Radially Actuated Drum Brake
A radially actuated drum brake for a commercial vehicle has a brake drum, an anchor housing with bearing receptacles for brake linings, at least two brake linings, which are mounted in respective bearing receptacles in an accommodation space of the brake drum, each of the brake linings having a friction lining carrier, a friction lining arranged thereon, and a pressure piece, which is arranged on an underside of the lining carrier, the underside facing away from the friction lining, and protrudes radially in the direction of the rotational axis of the brake drum through an opening in the relevant bearing receptacle. An application device is arranged on a cylinder sleeve of the anchor housing and has at least one pressing part with which the brake linings can be pressed against an inner lateral face of the brake drum in an application direction radial to the rotational axis of the brake drum. In the accommodation space, there is provided on each of the brake linings at least one restoring spring, which is supported such that it bears against an underside of the bearing receptacle of the anchor housing, and with which the relevant brake lining can be moved from a braking position, bearing against the inner lateral face of the brake drum, into a non-braking position away from the inner lateral face of the brake drum.
