Eine Trommelbremse (1), insbesondere für ein Nutzfahrzeug, weist eine um eine Drehachse (D) drehbar gelagerte Bremstrommel (2) auf, mehrere in einem Aufnahmeraum (22) der Bremstrommel (2) gelagerte Bremsbacken (3) mit einem jeweiligen Reibbelagträger (32) und einem an diesem angeordneten Reibbelag (31), wobei die Bremsbacken (3) radial zu einer Drehachse (AD) der Bremstrommel (2) an eine als Reibfläche ausgebildete Mantelinnenfläche (21) der Bremstrommel (2) anpressbar sind, wobei in einem Innenraum der Trommelbremse (1) eine an einem Ankergehäuse (8) drehfest angeordnete Bremszylinderanordnung (4) zur Betätigung der Bremsbacken (3) vorgesehen ist.
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.
