Method for fabrication of a non-pneumatic survivable tire and wheel assembly

摘要

A non-pneumatic tire and wheel assembly is fabricated by forming inner and outer mold elements having apertures to receive casting blocks. A tread having an inner wall is prepared for casting and fill apertures are machined in a rim of a metal wheel. The tread, the outer mold element, the wheel, the inner mold element and the rubber casting blocks are assembled and an elastomer is introduced into the mold assembly through fill tubes inserted in the fill apertures of the wheel. The elastomer is allowed to cure at room temperature to form a tire body element and the rubber casting blocks and inner and outer mold elements are disassembled. A post-cure of the disassembled tire body element is accomplished at a high temperature.
