The invention relates to a toothed belt for driving a camshaft in high-performance engines having a vulcanized rubber compound body comprising a rubber component or a rubber component blend and mixing ingredients, wherein the base body comprises a cover layer as belt back, an embedded strength member and a base with a tooth-shaped power transmission zone. According to the invention, the rubber mixture, which is in particular peroxide-crosslinked, contains at least EPM or at least EPDM and also fibers as the rubber component (s). A blend, in particular an EPM / EPDM blend, can also be used. The fibers consist in particular of PVA or para-aramid, in particular in the form of short fibers, in particular again with the assistance of an adhesive system, for example based on a resorcinol-melamine resin. |
