PARKING BRAKE OF REAR WHEEL WITH MECHANISM FOR MOVEMENT OF SHOES AND SUPPORT OF REAR BRAKE Russian patent published in 2024 - IPC F16D55/00 F16D65/00 B60T1/00 

FIELD: machine building.

SUBSTANCE: disclosed group of inventions relates to a passenger car brake system. Rear wheel parking brake consists of assembled support having U-shape outer and inner parts, note here that U-like ledge of outer part has ledge with through threaded hole to receive guide extending end. U-shaped shelf of internal part of support has a projection from below, in which there is a stepped hole and a through hole, located along a common longitudinal axis in a horizontal plane, note here that support outer part and U-shape support inner part are jointed together by free ends of U-shape posts in horizontal plane by means of two screws. Rear wheel parking brake pads movement mechanism consists of reverse electric motor, located on cylindrical part of stepped screw with projection and thread on opposite end, installed in hole of cylindrical piston with blind stepped hole, in which there is a stepped screw with a shaped nut fixed inside the piston against longitudinal movement and against its rotation around the axis of the piston. Piston with protruding stepped screw, on cylindrical part of which there is a thrust bearing inserted into a stepped hole of the inner part of the assembled parking brake with fixation of this position.

EFFECT: compactness, reduced dimensions, higher reliability of braking system, higher safety.
