DISC BRAKE WITH PARKING BRAKE MECHANISM Russian patent published in 2006 - IPC F16D65/56 

FIELD: transport mechanical engineering.

SUBSTANCE: disc brake can be used in wheel brake systems of transportation vehicles with automatic compensation of wear of contact surfaces of shoes and disc. Disc brake has disc with shoes, hydraulic cylinder with sealing ring and piston, which piston interacts with one shoe and which connected cinematically with parking brake drive by means of rod mounted coaxially in cavity of piston. Disc brake also has balls disposed uniformly along circle of piston. Balls are placed into separator for interaction with cone-shaped surface made outside rod and with internal surface of piston; the surfaces form wedge-shaped space. Separator is made for longitudinal movement along rod and it is compressed motionlessness against glass with cup, which glass is fixed in case of hydraulic cylinder. There is clamping spring in the cup. Glass with cup is mounted in cavity made at end of rod.

EFFECT: simplified design; reduced labor input; improved reliability operation; reduced pressure losses of brake fluid.
