- the guide sleeve is deformed elastically to form corresponding restoring forces.
- the restoring forces provide for a return deformation into an initial or rest position.
- the guide sleeve according to the invention now has the advantage that at least a part of the rigid connection of a rigid guide sleeve merely converted into frictional heat Work is now converted into potential energy that can be fed back in direction of reversal and / or a change in the input or Ausgurkraft- level of the entire device, at least in part.
- the guide sleeve according to the invention can be used in particular in actuators for friction clutches, in particular double clutches to improve the hysteresis or the controllability of the usually automated actuator, as an all-too rigid connection and support of the guide sleeve within the clutch during actuation frictional forces at the interface between the guide sleeve and actuation system results.
- the frictional losses associated with the frictional forces lead to a deterioration of the hysteresis and thus to a deterioration of the controllability of the double clutch.
- the fastening part (i) has a nozzle-like connecting portion, via which the fastening part is connected to the tubular guide part, and (ii) arranged on the side facing away from the guide part of the connecting portion mounting portion, wherein the elastically formed portion of nozzle-like connecting portion and / or is formed by the attachment portion.
- the elastically formed region is preferably formed either by the connection-like connection section or by the attachment section. If the elastically formed region is formed by the nozzle-like connecting section, then the connecting section is formed, for example, as an elastically deformable flexible pipe socket.
- the elastically formed region or at least one of the elastically formed regions is formed as a corrugated pipe-shaped region of the fastening part.
- the corrugated-tubular region can then be designed as a mounting flange.
- the elastically formed region or at least one of the elastically formed regions is formed by at least one resiliently formed lug (a spring lug).
- the attachment portion of a plurality of radially more or less far outwardly facing projections is formed, of which at least one resiliently designed as this tab is formed.
- the projections are largely independent of each other on Connection section arranged. Compared with the design of the attachment portion as a mounting flange, the embodiment can be regarded as an arrangement of such projections as a deliberate introduction of recesses for "weakening".
- the fastening part has at least one helical spring forming the elastically formed area or at least one of the elastically formed areas, via which the at least one fastening means is connected to the remainder of the fastening part.
- This rest is then formed, for example, as a mounting flange.
- the rohrformige guide member and the fastening part are formed as a common one-piece part.
- the parts can be connected to one another in a materially bonded manner.
- the at least one fastening means is a means for a screw, so for example a screw or stud bolt with thread.
- this has a guide sleeve which is formed as above-mentioned guide sleeve.
- the common embodiments and the general function of clutch actuation devices for friction clutches are known from a variety of patent applications and other documents of the applicant. As an example, reference should be made to the aforementioned DE 10 2008 047 170 A1.
- the clutch actuating device is preferably a clutch actuating device for a dual clutch.
- the clutch actuating device is, for example, a clutch engagement device or a clutch release device.
- the clutch actuating device has at least one means of the guide sleeve directly or via an intermediate element axially guided input and / or Ausgurlager.
- the Kupplungsbet2011i- device of a dual clutch then usually has two such input and / or release bearing.
- FIG. 2 shows the guide sleeve shown in Fig. 1 in another illustration
- FIG. 3 shows a guide sleeve for a clutch actuating device according to a second preferred embodiment of the invention
- FIG. 4 shows a guide sleeve for a clutch actuating device according to a third preferred embodiment of the invention.
- FIG. 1 shows a guide sleeve 10 for a clutch actuating device (not shown) of a friction clutch designed as a double clutch.
- the guide sleeve 10 comprises two essential parts 12, 14, namely a tubular guide part 12 and a fixing part 14 axially adjoining the guide part 12 with respect to a main axis 16 of the guide sleeve 10, which is designed as a radial extension of the tubular guide part 12.
- Guide member 12 and mounting member 14 are formed as a one-piece component. However, it would also be conceivable in principle to form the guide part 12 and the fastening part 14 from two or more parts. This results in an axial breakthrough through the complete guide sleeve 10, which usually receives in a double clutch as nested shaft and hollow shaft (not shown) transmission input shafts of the corresponding dual-clutch transmission.
- the fastening part 14 shown in turn comprises a nozzle-like connecting portion 18, via which the fastening part 14 is connected to the rohrformigen guide member 12, and on the guide member 12 remote from the side of the connecting portion 18 arranged mounting portion 20.
- This mounting portion 20 is in the example shown of several radially more or less far outward protrusions 22, 24 are formed, via which the guide sleeve 10 on a (not shown) housing part or other coupling part of the friction clutch by means of fastening means shown in FIG. 2 fixed to the housing (or fixed in the coupling) are fixed can.
- the projections 22, 24 are formed in the example shown by resiliently formed tabs (spring tabs) 28.
- projections 22, 24 mounted in the coupling guide sleeve 10 is supported on a surface of the coupling part from where it is attached, so for example, the said housing part.
- Some of the projections 22 have channels 30 for receiving the fastening means 26, while others of the projections 24 do not.
- the channels 30 define those intended for the fasteners 26 Positions on the fastening part 14.
- On the outer circumference 32 of the tubular guide part 12 a plurality of axially aligned guide webs 34 are formed.
- the resiliently formed tabs 28 form elastically formed areas between the tubular guide part 12 and the positions provided for the fastening means 26 positions on the fastening part 14. These elastically formed areas, so in the example of FIG. 1, the resiliently formed tabs 28, allow a displacement of the guide member 12th with attached guide sleeve 10, so an elastic deformation of the guide sleeve 10 in the region of the fastening part 14, too.
- the tabs may be made of an elastically deformable material such as e.g. Plastic be formed.
- the corresponding displacement of the guide member 12 may be rotational and / or translational nature, so it may be when moving to a tilting as well as a displacement of the guide member 12.
- the guide sleeve 10 in the region of the fastening part elastically (resilient) designed. This elasticity is tailored to the overall system of the actuator.
- the aim of this additional elasticity is to convert the friction work introduced when the clutch actuating device is actuated not only into frictional heat but also into elastic strain-changing work. In the case of a reversal of direction and / or a change in the input or Ausgurkraftmakerss this stored energy can then be returned to the system in parts. Exactly this return of the deformation work helps the overall system of the clutch actuator to a better Hysterese- or control behavior.
- FIG. 2 shows the guide sleeve 10 shown in FIG. 1 in a representation from a different angle, wherein now also the fastening means 26 are shown.
- the fastening means 26 are inserted into the channels 40 provided for this purpose in the projections 22.
- FIGS. 3 and 4 show further embodiments of the guide sleeve 10, which in
- the guide sleeve 10 shown in FIG. 4 largely corresponds to the guide sleeve 10 of FIG. 3, but has no elastically formed connecting portion 18.
- the fastening part 14 additionally has coil springs 40 forming the elastically formed regions, via which the fastening means 26 are connected to the remainder of the fastening part 14 (namely the fastening flange 38).
- the fastening part 14 is at least partially elastic and allows a displacement of the guide member 12 with the guide sleeve 10 attached.
- the same functions of the elastically formed regions result and, as a result, the same advantages as well.
- the elastically formed regions are thus formed by resiliently formed lugs 28 and / or corrugated-shaped regions 36 and / or helical springs 40.
