BRAKE DISC WITH CENTRAL HUB PART Russian patent published in 2013 - IPC F16D65/12 

FIELD: motor industry.

SUBSTANCE: brake disc is made with a central hub part and a friction ring. The friction ring via spacers connects halves of the friction ring, between which there are air channels of the internal ventilation system. The central hub part of the brake disc and the friction ring are connected with at least one stop element against axial displacements and arranged radially inside the friction ring with the available receiving hole. The friction ring is radially movable in the area of the receiving hole relative to the stop element. The stop element comprises a bushing fixed with a screw on the central hub part of the brake disc, which covers the screw along the external circumference. A vehicle comprising a brake disc is made with a central hub part and a friction ring. The method to install a brake disc on the central hub part includes side displacement of the brake disc onto the wheel flange and insertion of the threaded pin from inside into through holes of the wheel flange. Then the threaded pin is fixed into slots of the wheel flange. Afterwards the threaded pin is introduced from outside into through holes of the friction ring and are screwed together with threaded pins.

EFFECT: stable kinematic closure between a friction ring and a central hub part of a brake disc, improved heat removal from a friction ring during brake disc operation.
