The use of metal particles inside the belt back (4) of a force transmission belt (1) serves primarily to protect the belt from overheating in transient temperatures of between 100° C. and approximately 400° C. which can occur during operation in motor vehicle engine compartments and in the heat radiation region of exhaust systems. To this end, the force transmission belt (1), which has a main body (3) made of at least one elastomeric material and having a sub-structure and a belt back (4), and a force transmission zone on the sub-structure, has lamella-type or flake-type particles made of metal, particularly aluminium, mixed into the elastomer at least in an outermost layer (5) of the belt back (4).
