Description
Technical Field
The invention relates to a secondary cylinder for a clutch or brake of a motor vehicle, comprising: at least one axially displaceable engaging/disengaging bearing having a bearing sleeve for transmitting a force onto a pressure tank for axially displacing the pressure tank; and an adjustment disk interposed between the bearing sleeve and the pressure tank. The invention further relates to a clutch having at least one axially displaceable pressure tank which is pressurized by a control disk of a secondary cylinder.
Background
The secondary cylinder and the separating system are already known from the prior art. For example, EP 2205883B 1 discloses a slave cylinder, which is designed in particular as a CSC (clutch slave cylinder) for a hydraulic system of a motor vehicle, having a housing in which a piston is arranged axially displaceable between end positions within a pressure chamber, wherein the pressure chamber is sealed by two sealing elements having different diameters, and the piston is operatively connected via a control rod to a release bearing, which is prestressed by means of at least one energy accumulator arranged in the pressure chamber, wherein the sealing element having the larger diameter is axially fixed by an annular magnet, which is provided for detecting the stroke length or position of the piston.
However, the prior art always has the following disadvantages: the control disk/adjusting disk/shim disk for actuating the pressure tank is not fixed in the installation position on the engagement bearing. It is therefore loosely located on the engagement bearing and is only radially centered via the bearing. Since the fixing of the adjusting disk is not carried out during the mounting process, incorrect handling and incorrect assembly can easily occur during transport due to loosening or slipping of the adjusting disk.
Disclosure of Invention
It is therefore an object of the present invention to avoid or at least reduce the disadvantages of the prior art. In particular, a flexible transport safety device for the control disk should be developed. Incorrect assembly, for example due to loss of the adjusting disk during transport, is to be avoided. The aim of the invention is therefore also to simplify the installation process and to avoid sources of errors.
The object of the invention is achieved in such a device according to the invention by: the transport securing device, which is positively engaged on the bearing sleeve, acts radially outward with a bias on the control disk, so that the control disk is centered relative to the bearing sleeve.
This has the following advantages: the adjusting disk can no longer be lost during transport, so that the installation is simplified. Thus, a transport securing device for a simple mounting of the control disk on the bearing sleeve is achieved.
Advantageous embodiments are explained in detail below.
It is also expedient for the transport securing device to provide an axial stop for the bearing sleeve in order to preclude axial movement of the transport securing device relative to the bearing sleeve. In this way, it is advantageously ensured that relative movements between the transport securing device and the bearing sleeve are excluded. Since the adjusting disk is also axially fixed relative to the transport securing device, axial movements between the bearing sleeve and the adjusting disk can also be ruled out by the transport securing device. The bearing sleeve can be configured not only as a bearing inner ring but also as a bearing outer ring.
It is also advantageous if the transport securing device has a latching section for fastening to the bearing bush. In this way, the transport securing device can be simply pushed onto the bearing bush, as a result of which the latching hook is elastically deformed until it engages behind a projection or a section of the bearing bush in its final installation position. Thus, a simple clamping of the transport safety device can be achieved.
It is also advantageous if the latching section is designed such that it cannot be released accidentally (by itself), but at the same time is easily detachable.
It is also advantageous if the latching section is designed as a hook which points predominantly in the radial direction, i.e. as a hook which projects perpendicularly to the axial direction of the bearing sleeve and/or of the transport securing device. The latching portion can thus engage behind a surface of the bearing sleeve which is formed perpendicular to the axial direction, for example the axial end side, particularly simply.
It is also expedient for the latching section to form an axial stop to prevent relative movement between the transport safety device and the bearing bush.
A further advantageous embodiment is characterized in that the transport securing device is designed as a transport securing sleeve made of tinplate and/or as a securing plate. This achieves that the transport safety device has a low weight and can be produced at low cost.
It is also advantageous if the transport safety device has one or more longitudinal cutouts or recesses, since this reduces the rigidity, in particular in the radial direction, so that the elasticity of the transport safety device can be increased. Thus, an easier insertion of the transport safety can be achieved.
It is also advantageous if a prestressing section is formed on the side of the transport securing device facing the pressure tank, said prestressing section prestressing the actuator disk radially and/or axially. In this case, it is particularly advantageous if the pretensioning section is designed such that the adjusting disk is pretensioned radially outward. It is also advantageous if the adjusting disk is axially prestressed in the direction of the bearing bush. The adjusting disk is thereby preloaded such that it cannot fall out of the bearing sleeve or the coupling bearing during transport.
It is also expedient if at least three teeth are present on the side of the transport securing device facing the pressure tank, said teeth acting radially outwardly against the adjusting disk, for example by: the teeth are located uniformly distributed over the circumference on the inner edge or the radial inner side/inner face of the perforated adjusting disk.
