Description

Clutch

Technical field

The present invention relates to a kind of clutch being particularly useful for motor vehicle.

Background technique

The clutch being particularly useful for motor vehicle has multiple part, and described part is partly connected to each other.At this, it is especially effective that the application of rivet element turns out to be, because described rivet element can more simple shape be installed and however still cause lasting connection compared with screw connection.This rivet element is such as known by DE102011011916A1.

Certainly, the rivet element used also can regard as additional component, and described additional component must be purchased, provides and install, and this means the cost with associated that expends of associated.

Summary of the invention

The object of this invention is to provide a kind of clutch, described clutch simplifies and reduction in cost about installation relative to prior art.

Described object realizes by the feature of claim 1.

One embodiment of the present of invention relate to a kind of clutch with first clutch element and second clutch element, wherein first clutch element has opening and second clutch element has tongue, wherein first clutch element and second clutch element are connected to each other to, tongue is joined in opening, and the region of stretching out through opening of tongue is plastically out of shape.Realize thus, the first and second clutch elements can connect by form from one another ordinatedly when not having add ons.

At this, especially advantageously, first clutch element has the gap as opening.Thus, the tongue tip of the tongue be made up of sheet material can be incorporated into well in gap and can be fixed by plastic deformation.When gap is only greater than tongue tip slightly, the little distortion of tongue tip just can be enough to fix the connection between two clutch elements.

Also it is appropriate that second clutch element has relative to the outstanding tongue tip of backstop, described tongue tip can be incorporated into until backstop in opening or gap, and wherein tongue tip is stretched out from opening with the portion of exceeding.By the backstop on second clutch element, limit tongue tip insertion depth and tongue tip can not join in opening too far.

In one embodiment of the invention, advantageously, tongue tip is divided into two tongue alar parts along the longitudinal direction, and in order to be fixed in the opening by tongue, two tongue alar parts are along contrary direction or along identical Direction distortion.Therefore, two tongue alar parts bend along contrary direction as two adjacent connecting sheets, make it directed relative to the directed approximate right angle ground of unbent tongue and abut on first clutch element.Thus, the connection of reliable form fit is realized.

Especially advantageously, tongue tip transversely direction comprises one or two side direction gap, tongue tip is out of shape on a side or on its multiple side to be fixed in the opening by tongue.Therefore, tongue tip can be out of shape in front part, namely in the region of tongue tip, the shape and the region at the rear portion of tongue tip can remain unchanged.The region of distortion, in this especially preferably deformable, makes the side camber of tongue tip and then realizes the connection of form fit.Gap is positioned at this, make it on the height roughly corresponding to the thickness of the material of first clutch element, to such an extent as to the region of stretching out gap of tongue tip is stretched out from opening with the opposite side of tongue tip in gap when being incorporated in opening by tongue.Thus, tongue tip can in gap opposite side distortion and two clutch elements can connect to form fit in a straightforward manner.

At this, especially advantageously, tongue tip c shape ground, s shape ground or the distortion of l shape ground.This realizes advantageous by following manner: one or two side of tongue is out of shape.

Also advantageously, tongue is rolled in its end regions stretched out through opening, makes to there is widening portion, and described widening portion is increase relative to the size of opening.Thus, by means of simple rolling process, the connection of the form fit between clutch element can be realized.

Embodiment

Fig. 1 illustrates the first clutch element 1 with the protuberance 2 extended laterally, in described first clutch element, be provided with opening 3.Opening 3 is configured to gap at this, described gap forming along first clutch element 1 in a lateral direction at protuberance 2.

Fig. 2 illustrates second clutch element 4, and described second clutch element is configured to have tongue 5.Tongue 5 has tongue tip 6, and described tongue tip reduces in width relative to the bottom 9 of tongue 5.The described reduction of width realizes via convex shoulder 7, and described convex shoulder is also used as backstop and is separated the bottom 9 of tongue tip 6 with tongue 5.

Tongue tip 6 is divided into two tongue alar parts 10,11 by means of gap 8.At this, gap 8 extends along the extension of tongue 5 in the embodiment of fig. 2 or is parallel to the longitudinal axis extension of tongue 5.

In figures 3 and 4, the tongue tip 6 of the tongue 5 of second clutch element 4 is inserted in the opening 3 of first clutch element 1.At this, the tongue alar part stretched out relative to opening of tongue tip 6 bends along contrary direction, make tongue tip 6 by its tongue alar part 10,11 planar abut in first clutch element 1 protuberance 2 on and cause the connection of the form fit between first clutch element 1 and second clutch element 4.

Fig. 5 illustrates second clutch element 20 with an alternative embodiment of the invention, and described second clutch element is configured to have tongue 21.Tongue 21 has tongue tip 22, and described tongue tip reduces in width relative to the bottom 23 of tongue 21.The described reduction of width is carried out via convex shoulder 24 equally as in fig. 2, and described convex shoulder is also used as backstop and is separated the bottom 23 of tongue tip 22 with tongue 21.

Tongue tip 22 is by means of a gap or as shown in fig. 5 be divided into anterior tongue region 27 and the tongue region 28 at rear portion by means of two gaps 25,26 like that.At this, anterior tongue region 27 comprise the tip freely 29 of tongue tip 22 and the tongue region at rear portion towards the bottom 23 of tongue 21.

Being positioned at this and being chosen to of gap 25,26, makes the spacing between backstop 24 and gap 25,26 roughly correspond to the thickness of the material of the protuberance 2 of first clutch element 1.Therefore, tongue tip 22 joins in opening 3, and wherein said gap is stretched out from opening a little.Thus, anterior tongue region can be out of shape, to be connected with second clutch element 2 by first clutch element 1.

The distortion of the tongue 21 of second clutch element 20 is carried out in fore tongue region 27 in the region of the side 30,31 of tongue tip 22 at this.The longitudinal axis that described side is arranged essentially parallel to tongue 21 bends.Can propose at this, only a side 30 or two sides 30,31 bend.Visible in figure 6, two sides 30,31 bend in s shape.As an alternative, two sides 30,31 also can bend in c shape.As an alternative, also only can bend by a side 30 or 31, make to occur the profile roughly in l shape.Fig. 7 illustrates the side view of the device according to Fig. 6.

Fig. 8 illustrates another embodiment of second clutch element 40, and described second clutch element is configured to have tongue 41.Tongue 41 has tongue tip 42, and described tongue tip reduces in width relative to the bottom 43 of tongue 41.This reduction of width realizes via convex shoulder 44, and described convex shoulder is also used as backstop and is separated the bottom 43 of tongue tip 42 with tongue 41.

In figures 9 and 10, the tongue tip 42 of the tongue 41 of second clutch element 40 is inserted in the opening 3 of first clutch element 1.At this, tongue tip 42 exceed and to stretch out the part of opening rolled, make the transverse slot of tongue tip be connection that is that widen and then that produce form fit.

Clutch element is preferably pressing plate, belleville spring, clutch cover, spring, transportation safety device etc. at this.Clutch is single clutch or double clutch at this, as especially friction clutch.
