ELECTROMAGNETIC FRICTION MULTIPLE-DISK BRAKE Russian patent published in 2019 - IPC F16D55/36 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Electromagnetic friction multiple disk brake comprises a housing, a set of alternating friction discs, a pressure disc interacting with a set of friction discs and an anchor connected to the pressure disc. Odd discs interact by means of splined slots with fixed body, there is introduced into it an undercut element of armature departure adjustment arranged between anchor and pressure plate. Two-position electromagnetic drive is installed coaxially to the anchor and envelopes it, and is made in the form of the supplying winding of the electromagnet of the magnetic conductor connected to it, the tapping winding of the electromagnet and the permanent magnet placed between the windings. Shaft is connected by means of spline protrusions with even friction disks. Shaft bearing bearings are located in the housing and fixed with a cover. Spring is connected to the anchor.

EFFECT: simplified design of electromagnetic friction multiple disk brake.
