Definitions

  • the invention relates to a gear-like device for actuating the brake shoes of a drum brake for a motor vehicle, a first and a second brake piston being axially displaceably mounted in a housing and - in the assembled state - the brake pistons effecting the corresponding actuation of the brake shoes, the brake pistons for Realization of the displacement - seen in the axial direction - via a push rod and a first gearwheel interacting with the push rod are effectively connected to one another and the first gearwheel can be driven with the aid of a second gearwheel.
  • This first gearwheel is driven with the aid of a second gearwheel, a type of pressure rod, which engages in a recess in the threaded sleeve with corresponding threads with the threaded sleeve, is then axially displaced so that the brake shoes can be adjusted or readjusted.
  • the brake pistons 3 and 4 are - seen in the axial direction - to realize the corresponding displacement via a push rod 5 and a cooperating with the push rod 5 gear 6 effectively connected.
  • the first gear 6 can be driven with the aid of a second gear 7, which will be discussed in more detail below.
  • the brake pistons 3 and 4 which are displaceably mounted in the bearing recess 11, are guided in the bearing recess 11 in a "form-fitting manner" (groove, sliding block or the like), that is to say they are not rotatably mounted here of the internal thread of the first gear 6, the push rod 5 can be moved accordingly effectively.
  • the first and second gear 6 and 7 are designed as spur gears, that is to say they have a straight toothing. 1 and 2 show clearly that the first gear 6 has a substantially greater width than the second gear 7.
  • FIG. 2 shows the state of the device 1, in which the first gear 6 is already relative to the second gear 7 has moved.

Abstract

Dispositif (1) de type transmission destiné à actionner les mâchoires d'un frein à tambour pour un véhicule. Un premier (3) et un second (4) piston de frein sont montés dans un carter de manière à être axialement coulissants et à l'état monté, les pistons (3, 4) de frein entraînent l'actionnement correspondant des mâchoires de frein. Pour la réalisation du mouvement de coulissement dans le sens axial, les pistons (3, 4) sont reliés ensemble de manière opérationnelle par l'intermédiaire d'une tige de compression (5) et d'une première roue dentée (6) en interaction avec la tige de compression (5), la première roue dentée (6) étant entraînée à l'aide d'une seconde roue dentée (7). La présente invention permet un fonctionnement optimal des mâchoires de frein et une fabrication économique, du fait que la première (6) et la seconde (7) roue dentée sont engrenées l'une avec l'autre de manière telle qu'un coulissement axial de la première roue dentée (6) est possible.
