Complete wheel for vehicle

摘要

The combined tyre and wheel system has a rim(2) with a rounded lip(6) on both sides and each rim lip has a tubular hollow chamber(12) with a rectangular or square cross-section and an annular opening(8) into which the bead area of a special tyre is inserted. Remaining space(16) in the tubular hollow chamber(12) is filled with a liquid fluid material. In a design variation the tyre has a hollow bead area into which, after location of the tyre bead in the tubular chamber of the rim, a curable liquid material is injected to expand the bead until it fills the chamber. Assembly of the tyre and rim involves rotating the tyre bead(14) in the longitudinal direction and inserting through the annular opening(8) into the hollow chamber(12) where, due to the elasticity, it recovers to its original position. Any remaining space(16) in the hollow chamber(12) is then filled with a curable liquid material either via a hole(20) or through the annular joint(8). The bead(14) position is then adjusted to optimise roundness before the liquid sets. A bead area with an internal hollow chamber can be expanded with a curable fluid until the bead completely fills the tubular chamber(12).
