Double clutch with travel-controlled wear adjustment

As a result of wear to the clutch discs, the positions of the lever springs change, and this in turn alters the characteristic curves of the contact pressure and disengaging force. The consequence of this would be increased loads on the brushless DC motors of the electromechanical lever actuators.

In order to keep the position of the lever springs and therefore the contact pressure and disengaging force more or less constant, the double clutch has a travel-controlled wear adjustment mechanism.

It comprises the following main components: 

• Clutch cover with adjusting and sensing ramps
• Adjustment ramp ring for each partial clutch
• Ramp ring for each partial clutch
• Clamping springs, adjustment tension springs and adjustment roller springs for each partial clutch.