It is also expedient for the teeth to project obliquely to the axial direction and obliquely to the radial direction and to be prestressed outwards and/or in the axial direction away from the pressure tank. It is thereby possible to apply pretensioning also to adjusting disks of different thicknesses. In this case, the greatest pretensioning is applied in particular when the adjusting disk is the thickest. The thicker the adjusting disk, the further outward the contact of the transport securing device with the adjusting disk occurs on the teeth.
Furthermore, it is advantageous if the transport securing device is designed such that, in the installed state, it abuts the adjusting disk at a contact point in a plane perpendicular to the axial direction. The transport securing means thus rests on a circular contact line against the inner edge on the inner diameter of the annular adjusting disk.
It is also advantageous if the contact point between the control disk and the transport safeguard moves with increasing thickness of the control disk (and/or with increasing inner diameter) toward the outer region of the transport safeguard (i.e. the region close to the pressure tank). I.e. the contact point moves radially outwards (and/or axially towards the pressure tank, i.e. away from the bearing housing). By virtue of the oblique design of the prestressing segments or teeth, the same transport securing device can advantageously be used for control disks of different thicknesses. The transport securing device thus makes it possible to compensate for different thicknesses of the adjusting disk.
It is also advantageous if the bearing bush has a centering shoulder for the adjusting disk on its side facing the pressure tank, preferably radially on the outside, for example in order to contact the adjusting disk on its outer circumferential surface. A particularly stable seating of the adjusting disk is thus ensured, since the adjusting disk can be applied not only radially on the outside, but also pressed from radially on the inside to radially on the outside by the transport securing device.
It is also advantageous if the bearing sleeve has a pressure transmission surface for bearing against an axial end face of the adjusting disk. The force of the bearing sleeve acting in the axial direction is thereby transmitted to the control disk and via the control disk to the pressure tank.
It is also advantageous if the transport safety device is produced without cutting, in particular stamped, preferably from a spring plate, for example from a hardened spring plate. This makes it possible to obtain a good coordination between the particularly advantageous transport safety device and the transport safety device which is sufficiently rigid, i.e. exerts a sufficient pretensioning force, and which can be produced in a simple manner.
The rigidity of the transport safety device can be increased even if one or more radial pretensioning of the region of the transport safety device that is in contact with the adjusting disk or other regions has a pretensioning-increasing geometry. The pretensioning force of the transport securing device, in particular of the teeth, is thereby increased in an advantageous manner.
It is also advantageous if the prestressing geometry is preferably designed as a continuous circumferential collar, for example between the tooth and the latching hook.
It is also advantageous if the Slave Cylinder is part of a hydraulic Slave Cylinder/CSC (Clutch-Slave-Cylinder), in particular a dual CSC.
The object of the invention is also achieved by a clutch, for example a single clutch or a dual clutch, having at least one axially displaceable pressure tank which is pressurized by the control disk of the secondary cylinder according to the invention.
In other words, the invention relates to a transport safety device for engaging a regulating disk of a bearing. The transport securing device, which is designed as a transport plate/holding plate, is latched to the bearing, in particular the bearing sleeve, by means of latching hooks. By means of the radial pretensioning of the transport securing device, fluctuations in the thickness of the adjusting disk can be compensated. In addition, it is possible in the case of small fluctuations in the bell range (Glockenma β) to be able to coordinate the Clutch and the Clutch Release System (CRS) with one another already before the entire System is delivered in the case of maintenance. Therefore, measuring components in the workshop or during installation are no longer necessary.
The transport securing device is designed as a notched component in the form of a crown (Krone). On one side there is one (or more) snap-in hook(s) which fix/secure the transport safety on the joint bearing. On the other side, a crown is present which applies a radial pretension to the adjusting disk in order to be able to compensate for different adjusting disk thicknesses and in order to fix the adjusting disk (in the axial direction and in the radial direction) on the bearing. In order to additionally strengthen the transport safety, a flange profile can be added in the middle, preferably in the axial direction of the transport safety.

Detailed Description
Fig. 1 shows a secondary cylinder 1 for a clutch or brake of a motor vehicle. The secondary cylinder 1 has at least one axially displaceable engagement bearing 2. In this embodiment, the sub-cylinder 1 is a sub-cylinder for a dual clutch. The secondary cylinder 1 therefore has two axially displaceable engagement bearings 2 for operating one clutch each. The joint bearing 2 has a bearing sleeve 3 in order to transmit forces to the pressure tank 4 and to displace it axially. By axial displacement of the pressure tank 4, the relevant clutch is operated.
