Abstract: The present invention relates to new polyurethane or polyurea organic reinforcing fillers for elastomeric tyre compounds, tyre components and tyres for vehicle wheels that comprise them. Advantageously these organic fillers allow reducing the weight of the elastomeric compounds that include them and confer to the materials a hysteresis that is in line or even lower, moduli stable at different temperatures, and high load/elongation at break.

Abstract: In a process for building tyres for vehicle wheels, at least one tread band (9) or other elastomeric component of a tyre (2) is made by applying at least one continuous elongated element (14) according to a plurality of turns (C) around a forming drum (15) rotating around a geometric rotation axis (X) thereof. The continuous elongated element (14) is made by the action of extruding a first material through an extrusion nozzle (16), to form an inner core (33) of said continuous elongated element (14) exiting from an outlet opening (18) of the extrusion nozzle (16). During the extrusion, a second material different from the first material is conveyed around the first material, at the extrusion nozzle (16) and upstream of the outlet opening (18), to form a coating layer (32) which entirely surrounds the inner core (33).

Abstract: A tyre includes at least one block on which at least one complex type sipe is obtained separating the block into two portions having a first surface and a second surface facing each other. The first surface is extended between a set of first and second longitudinal sections having, respectively, a first and a second radial profile, which are symmetrical to each other, each one comprising a coupling portion between the two block portions formed by a protrusion and a recess defined by three consecutive inclined lengths, the pattern of which is such that the ends of the coupling portion are offset from each other along a direction transverse to the longitudinal direction of the sipe.

Abstract: A working station for deposition of elementary semifinished products for building green tyres includes at least one feeding apparatus for feeding an elementary semifinished product, a forming drum, an anthropomorphic robotized arm associated with the forming drum, a control apparatus for sending movement commands to the anthropomorphic robotized arm in order to move the forming drum in a working zone, and a calibration device for calibrating the anthropomorphic robotized arm. The calibration device includes a base plate, a support rotatably mounted on the base plate, and a reference element translatably mounted on the support. The support is positionable in a plurality of first positions relative to the base plate and the reference element is positionable in a plurality of second positions relative to the support and is fixed into one position of the plurality of second positions by inserting at least one pin or screw into one slot of a plurality of slots on the cursor. The control apparatus is also configured for determining target coordinates, retrieving from a memory area a correction function, modifying the target coordinates by means of the correction function, and using processed coordinates for sending the movement commands.

Abstract: A tyre with a tread band having a plurality of blocks. The blocks include three-dimensional sipes extending in a direction incident to an advance direction of the tyre. Each sipe separates a block into a first block portion having a first surface facing the advance direction, and into a second block portion having a second surface facing the direction counter to the advance direction. Male/female couplings are provided between the first and the second block portions, the couplings formed by protuberances on the first surface and extending towards the second block portion, and by recesses on the second surface and extending away from the first block portion. The protuberances formed on the first surface have an apex that is spaced apart from the tread surface by no more than 40% of the depth of the three-dimensional sipe, measured at the apex.

Abstract: Tyre (1) particularly suitable for applications for commercial vehicles, comprising a tread band (2) which has a plurality of blocks (7, 8) facing each other in pairs and delimited in a circumferential and/or axial direction by a first plurality of main grooves (10, 20) which extend continuously up to the opposite shoulder regions (4, 5) starting from the central region (6), where they are connected to each other and by a second plurality of main grooves (30, 40), also extending from the central region (6) towards the shoulder regions (4, 5), connected to the first main grooves (10, 20) by means of a portion (30b, 40b) preferably tapered in width until it becomes a thin connecting sipe (30c, 40c).

Abstract: A method and system for estimating an unevenness parameter of a road segment having a length (L) are disclosed; the method and system take into account road unevenness induced vehicle body motions and are based on the estimation of the deformation, over multiple tire rotations, of at least two tires fitted to different axles of a vehicle.
