  "textContent": "The wheel constitutes a solid of revolution about an axis ( alpha - alpha ) and is composed of a rim (A), a hub (E) and a web (C). The web is joined to the rim and to the hub by interior and exterior surfaces enabling a theoretical median line to be determined which passes through the point (P) connecting the web to the point (T) connecting the web to the hub. There are first, second and third curves linking a double inflection point, the plane of the external surface (1) of the rim being tangential to the exterior surface of the web second curve.",
