BRAKE DRIVE WITH WEAR COMPENSATOR Russian patent published in 2010 - IPC F16D65/14 F16D65/52 B64C25/42 

FIELD: machine building.

SUBSTANCE: drive consists of cylinder, of piston installed in cylinder, of fixing device in form of conic bushing with conic insertions arranged inside piston cavity, of un-breaking device in form of an elastic element installed between conic bushing and thrust ring movably positioned on cylinder guide, rigidly tied with cylinder, and of device for retracting piston into initial position. The elastic element of the un-breaking device is made as a compression spring. The thrust ring corresponds to press-on bush with radial orifices. The conic bushing of the fixing device is installed with a minimum clearance relative to end surface made inside the piston; the clearance ensures transfer of force of the compression spring to conic insertions. The conic insertions are movably installed in radial slots of the press-on bush and generate friction force along a cylinder guide deliberately overcoming force of the compression spring.

EFFECT: reduced axial dimensions of drive and expanded functionally of brake drive due to its application in brake systems regardless from pressure value in drain lines.
