Embodiment
The present invention studies the adjustment of the liner geometrical shape to friction facing, to improve the bursting strength of friction facing. Friction facing has the moulding of annulus substantially, and described annulus has the ring cross section of rectangle.
Friction facing has interior diameter and outside diameter. Between the outside diameter and interior diameter of friction facing, cross section compared little, it is possible to no longer obtain desired bursting strength.
When cross section compared little, the stress occurred in friction facing can become high so that causes the less desirable explosion of friction facing. Thus, the overall function of the clutch plate being equipped with friction facing is impaired significantly.
According to an aspect of the present invention, friction layer keeps identical in its size. In order to improve bursting strength, according to the present invention's only expandable carrier layer. The expansion of carrier can radially-inwardly and/or radially outward carry out.
In addition, convex shoulder or additional liner volume is axially added in order to improve bursting strength. Convex shoulder or additional liner volume are for realizing abrasion deposit. Should be ensured by abrasion deposit: can not cause blocking or adhering to of pressing plate.
Fig. 1 to 3 illustrates friction facing 1 simplifiedly; 20; Three embodiments of 30. Identical Reference numeral is used to represent identical or similar part. Hereinafter, friction facing 1 is first inquired into; 20; The common ground of 30. Set forth friction facing 1 subsequently; 20; Difference between 30.
Friction facing 1; 20; 30 comprise carrier layer 3 and friction layer 4 respectively. Friction layer 4 is using side that it deviates from carrier layer 3 as surface of friction 5.
Arrow 6 represents the thickness of carrier layer 3. The thickness of friction layer 4 is represented by arrow 7. The thickness 7 of friction layer 4 represents possible Wear layer thickness simultaneously. Represent that the abrasion of maximum possible is together with all tolerances by arrow 8. Friction facing 1 is represented by long and short dash line 10; 20; The rotation of 30 or axis or longitudinal center line.
The interior diameter of surface of friction 5 and outside diameter remain unchanged relative to traditional surface of friction. According to an aspect of the present invention, surface of friction 5 interior diameter inner radial and/or in the structure space that the radially outer of outside diameter exists if desired for radially carrier layer 3.
Thus produce in friction layer 4 at least one around convex shoulder. The height of convex shoulder or the degree of depth are advantageously greater than when considering all tolerances for the abrasion deposit required for each friction facing. Around convex shoulder can be arranged on inner radial and/or the radially outer of friction layer 4.
In the friction facing 1 that figure 1 illustrates, carrier layer 3 has radial extension 11. The extension 11 of the radial direction of carrier layer 3 extends radially inwardly. Represent that radial extension is great relative to traditional friction facing by four-headed arrow 12.
Radial extension 11 and carrier layer 3 have identical thickness or height. The stretching, extension axially of carrier layer 3 is called thickness or height. Axially refer to along the direction of rotation or longitudinal center line 10 or it is parallel to rotation or longitudinal center line.
The interior diameter of the carrier layer 3 with radial extension 11 is represented by arrow 13. Traditional interior diameter of carrier layer 3 is represented by arrow 14. Represented the outside diameter of friction facing 1 by arrow 15, described outside diameter is constant. Friction layer 4 and carrier layer 3 have identical outside diameter 15.
In friction facing 20 shown in figure 2, radial extension 21 extends radially outwardly. At this, with Fig. 1 the difference is that the interior diameter of friction facing 20 is constant. The liner diameter of the institute's surplus in carrier layer 3 is represented by four-headed arrow 22.
Represented the outside diameter of friction layer 4 by arrow 23, described outside diameter is corresponding to the outside diameter of traditional carrier layer. The outside diameter of the increase of the carrier layer 3 with radial extension 21 is represented by arrow 24.
The friction facing 30 that figure 3 illustrates has the extension 31 extended radially inwardly and the extension 32 extended radially outwardly. In friction facing 30, it is combined with the extension of the radial direction illustrated in fig 1 and 2. The surplus in the outside diameter of carrier layer 3 is represented by four-headed arrow 33.
Represented the outside diameter of friction layer 4 by arrow 34, described outside diameter is corresponding to the outside diameter of traditional carrier layer. The outside diameter of the increase of the carrier layer 3 with radial extension 32 is represented by arrow 35.
The interior diameter reduced of the carrier layer 3 with radial extension 31 is represented by arrow 36. Represented the interior diameter of friction layer 4 by arrow 37, described interior diameter is corresponding to the interior diameter of traditional carrier layer.
Fig. 4 to 6 illustrates the clutch plate 60 in loading state with pressing plate 40 simplifiedly. Clutch plate 60 comprises two friction facings 41,42, and described friction facing is also referred to as half friction facing. Friction facing 41 is corresponding to the friction facing 1 that figure 1 illustrates. The diad that friction facing 42 extends about the radially direction between these two friction facings 41 and 42 is symmetrical relative to friction facing 41.
The loading state of friction facing 41,42 only elaborates about the friction facing 1 in Fig. 1 hereinafter. But rim condition is identical for the friction facing 20 and 30 in Fig. 2 and 3 so that the additional observation to the friction facing 20 and 30 in loading state can be saved.
These two friction facings 41,42 have the extension 47,48 of the radial direction extended radially inwardly respectively in its carrier layer. The thickness of carrier layer is represented by arrow 43. The thickness of friction layer is represented by arrow 44. Friction facing 41,42 torsionally with from Moving plate 46 is connected by means of spring section 45.
By spring section 45, these two friction facings 41 and 42 are axially pre-tight away from each other.
The interior diameter of the friction layer of friction facing or half friction facing 41 and 42 is represented by arrow 49. The interior diameter reduced of the friction facing 41,42 with radial extension 47,48 is represented by arrow 50. The outside diameter of friction facing 41,42 is represented by arrow 51.
Figure 5 illustrates the friction facing 41 in the state worn and torn completely. The wear-thickness of friction layer is represented by arrow 54. When wearing and tearing completely, friction layer is approximate to wear and tear completely.
In figure 6 details VI in Figure 5 shows: in the state that the friction layer of friction facing 41 weares and teares completely, between pressing plate 40 and the extension 47 of radial direction, still remain with little spacing 56. Thus ensure: though pressing plate 40 when friction layer weares and teares completely also not extension 47 with the radial direction of carrier layer contact. Friction facing 41,42 thus can be advantageously avoided less desirable to block relative to the institute of pressing plate 40.
