{p_product_name} by {p_product_company}


The clutch cover is screwed to the flywheel and, when engaged, transmits the engine torque to the clutch disc via the housing, the tangential leaf springs and the pressure plate. For the dimensioning of the clutch cover, important factors such as the heat capacity of the pressure plate as well as the clamp load and release load of the diaphragm spring are considered. Diaphragm springs are belleville springs with integrated actuating levers, the diaphragm spring fingers. The housing and the pressure plate are connected by riveted leaf springs, the so-called tangential leaf springs. Due to their pretensioning, they lift the pressure plate when the clutch is released. The diaphragm spring is designed to ensure high operating comfort with its shape, material and well-tuned characteristics. The clamp load of the diaphragm spring determines the maximum transmittable engine torque as well as the necessary release load.
