Definitions

  • the invention relates to a component consisting of friction linings with an elastic intermediate layer based on elastomer according to the preamble of claim 1.
  • DE-C2-38 31 197 discloses a multi-layer component for transmitting a frictional force, in particular for clutches or brakes.
  • the intermediate layer attaches a friction layer to a carrier layer.
  • the intermediate layer consists of a highly reactive elastomer adhesive mixture essentially of hydrogenated nitrile rubber (HNBR) and / or a fluoroelastomer (FPM). It is connected to the adjacent layers by means of a composite binder by means of chemosorption.
  • the binder is based on modified phenolic resins and / or modified cresol resins or synthetic rubber and contains active fillers in a solvent dispersion.
  • the FPM Due to its high density of 1.6, the FPM has a negative effect on the mass moment of inertia of the component.
  • REPLACEMENT BLA ⁇ (RULE 26) From EP-A1-0 552 387 a motor vehicle clutch drive plate is known, in which elastomer blocks with a free space are arranged on a carrier plate, these elastomer blocks bearing clutch linings.
  • the elastomer blocks are provided with a Z-profile and extend in the radial direction. A targeted and defined, non-linear spring characteristic is thereby achieved.
  • Such a design of a drive plate is expensive to manufacture and assemble due to the carrier plate and the special design of the elastomer blocks.
  • the invention is based on the object of proposing a component consisting of friction linings with an elastic intermediate layer based on elastomer, in particular for clutches or brakes, which has the required resistance to dynamic loads and long-term loads.
  • a friction lining of this type is floatingly supported in the intermediate layer.
  • the elastic intermediate layer is one-layer homogeneous or one-layer interrupted by free spaces in the form of several rings or spirals.
  • the intermediate layer can also be multi-layer, see claim 7.
  • elastomers are suitable as the intermediate layer. These elastomers are selected according to the performance data for clutches or brakes or other functional parts.
  • the connection to the friction linings is stable even in the temperature range from - 40 ° C to + 275 ° C.
  • the shape of the intermediate layer is selected in accordance with claims 5 and 6 depending on the problem of use and stresses on the coverings. A continuous intermediate layer enables maximum binding forces between the friction linings.
  • a segmented layer results in increased elasticity and also additional relative movements of the friction disks relative to one another.
  • the segments of the intermediate layer can have a different elastomer base.
  • the deflection behavior of the friction linings in clutches or brakes can thus also be adjusted.
  • the friction linings can consist of different material qualities.
  • the friction and wear behavior of the friction linings can thus be adapted to the different radial sliding speeds. This increases the overall service life of the friction linings.
  • At least one inner side of the friction linings is designed to be geometrically different from the plane parallelism. In the case of a motor vehicle clutch equipped with this, the required ease of operation is present due to a smooth engagement and disengagement.
  • the spring identification of the composite or the component can be determined in a simple and cost-effective manner.
  • FIG. 16 shows a diagram with spring characteristics of a clutch disc constructed according to FIG. 7.
  • annular friction linings 1 of a component 2 are connected to one another via an elastic intermediate layer 3.
  • the intermediate layer 3 is designed as a continuous circular ring 3.1.
  • the axis of rotation of the component 2 is designated 5.
  • FIG. 3 there is a radially segmented intermediate layer 3.2. Open spaces 3.4 of approximately the same size lie between the segments 3.3.
  • an intermediate layer 3.5 is divided into individual rings 3.6 with annular free spaces 3.7.
  • the combined intermediate layer 3.8 which is only drawn in principle, has intermediate plates 4 made of a suitable material, such as steel or plastic.
  • the elastic intermediate layer 3.8 is divided into three partial layers 3.9 in accordance with the intermediate sheets 4.
  • the deflection of the component 2 in a clutch or brake, not shown, is influenced by the intermediate plates 4.
  • the deflection and the rebound is more defined or very precise.
  • Such a component 2 is therefore suitable for particularly high-stress clutches and brakes.
  • the intermediate plates 4 and the layers 3.9 are able to absorb very high loads on the friction linings 1.
  • the enlarged intermediate layer 3 of a component 20 carries two annular friction linings 7, 8 on each side.
  • the intermediate layer 3 also extends over a layer 9 in the gap 10 between the friction linings 7, 8.
  • the curve 15 is also based on the component 21 according to FIG. 7, but with a rubber quality of 40 ° shore. With this rubber quality, the travel corresponding to the axis 13 is smaller and therefore does not meet the requirement. According to curve 16, there is a very small spring travel - that is, very hard engagement. This curve 16 forms the basis of the component 2 according to FIG. 1, the rubber quality being 40 ° shore.
  • a friction lining 30 has a trapezoidal cross section with conical surfaces 31 and a plane-parallel surface 32. Between the trapezoidal friction lining 30 and a plane-parallel friction lining 35 there is an elastic intermediate layer 36. This connects the aforementioned surfaces 31, 32 and a plane-parallel surface 34 of the lining 35.
  • the cross-sectional areas of the friction linings 30, 35 and the intermediate layer 36 total cross section:
  • the width of the inside 32 is 60% of the total width 33.
  • the angle 17 is 45 °, the angle 18 is 37 °.
  • the thickness 19 is 57% of the total width 33.
  • both friction linings 37 to 39 are trapezoidal with conical surfaces 31.
  • the friction lining 39 is larger than the opposite friction lining, corresponding to its thickness 41
  • the intermediate layers are designated 42.
  • the two opposing friction linings 43 and 44 are designed symmetrically to one another.
  • conical surfaces 45, 46 and a very short plane-parallel surface 47 are provided for the component 24.
  • the friction linings 48, 49 are prism-shaped due to cone surfaces 50, 51.
  • Intermediate layers 65, 66 connect the two friction linings 45, 46 and 48, 49, respectively.
  • a conical surface 65 of a friction lining 64 is continuously straight and lies at an angle 66 of 84 ° to the axis of rotation 5.
  • An elastic intermediate layer 67 connects the friction linings 35, 64.
  • a friction lining 70 of a component 27 has a conical surface 71 only on the circumference alongside an intermediate layer 72 and the friction lining 35.
  • the intermediate layer is designated 77.
  • a friction lining 80 of a component 29 has a curvature 81 on the inside. This lies centrally to the axis of symmetry 82.
  • the curvature 81 can be displaced in the direction of the arrow 83.
  • Suitable elastomers for the intermediate layer are 3 elastomers, for example based on NBR, HNBR, FPM, EPDM, EPM, ECO and HTV silicone. It means:
  • EPDM ethylene-propylene rubber with third component
