摘要:
A tool for seating a tubeless tire on a rim using pressurized gas includes a cylindrical pressure vessel with a pistol grip extending radially from the tank. The tool includes a rapid opening gas valve positioned between the cylindrical pressure vessel and a nozzle. In some embodiments the nozzle includes a jet configured to receive pressurized gas from the cylindrical pressure vessel into a chamber of the nozzle so that as the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. The tire is seated on the rim by positioning the system so that the air from the nozzle rapidly blows into the tire between the bead of the tire and the rim upon the valve being opened.

A wheel assembly includes a wheel base, 12, and a side rim, 14, disposed about the wheel base, 12. A recess, 38, is formed on an inside surface, 36, of the side rim, 14. A cavity, 20, is disposed between the wheel base, 12, and the side rim, 14. An air seal, 18, is disposed between the wheel base, 12, and the side rim, 14. A locking mechanism secures the side rim, 14, in position around the wheel base, 12. The locking mechanism is configured to prevent the air seal, 18, from disengaging with the inside surface, 36, and allowing air to exit the wheel assembly between the wheel base, 12, and the side rim, 14, with the locking mechanism is properly installed. The locking mechanism is also configured to permit the air seal, 18, to disengage the inside surface, 36, and allow air to exit the wheel assembly between the wheel base, 12, and the side rim, 14, with the locking mechanism is not properly installed.

An apparatus (300) for processing a tire (T) and a wheel (W) for forming a tire wheel assembly (TW) is disclosed. The apparatus (300) includes a tire support member (316) including a first tire support member (316a), a second tire support member (316b) and a third tire support member (316c). Each of the first, second and third tire support members (316a, 316b, 316c) include an upper surface (316') and a lower surface (316"). The apparatus (300) includes a plurality of tire engaging devices (320) including a first tire tread engaging post (322b') and a second tire tread engaging post (322c'). A method for processing a tire (T) and a wheel (W) for forming a tire wheel assembly (TW) is also disclosed.

A single-cell workstation for processing a tire-wheel assembly including a tire and a wheel is disclosed. The single-cell workstation includes a mounting and indexing sub-station including a first plurality of tire engaging portions including one or more first tire-engaging surfaces, and a second plurality of tire engaging portions including one or more second tire-engaging surfaces.
摘要:
A method and a device for fixing a run flat support body to a pneumatic tire capable of avoiding the deterioration in the weight balance of wheels by preventing a lubricant applied to the inner surface of the tire from being nonuniformly distributed when the run flat support body is used. In the fixing method, the run flat support body formed of a pair of elastic rings disposed around a rim and an annular shell installed across these elastic rings is fixed to the pneumatic tire to which the rim is fitted while the run flat support body is inserted into the hollow part of the tire. The fixing device for restricting the radial movement of the run flat support body inserted into the hollow part is fitted to at least one of the bead parts of the pneumatic tire before the rim is fitted thereto to coaxially hold the pneumatic tire and the run flat support body (3) by the fixing device.
