Abstract:
A runflat tire system comprises a pneumatic tire, a wheel rim on which the pneumatic tire is mounted, and a support ring made of an elastic material and disposed in a cavity surrounded by an inner surface of the rim and an inner surface of the tire mounted thereon, wherein the support ring comprises an annular body extending in a circumferential direction of the tire and being provided with a plurality of recesses each opening at the cavity, and at least two sound reflectors each being attached to the recess and including an outer surface made of a non-porous material so as to reflect sound in the cavity.
Abstract:
A run-flat support ring, which is a component mounted upon a rim inside a tire to extend the distance the tire may travel at reduced or zero inflation pressure, is provided having one or more features that improve the process of mounting the support ring onto a rim and better tolerate variations, within manufacturing tolerances, in the respective diameters of the rim and the support ring.
Abstract:
A safety insert designed to be mounted in an assembly comprising a tire and a rim of a vehicle and device for detecting the bearing of the tire on an insert, so that the insert generates signals oriented parallel to the axis of rotation of the tire and rim assembly and so that the device detects and analyzes the vibrating signals of the chassis of the vehicle.
Abstract:
A run-flat support ring, which is a component mounted upon a rim inside a tire to extend the distance the tire may travel at reduced or zero inflation pressure, is provided having an integrated shelf design that enhances the handling characteristics of the support ring under run-flat conditions and may also lower the overall mass of the support ring in certain applications. In addition, the support ring has one or more features that improve the process of mounting the support ring onto a rim and better tolerate variations, within manufacturing tolerances, in the respective diameters of the rim and the support ring.
Abstract:
A tire/wheel assembly comprising a wheel having a rim, a pneumatic tire mounted on the rim of the wheel and a run-flat support member disposed in the cavity of the pneumatic tire. The run-flat support member includes an annular shell and elastic rings. The annular shell has a support surface located radially outward and two leg portions formed radially inward in a straddling state. The elastic rings support the leg portions on the rim. The annular shell is configured such that an annular cavity portion surrounded by the run-flat support member and the pneumatic tire has a cross-sectional area that varies in the circumferential direction of the tire.
Abstract:
A run-flat support ring, which is a component mounted upon a rim inside a tire to extend the distance the tire may travel at reduced or zero inflation pressure, is provided having an internal fin design that improves the rolling resistance of the support ring without sacrificing the overall load bearing and handling characteristics. Certain embodiments may also include one or more features that improve the process of mounting the support ring onto a rim and better tolerate variations, within manufacturing tolerances, in the respective diameters of the rim and the support ring.
Abstract:
A PNEUMATIC TIRE FORMED OF AN ELASTOMER AND ONE OR MORE FABRIC PLY REINFORCEMENTS, IN WHICH A FABRIC REINFORCEMENT EXTENDS CONTINUOUSLY AROUND THE ANNULAR CROSSSECTION OF THE TIRE AT AN ANGLE OF BETWEEN 70* AND 90* RELATIVE TO THE CROWN THEREOF. THE TIRE IS FASTENED TO AN ELASTIC OR RIGID MEMBER, WHICH MAY BE A WHEEL RIM COMPONENT, BY AN ADHESIVE BOND FORMED BY A SUITABLE ADHESIVE.
