Definitions
- the invention relates to a bearing arrangement for mounting a slave cylinder on the cover of a clutch, in particular for a motor vehicle.
- Clutches are operated according to the prior art with concentric slave cylinders which are supported by the clutch cover, wherein between the clutch cover and slave cylinder, a bearing is arranged to rotatably support the clutch relative to the slave cylinder.
- the slave cylinder is received with a cylindrical outer surface of the bearing inner ring radially inward and the clutch cover takes with a cylindrical opening the bearing outer ring radially inside.
- An embodiment of the invention relates to a bearing assembly for supporting a slave cylinder on the cover of a clutch, in particular for a motor vehicle, arranged with a concentric to the rotational axis of the clutch slave cylinder, wherein the slave cylinder is carried by the clutch cover of the clutch, wherein between the clutch cover and the slave cylinder Bearing is arranged to rotatably support the clutch relative to the slave cylinder, wherein the slave cylinder has a cylindrical outer surface which is received radially inwardly from a bearing inner ring of the bearing and the clutch cover is formed with a cylindrical opening which a bearing outer ring of the bearing radially receives inside, wherein the bearing outer ring radially outwardly has a step and the clutch cover has radially inwardly an L-shaped portion having a radially extending first leg and extending in the axial direction of the second Schen kel, wherein the clutch cover rests with its first leg and with its second leg to the bearing outer ring. This will cause a radial and achieved
- the second leg has a chamfer or a recess, so that only a portion of the leg rests against the bearing outer ring.
- air can enter between the outer ring of the cover bearing and clutch cover, because a distance is ensured.
- a defined force is introduced into the bearing ring.
- the second leg bears against the bearing outer ring over the entire length of the second leg.
- the introduction of force into the bearing ring can be defined by defining the length of the second leg.
- the bearing has a rolling body with a center axis aligned in the radial direction, wherein the abutment region of the bearing outer ring and the first leg is arranged on one side of the central axis, wherein the second leg extending in the axial direction only on the side of the central axis rests against the bearing outer ring, on which also the contact region of the first leg is arranged.
- a defined introduction of force is effected in the bearing ring, which lies on one side of the central axis.
- the bearing has a rolling element with a center axis aligned in the radial direction, wherein the abutment region of bearing outer ring and first leg is arranged on one side of the central axis, wherein the second leg extending in the axial direction extends to the side extends the central axis and rests against the bearing outer ring, which is on the other side, as the contact region of the first leg.
- defined force discharges are effected in the bearing ring, which lie on both sides of the central axis.
- the bearing is an angular contact ball bearing.
- the slave cylinder having extending inner ring surface, wherein the slave cylinder rests on full axial length of this inner ring surface of this. It is also expedient if the slave cylinder has a stop element protruding in the radial direction, on which the bearing inner ring is supported in the axial direction.
- slave cylinder is formed with a piston-cylinder unit for actuating a clutch.

- the clutch is preferably a friction clutch with at least one axially displaceable pressure plate.
- the clutch is a double clutch with two displaceable pressure plates, wherein the slave cylinder 2 has two axially displaceable piston 4.5 two piston-cylinder units, which are arranged concentrically to each other.
- the pistons 4, 5 are arranged in a housing 6 of the slave cylinder 2. Radially outside the housing 6, a bearing 7 is arranged, which has a bearing inner ring 8 and a bearing outer ring 9 and roller bodies 10 arranged therebetween.
- the bearing 7 is with its bearing inner ring 8 on a cylindrical portion 1 1 or a cylindrical outer surface of the housing 6 of the slave cylinder 2 is pressed.
- the bearing inner ring 8 abuts the region 11 approximately over its entire axial length.
- a ring 13 is received as an axial stop, wherein the ring 13 protrudes in the radial direction of the cylindrical portion.
- the bearing 7 is an angular contact ball bearing. However, it may alternatively be another bearing.
- the slave cylinder 2 is arranged concentrically to the axis of rotation of the clutch or to the transmission input shaft. Also, the slave cylinder 2 is carried by the clutch cover of the clutch, wherein between the clutch cover 3 and the slave cylinder 2, the bearing 7 is arranged to support the clutch rotatable relative to the slave cylinder.
- the cylindrical outer surface 1 1 of the slave cylinder 2 is radially inwardly received by the bearing inner ring 8 of the bearing 7, wherein the clutch cover 3 is formed with a cylindrical opening 14 which receives the bearing outer ring 9 of the bearing 7 radially inside.
- the bearing outer ring 9 has radially outside a step 15. Furthermore, the clutch cover 3 has a radially L-shaped portion 16 on the inside, with a first leg 17 extending in the radial direction and with a second leg 18 extending in the axial direction, which can be clearly seen in FIGS. 2 and 3.
- the clutch cover rests with its first leg 17 and with its second leg 18 on the bearing outer ring 9.
