Circumferential well portion of a wheel rim, filled with an annular sealing joint which is provided with a valve.

摘要

The wheel rim (1), intended to be equipped with a tyre (P) of the type without an independent air chamber, is equipped with a circumferential well portion (11) contiguous with the rim (10) of the wheel rim. This circumferential well portion (11) is filled with an annular sealing joint (2) comprising a valve (3). The valve body (32) is surrounded with a sheath (21) made of vulcanised rubber whose secant modulus of elasticity under compressive force is at most equal to 0.20 times the secant modulus of compression of the vulcanised rubber comprising the sealing joint, these two moduli being measured under a relative deformation of 10%. A groove is arranged in the wheel rim for the inlet of inflating air.
