Bellows seal for pivot joints, especially in automobiles

Abstract

The invention relates to a bellows seal for pivot joints, wherein a first end of the bellows is tightly and rigidly connected to the joint housing. The second end of the bellow tightly and annularly surrounds a tappet and has a radial and sealing surface. Said surface is a front face divided into an inner concave ring surface and an outer concave ring surface. In relation to the axis of the bellow, the angle of inclination of the ring surfaces is approximately α=70° for the external ring surface and approximately β=80° for the inner ring surface. The radial extension of the outer ring surface is approximately 12% in relation to the radius of the outer ring surface of the ring flange of the second end of the bellow.
