摘要:
The invention provides a method for balancing tire performance with both increased and decreased numbers of lugs on the ribs while also having desirable tire noise performance. This method allows the tire designer to take advantage of the benefits of both high and low pitch count patterns while minimizing undesirable tire noise. The method involves the design of the fundamental pitch of the tire tread pattern and the design of the tread pattern for the tire. The invention also provides tires incorporating the fundamental pitch and tread patterns.

A method for encapsulating a monitoring device for a pneumatic tire, wherein the monitoring device includes a threaded rod and a pressure sensor, includes the steps of positioning the monitoring device in an encapsulation chamber of an encapsulation device with a portion of the threaded rod extending from the encapsulation chamber, engaging the threaded rod against the encapsulation device to suspend the electronic monitoring device within the encapsulation chamber; and filling the encapsulation chamber with encapsulation material to encapsulate the monitoring device to form an encapsulated monitoring device. The encapsulated monitoring device may be mounted to a pneumatic tire with an attachment patch.

A tire, which has a maximum section width, an upper section above the maximum section width, and a lower section below the maximum section width, includes a circumferential tread, a pair of sidewalls, and a pair of bead portions. The tire further includes at least one carcass ply extending circumferentially about the tire from one bead portion to the other and first and second reinforcement plies extending circumferentially about the tire. The first and second reinforcement plies are provided between the at least one carcass ply and at least one of the sidewalls of the tire. The first and second reinforcement plies include lower ends that terminate in the lower section of the tire and upper ends that terminate in the upper section of the tire.
摘要:
A method of developing a set of input forces used to analyze tire wear includes the steps of characterizing a wear course by driving a vehicle over the wear course and measuring data related to a plurality of forces experienced by the vehicle. A vehicle characterization model for a target vehicle having at least one tire is developed. The vehicle characterization model is used to calculate force data that represents the forces that would be experienced by at least one tire of the characterized vehicle if the characterized vehicle were driven over the characterized wear test course in the first vehicle configuration. The force data is then used to analyze tire wear using a computer prediction technique or by running an indoor wear test on the tire.
摘要:
A tire and a method of securing an object thereto includes a two-piece fastening system (22) having a first portion (20) which is applied to an innerliner (12) of a green tire prior to the green tire being cured and a second portion (30) which includes an object, such as a radio frequency identification chip (32), attached thereto. The first portion (20) of the two-piece fastening system is attached to the innerliner (12) of the tire with an adhesive or by curing. The green tire is then cured and the second portion (30) of the two-piece fastening system (22) with the object (32) attached thereto is then attached to the first portion (20) of the two-piece fastening system. In an alternative embodiment, the object (32) may be sandwiched between the first (20) and second portions (30) of the fastening system.
摘要:
A monitoring device (100, 102) for a pneumatic tire (106) includes a body (114) having a central portion (116) with a monitoring assembly (112) carried by the central portion. A plurality of spaced fingers (118) project from the central portion (116) of the body. The fingers (118) support the monitoring assembly (112) in a spaced located from the inner surface (120) of the tire (106). The fingers (118) also cushion the monitoring assembly (112) and raise it above any liquid (128) that may be disposed in the tire. In one embodiment (102), the fingers are designed to position the center of the device (110) at the center of the tire sidewall (126). In this embodiment, the fingers may be configured to engage the tire (106) and rim (104) at the same time.
摘要:
A non-attached monitoring device includes monitoring assembly and an antenna configured to radiate signals from the monitoring assembly. The antenna is configured to radiate through the oriented attenuating body of the tire sidewall regardless of the position of the monitoring device with respect to the tire sidewall. In one embodiment, the antenna has a body that is looped back on itself. The body may be parallel to or perpendicular to the antenna ground plane. In another embodiment, a radiating slot antenna is configured to provide transmissions through the tire sidewall regardless of the position of the monitoring device.
