- FIG. 1 shows an actuating device according to the invention for a double clutch with two
- FIG. 2 shows an enlarged detail from FIG. 1.
- an actuating device 1 for actuating a double clutch which comprises two partial clutches, which are actuated by means of the Betätigüngsvorraum 1.
- the double clutch is mounted on a housing 2, which is also referred to as a clutch bell and a housing part 3 includes.
- the transmission input shaft 4 is designed as a solid shaft and rotatably disposed in the transmission input shaft 5, which is designed as a hollow shaft.
- the transmission input shaft 5 is rotatably mounted in the housing part 3 by means of a gear bearing 8, which is also referred to as a transmission input bearing.
- the transmission bearing 8 is designed as a rolling bearing with an inner ring 9 and an outer ring 10. Between the inner ring 9 and the outer ring 10 rolling elements, for example balls, are arranged in a known manner.
- the outer ring 10 of the gear bearing 8 is arranged in a complementary executed recess of the housing part 3 and thereby supported in the radial direction.
- the inner ring 9 of the gearbox bearing 8 surrounds the transmission input shaft 5. In this case, the inner ring 9 may be fixed by a press fit on the transmission input shaft 5.
- actuating the two partial clutches of the double clutch serve two actuating systems 11, 12, each comprising an actuating piston and an actuating bearing.
- the actuating piston of the two actuating systems 11, 12 are guided by means of a guide device 15 axially displaceable.
- Axial means in the direction or parallel to the common axis of rotation of the two transmission input shafts 4, 5.
- the actuation system 11 further comprises an actuation lever 21, which represents, for example, one of a plurality of actuation levers belonging to a plate spring-like actuation lever device.
- the actuating lever 21 is supported via a bearing 24 on the housing part 3.
- the bearing 24 is arranged in the radial direction outside the two transmission input shafts 4, 5. As a result, more space is available to stiffen the operating lever 21.
- the guide means 15 comprises a support member 30 from which fastening arms 32 extend radially outward
- the fastening arms 32 start from a support body 34 and serve to support the support member 30, for example by means of Screw fasteners or Nietharms instituten to attach to the housing part 3.
- the attachment arms 32 are integrally connected to the support body 34.
- Supporting element 30 is designed as a sheet metal part and has a greater wall thickness than a guide element 40, which is also designed as a sheet metal part.
- the guide element 40 comprises a guide sleeve body 42, from which a step body 44 extends radially outward.
- the step body 44 has, in longitudinal section seeks a radial leg which is angled away from the guide sleeve body 42. In turn, an axial leg of the step body 44 is angled away from the radial leg.
- the axial leg of the step body 44 is integrally connected via a connecting body 46 with a sealing flange 48 which extends on the guide member 40 radially outwardly.
- Centering projections 47, on which the guide element 40 is centered on the outer ring 10 of the gearbox bearing 8, are formed on the connecting body 46 on its side facing the gearbox bearing 8.
- the sealing flange 48 which extends radially outward from the connecting body 46 of the guide element 40, defines a receiving space for a static seal 50.

In the opposite axial direction, that is to the left in FIG. 2, the gearbox bearing 8 is supported on the support element 50 with the interposition of the connecting body 46 of the guide element.
- the step body 44 of the guide element 40 defines a receiving space for a radial shaft sealing ring 60.
- the radial shaft sealing ring 60 has a sealing lip, which bears against the outside of the transmission input shaft 5.
- the sealing lip is based on a support body which has an angular cross section and rests against the step body 44.
- the guide sleeve body 42 is radially spaced from the transmission input shaft 5 so that it can rotate freely relative to the guide sleeve body 42.
- the guide element 40 is fastened to the housing part 3 with the aid of the support element 30, which is screwed to the mounting arms 32 on the housing part 3.
- the free ends of the support body 34 are, with the interposition of the connecting body 46 of the guide member 40, under bias to the outer ring 10 of the gear bearing 8, that a biasing force of about ten kilo Newton is applied to the transmission bearing 8.
- a preload is applied to the static seal 50 by the support member 30 via the guide member 40.
- the division of the guide function on the guide member 40 and the support function on the support member 30 provides, inter alia, the advantage that for the guide member 40 and the support member 30 different sheet thicknesses can be used.
- the guide element has, for example, a wall thickness of approximately 1, 2 millimeters. This relatively small wall thickness is sufficient, since the guide element 40 essentially serves only for centering the guide element 40 itself and for the axial guidance of the actuating pistons of the actuation systems 11, 12.
- the support member 30 is in contrast made of a much thicker sheet metal material to support operating forces of up to ten kilo Newton in the axial direction.
- the guide element 40 rests on the gearbox bearing 8 and is centered on the stationary outer ring 10 of the gearbox bearing 18. This ensures a good fit of the radial shaft sealing ring 60 to the transmission input shaft 5.
- the support member 30 presses with the support body 34 on the diameter of the
