Definitions
- the invention relates to a clutch for a motor vehicle, such as a dry or a wet dual clutch, with two intermeshing disk packs, of which the disks of one, first disk set axially slidably but rotatably connected to a driven component and the fins of the one, second disk set axially slidably but rotatably connected to an aborted component.
- Clutches are already known from the prior art and are used in motor vehicles, u.a. used with internal combustion engines and / or electrical machines. Such vehicles may be designed as cars, trucks or other commercial vehicles.
- the invention fulfills the purpose of actuating a clutch.
- the operating principle can be used both with multi-disc clutches for dual-clutch transmissions as well as with single-clutch inserts.
- Double clutches are a power shift clutch unit consisting of two (usually coaxial) couplings that can switch connections to one shaft each.
- Examples of applications for this are clutch modules for dual-clutch transmissions, in which both clutches have independent clutch actuations and one clutch operates the odd, the other clutch the straight gears.
- the former are usually located on the inner solid shaft, the latter on the concentric hollow shaft. In this way - while one clutch currently transmits torque - the next gear can already be preselected. Subsequently, the torque is passed without interruption of traction when changing from the current to the preselected gear. This allows the traction-free drive of wheels on said vehicles.
- the slats of the wet multi-plate clutch are often routed to profile sheets.
- teeth in which engages a lamellar toothing, an axial displacement of the slats is allowed and at the same time ensures torque transmission by a positive connection in the circumferential direction.
- L—weg a distance between the respective input and output lamellae, with the clutch open by this storage of slats arises.
- this air gap also depends on the shape of the lamellae, in particular also on the shape of any grooves that serve to guide the oil, and on the oil itself.
- each lamella of the first and / or the second plate package has a Axialverschie- bungsbewirkabrough, such as a projection or a recess with an existing aborted or driven component own form-fitting portion, such as a Axialverschiebungsbewirkabêt opposite recess or elevation, is in operative connection.
- the Axialverschiebungsbewirkabites is formed on a trained as a tube with the aborted or driven component rotatably connectable or non-rotatably connected intermediate component.
- the pipe can then be torque transferring be connected to a pot, wherein the tube is displaceable relative to the pot upon initiation of an adjusting movement, such that a forced movement of the slats of one of the two plate packs is effected.
- a frictional engagement between the slats of the two plate packs can be achieved.
- Such a design allows a compact design.
- An advantageous embodiment is also characterized in that one or more of the grooves in a developed state has / have a constant pitch or a continuous / discontinuous pitch change and / or all the slots have different pitch values at the same axial position.
- an approximately internally toothed cover is detachably but non-rotatably attached to one end of the tube, for example via a screw connection.
- the torsional rigidity and load capacity of the tube can be increased. The forces to be transmitted can then be higher.
- an internally toothed lid at one end of the tube is releasably attached but non-rotatably mounted, for example via a screw connection. It is advantageous to use countersunk screws.
- one or more engaging or disengaging members such as electric motors
- cause rotation of the rotor to force axial displacement of the blades, such as at the If the pipe are equally distributed, a weight balanced and at the same time compact coupling can be achieved.
- an engagement or disengagement, via a pinion, such as a spur gear, is in operative connection with the internal toothing of the lid.
- the pinion can be straight or helical toothed. Also, a snail-like gearing makes sense. A fail-safe and low noise emitting coupling can then be realized.
- a groove in which a projection of such a blade is included which can come into frictional contact with only a single other blade at a certain axial position has a greater pitch than a nearest groove of an adjacent blade same disc pack. The slopes can then increase from groove to groove of the farther away from the former lamella fin.
- the invention preferably relates to a dry multi-plate clutch in which there are inner plates and outer plates.
- the outer disks so a specific disk set, is guided in a Nutrohr.
- the groove tube has grooves of different pitch in the circumferential direction. Depending on the axial distance to the fixed end plate, the pitch of the grooves increases.
- the lamellae have at least one pin, with which they engage in each case a groove of the groove tube and (at the same time) in an axial groove of the plate carrier.
- the slats are then moved in response to the corresponding guide groove by different amounts to each other.
- the slats are moved so that they are always equidistant from each other.
- the rotation of the groove tube can be done, for example, via an inner pinion.
