  • Publication number: 20140318679
    Abstract: An improved puncture-proof structure for tires is provided. The structure forms a spare tire body that can be assembled rapidly and adapted to various tire types by being finely tuned. A tire using the spare tire body is puncture-proof such that when punctured by sharp articles or knifes, the tire can still work to make safe arrival at a nearby repair workshop. This saves a car driver who has a damaged tire from the trouble of shoving the car and from the danger of endangering his/her life, in turn ensuring the public traffic safety.

  • Patent number: 7918255
    Abstract: A run flat device for use in a wheel assembly comprises a wheel rim made of a plurality of blocks and a tire cover having beads mounted against flanges of the rim. The device includes an annular support structure for mounting around the rim to support the cover, the structure subdivided in at least two ring sectors to form the structure by juxtaposition in the circumferential direction thereof, and means for locking the beads against the flanges to connect the ring sectors to the beads. Each ring sector comprises at least two rigid support elements superposed in the radial direction of the structure and separated in pairs by respective rubber-based resilient layers, the layers adapted to shear based on a lateral force applied to the structure to enable the radially outer support element to be displaced axially relative to the radially inner support element.

  • Patent number: 7913732
    Abstract: A tire insert attachment apparatus includes a pin attached to a first part of the insert and extending into a second part of the insert to engage an actuator that draws the bolt into the second part. The actuator includes a tool engagement head that transmits rotational motion of a tool to a translator via a converter, the converter transforming the rotational motion of the head into linear motion imparted on the translator. The translator can be a rack and pinion setup or can be a thread arrangement. Preferably, the head rotates a worm, which rotates a pinion that has threads formed on an inner surface and engaging mating threads on the pin, the pin taking the form of a bolt, such as an eyebolt.

  • Patent number: 7905264
    Abstract: A pneumatic tire comprises a sidewall reinforcing rubber disposed axially inside the carcass in each of the sidewall portion, and in order improving the ride comfort during normal running without deteriorating runflat performance, the axially inner surface of the sidewall reinforcing rubber is provided with a circumferentially extending groove. When the tire is deflated, the groove in the ground contacting patch is closed and the sidewall reinforcing rubber supports the tire load. When the tire is inflated-normally, as the sidewall portion can be bent around the groove, the ride comfort is improved.

  • Publication number: 20110030869
    Abstract: The present invention relates to a clamp collar of the annular band type provided with connecting means for connecting at least one pair of adjacent ends of the band, and to a run-flat device intended to be fitted to a motor vehicle mounted assembly incorporating same. This clamp collar (40) comprises a band (41), preferably made of metal, having at least one pair of ends (42 and 43) spaced apart in the circumferential direction, connecting means (44) of connecting the or each pair of ends together with adjustable tightening in this direction and a locking member (45) for locking the connecting means. According to the invention, this member is mounted solid with one of these ends (43) being able to occupy an unlocked position in which it is disengaged from these means for tightening and loosening the collar and a locked position in which it engages with them to oppose this loosening.

  • Publication number: 20110017377
    Abstract: A load-bearing structure for a bearing support intended to be mounted on a rim inside a tire fitted on a vehicle to support the tread of the tire in the event of a loss of inflation pressure is provided. The load-bearing structure includes a base, a crown, and an annular body connecting the base and the crown. The body includes a plurality of partitions distributed regularly circumferentially, extending axially substantially from one side to the other of the body and radially from the base to the crown with a mean orientation relative to the radial direction of between 10 and 50 degrees, in that two circumferentially adjacent partitions exhibit contrary orientations relative to the radial direction and in that two adjacent partitions define with the base and/or the crown cavities in the form of triangles or trapezoids.

  • Patent number: 7819156
    Abstract: Disclosed is a tire/wheel assembly which, even in a case of forming a run-flat support member by processing a metal material high in breaking strength, realizes the forming without generating wrinkles and cracks. In the tire/wheel assembly, a run-flat support member is inserted into a cavity portion of a pneumatic tire mounted onto a rim, a run-flat support member being formed of an annular shell having an arched cross-section, and elastic rings attached to bent ends of the annular shell in an inner peripheral side thereof. In the tire/wheel assembly, while plural notches are provided in the bent ends along a circumferential direction thereof, a length Ln (mm) of the notches in the circumferential direction is set between 1.0 mm and 15.0 mm inclusive, and a ratio Ws/Wg of a width Ws (mm) of the bent ends of the annular shell to a thickness Wg (mm) of the elastic rings is set between 0.55 and 0.92 inclusive.
