A bead exerciser system for an automated wheel assembly may include a center lift configured to lift a wheel assembly off of a conveyor belt, a drum roller configured to rotate the wheel assembly, a pair of pinch rollers driven by a driver and configured to apply force to a tire of the wheel assembly, a force sensor configured to detect a force of the tire against the pinch rollers, and a controller configured to receive the force from the force sensor and generate a command for an alert in response to the force falling outside of a predefined threshold range.

Apparatus and method for mounting a tire on a wheel rim and/or for removing a tire from a vehicle wheel rim. Such an apparatus is usually known as a tire changer. The tire changer of the present invention is capable of verifying that the position of the inflation valve and/or of the TPMS sensor of the wheel, relative to the position of the portions of tire most subject to stresses and/or relative to the position of the mounting/demounting tools, as well as the intensity of such stresses, lie within ranges defined as acceptable. The result of such verifications is then made available via a suitable report document.

A tire changer apparatus for the assembly or disassembly of tires from a rim of a wheel of a vehicle, said tire changer apparatus comprising: a base; a drive unit movable along a predetermined direction and configured to rotate, around a rotation axis, a wheel of a vehicle; a frame emerging from the base. The rotation axis of the wheel and the predetermined direction define an ideal plane of movement of the drive unit. The apparatus also comprises a first and a second device, each of which comprises: an arm hinged to the frame and configured to rotate around a respective axis parallel to the rotation axis of the wheel, a tool configured to operate on a rim and/or a tire of a wheel; the first and second devices are configured to arrange the respective tools on opposite sides with respect to said ideal plane.

A jaw (1) for clamping a wheel rim comprises a body (2) extending along a longitudinal orientation (L). The body (2) includes: a connecting portion (22) configured to be connected to the head of the wheel-holder unit; a base portion (21) extending along the longitudinal orientation (L); a first abutment wall (23) extending from the base portion (21) along a clamping orientation (R); a second abutment wall (24) extending from the base portion (21) along the clamping orientation (R) in a spacing-apart direction (VA) and longitudinally spaced from the first abutment wall (23) by a working distance (DL); an abutment surface (251), longitudinally interposed between the first abutment surface (23) and the second abutment surface (24) and including a first portion (251A) and a second portion (251B, 251C), disposed at an advanced position relative to the first portion (251A) in the spacing-apart direction (VA) of the clamping orientation (R) to come into contact with the wheel rim. The second portion is spaced from the first abutment wall (23) along the longitudinal orientation (L) by a first abutment distance (D1), greater than 30% of the working distance (DL).
