ABSTRACT:
A tire rim assembly (16) permits inflation of a tire (10) mounted thereon only when the components constituting the structure are assembled in a locking configuration. The tire rim assembly (16) includes a rim base (18) having first and second grooves (32,34) defined on its outer periphery (30), an annular bead seat member (24) arranged around the rim base (18) and having an inner periphery (38) defining a load transferring surface (42), an inner surface (40), and an inclined ramp surface (44) located between the inner surface (40) and the load transferring surface (42), an elastomeric seal (26) is disposed in the second groove (34), and an annular split lock ring (28) is disposed in axially restraining engagement in the first groove (32) and adapted to contact the load transferring surface (42) of the bead seat member (24) with the structure completely assembled. The elastomeric seal (26) is located by a locking surface (52) of the annular split lock ring (28) and elastically deformed by engagement of the inclined ramp surface (44) to establish an air tight seal between the elastomeric seal (26), the second groove (34), and the inclined ramp surface (44) when the lock ring (28) is properly installed. When the lock ring (28) is omitted or improperly installed the elastomeric seal (26) is free of compression and will not establish an air tight seal.
