Abstract: An assembly including a deformable, inextensible tread-bearing support S, which can be slipped on to a suitable rim bearing surface (11). The bearing surface (11) extends axially towards the inside of a first rim seat (13null), which is in turn extended to the outside by a protrusion or hump (15null) of low height. The first rim seat (13null) is inclined towards the outside. A second rim seat (13null) having, viewed in meridian section, a generatrix, the axially inner end of which is located on a circle of diameter DnullA greater than the diameter of the circle on which is located the axially inner end DnullA of the first rim seat (13null). The two seats being, axially to the inside, extended by frustoconical portions (17, 14) of a height at least equal to 0.01 times the minimum diameter of the bearing surface (11), and the generatrices of which form with the axis of rotation angles null at least equal to 45null. The rim bearing surface (11) is provided with at least one circumferential protuberance (115) arranged in a circumferential groove (30) of the radially inner face of the tread bearing support S, such that the protuberance (115) axially comes to bear and butt up against at least one lateral wall of the groove (30).

Abstract translation: 包括可变形的不可伸展的胎面支承件S的组件，其可滑动到合适的轮辋支承表面（11）上。 轴承表面（11）轴向延伸到第一边缘座（13'）的内部，第一边缘座（13'）又由低高度的突起或隆起（15'）延伸到外部。 第一轮辋座（13'）向外倾斜。 在子午线部分中观察到的第二轮辋座椅（13“），母线的轴向内端位于直径D”A的圆上，该直径大于圆的直径，其中轴线内 第一轮辋座（13'）的末端D'A。 所述两个座部沿轴向向内延伸，其截面圆锥形部分（17,14）的高度至少等于所述支承表面（11）的最小直径的0.01倍，并且所述母线与所述旋转轴线形成 角度α至少等于45°。 轮辋轴承表面（11）设置有至少一个周向突起（115），其布置在胎面支承支撑件S的径向内表面的周向凹槽（30）中，使得凸起（115）轴向承受，并且 与凹槽（30）的至少一个侧壁对接。
