicle drive train of a motor vehicle.
