A structurally supported tire includes an outer annular band, and a plurality of web spokes extending transversely across and radially inward from the annular band and anchored in a wheel or hub. The annular band may further comprise a shear layer, at least a first membrane adhered to the radially inward extent of the shear layer, and at least a second membrane adhered to the radially outward extent of the shear layer. A preferred web spoke has a cutaway section transverse to the annular band. The cutaway section has a profile formed by straight line segments joined by a blending radius. The profile of the cutaway comprises a height and a maximum depth greater than five percent of the height and less than thirty percent of the maximum width. The profile has an angle alpha formed by a line tangent to the profile relative to the horizontal at least equal to ten degrees at the radially outermost and radially innermost extent of said profile. The minimum radius of curvature of the profile is at least equal to twenty percent of the height of the cutaway section.

Non-pneumatic tire

A centralized device for dealing with the phenomena of loss of pressure and running flat with a vehicle tire, including a means external to the mounted assembly, permanently fixed to the vehicle and able to inject or otherwise bring into the internal cavity of the tire at least one active product, also external to the mounted assembly, and able to treat the phenomena of loss of pressure and ultimately running flat.

A safety support designed to be inserted by a translation operation around a rim bearing in which the radially inner surface of the base of the support contains a plurality of protuberances radially arranged internally.

A compliant wheel includes a compliant band and a plurality of web spokes extending transversely across and inward from the reinforced compliant band for attachment to a hub. The compliant band bends to comply with a contact surface and to envelope obstacles. The web spokes transmit load forces between the compliant band and the hub through tension in the web spokes not connected to the ground contacting portion of the wheel. The outer surface of the compliant band may be formed to include a tread, or a separate tread band may be attached.

Compliant wheel

A method of lubricating a tire cavity and more particularly the interface zone between a safety support and the inside the cavity of a tire enables lubricant to be dispensed in the interface zone only when the mounted assembly comprising the support, the tire and a wheel is in a runflat condition and where the non-instantaneous contact established between the inside surface of the tread and the seal allows the lubrication port to be unblocked. The invention also concerns a lubrication device and a seal enabling the method to be implemented, and a support and a reservoir enabling implementation of the method.

Wheel rim comprising two rim seats having different diameters, inclined outwards and extended axially outwards by two humps of small height, the rim seat of smaller diameter being connected axially on the inside to a bearing surface via a truncated conical portion and the rim seat of larger diameter being connected axially on the inside to the said bearing surface by a rib of small or zero height, whose axially interior wall has a generatrix that makes with the rotation axis an angle open radially and axially outwards and at the most equal to 30&deg;, characterised in that the said rib, which has an axially inside wall of axial width at most equal to the axial width of the said second seat is provided circumferentially with at least two transverse grooves of small size.

Wheel rim and assembly of such a rim with a bearing support

A tire ( ), a mounting rim ( ) therefor and a circumferentially unstretchable ring ( ) for supporting the tread ( ) of the tire when running at low or zero pressure. The tire ( ) has a radial ply casing ( ) on which the points that are furthest apart axially are radially apart close to seats ( B) of outwardly sloping beads ( ). The seats ( B) engage sloping seats ( ) on the rim ( ), which may have at least one mounting well ( ), at least one cylindrical portion ( ) for receiving the supporting ring ( ) and rim flange ( ).

Radial tire with axially outer bead tip

A rim having a bearing support located between its two rim seats, which bearing support is intended to receive a support ring, is characterized in that this bearing surface comprises at least one surface clamping part, each surface clamping part being regularly distributed in the circumferential direction over the bearing surface and having a maximum external development Ds, measured on an enveloping surface concentric to the bearing surface, which is greater than the development Dp of the bearing surface, in order to create mechanical clamping between a support ring and the surface clamping part which is appropriate to ensure holding of the ring on the bearing surface during travel.

Rim intended to receive a support ring

A tire (1), a mounting rim (2) therefor and a circumferentially unstretchable ring (3) for supporting the tread (10) of the tire when running at low or zero pressure. The tire (1) has a radial ply casing (13) on which the points that are furthest apart axially are radially apart close to seats (12B) of outwardly sloping beads (12). The seats (12B) engage sloping seats (23', 23') on the rim (2), which may have at least one mounting well (22), at least one cylindrical portion (21) for receiving the supporting ring (3) and a rim flange (24).
