Abstract
A run-flat tire of improved load bearing capacity after being punctured is disclosed. The tire has two circumferential sidewalls, at least one circumferential intermediate wall interposed between the sidewalls, and a transverse base extending from one sidewall to the other and defining a compartment between a sidewall and an adjacent intermediate wall or between two adjacent intermediate walls. Each compartment is adapted to assume an expanded symmetrical configuration when an adjacent sidewall or intermediate wall is punctured. A carcass portion is provided within each sidewall, each intermediate wall and base. A shock absorber is provided in the vicinity of a junction connecting each intermediate wall to the base. A padding element is affixed to the inner liner portion applied to the bead wrap of each intermediate wall.
Claims17
A run-flat tire comprising:
- a. two circumferential sidewalls terminating with a bead wrap at a portion thereof which is proximate to a tire rim;
- b. at least one circumferential intermediate wall interposed between the sidewalls and terminating with a bead wrap at a portion thereof which is proximate to said rim;
- c. a transverse base extending from one sidewall to the other, thereby defining a compartment between a sidewall and an adjacent intermediate wall or between two adjacent intermediate walls;
- d. a carcass comprising a portion which is embedded within each sidewall, each intermediate wall and base, a carcass portion within an intermediate wall being connected to a carcass portion within said base by a T-shaped connection;
- and
- e. shock absorber means provided in the vicinity of said T-shaped connection, said shock absorber means comprising a sponge,
- wherein each of said compartments is adapted to assume an expanded symmetrical configuration when an adjacent sidewall or intermediate wall is punctured.
A run-flat tire comprising:
- a. two circumferential sidewalls terminating with a bead wrap at the inner portion thereof;
- b. at least one circumferential intermediate wall interposed between the sidewalls and terminating with a bead wrap at the inner portion thereof;
- c. a transverse base extending from one sidewall to the other, thereby defining a compartment between a sidewall and an adjacent intermediate wall or between two adjacent intermediate walls;
- d. a carcass comprising a portion which is embedded within each sidewall, each intermediate wall and base;
- and
- e. shock absorber means provided in the vicinity of a junction connecting each of said intermediate walls to said base,
- wherein the shock absorber means is a ball joint, said ball joint being received in a socket which is connected to the carcass portion within an intermediate wall and the carcass portion within said base,
- wherein each of said compartments is adapted to assume an expanded symmetrical configuration when an adjacent sidewall or intermediate wall is punctured.
