摘要： A method of making a tire tread includes providing a sheet of material and forming the sheet of material into a cylinder, such that a first edge of the sheet of material contacts a second edge of the sheet of material. The method also includes welding the first edge to the second edge to form a welded joint of a seamed cylinder, and providing tread rubber about the seamed cylinder.

摘要： A non-pneumatic tire includes an annular inner ring, an annular outer ring, and a support structure positioned between the annular inner ring to the annular outer ring. The support structure includes a multilayer structure of a rubber skim layer and a cord embedded in the rubber skim layer. The rubber skim layer has resistance to ozone exposure without need for a protective layer overlying the rubber skim layer. The rubber skim layer exhibits adhesion to embedded metallic cords. Methods of making a non-pneumatic tire include forming a multilayer structure by applying a skim layer directly over one or more cords.

摘要： The present invention relates to a multi-core semi-pneumatic tire and to methods for manufacturing the same. The semi-pneumatic tire includes an outer surface (101) configured to contact ground; an inner surface (103) configured to contact a wheel; and a plurality of hollow cores (107a, 107b) formed between the inner and outer surfaces in the semi-pneumatic tire, wherein each hollow core extends around a circumference of the tire. In one embodiment, the method comprises extrusion of a rubber-like material through a mold; aligning the distal ends of the extruded rubber-like material to form a circular shape for the extruded rubber-like material; and vulcanizing the distal ends to form a tire.

摘要： A mold 810) for manufacturing a spoke for a non-pneumatic tire is provided that has first and second mold pieces (16, 22) with first and second engagement surfaces to engage the spoke. The first mold piece (16) has a void (20), and is movable relative to the second mold piece. A volume compensation feature (26) is carried by the first mold piece (16) and has a base that is located at the void. The volume compensation feature has a deflection plate (30) that engages the base, and has a non-deflected orientation and a deflected orientation. When the mold is closed the spoke engages the deflection plate and deflects the deflection plate relative to the first engagement surface so as to be in the deflected orientation.

摘要： This disclosure includes methods and apparatus for forming a non-pneumatic tire carcass comprising an inner hub, an outer band, and a plurality of spokes. The method includes arranging the inner hub, the plurality of spokes, and the outer band to form a curing assembly arranged in a first arrangement within a forming apparatus, where the inner hub is arranged concentrically within a radially inner annular side of the outer band and the plurality of spokes are arranged between the outer band and the inner hub. The plurality of spokes are forced in opposite radial directions from the first arrangement and to a second arrangement, where each spoke of the plurality of spokes is forced in a curing position against the inner hub and towards the outer band in a curing arrangement. The plurality of spokes are then cured to each of the inner hub and outer band.
