TYRE WITH MONITORING DEVICE
The present invention relates to a tyre (11) having an inner surface (111) and provided with at least one monitoring device (3) adhering to said inner surface (111), wherein said monitoring device (3) is made on a flexible support, and wherein the adhesion of said flexible support to said inner surface (111) is achieved through a decoupling element (4) interposed between said at least one monitoring device (3) and said inner surface (111) of the tyre (11).
METHOD FOR GENERATING LOAD ESTIMATION MODEL IN TIRE UNIFORMITY TESTER
In a tire uniformity testing apparatus which measures uniformity of a tire by measuring a load applied to the tire pressed against a rotary drum, a load estimation model is generated which is used to control a pressing position of the rotary drum, and generates a load estimation model indicating a relation between the pressing position of the tire with respect to the rotary drum and the load applied to the tire. The load estimation model is generated by: holding the tire in which uniformity has already been measured for each characteristic value; acquiring a nominal model depending on the characteristic value of the tire; and generating based on the acquired nominal model.
PNEUMATIC TIRE
Provided is a pneumatic tire having sufficient sealing performance. The present invention relates to a pneumatic tire including a sealant layer located radially inside an innerliner, the sealant layer being formed by applying a sealant to the inner periphery of a tire from which mold release agents have been removed.
Multiple Layer Foam Insert for Tires
A multiple layer foam insert replacement for a pneumatic inner tube for a tire. The multiple layer foam insert emulates the effect of air pressure, across a range of pressures, while still approaching the weight of the air filled tube. Through the use of different density materials and the orientation and thickness of such materials, the desirable characteristics of the pneumatic tube structure and performance can be emulated to a high degree. This multiple layer foam insert can be produced in varying levels of quality and function through the method of extrusion of foam materials in different sizes and layering.
Dipping bath compositions for treating reinforcing inserts
The present invention relates to an aqueous, solids-containing dipping bath composition for treating reinforcing inserts for rubber products comprising the following components or consisting of these components, (A) at least one blocked MDI mixture, the MDI mixture comprising MDI oligomers of formula (I), n being a whole number from 1 to 8, and MDI monomers; (B) at least one latex; (C) at least one compound selected from the group consisting of polyacrylates, lignin derivatives and mixtures hereof; and (D) possibly at least one additive; the dipping bath composition being essentially free of epoxides, and the dipping bath composition being essentially free of resorcinol, formaldehyde and the reaction products thereof. ##STR00001##
Tire for a handling vehicle
A tire for a handling vehicle, designed to transport heavy loads, over short distances and at low speeds, and a mounted assembly consisting of a tire mounted on a rim. Also, a method for producing such a mounted assembly. A mounted assembly includes a tire mounted on a rim, having a tread designed to come into contact with a ground, two sidewalls extending radially inwards from the ends of the tread, and two beads extending the sidewalls radially inwards and in contact with the rim, an internal cavity containing a filling component consisting of at least one incompressible solid element, and which is a granular filling component consisting of granules at least partly separated from one another by interstices containing at least gas, and the fill rate, which is the ratio between the total volume of the granules, the total of the elementary volumes of the granules, and the volume of the internal cavity, is at least equal to 0.8.
Tread cracking inspection device
The present invention comprises methods and apparatus for inspecting a tread. Such methods include providing a tread having a top side and a bottom side, one of the top and bottom sides including a tread feature extending into the thickness of the tread. Such methods further include bending mechanically a transverse extent of the tread relative the tread thickness along a portion of the tread to be inspected about a bending member to form a bent portion of the tread, the portion of the tread to be inspected including the tread feature such that the step of bending expands the tread feature to further expose a depth of the tread feature within the thickness of the tread for inspection. Such further methods include constraining the tread on opposing sides of the portion of the tread to be inspected to maintain the bent portion of the tread in a bent arrangement.
METHOD FOR ESTIMATING LOAD MODEL IN TIRE UNIFORMITY TESTER
A tire uniformity testing apparatus (1) measures uniformity of a tire (T) by measuring a load generated on the tire (T) pressed against a rotating rotary drum (2). A load model used to control a pressing position of the rotary drum (2) and express a relation between the pressing position of the tire (T) against the rotary drum (2) and a tire load generated in the tire (T) is configured to successively measure the tire load, while changing the pressing position of the tire (T) against the rotary drum (2), and to estimate the tire load using the measured value of the measured tire load.
SOLID TIRE PERFORMANCE SENSING SYSTEM AND METHOD
In accordance with presently disclosed embodiments, a tire monitoring system is provided. The tire monitoring system utilizes a heat sensor embedded in a solid rubber tire. The heat sensor detects a temperature of the solid tire, and a transmission system transmits signals indicative of the temperature from the heat sensor to a remote monitoring system. The remote monitoring system may monitor the temperature of the solid tire and output notifications to alert a user when preventive maintenance is needed. The heat sensor may be embedded in the solid rubber tire during the manufacture of the solid tire, or the heat sensor may be embedded into the solid tire after production of the tire is complete. The system may be used track cure time and temperature as the tire is being produced and/or to log tire performance information throughout the operation of the tire.
Tire Uniformity Improvement Through Identification of a Composite Uniformity Parameter Using Multivariate Normal Distributions
Methods and systems for improving the uniformity of a tire are provided. More specifically, one or more characteristics of a composite uniformity parameter can be determined from uniformity summary data (e.g. uniformity vectors) associated with a plurality of harmonics of the composite uniformity parameter. For instance, a peak to peak range of a composite uniformity parameter and/or a distribution of amplitudes of a composite uniformity parameter for a set of tires can be determined from uniformity vectors associated with selected harmonics of the composite uniformity parameter. According to example aspects of the present disclosure, the one or more characteristics of the composite uniformity parameter can be determined using multivariate normal distributions (e.g. bivariate normal distributions) of the uniformity summary data. Once identified, the one or more characteristics can be used to modify tire manufacture to improve tire uniformity.
