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.

Abstract: An internally ventilated disc brake comprising a brake disc, having two friction rings that are spaced apart by ribs. Air cooling channels are formed between the ribs with at least one heat dissipating element provided between the friction rings. The two friction rings and the heat dissipating element form an essentially integral molding so that the heat dissipating element is cast into the molding at least in certain areas. The heat dissipating element projects into at least one cooling air channel at least in certain areas and is disposed substantially in a parting plane of the molding, the parting plane extending parallel to the friction rings.

Abstract: An internally ventilated brake disk has two friction rings which are mutually connected by way of webs, ducts for conducting cooling air being formed between the webs and the two friction rings, and the webs extending in a curved manner between their end regions. End region of the webs, which point to an outer circumference region of the brake disk, are essentially radially aligned with respect to the brake disk and end region of the webs pointing to an inner circumference side of the brake disk are set at an angle of from 20° to 70°, preferably 30° to 60° C., with respect to a tangent ray applied to this point on the brake disk and pointing against the rotating direction of the brake disk.
