摘要:
A tyre changing apparatus for removing a tyre (3) from a corresponding rim (4) of a wheel (2), a bead breaker tool movable towards and away from the supporting element (6) along a movement direction (B) with an actuator and control means (14) connected to the actuator. The control means (14) comprise a processor (18) which is set up to receive data representing a curve of the feed speed of the bead breaker tool (9) towards the supporting element (6) and which is programmed to identify a position of contact of the tool (9) with the tyre (3) as a function of a deceleration of the bead breaker tool (9).

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.

A non-pneumatic tire and wheel assembly incorporates a tire tread (22) and a conventional vehicle wheel (26) with an elastomer tire body (10) element molded for engagement intermediate the tread and wheel. The tire body element includes multiple concentric layers (12,14) with alternating spokes (16). A bonded multilayer cover (52) may be employed which is received within a recess in an outer surface of the tire body element from the tire tread. A mounting plate (50) is engaged to the cover and attached to the wheel.

A method is provided for refitting a tire system on a compact tractor (10) which typically comes equipped with a set of industrial tires mounted on standard industrial size wheels. A set of replacement agricultural tires or turf tires is provided. The replacement tires are sized to fit on the standard industrial size wheels while having rolling circumferences substantially equal to rolling circumferences of standard agricultural tires or turf tires, respectively, for the compact tractor in question. The industrial tires are replaced with the replacement agricultural tires or turf tires without changing at least the front wheels (18) on the compact tractor (10).

The invention relates to a vehicle wheel with an especially single-piece rim and a tubeless tire which is suitable for emergency use. Said wheel comprises an emergency support surface embodied on the radially outer rim surface; a bead whose peripheral length can be especially elastically modified and which is embodied on each side wall of the tire, thickens towards the internal side of the tire and serves to fix the tire to the rim; at least one annular chamber embodied as a single piece in at least one axial face of the rim, comprising a radially internal wall, a radially external wall, an axially internal wall in relation to the rim centre and an axially external wall in relation to the rim exterior. The radially internal wall, radially external wall and the wall embodied axially internally towards the rim centre are closed. The wall embodied axially externally towards the face of the rim in the radially external area is embodied as a closed rim flange oriented radially towards the inside and is open in its radially internal area. A filler ring is mounted in a radially fixed manner inside the annular chamber on the radially internal annual chamber wall. The side wall of the tire extends axially from the outside through an opening in the annular chamber wall embodied axially on the outside and towards the inside. The bead is mounted in a radially fixed manner in the annular chamber wall on the radial outside of the filler ring and is in a positive-fit contact with the radially external, axially internal and axially external, closed wall of the annular chamber, so that the bead is connected in a positive fit radially towards the outside, axially towards the outside, axially towards the inside and via the filler ring radially towards the inside with the single-piece annular chamber. The bead rests fully on the filler ring especially along its full axial length radially towards the inside and especially the bead and the filler ring completely fill out the annular chamber.

The invention is directed to a method for introducing compensating material (20) into a tire/wheel assembly (10). The compensating material is provided in a self-contained batch (30, 40) to facilitate shipping and handling. Upon insertion of the batch of compensating material within the tire and subsequent rotation of the tire, the batch disperses throughout the interior of the tire to compensate for radial and lateral force variations at the tire/road footprint of the tire/wheel assembly. The self-contained batch can take the form of an agglomerate (30), or may be sealed within a rupturable bag (40).
