ABSTRACT:
A frontal seal for tracked vehicles comprises two rings one of which slides on the other with a certain pressure exerted by resilient members coaxially mounted on each ring. The rings comprise a frusto-conical portion provided, in correspondence of the major base, with an outwardly directed radial flange, whose surface opposed to the ring body forms the friction surface of the ring, and a cylindrical portion adjacent to the frusto-conical portion and joined thereto in correspondence of the minor base thereof. The resilient members comprise an annular body which in cross section is composed by a trapezoid and a circle tangent to one of the non parallel sides of the trapezoid. In the assembled seal the portion with circular cross section is also tangent to the ring body in correspondence of the junction line between the cylindrical and the frusto-conical portions thereof.
