US 2025/0381802 A1 · NON-PNEUMATIC TIRE

Abstract

The present invention is directed to a non-pneumatic tire comprising a circumferential tread band, spokes arranged radially inwards the tread band, and anchoring rails extending in an axial direction and attached to a radially inner side of the tread band along the circumferential direction. The spokes are slidably mountable to the anchoring rails in the axial direction, connecting the tread band and the spokes by mechanical interlocking. Furthermore, the present invention is directed to a non-pneumatic tire comprising on a radially inner side of a tread band axially extending anchoring portions, and two axially neighboring rows of X-shaped spokes, which are circumferentially shifted relative to each other so that each anchoring portion anchors a radially outer right leg of a spoke in a first row of the axially neighboring rows and a radially outer left leg of a spoke in a second row of neighboring rows of spokes.

Dependent claims

A non-pneumatic tire comprising a circumferential tread band and a plurality of spokes arranged radially inwards the tread band for supporting the tread band,

wherein the tire further comprises a plurality of anchoring rails extending in an axial direction of the tire and attached to a radially inner side of the tread band along a circumferential direction of the tire, and wherein the spokes are slidably mountable to the anchoring rails in the axial direction to mechanically interlock the tread band and the spokes against movement in a radial direction of the tire.

A non-pneumatic tire comprising a radially outer tread band, a plurality of axially extending anchoring portions provided on a radially inner side of the tread band, and a plurality of spokes having an essentially X-shaped cross-section in a plane perpendicular to an axial direction of the tire,

wherein each spoke of the plurality of spokes has a pair of radially inner legs and a pair of radially outer legs, wherein both pairs of legs are connected by a connecting portion of the spoke,
wherein one of the radially outer legs is axially and slidingly mountable to one of the axially extending anchoring portions to mechanically interlock the spoke and the anchoring portion by mechanical form fit against relative radial movement,
wherein the spokes are arranged in at least two axially neighboring circumferential rows of spokes,
wherein the axially neighboring rows of spokes are circumferentially shifted relative to each other so that each anchoring portion mechanically interlocks a radially outer right leg of a spoke in a first row of the two rows of neighboring spokes and a radially outer left leg of a spoke in a second row of the two rows of neighboring spokes, when viewed in the axial direction.
