The present invention relates to a self-locking mechanism for quick tyre change in rear dual wheel assembly in a heavy transport vehicle. The self-locking mechanism includes a two-piece segmented saddle lock ring 409a, 409b retained in position by an endless ring 406. A self-locking taper 405 provided on inside of the endless ring that can be pressed against on the two-piece segmented saddle lock ring 409a, 409. A lip 702 is provided on the two piece segmented saddle rings 409a and 409b in addition to the self locking taper 413 provided at the interface with endless ring 406. A relief 708 is provided on the inner surface of the endless ring 406.

A multi-piece rim structure for a wheel includes a rim base 10, a bead seat ring 20 (ring member) and a lock ring 30. The bead seat ring 20 receives a load in a radial direction and an axial direction from a bead portion of a tire. An annular ridge 35 of the lock ring 30 can be received in an annular lock ring groove 15 of the rim base 10. A receiving groove 15a is formed in an inner surface of the lock ring groove 15 of the rim base 10. A sacrificial anticorrosion material 80 is embedded in the receiving groove 15a. The sacrificial anticorrosion material 80 includes metal such as zinc and aluminum that has a greater ionization tendency than iron that is a base material of the rim base 10 and the lock ring 30. Corrosion of the rim base 10 and the lock ring 30 can be suppressed by ionization of the sacrificial anticorrosion material 80.

A wheel rim assembly and components, systems, and methods thereof can comprise a rim base having at least one slot at an outer end portion thereof, a bead seat band radially outward of the outer end portion of the rim base, and at least one lock provided in the at least one slot. The bead seat band may be in direct contact with the outer end portion of the rim base. The lock can have a first portion that is provided in the slot of the rim base and a second portion that is outside of the slot. The second portion may be adjacent to the bead seat band. The wheel rim assembly may be free of or without a lock ring at the outer end portion of the rim base.

An aircraft wheel rim includes a main portion and a removable portion. The main portion includes a hub and a disk extending between the hub and an annular outer portion that receives a tire and is shaped to form a rim one of its sides of the annular outer portion. A second side of the annular outer portion is shaped to receive the removable portion, which forms a second flange on the second side of the annular outer portion after a tire has been put into place. The rim further includes a blocking device that limits rotation of the removable portion relative to the main portion. The blocking element include at least one key having a head engaged in a matching receptacle in the removable portion and a root engaging a steel peg that is shrink fitted in the main portion.

A wheel assembly is provided. The wheel assembly includes a rim configured to receive a tire of an off-road vehicle. The wheel assembly also includes a flange member slidably received on the rim. The flange member has a flange portion with a terminal end defining a first axial extent of the flange member. The wheel assembly also includes a locking ring radially and axially interposed between the rim and flange member. The wheel assembly also includes a locking arrangement mounted between the rim and the flange member which has a second axial extent. The second axial extent is substantially axially adjacent to the first axial extent.

The present invention relates to a novel design for quick tyre change in rear dual wheel assembly in a heavy transport vehicle. The invention provides a safe design that comprises a two-piece segmented saddle lock ring retained in position by an endless ring. A self-locking taper provided on the inside of endless ring can be pressed against the taper provided on the two-piece segmented saddle lock ring. The endless ring retaining the two-piece segmented saddle lock rings due to wedge action of self-locking taper cannot move from its position until an external force is applied on the endless ring towards the direction of the tyre position. The endless ring acts as a hood over the two-piece segmented saddle lock rings and prevents any loose parts flying off the rim during the tyre burst. Further in this safe design both inboard and outboard rim tyre support components are identical as both rims are of same diameter.

A wheel rim assembly and components, systems, and methods thereof can have a rim base with at least one slot at an outer end portion thereof, a bead seat band radially outward of the outer end portion of the rim base, and at least one lock provided in the at least one slot. The bead seat band may be in direct contact with the outer end portion of the rim base. The lock can have a first portion that is provided in the slot of the rim base and a second portion that is outside of the slot. The second portion may be adjacent to the bead seat band. The wheel rim assembly may be free of or without a lock ring at the outer end portion of the rim base.
