Abstract

A drum brake, in particular for a utility vehicle, has a brake drum, which is rotatably mounted about a rotational axis, and multiple brake shoes, which are mounted in a receiving area of the brake drum and each of which has a friction lining support and a friction lining arranged thereon. The brake shoes can be pressed against a brake drum casing inner surface, which is designed as a friction surface, in a radial direction relative to a rotational axis of the brake drum. The interior of the drum brake is equipped with a brake cylinder assembly which is rotationally fixed to an armature housing for actuating the brake shoes. A respective pressing wedge is arranged on the friction lining support face facing away from the friction lining. The pressing wedge lies on a wedge mechanism which can be moved in a parallel manner relative to the rotational axis of the brake drum. The wedge mechanism can be moved from a non-braking position into a braking position by moving the service brake piston of the brake cylinder assembly in a parallel manner relative to the rotational axis of the brake drum.
