Description
Technical field
The present invention relates to the pressing plate of a kind of clutch for motor vehicles, such as stripper plate, intermediate plate, counter or clutch plate, it has at least one rivet housing region, and described rivet housing region is designed for accommodating rivet, can be fixed on another pressing plate by pressing plate by means of described rivet.
Background technology
This pressing plate knowledge based on enterprises is known.Friction clutch in the most known PWTN that can be applicable to motor vehicles and for the method manufacturing the clutch plate of this friction clutch.
The shortcoming of the prior art of this enterprises is: due to the making full use of and owing to being embedded in sheet material by riveting bolt and owing to the deformation of rivet does not ensure each plate plan parallelism to each other and then plate parallelism error to each other occurs of tolerance of part in the case of there is riveting parts.
Contrary known a kind of clutch with stripper plate from DE 41 42 124 A1, described stripper plate is connected with clutch case via riveting parts.In order to flywheel is spaced apart, pressing plate is installed to cover via additional disk spring.
Summary of the invention
Therefore, it is an object of the invention to: eliminate shortcoming of the prior art, and especially realize after mounting the plate being connected to each other by means of rivet being carried out recalibration, in order to set up the plan parallelism between the sheet material participated in.
This is realized by a kind of pressing plate according to the present invention.Pressing plate has at least one compliant area, and described compliant area constitutes or is embodied as so that it realizes/allows has the torsion of the pressing plate of compliant area, tilt and/or bend, in order to guarantee the two pressing plate plan parallelism to each other.The plan parallelism guaranteed in like fashion of plate reduces the required axial arrangement space of clutch unit, and this makes described clutch unit become compacter.Additionally, reduce friction loss by eliminating parallelism error.On the one hand this means less used heat, and this affects efficiency energetically, and on the other hand this and then cause longer life-span of clutch unit.In addition plan parallelism can contact along with the optimal face bringing two plates, and thus friction fit can transmit higher power.
Hereinafter claim advantageous embodiment and illustrate in detail below.
Therefore, it is possible to advantageously: riveting mouth is included in rivet housing region, and rivet can be encased in described rivet opening, and wherein compliant area is seamlessly connected on rivet housing region.In like fashion, the compliant area that can stand plastic deformation during recalibration is disposed directly near rivet housing region.This can be favourable, because rivet housing region is usually the following region of pressing plate, described region can cause occurred plan parallelism error and this plan parallelism error the most only to extend on the shortest region of pressing plate.Ensure in like fashion: the region being re-calibrated plan parallelism is the most maximum.
Additionally, compliant area can have special geometry or perforation or material behavior so that realize/allow the torsion relative to the platen region different from compliant area and rivet housing region, tilt and/or bend.Therefore, the function of compliant area can be geometrically and/or to realize in the way of material science.This improves the motility of the present invention, because it can differently realize according to service requirement and manufacture method.
Additionally, compliant area can have special material behavior so that compared with the region being adjacent to compliant area of pressing plate, use the material of different materials and/or different hardness.Therefore it is possible that: power expend relatively small in the case of reverse targetedly, tilt and/or twisted plate, described plate has the highest intensity to meet its function.Expend, with little power, the recalibration carried out and improve the efficiency of installation process.Additionally, do not damage the face that function is important for friction fit.
The rivet housing region of plate also is able to be configured to connect sheet.In like fashion, corresponding plate all has less diameter in any position not being mounted with connection sheet.This less weight causing element and material cost saving.
Can be advantageously: connect sheet and be fixed on the remainder of pressing plate via the attachment areas forming/limit compliant area in connecting sheet embodiment.In like fashion, the connection needed for transmitting for power can undertake the function of compliant area simultaneously.This causes optimum utilization structure space.Additionally, this embodiment realizes effectively reversing, tilt and/or bending of plate, can move easily with respect to plate in attachment areas because connecting sheet.
In addition it is possible that: the geometry of compliant area is embodied as so that constitute contraction flow region, recessed circle, groove and/or thin section.Therefore, corresponding plate has bigger radial surface in compliant area, thus reduces the surface tension of local.Therefore, the recalibration of plate is feasible in the case of little power expends.Whereby also due to the straightening force reduced improves the efficiency of installation process.
Being furthermore possible to advantageously, perforation is configured to hole, such as reach through hole or blind hole.Therefore, being capable of the function more effectively dispelled the heat in addition to recalibration function, this overcomes the danger of clutch overheat, described overheated can deleteriously affect material and friction fit.
In addition it is possible that: hole has the extension of elongated extension, especially arc, and described extension preferably follows ring circumferential direction.Therefore, despite the presence of hole, radially the least rubbing surface is only abandoned in local, and this does not damage required friction fit and realizes eliminating parallelism error simultaneously.
It is furthermore possible in ring circumferential direction, one after the other arrange the elongated hole of multiple arcs, preferably arranges with the spacing that the center away from the pressing plate being configured to counter or stripper plate is identical.This layout realizes: provide sufficient compliant area in the case of elongated hole height is less.
Additionally, elongated hole can all have identical and that preferably observation holding is identical on ring week height, described height radially measures.This unified elongated hole height realizes the favourable manufacture of elongated hole, and this affects the manufacturing cost of whole clutch element energetically.
Additionally, the elongated hole disposed in ring circumferential direction can be provided as slit.In like fashion, the minimum change of shape by compliant area can cause the torsion of pressing plate, tilts and/or bend, because compliant area extends on long face.
The elongated hole being configured to slit can be alternately arranged by the connection part of radial outer region with pressing plate in ring circumferential direction.Therefore, also ensure that the enough intensity of pressing plate despite the presence of gratifying flexible nature and be sufficiently used for transmitting the area of frictional force.
Compliant area can be implemented as so that its geometry with there is no the geometry of pressing plate of compliant area only in the board plane of plane, distinguish the most in the axial direction.Therefore, the shape flexibility of element can be improved in the case of the holding of axial arrangement space is identical.
Can propose in other words: the solution of the present invention is: realize soft interface/compliant area onboard, described interface/compliant area realizes follow-up straightening process/recalibration procedure.
Additionally, the soft connection part of riveting sheet can be provided with in extrusion plate on pressing plate.The pressing plate of double clutch can be connected to each other via rivet via those riveting sheets.In order to compensate parallelism error, sheet material can be mutually shifted to a certain degree via soft connection part.To this, the present invention proposes straightening process additional after riveting.Here, pressing plate is assembled in straightening tool in parallel with each other, parallel power is applied at least in the region of soft connection part by described straightening tool subsequently along the direction coaxial relative to rivet.
