Cap ply reinforcement strip in pneumatic tire
The cap ply reinforcement strip is a ready-to-use plain woven fabric and is composed of hybrid cord warps (3) and texturized weft yarns (2). The cap ply reinforcement strip for pneumatic tires (1) eliminates calendering and strip preparation steps by eliminating the need for rubber coating and decreases the rolling resistance of the tire and the fuel consumption.
Track system for traction of a vehicle
A track system for traction of a vehicle (e.g., an all-terrain vehicle (ATV), an agricultural vehicle, etc.) may be designed (e.g., may comprise non-pneumatic tires) to enhance its use or performance and/or that of the vehicle such as, for example, by being lightweight and/or by better handling loads, including, for instance, those resulting from track tension within the track system and/or from unevenness or other aspects of the ground, including encounters (e.g., impacts) with obstacles on the ground (e.g., rocks, portions of trees, debris, bumps, abrupt changes in ground level, etc.). The track system may comprise tension-based non-pneumatic tires.
Tire with asymmetric crown
Tire formed of two halves separated by a median plane, comprising a crown comprising a crown reinforcement comprising a first reinforcing ply (80) and a second reinforcing ply (90) having two axial ends, which is situated radially on the outside of the first reinforcing ply and surmounted by a hooping reinforcement (100) made up of circumferentially orientated reinforcing elements, in which tire the absolute value of the difference D between the distance D1 of the first axial end (92) from the median plane and the distance D2 of the second axial end (93) from the median plane is greater than or equal to 4 mm and less than or equal to 10 mm (4 mm|D|=|D1D2|10 mm).
NON-PNEUMATIC TIRE WITH MULTI ANGLE TENSION CONTROL REINFORCEMENTS
A non-pneumatic tire is provided. The non-pneumatic tire includes an outer annular portion, an inner annular portion, and a load bearing ring positioned between the outer annular portion and the inner annular portion. The load bearing ring includes at least one reinforcing layer, and each of the at least one reinforcing layers includes one or more strips of multi angle tension control reinforcement (MATCR) material.
ASSEMBLY FOR TIRE INCLUDING IMPREGNATED WOVEN OR KNITTED FABRIC(S) AND A SACRIFICIAL HOLDING MEANS
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.
Shear band construction
A shear band for a tire includes an annular first, radially outer fabric layer extending circumferentially around the tire; and an annular second, radially inner fabric layer extending circumferentially around the tire. The shear band is formed from a single shear band strip helically wound circumferentially and axially with a first edge of the shear band strip. The first edge of the shear band strip has a first extension flap for engaging an opposite second edge of the shear band strip. The first extension flap is continuously secured to the opposite second edge linearly along the opposite second edge of the shear band strip.
KNIT BODY AND TIRE
A knit body according to the disclosure is knitted out of a filament body including at least one metal fiber having a cross section orthogonal to a longitudinal direction, the cross section having a profile that is convex polygonal.
Pneumatic Tire, Having Working Layers Comprising Monofilaments And A Tire Tread With Incisions
Technique to increase the endurance of tires comprising two crossed working layers (41, 42), comprising mutually parallel reinforcing elements that form, with the circumferential direction (XX) of the tire, an angle which is at least equal to 20 and at most equal to 50. The reinforcing elements are made up of individual metal threads or monofilaments having a cross section which is at least equal to 0.20 mm and at most equal to 0.5 mm. The tire also comprises axially exterior sipes (24) having a mean width W at most equal to 1 mm, of a depth D at least equal to 5 mm and spaced apart, in the circumferential direction (XX), by a circumferential spacing P at least equal to 4 mm, and axially exterior grooves (25) having a mean width W at least equal to 1 mm, of a depth D at most equal to 5 mm.
TIRE PLY STEEL FABRIC HAVING SPECIFIED WEFT CORDS, RUBBER COVERED TIRE PLY THEREOF, AND RELATED PROCESSES
Disclosed herein are a tire ply steel fabric having specified weft cords, a rubber covered tire ply comprising the tire ply steel fabric, tires comprising the rubber covered tire ply, and related processes for producing a tire ply steel fabric with specific weft cords and for producing a rubber covered tire ply comprising the tire ply steel fabric. The tire ply steel fabric comprises a plurality of steel warp cords and a plurality of weft cords each weft cord having a core-sheath construction wherein the core comprises at least one filament of a non-metallic material having a specified Eb and the sheath comprises a different non-metallic material having a specified Eb that is lower than the Eb of the core material.
TIRE FOR ATTENUATING ROLLING NOISE
Present disclosure provides a tire including a summit surrounded on both sides by sidewalls, including a carcass reinforcement extending in the summit and the sidewalls, and anchored at its two ends in the beads, the carcass reinforcement being surmounted radially on the outside by a summit reinforcement composed of a plurality of reinforcing plies, said summit reinforcement being surmounted radially on the outside by a tread intended to come into contact with a ground during use of the tire, the tire comprising in its summit, at least one cavity acting as a resonator and in fluid communication with the outside of the tire, when the tire is mounted onto a mounting rim each cavity having an appropriate volume to form a calibrated resonator to attenuate the noise in a frequency range between 500 and 2000 Hz.
