Abstract

A spring for a composite brake disk. The spring has a planar central region with a hole and two spring regions which are formed symmetrically to one another and which in each case on sides lying opposite one another adjoin the planar central region. The spring regions in each case have an arc and a spring arm. Preferably, the spring arms have in each case an end region with a rounded bearing surface. By such a spring being used, a simple construction of a composite brake disk is made possible, the occurrence of hotspots and the effect of thermal rubbing being as far as possible avoided. At the same time, a functionally appropriate fit of the spring is ensured, the load on the pot due to the bearing surface of the spring being kept extremely low.
