Disc spring and coupling head layout for friction clutch

摘要

The coupling layout has a coupling cover (28) and a thrust plate (29) which is situated near the coupling cover. A wheel shaped disc spring (30) is connected to the coupling cover and is situated in between the thrust plate and the coupling cover. The disc spring has a compressed section (30a) and a number of supported sections (30c) which extend in the radial direction inwards from the compressed section. A number of pairs of lever sections (30b) extend radially inwards from the support sections. The gap between the pairs of levers is larger than the gap between each lever and the number of pairs of levers. A number of trapezoidal sections (30d) may be built in the disc spring, in between the support sections. Each lever section of the pairs of lever sections may be trapezoidal. There may be a number of lever sections in the gripping direction of both sides.
