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

Abstract: A seal assembly for sealing the compartment between a rotating member and a fixed element. The seal assembly comprises a first ring fixed to the rotating member, a second ring fixed to the fixed element, and a seal element. The seal element is carried by the second ring and is connected to said second ring by means of a fitted portion; the seal element comprises at least one annular pad having an annular seal edge. The annular seal edge projects towards a coupling portion of the first ring and is adapted to cooperate with the coupling portion along a substantially linear area of contact. The seal element further comprises a spring portion adapted to exert an elastic force on the annular pad so as to push the annular seal edge towards the coupling portion.

Abstract: A gasket for sealing a compartment between rotating and fixed members. The gasket has a first ring; a second ring radially more external than the first ring; a first annular elastomeric element carried by the first ring and defining at least a first annular sealing lip cooperating with the second ring to counter the passage of external contaminants inside the compartment; a second annular elastomeric element carried by the second ring and defining at least a second annular sealing lip cooperating with the first ring to counter the passage of lubricant to the outside; a third ring coupled to the second ring and extending from this latter towards the axis of the gasket; and at least a third annular sealing lip, overhangingly projecting from the first elastomeric element and cooperating with the third ring to counter the passage of external contaminants from the outside towards the first sealing lip.

Abstract: A gasket for sealing a compartment between a fixed and a roto-translatory member. The gasket has a metal support ring adapted to be connected to the fixed member; first sealing means in a position adjacent to a first ambient containing lubricant and defining two first annular sealing lips axially spaced to cooperate with the roto-translatory member and to counter the passage of lubricant/external contaminants between the first ambient and a second ambient connected with the outside; and second sealing means axially interposed between the first sealing means and the second ambient and defining a second sealing lip axially spaced from the first annular sealing lips and adapted to cooperate with the roto-translatory member to counter the passage of external contaminants towards the first sealing lips; the first sealing means comprise two first distinct sealing rings, axially arranged side by side and respectively carrying a relative first sealing lip.
