TYRE BEAD REINFORCEMENT COMPRISING DISCONTINUOUS REINFORCING ELEMENTS

摘要

includes additional reinforcement (9) in at least one bead, and this additional reinforcement is the length L0 composed of a plurality of discrete reinforcing elements (920,921,922), and these discontinuous reinforcing elements substantially in the circumferential direction along a plurality of concentric circles (C, C1, C2) to the axis of rotation of the tire mounted on the rimsang orientation, and each circle is defined by the mean radius (R, R1, R2) measured relative to the axis of rotation, ; - discontinuous reinforcing element of length L0 located on a circle C of radius R, respectively is immediately adjacent to the circle C, two discontinuous reinforcing elements located on a circle C1 of radius R1 (921) and being mechanically coupled over coupling lengths L11 and L12, L11 is a bond length between 55 and 75% of L0 , coupling length L12 is between 10 and 30% of L0, ; - discontinuous reinforcement elements on the same circle C of radius R placed on each of the two circles of radius C2 R2 immediately adjacent to the original C1 of discontinuous reinforcement elements 922 and is mechanically coupled over coupling lengths L21 and L22, L21 is a bond length between 20 and 40% of L0, L22 is a bond length heavy, characterized in that between 45 and 65% of L0 tires for vehicles carrying lower body parts. ; beads, reinforcing, discontinuous reinforcement elements, tires, parts of the lower body
