Abstract
The invention relates to a drive belt for a traction mechanism drive, having a radially externally arranged top layer () composed of a fiber-containing elastomer or of an elastomer comprising a fiber mesh, having a radially centrally arranged tension member layer () composed of a wound tension strand or a plurality of circumferentially oriented tension strands, and a radially internally arranged substructure () composed of an elastomer, wherein at least one wedge-shaped rib is integrally formed in the substructure (), a coating layer () composed of a circumferentially open fiber mesh being applied to the outer surfaces of said wedge-shaped rib. In order to prevent an abrupt change in the friction coefficient at the force-transmitting flanks of the ribs, provision is made for the circumferential ends () of the coating layer () and a parting joint (), which is filled by the elastomer of the substructure (), between said circumferential ends () of the coating layer () to be covered with a transverse strip () composed of a vulcanizable material, wherein said vulcanizable material has a reduced friction coefficient in relation to the elastomer of the substructure ().