Furthermore, the secondary cylinder 1 has an adjusting disk 5, which is inserted between the bearing sleeve 3 and the pressure tank 4. The adjusting disk 5 is designed to adjust the pretension for operating the pressure tank 4. That is to say, the thicker the adjusting disk 5, the greater the pretension that is exerted on the pressure tank 4. The adjustment of the thickness of the adjusting disc 5 is also used to compensate for manufacturing tolerances. Furthermore, a transport securing device 6 is present, which engages in a form-fitting manner on the bearing sleeve 3 and pretensions the control disk 5 radially outward, so that the control disk 5 is centered relative to the bearing sleeve 3.
Fig. 2 shows a side view of the slave cylinder 1. The secondary cylinder has two joint bearings 2, of which there are an outer joint bearing 7 and an inner joint bearing 8, which is arranged concentrically and radially inside the outer joint bearing 7. The two joint bearings 2 have the same configuration. Thus, the configuration of one joint bearing 2 is exemplarily described, which corresponds to the configuration of the other joint bearing 2. In the joint bearing 2, the bearing sleeve 3 serves as a bearing inner ring 9. Additionally, a bearing outer ring 10 is present in each case. Rolling elements 11 are inserted between the bearing inner ring 9 and the bearing outer ring 10.
Fig. 3 shows the secondary cylinder with the mounted adjusting disk 5 and the mounted transport safety 6. Fig. 4 and 5 show an enlarged view of the area of the slave cylinder 1 on which the adjusting disk 5 rests. The adjusting disk 5 rests on an axial end face of the bearing sleeve 3. The adjusting disk 5 has an annular body of constant thickness. By means of the thickness of the adjusting disk 5, the pretensioning of the pressure tank 4 can be influenced and production-dependent tolerances can be compensated. In order to fix the adjusting disk 5 for transport, the transport securing device 6 is clipped onto the bearing sleeve 3 and the adjusting disk 5.
The transport securing device 6 has an annular sleeve-like configuration. A plurality of longitudinal cuts 12 according to the type of recess 13 are introduced in the longitudinal direction of the transport safety device 6, said cuts being arranged at uniform intervals in the circumferential direction. The longitudinal cut 12 separates the latching hooks 14, which are arranged distributed over the circumference, from one another on one axial side of the transport securing device 6, i.e. on the side facing away from the pressure tank or toward the bearing bush. The latching hook 14 has a latching portion 15, which is designed as a hook pointing radially inward. In the mounted state, the latching portion 15 engages behind the region of the bearing sleeve 3, so that it rests against the bearing sleeve 3 by means of an axial stop 16 formed on the latching portion 15. The transport securing device 6 is thereby axially fixed relative to the bearing sleeve 3. When the transport securing device 6 is pushed axially into the engagement bearing 2, the latching section 15 is guided by the radially inner side of the bearing sleeve 3. Thereby, the latch hook 14 is elastically pressed inward. In the installed position, the latching hook 14 is undeformed and the latching section 15 is hooked in the axial direction behind the bearing sleeve 3.
The longitudinal cutouts 12 separate circumferentially distributed teeth 17, which serve as prestressing segments 18, from one another on the other axial side of the transport securing device 6, i.e. on the side facing the pressure tank or facing away from the bearing bush. The teeth 17 project obliquely to the axial direction of the transport safety device 6 and obliquely to the radial direction, preferably at an angle of 30 ° to 45 ° relative to the axial direction. The teeth 17 project radially outward in this case. Since the teeth 17 are pressed with their radial outer side from the radial inner side onto the adjusting disk 5 in the mounted state, the adjusting disk 5 is prestressed radially outward and in the axial direction by the teeth 17 in the direction of the bearing sleeve 3. The adjusting disk 5 cannot therefore be removed from the bearing sleeve 3 by the pretension exerted by the teeth 17.
The transport securing device 6 can be used for differently thick adjustment disks 5, since the teeth 17 are designed as obliquely projecting sections. The thicker the actuator disk 5, the greater the pretension that is exerted by the transport securing device 6 on the actuator disk 5.
A centering shoulder 19 is formed on the bearing sleeve 3, which protrudes in the axial direction on the radial outside of the bearing sleeve 3 toward the adjusting disk 5. The centering shoulder 19 is contacted by the adjusting disk 5 on its outer circumferential surface 20. The axial end face of the bearing sleeve 3 serves as a pressure transmission surface 21 against which the axial end face 22 of the adjusting disk 5 bears in the mounted state and via which a force is transmitted for axial displacement.
An increased pretensioning geometry 23 is formed on the transport securing device 6 according to the type of the flange 24. The reinforcing geometry 23 is arranged in the region of the tooth 17 or in the region between the tooth 17 and the latching hook 14 of the transport securing device 6.
