SIDE BEARING Russian patent published in 2011 - IPC B61F5/14 

FIELD: transport.

SUBSTANCE: invention relates to railway transport. Side bearing includes the base with annular projection and guide projection, upper plate with annular projection located above the base and telescopically connected to annular projection of the base and having flat surface to interact with the car body, and central projection arranged on its lower surface. Also, device includes friction insert with central through hole, which is arranged between the base and upper plate with possibility of pressing the latter to some part of the car body, heat insulator made from polyester material with glass filler having low heat conductivity and high impact strength. Heat insulator is arranged between upper surface of friction insert and lower surface of upper plate and has cavities with open top and built-in part to arrange and grip one end section of friction insert. Device is equipped with additional heat insulator located between lower surface of friction insert and base. The main and additional heat insulators are made so that the ratio of thickness of additional heat insulator to thickness of the main heat insulator is 1:4-1:2. Guide projection of the base has the possibility of gripping and arranging the other end section of friction insert for forced fixture of position of the main heat insulator and friction insert relative to each other.

EFFECT: improving reliability and enlarging service life.
