摘要:
Disclosed are an improved wheel and tire for simulating the appearance of a larger-diameter wheel mounted within a low-profile tire. The wheel has an inboard side and an outboard side with a wide outer flange extending around the outer circumference of the wheel. The outer flange is preferably integral with the outboard face of the wheel. A design, preferably comprised of a plurality of protrusions, indentations, and slits, extends across at least a portion of the outboard face of the wheel, including the outboard face of the extended outer flange. In the improved tire, the outboard tire wall preferably includes a laterally extending wheel protector, a ledge, and a flange seat. The flange seat is preferably contoured to match the inner face of the outer flange of the improved wheel.

An attachment between a monitoring device and an innerliner of a tire includes the use of an epoxy adhesive that bonds the monitoring device directly to the inner surface of the innerliner of the tire. The innerliner is first roughened in a manner that provides a roughened portion of the innerliner without removing the entire thickness of the innerliner. The entire thickness of the innerliner is not removed because the innerliner is preferably more than {fraction (1/16)} of an inch thick. The thickness of the innerliner allows the rigid cured epoxy to bond the monitoring device to the inner surface of the innerliner while allowing the innerliner to flex with the tire so as to not break the seal between the rigid epoxy and the innerliner. The monitoring device is preferably located at a low flex area of the tire to help avoid the problem of the innerliner flexing.

The traversing machinery (7) allows to move the trolley (2) along a girder (11), for example. Rope pulleys (5) are used to reduce the strength of the rope. A part of the traversing machinery (7) is arranged inside at least one rope pulley (5) in such a manner that at least one shaft in the traversing machinery (7) remains at least partly inside the rope pulley (5).

A method of improving high-speed radial force variation of a pneumatic tire is disclosed. The tread portion is provided on the radially inner surface with an elastic patch. The weight and position of the patch determined based on (A) a low-speed fundamental RFV or (B) a low-speed fundamental RRO or (C) a weight imbalance of the tire. In case (A), the position is a point of the minimum low-speed fundamental RFV and the weight is {(F×TR)/332}×1000×a1. In case (B), the position is a point of the minimum low-speed fundamental RRO and the weight is {(RO×TR)/332}×1000×a2. In case (C), the position is a light weight position and the weight UB×(RR/TR)×a3. Here, TR is the radius in meter of the tire, F is the maximum variation of the low-speed fundamental RFV, RO is the maximum variation of the low-speed fundamental RRO, RR is the radius of the wheel rim, UB is the tire imbalance, a1 is coefficient in a range of from 0.5 to 3.0, a2 is a coefficient in a range of from 100 to 400, a3 is a coefficient in a range of from 0.5 to 2.0.

摘要:
The present invention relates to a tire comprising a means for indicating the position of a tire among the set of tires of a vehicle. The means is a button, which is fitted in a recess made in the center of a pattern which illustrates the tire positions of the vehicle, so that the position of this particular tire among the set of tires of the vehicle can be indicated unambiguously by turning the button by means of the pattern on the button. The button has a groove and/or an embossment for turning the button by means of a screwdriver with a chisel head, a coin or a pair of pliers, for instance.
摘要:
A wheel-and-tire apparatus has a pneumatic tire with two or more circumferential tread sections, the relative diameters of which may be adjusted to select the tread sections in contact with the road. The tire may have one or more air chambers. The apparatus facilitates selective use of tire tread designs and compositions having different performance characteristics to suit particular road conditions and vehicle operating parameters. Adjustment of tread section diameters is accomplished using tread diameter adjustment means having a source of compressed air. Sensors monitor selected operational parameters of the vehicle and transmit corresponding signals to a computer, which selects an optimal configuration of tread section diameters to suit the data from the sensors. The computer sends a corresponding signal instructing the tread diameter adjustment means to adjust the diameter of one or more tread sections as required to achieve the selected configuration of tread section diameters.

Method and apparatus for mounting a transponder module (602, 602a, 702, 951, 1000, 1020, 1102, 1102′, 1402) and an antenna (740, 740′, 862, 940, 1140, 1140′, 1200, 1300, 1320, 1360, 1360′, 1440, 1460) in a pneumatic tire (312, 630, 1204, 1350, 1350′), and for coupling or connecting the antenna to the transponder module. A patch (600, 700, 700′, 850, 950, 980, 1100, 1100′, 1210, 1356, 1356′, 1400) has an opening (620, 720, 720′, 856, 956, 986, 1120, 1120′, 1420) extending to a cavity (622, 722, 860, 960, 990, 1122, 1122′, 1422) within the body of the patch. The transponder module is removably retained in the cavity by a resilient annular lip (624, 724, 724′, 858, 958, 988, 1124, 1124′, 1424) extending around the opening. End portions (742/744,742′/744′, 864/868, 942/944, 972/974, 1142/1144, 1142′/1144′, 1322e/1324e, 1362/1364, 1362′/1364′) of the antenna extend into the patch, and may be connected to a coupling coil (750, 750′, 866, 938, 968) disposed within the patch for coupling RF signals from the antenna to a corresponding coupling coil (760, 760′, 953, 1004, 1024) in the transponder module. Alternatively, the patch may have contact pads or plugs (1152/1154, 1152′/1154′, 1452/1454) disposed therein for making electrical connections with corresponding contact pads (1132/1134, 1132′/1134′, 1432/1434) disposed on an external surface (1106, 1406) of the transponder module.
摘要:
A pneumatic tire and monitoring device for monitoring an engineering condition of a pneumatic tire includes a pneumatic tire having a sidewall and a plurality of reinforcing cords carried in the sidewall. The monitoring device includes a sensing element that senses at least an engineering condition of a pneumatic tire and transmits the gathered data from the monitoring device to a data gathering device outside of the tire. The transmission occurs through a dipole antenna that is in communication with the sensing element. The dipole antenna is disposed substantially perpendicular to the reinforcing cords in order to maximize the probability of signal propagation through the tire sidewall.
