BRAKING DEVICE WITH WEAR COMPENSATOR Russian patent published in 2000 - IPC

FIELD: machine engineering, namely braking devices with wear compensator, possibly braking systems of wheels of transport vehicles. SUBSTANCE: braking device includes piston with annular grooves on inner cylindrical surface and coaxially mounted inside it collet chuck with bead and outer teeth, release spring, sleeve and rigidly joined with cylinder rod having stop. Sleeve and release spring are arranged between bead of collet chuck and stop of rod. Sleeve is mounted with possibility of axial motion by value equal to admissible gap between piston and friction discs. EFFECT: enhanced operational reliability of braking device, its simplified design, reduced labor consumption for making it. 1 dwg