- the advantage is that e.g. the slats are subject to the same wear everywhere. For this, it may be accepted that a more abrupt transition to frictional engagement, as in conventional multi-plate clutches occurs. However, this can be alleviated by appropriate suspensions of the individual slats.
- the drive can, for example, take place via a revolving electric motor, in which case the mass should be distributed as homogeneously as possible over the circumference.
- a revolving electric motor for example, two electric motor (E motors) whose CM is located in the middle of the groove tube.
- E motors electric motors
- CM CM is located in the middle of the groove tube.
- the energy could be supplied via sliding contacts.
- the basic idea is a shift of the individual slats of the drive side of the coupling depending on its axial position. The farther the slats are from the right edge of the disk pack, the faster they are delivered to the left.
- This function is carried out by a tube having different grooves with different slopes.
- Each lamella, which is guided in this pipe, runs in a special case in a separate groove.
- the groove cuts the material completely.
- the groove can also be designed in the manner of an elongate through hole.
- the slats have instead of a toothing as in classic multi-plate clutches each have a pin that runs in this groove.
- access of the grooves from the edge of the tube is possible.
- the fins could be introduced there before the grooved tube lid is attached.
- This possibility would also have the advantage of the lamella exchange, if it would be necessary in case of damage or excessive wear.
- a disadvantage would be the weakening of the stiffness of the pipe, but this can be remedied.
- the other possibility would be attachment of the pins after the fins of the grooved tube were inserted.
- This attachment could be realized by a screw, riveting or gluing. A screw is preferred.
- About one of the above types of attachment a possible disassembly would be realized by what the bolting solution would be ensured.
- the fins are also centered over the surface contact of the outer surface with the inside of the groove tube.
- the tube is closed / closed by a lid.
- the lid can be attached to the grooved tube by screwing, riveting, welding, gluing or other joining methods. Through this cover, the operation of the mechanism can be controlled. This happens e.g. as shown in the drawings explained later, via an internal toothing on which a pinion engages / engages a pinion. This can be driven electromechanically or purely mechanically. Also, a drive by means of piezo actuators is a useful alternative to drive the mechanism
- the whole system is stored in a plate carrier. This secures the lamellae against rotation through an inner longitudinal groove in which the pins of the lamellae are assigned a fixed position in the circumferential direction on the flank side.
- this plate carrier represents the storage of Nutrohres. This is completed by a lid. This is connected to the outer disk carrier by screws.
- the storage of the grooved tube in the disk carrier in the form of plain bearings or thrust washers is shown, but also rolling bearings or suitable coatings of the components are conceivable.
- a fixed lamella can be used. This has no pin and is attached to the outer plate carrier.
- the fins can be centered over a surface contact of the outer surface with the inner edge of the groove tube, as already indicated.
- a pinion can engage, which is connected to a drive.
- the outer disks of the intermediate inner disks of the output are pressed / compressed, whereby the engine torque is transmitted from the engine of a transmission.
- the corresponding slats are thus clamped by the other slats.
- the grooved tube must now be rotated in the opposite direction against the plate carrier, thus the steel plates are set back by a defined distance. This ensures the cooling of the slats by a precise determination of the Loutheasternweges and prevents or reduces the same time rattling noises due to the unwanted contact of lamellae of the input and output.
- venting behavior of the coupling can be further improved by turning the groove tube again briefly in the direction of actuation after moving apart the lamellae.
- the steel plates, which have moved the friction plates with the opening of the clutch again from this solve.
- the Lsymmetricweg between all friction surfaces of steel and friction plates is given and optimum cooling is achieved.
- the design can be designed in such a way that the slats release in the event of a malfunction, ie the power flow from the engine to the gearbox is interrupted.
- the construction is further characterized by the tube with the various slopes of the individual grooves.
- the clutch is actuated and released again.
- the grooves increase the lamellae at different axial velocities, thereby the clamping in all slats starts at the same time and torque is derived from the engine to the gearbox.
- a big problem of the conception is u.U. the power transmission from slat carriers to the slats and also from the slotted tube to the slats via a single pin.
- the load distribution could be seen as suboptimal, since the entire force is introduced to the laminar ring only at one position on the circumference. This creates a wedge effect, which could jam the slats in the grooved tube.
- the groove tube through which different release speeds of the slats, depending on their respective position, can be forced.
- the slats are selectively reset by a defined path when disengaging.
