Definitions

  • the invention relates to a hydraulically actuable clutch release device for use on a motor vehicle clutch assembly, such as a dry friction clutch, with a housing having at least one attachment portion for attachment to a clutch housing, with a fixed to the housing guide sleeve and a relative to the guide sleeve axially displaceable release bearing, for actuating a clutch actuator.
  • a motor vehicle clutch assembly such as a dry friction clutch
  • DE 19746538 A1 discloses a release system for a vehicle friction clutch, consisting of a piston-cylinder unit, wherein an annular piston is guided displaceably in the cylinder, and the end side of the annular piston a release bearing is fixed, which is supported by a compression spring force applied to the friction clutch.
  • Such clutch release are used in motor vehicles, such as cars or trucks, in particular in connection with an internal combustion engine drive whose torque derived via a crankshaft is converted in a transmission.
  • a clutch In order to enable the connection of different gear stages, usually a clutch is used.
  • Known clutches are, for example, wet clutches or dry clutches.
  • dry clutches are widely used and in newer generations of clutch units, especially for double clutches, used and affected here.
  • the housing of the clutch release is then mounted rotationally fixed to the internal combustion engine fixed element.
  • the screws usually attack screws on mounting straps of the housing.
  • the screws in turn are attachable to the clutch bell housing.
  • the release bearing of the clutch release in particular its outer ring, presses when actuated on an actuator which causes an opening and / or closing of the dry friction clutch.
  • the movement of the outer ring of the release bearing is generated in the axial direction, pressure is generated in a pressure chamber of the clutch release, so that both a seal, as well as an annular piston is moved in the direction of the release bearing.
  • the clutch release device 1 also has a release bearing 10, which has an outer ring 11 which is rotationally coupled by an antifriction bearing 12 in operative contact with an inner ring 13.
  • the inner ring 13 in turn is impressed on an annular piston 14 which is mounted translationally displaceable on a lateral surface 15 of the guide sleeve 4.
  • a preload spring 16 is supported directly or indirectly on the annular piston, for instance via a preload spring bearing ring. This preload spring 16 is therefore at least indirectly in operative contact with the inner ring 13. While the one side of the preload spring 16 is supported on the annular piston 14 in the vicinity of the inner ring 13, the other side of the preload spring 16 is supported on the second portion 6 of the housing 2.
  • the first section 5 has a pressure chamber 17, which is closed by a ring piston seal combination 18 pressure-tight on one side.
  • This annular piston seal combination 18 comprises, on the one hand, the annular piston 14 and, on the other hand, a seal 19.
