  • the invention relates to a clutch release bearing device with an inner bearing ring, an outer bearing ring and rolling elements, which are guided by a cage and roll on provided by the bearing races raceways, the annular space located rolling elements of two, each rotatably with one of the bearing rings are connected and sealed against each other at the other bearing ring contact seals are sealed against the environment.
  • the invention is concerned with a clutch release device that withstands high running loads, even in off-road use, where increased dirt and dust loads must be expected.
  • Such a clutch release bearing device is known from DE 19503217.
  • two contacting seals are provided, of which a seal is non-rotatably connected to the outer ring and extends in the direction of the inner ring and rests on a sealing surface provided by the inner ring.
  • the other of the two contacting seals is connected via sliding piece indirectly to the outer ring and extends from the sliding piece with which it is connected in a rotationally fixed manner in the direction of a sealing surface which is provided on the outside by a flange provided on the inner ring.
  • Gap seal upstream which keeps out coarse particles and which is formed by the interaction of the flange with the sliding piece.
  • the invention has for its object to provide a Kupplungsausschreib- storage device, which is characterized by a simplified manufacturability and high insensitivity to dust, etc., without causing the heat input is increased in the camp.
  • Another object of the invention is to provide a sealing unit which, despite the self-centering properties of Kupplungsausgur- storage facility and thus unavoidable angular mobility of parts of the clutch release bearing provides a good seal against environmental influences.
  • the thrust washer can be connected in the usual way with the outer ring as by clipping, which then no longer because of the available space it would be possible if the outer ring itself or the flange of the outer ring extending in the direction of the axis of rotation would form the sealing surface of the non-contacting seal, in which the non-contacting seal would be coarse particles and the contact seal following in the direction of the rolling elements would not contain any particles from the outer ring Keeps the bearing interior away.

Abstract

L'invention concerne un palier de débrayage (1) qui dispose d'au moins un joint d'étanchéité de contact (9.2) qui protège l'espace annulaire (8) situé entre les bagues de roulement (2, 3) contre les influences extérieures. Un joint à fente (9.3) servant à séparer les particules grossières est associé au joint d'étanchéité (9.2) pour améliorer son efficacité d'étanchéité. Le joint à fente (9.3) est formé entre une rondelle (16) qui sort radialement de la rondelle de butée (14) disposée sur la bague extérieure de roulement (3), et un élément (10, 20) relié à la bague intérieure de roulement (2).
