Assignee: ZF FRIEDRICHSHAFEN AG
Field: Mechanical elements (Mechanical engineering)
Classification: CPC F | IPC F

Claim 5:
6. The method of claim 1, wherein, when the friction-locking shift element (1) includes a wave spring (7), the pressure versus torque characteristic curve (6) has a further characteristic point, the further characteristic point being a reaction point (RP) at which the friction-locking shift element (1) switches from an elastic state into a rigid state as the wave spring (7) compresses,
wherein the pressure versus torque characteristic curve (6) includes the second characteristic curve range (6b) having the second functional dependence between the contact point (CP) and the reaction point (RP) and a third characteristic curve range (6c) after the reaction point (RP), the third characteristic curve range (6c) having a third functional dependence between the power transmission capacity and the actuating pressure.
