Electromechanical drum brake

Abstract

An electromechanical drum brake for a motor vehicle. The electromechanical drum brake includes a drum, in which brake shoes are disposed, and an adjusting device, which is disposed between the brake shoes and driven by a drive unit, using which the brake shoes can be spread apart for braking. The adjusting device includes a rack driven by the drive unit, is floatingly mounted between the brake shoes and is in engagement with a coupling gear that acts on a first brake shoe via a push rod connected to it. An actuating rack which acts on a second brake shoe is in engagement with the coupling gear on a side of the coupling gear opposite to the rack, and the coupling gear can move freely on the rack between the brake shoes so that force differences that occur between the brake shoes can be compensated by rotating the coupling gear.
