Abstract
The invention relates to an electromechanical disk brake (10). To attain brake boosting, the invention proposes embodying the disk brake (10) with a multiple brake cylinder (24), which is displaceable in a secant direction of a brake disk (20), and which has both a friction brake lining piston (22), which is displaceable transversely to the brake disk (20), and two brake booster pistons (26), disposed facing one another, which are displaceable parallel to the brake disk (20), and which are braced on fixed abutments (36), for instance on an inside of a brake caliper (12) of the disk brake (10). For actuation of the disk brake (10), the multiple brake cylinder (24) is displaced in the direction of rotation (46) of the brake disk (20), and as a result, the brake booster piston (26) that is at the front in the displacement direction moves into the brake cylinder (26) and, via the friction brake lining piston (22), presses the friction brake lining (18) against the brake disk (20). A force of friction exerted on the friction brake lining (18) by the rotating brake disk (20) presses the multiple brake cylinder (24) in its displacement direction as well and as a result boosts a pressure e…
