摘要

The clutch (4) has a closed coupling body formed from a clutch basket (6) and a coupler cover. Multiple clutch disks are received in the coupling body and positively coupled with a clutch core (9). The coupling body is formed with air inlets (18, 18') and air outlet (19, 19') as openings. The air inlets and the air outlets are displaced with respect to each other in a radial direction. Air guidance elements (21, 21', 21'') are provided at the clutch basket for radially directing an airflow from outside to inside. The air guidance elements are designed as guide vanes (22, 22', 22''). An independent claim is also included for a drive unit.
