Abstract: The invention relates to a suspension device (1; 11) intended to connect a wheel carrier (3) to a body (5) of a vehicle, the device having means (4, 8, 9) conferring to the wheel carrier, with respect to the body, a degree of camber freedom and a degree of suspension deflection freedom substantially independent of one another. The said means comprises an intermediate support (4) linking the wheel carrier to the body, the intermediate support being, on the one hand, articulated with respect to the body along a substantially vertical first axis (ASI) and, on the other hand, articulated to the wheel carrier along a second axis (R1R2), so that a rotation of the intermediate support about the first axis permits the degree of camber freedom.

Abstract: A vehicle wheel, comprising a rim, a disc, a tire defining with the rim a circumferential cavity C, and at least one resonator suitable for attenuating a natural resonant frequency of said cavity, said wheel also comprising a safety support, for supporting the tread of this tire from the inside in the event of loss of inflation pressure, said support providing at least one of the walls of said resonator. The invention also provides for the safety support comprising resonators.

Abstract: A process for demounting a tire P, and a tread-bearing support S internal thereto, from an integral mounting rim J, which comprises first and second rim seats, the two rim seats being inclined towards the outside and extended axially to the outside by projections of low height. The process includes the steps of inserting, into a lubricated gap between the toe of the first bead Bo and the corresponding rim seat, a demounting insert I in the form of a portion of a circular ring of triangular meridian section of small dimensions, and then ejecting the first bead Bo from the rim J before or simultaneously with the ejection of the tire/support assembly.
