Regulator for brake-shoe gap

The utility model relates to a regulator for a brake-shoe gap, which is composed of a front and a back actuating rods, a release spring, an outer cone sleeve assembly, elastic cone sleeves, stroke regulating springs and an outer barrel sleeve. The utility model is characterized in that a set of elastic cone sleeves are contacted on the back actuating rod under the start of the initial pushing or pulling acting force of the front actuating rod through the front actuating rod and one outer cone sleeve assembly fixedly connected with the front actuating rod, the back actuating rod is moved forwards or backwards under the combined actions of the stroke regulating springs arranged between the set of elastic cone sleeves, and therefore, the braking gap of the braking brake shoe of a railway vehicle is controlled. The regulator for brake-shoe gap has the advantages of simple structure, low manufacturing cost and rapid, reliable and effective stroke regulating action.
