摘要： Each of at least two layers of a carcass reinforcement has a breaking force per unit width higher than 2250 daN/dm. The minimum strength per unit width, measured for an elongation of less than 10%, of a second layer of carcass reinforcement is strictly greater than a value equal to 20% of the minimum strength per unit width, measured for an elongation of less than 10%, of a first layer of carcass reinforcement. The reinforcing elements of the two layers of carcass reinforcement have a thread count of less than 750 tex. The elongation of the reinforcing elements of the second layer of carcass reinforcement is greater than 4% under a force of 20 daN, and the secant elastic modulus values under tension at 10% elongation, Mt, Mj, satisfy the relationship Mt/Mj≥1.

摘要： The tire has a load index that is at least 118 and two layers of reinforcing elements. Each of the layers has a breaking force per unit width that is higher than 2900 daN/dm. A minimum strength per unit width, measured for an elongation of less than 10%, of the second layer is greater than 20% of the minimum strength per unit width, measured for an elongation of less than 10%, of the first layer. The reinforcing elements of the first layer have a thread count that is higher than 300 tex. The reinforcing elements of the two layers have a thread count of less than 750 tex. The elongation of the reinforcing elements of the second layer are greater than 8% under a force of 20 daN and the secant elastic modulus values under tension at 10% elongation, Mt, Mj, satisfy the relationship Mt/Mj≥1.

摘要： A tire assembly includes an assemblage formed of first and second impregnated woven or knitted structures, a bearing structure, and at least one sacrificial holder. The first impregnated woven or knitted structure includes a first woven or knitted fabric and a first layer of a first polymeric composition. The second impregnated woven or knitted structure includes a second woven or knitted fabric and a second layer of a second polymeric composition. The bearing structure includes bearing elements connecting the first and second woven or knitted fabrics together. Each sacrificial holder is structured to hold temporarily the first and second impregnated structures in contact with each other, connecting the first and second woven or knitted fabrics together. When the first and second impregnated woven or knitted structures are separated from each other, each sacrificial holder breaks before any breakage of the bearing elements.

摘要： A process is provided for manufacturing a tire assemblage that includes a first woven or knitted fabric including first threadlike elements, a second woven or knitted fabric including second threadlike elements, and a bearing structure including bearing elements connecting the first and second woven or knitted fabric together. The process includes coating each first threadlike element with a layer of a first adhesive composition and coating each second threadlike element with a layer of a second adhesive composition, heat treating each coated first threadlike element and each coated second threadlike element to crosslink the first adhesive composition and the second adhesive composition, and assembling the bearing elements with each heat-treated and coated first and second threadlike element to form part or all of the tire assemblage.

摘要： Bearing structure (6) has identical bearing elements (61) in tension outside contact patch (A) with the ground and in compression in the contact patch (A). Bearing elements (61) are filamentary and are connected to radially inner face (23) of radially outer structure of revolution (2) by radially outer fabric (71) and to radially outer face (33) of radially inner structure of revolution (3) by radially inner fabric (72), respectively. Furthermore, mean surface density D of bearing elements (61) per unit area of radially outer structure of revolution (2), expressed in 1/m2, is at least equal to (S/SE)*Z/(A*Fr), where S is area, in m2, of radially inner face (23) of radially outer structure of revolution (2), SE is connecting area, in m2, of radially outer fabric (71) with radially inner face (23) of radially outer structure of revolution (2), Z is nominal radial load, in N, A is area of contact with the ground, in m2, and Fr is the force at break, in N, of bearing element (61).

摘要： Tire-type device having bearing elements (7) within annular space (5) between inner and outer coaxial structures of revolution, the latter contacting the ground in contact patch (A). The bearing elements are independent in pairs and buckle under compression in contact patch (A). The smallest characteristic dimension E of section S of bearing element (7) is at most equal to 0.02 times the mean radial height H of the inner annular space (5), the surface density D of the bearing elements (7) per unit area of the radially outer structure of revolution, expressed in 1/m2, is at least equal to Z/(A*ΣFr/n), where Z is the nominal radial load, A is the area of contact with the ground, and ΣFr/n is the mean force at break under tension of the n bearing elements made to buckle under compression. Two sidewalls (8) close space (5), forming a closed cavity that can be pressurized.
