Definitions

  • DE-OS 2124008 discloses a holder for one or more springs acting on an axially displaceably arranged component, in particular for the return springs acting on a ring piston of a friction clutch or brake which can be acted upon by pressure medium.
  • a one- or multi-part, in cross-section double-angle trained support member is provided to support the spring, which is inserted with a leg in a recess of a groove of a stationary component and on the other leg, the spring rests directly or via intermediate links.
  • the sheet metal sleeve is held in the housing by means of a bayonet closure or a bayonet mount.
  • piston fingers engage for actuation of the switching element between the fingers of the diaphragm spring, which leads to an extremely compact design in an advantageous manner.
  • Figure 1 A schematic sectional view of
  • Figure 2 A perspective view of an embodiment of the sheet metal sleeve, which is required for the arrangement of the plate spring.
  • the piston of the switching element 3 is denoted by 1 and the plate spring 2.
  • the diaphragm spring 2 is arranged such that the fingers the plate spring 2 protrude through crowns in the housing 4 and on a metal sleeve 5, which is held in the housing 4 of the switching element 3, rest.
  • the sheet metal sleeve 5 is held in the housing 4 by means of a bayonet closure or a bayonet holder 6.
  • the housing 4 has grooves; the sheet metal sleeve 5 is preferably formed as a bayonet ring and has a plurality of projections which are insertable into the housing side provided grooves and locked by turning.
  • a possible embodiment of the metal sleeve 5 is the subject of Figure 2, which shows a part of the sleeve 5, wherein the projections are provided with the reference numeral 9.
  • the outer diameter 7 of the plate spring 2 is applied to the piston 1 of the switching element. As already explained, grab the piston fingers 8 for actuating the switching element between the fingers of the plate spring 2 therethrough.
  • the invention provides an arrangement of the plate spring of a switching element is provided, which takes up little space and results in a low wear for the piston.
