- the housing 50 has a first one Housing part 51, also referred to as the engine-side wet room capsule, and a second Housing part 51, also referred to as the engine-side wet room capsule, and a second Housing part 51, also referred to as the engine-side wet room capsule, and a second Housing part 51, also referred to as the engine-side wet room capsule, and a second
- Housing part 52 also referred to as the transmission side wet room capsule, on. These are connected by means of a flange 53 with the interposition of a housing seal 54 tightly together.
- the flange 53 has a passage opening 55 or a plurality of passage openings 55, with which the housing 50 and thus the dual clutch 1 is mounted on a structure of a vehicle shown in FIG. 10, for example on a transmission housing 56 of a tractor.
- the base plate carrier 16 is mounted by means of a rolling bearing 57 relative to the first housing part 51.
- FIG. 1 shows that the second housing part 52 has bushings 58 for the adjusting pins 38 and 43.
- the adjusting pins 38, 43 are guided in the axial direction through in each case a passage 58, so that they act on the roller bearings 37 and 42 on the respective actuating lever 20 and 21 in the interior of the housing 50 and by means not shown in the figures, in known Way eg for dry double clutches used to be actuated from outside the housing 50.
- the adjusting pins 38, 43 are sealed in the respective passage 58 by means of O-seals 59.
- the rolling bearing 57 is formed as a sealed bearing.
- the second housing part 52 is sealed by means of a Simmerings 60 against the drive shaft 1 1.
- the base plate carrier 16 is sealed by means of a Simmerings 61 opposite the PTO shaft 6.
- the second housing part 52 further has a passage for an oil feed 62 and a drain for oil drainage 63 (see, for example, in FIGS. 8A, 8B).
- 80 ° C warm for example from the oil sump of the transmission, is due to the rotation of the recorded in the housing 50 clutch components, such as the PTO shaft 6, the drive shaft 1 1, the plate carrier 4 and 9 and the moving parts, distributed in the interior of the housing 50, for example, thrown radially outward.
- the oil thereby wets the disk packs 8 and 13, which heat up during operation of the clutch, and cool them.
- the oil drain 63 is provided at the radially lowest point of the housing 50, so that in a groove 64 accumulating and heated by operation of the clutch oil can be easily removed from the housing 50, for example to the oil sump of the transmission.
- the oil flow through the double clutch is shown in FIGS. 8A and 8B.
- the assembly of the dual clutch 1 on the vehicle is shown in principle in FIG. 10.
- the dual clutch 1 accommodated and mounted in the housing 50 is mounted on the transmission housing 56 of the vehicle by being bolted thereto via the flange 53.
- the designed in the form of appropriate interfaces ends of the adjusting pins 38, 43 are connected to the vehicle provided conventional release.
- the bow spring damper unit 24 is brought together with the double clutch 1 via the example formed as a spline 23 teeth.
