Abstract: The invention is directed to a drive belt of rubber or rubber-like plastic having a surface protection (5) which includes polyamide-containing textile reinforcement and/or polyester-containing textile reinforcement. On the outer side, a surface coating (6) of a friction-reducing material in a matrix of at least one elastic addition polymer is provided. For improved heat resistance with good protection against wear, the elastic addition polymer has less than 2% by weight based on the polymer of structural components —O—CxRy—O— with x=1-3 and y=0-6. The R in a structural component can be the same or can be different and is selected from hydrogen and/or carbon-containing groups.

Abstract: A flexurally elastic drive belt (1) has a cover layer (2), a reinforcement layer (3) formed of individual cords (4) and a substructure (5). The substructure can include ribs (6) and grooves (7). The drive belt is further provided with a textile overlay on the working side (8) thereof that is susceptible to wear. The textile overlay (10; section B of FIG. 1) of the drive belt (1) combines a very durable resistance to wear and a noise attenuation especially for wet noises. This is achieved in that the overlay has, in a state in advance of fabrication and vulcanization, an elongation at tear of at least 30% in the longitudinal direction and of at least 100% in the transverse direction and is made of a textile material including staple fibers in a proportion in terms of quantity of at least 30% by weight.

Abstract: The invention relates to V-ribbed belts (1) which have ribs (5) which run at least on a first side in the longitudinal direction of the V-ribbed belt and which are formed by thermoplastic shaping, and the first side has a layer composed of a textile warp-knit fabric (7) composed of two different yarns. In order to provide better noise reduction, the warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5 N/1000 dtex, based on 5% extension, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, based on 5% extension, wherein the first and the second yarn in each case form a coherent network, and the yarns are not twined around one another. V-ribbed belts can be formed effectively with an elastic warp-knit fabric of said type, whose extension is based not only on the construction of the knitted fabrics. It is surprising that the belts maintain the good noise properties both in the new state and also after a relatively long service life.

Abstract: An HNBR-based toothed rubber belt (10) with a glass, carbon and/or aramid cord reinforcement (5) has a modified tooth covering (6) made of polyamide 6.6 fabric having weft threads (64) entirely or partly replaced in the peripheral/longitudinal direction of the belt by yarns made of polyether ether ketone (PEEK), polyimide (PI) and/or meta-aramid (M-A) or modified with PEEK, PI and/or M-A.
