Beschreibung
Zusammenfassung:	A seal assembly (1) configured to prevent/limit the entry of external contaminants into a motor compartment (15) of a motorised wheel (2) for vehicles (6) is described. The seal assembly (1) comprises a first support ring (16) which is fixed, a second support ring (17) which is rotatable and radially outermost of the first support ring (16), and an annular seal (18) interposed between the support rings (16, 17) and including an anchor portion (27), attached to the second support ring (17) and at least a first and a second annular sealing lip (30, 31), protruding cantilevered from the anchor portion (27), mounted by interference between the support rings (16, 17), defining a sealing configuration, wherein they cooperate with distinct portions (24, 20) of the first support ring (16) along respective annular contact lines (L), and set by centrifugal effect in a detaching configuration from the respective portions (24, 20) of the first support ring (16) at speeds of the motorized wheel (2) greater than a predetermined non-zero value (V).
