Definitions

• organic fillers other than carbon blacks mention may be made of functionalized polyvinyl organic fillers as described in applications WO-A-2006/069792 and WO-A-2006/069793, WO-A-2008/003434. and WO-A-2008/003435.
• an at least bifunctional coupling agent is used in a well-known manner to ensure a sufficient chemical and / or physical connection between the inorganic filler (surface of its particles) and the diene elastomer.
• organosilanes or at least bifunctional polyorganosiloxanes are used.
• TESPD abbreviated TESPD, of formula [(C 2 H 5 O) 3 Si (CH 2 ) 3 S] 2 .
• polysulfides in particular disulfides, trisulphides or tetrasulfides
• bis-monoethoxydimethylsilylpropyl tetrasulfide as described in the aforementioned patent application WO 02/083782 (or US Pat. No. 7,217,751).
• a process which can be used for the manufacture of such rubber compositions comprises, for example, and preferably the following steps: - incorporating in a mixer, to the diene elastomer or to the mixture of diene elastomers, the high density filler and the possible other filler reinforcing, thermomechanically kneading the whole, in one or more times, until a maximum temperature of between 130 ° C and 200 ° C;
• the first (non-productive) phase is carried out in a single thermomechanical step during which all the necessary constituents, the possible coating agents, are introduced into a suitable mixer such as a conventional internal mixer. or other complementary additives and other additives, with the exception of the crosslinking system.
• a suitable mixer such as a conventional internal mixer. or other complementary additives and other additives, with the exception of the crosslinking system.
• the low temperature crosslinking system is then incorporated, generally in an external mixer such as a roll mill; all is then mixed (productive phase) for a few minutes, for example between 5 and 15 min.
• the belt coating gum has, in the vulcanized state (ie, after curing), a density or density which is greater than 1.4 g / cm 3 , in particular between 1, 5 and 3. 0 g / cm 3 .
• Its secant modulus in extension (noted E10) is preferably less than 30 MPa, more preferably between 3 and 30 MPa, in particular in a range of 4 to 20 MPa.
• the rubber composition described above is therefore used, in the radial tire of the invention, as a coating gum of the crown reinforcement or belt disposed between the tread and the carcass reinforcement.
• the tire (1) schematically comprises a vertex (2) surmounted by a tread (3) (for simplicity, including a very simple sculpture), two inextensible beads (4) in which is anchored a frame carcass (6).
• the top (2), joined to said beads (4) by two sidewalls (5), is known per se reinforced by a crown reinforcement or "belt" (7) at least partly textile and / or metallic and radially external relative to the carcass reinforcement (6).
