Abstract

Multi-disk clutch connected downstream of a power split transmission consisting of a double clutch whose individual clutches rotate in opposite directions, the rotational-speed dependent axial forces being compensated on the shift piston, and has a valve which releases or blocks the flow of coolant to the disks and a return spring with an increasing spring characteristic line for calibrating the clutch.
