Abstract
An expanding device for actuating one of the brake shoes of a drum brake includes a body of revolution and transmission bodies actuated by the body of revolution via ball track ramps. A spacer body is located between two partial bodies of the body of revolution, the spacer body guided by an adjustment spring keeping the partial bodies at the respectively reached distance. The spacer body is screwed onto a pin on the first partial body. A readjustment nut ensures that, when the two partial bodies are pushed apart, the spacer body rotates on the pin and moves away from a supporting surface on a partition of the second partial body. Upon renewed actuation of the brakes, the readjustment nut is guided such that the spacer body bears against the second partial body, but takes up a different position on the pin, the position corresponding to the air clearance readjustment.
