STUD PIN AND STUDDED TIRE Russian patent published in 2020 - IPC B60C11/16 

FIELD: automotive industry.

SUBSTANCE: invention relates to the automotive industry. Stud pin includes a vertex including an end surface made capable to come into contact with the road surface, and a body section configured to hold the top and the bottom flange. Shape of bottom flange profile is anisotropic, in which from imaginary rectangles that can be described around profile shape, first least rectangle and / or second least rectangle includes short sides and long sides of different length. Shape of flange profile includes four or more first projecting sections (F1) of flange, which protrude in longitudinal direction, and two second projecting sections (F2) of flange, which protrude in transverse direction. Shape of the vertex profile is a form containing rectilinear apical sections passing along straight lines. At least one of rectilinear sections of the body extends along the flange profile shape section between two adjacent protruding sections of the flange first protruding sections (F1) and the flange second protruding sections (F2) along the outer circumference of the shape of the flange profile.

EFFECT: high resistance to loss of a pin, improved braking and running properties, improved controllability on ice-covered road surfaces.
