FLEXIBLE ADAPTER AND RIM ASSEMBLY FOR A ROLLING ASSEMBLY

Assembly of a rim () and of a flexible adapter (), intended to make up, with a tire (), a rolling assembly, the rim () having a mounting well () that is extended axially by a boss (), a substantially frustoconical rim seat () and a rim flange () that extends the rim seat () axially on the outside, with a bearing face of substantially radial orientation, the adapter having an axially inner end () intended to rest on the rim seat (), an axially outer end () and a substantially cylindrical body () that connects the axially inner end () and the axially outer end () and is intended to receive, in cooperation with the axially outer end, a tire bead (), characterized in that the substantially frustoconical rim seat () of said rim has an inclination (α) relative to the axis of rotation DD′ of between −2 and +6 degrees, said angle (α) being counted as positive when the virtual vertex S of said substantially frustoconical seat is situated axially on the outside.
