- the invention relates to a friction ring suitable for a synchronizing device of a transmission circuit, which friction ring has a metallic main body and a friction lining located thereon. Likewise, the invention relates to a method for producing such a friction ring. Background of the invention
- a friction element for a synchronizer in particular a shift sleeve transmission, is known for example from DE 10 2010 053 947 A1.
- the friction element is part of a friction pad system.
- a synchronizing ring in which friction lining pads are arranged.
- the synchronizer ring serves as a carrier or cage.
- the production of the formed as pads friction linings can be done by means of a pressing tool. In this case, cavities are embedded in a mold plate, which determine the shape of the pads to be produced.
- the shaped pads are then cured in an oven and are then dimensionally stable without further mechanical processing. Alternatively, a grinding of the pads may be provided as an additional processing step.
- a multi-layered friction lining is known. Layers of this particular for braking devices provided friction lining can be inserted in the form of a film in a mold or produced in Schüttpressvon, the use of a film over the bulk pressing the advantage of a well-defined layer thickness ke has.
- the production of a friction lining directly on a base body is known in principle from DE 39 07 443 C2 and from DE 10 2007 041 218 A1.
- the object of the invention is to further develop a friction ring which is suitable, in particular, for a synchronizing device of a transmission circuit with respect to the cited prior art with regard to rational manufacturability, long-term durability and also in the mass production of closely tolerated product properties.
- the friction ring has a metallic base body, in particular made of sheet steel, as well as a friction lining located thereon.
- the friction lining is formed directly on the surface of the body of a thermosetting Schüttpressmasse, so that a prefabrication of the friction lining is eliminated.
- Another advantage is that the friction lining seamlessly covers a surface of the metallic main body and in this case a positive connection between a toothing formed directly by the main body and the friction lining produced thereon is produced.
- the surface of the friction lining can be smooth.
- Synchronization devices of transmission circuits operating with friction rings according to the invention can be designed, for example, as a 1-cone system, as a 2-cone system, and as a 3-cone system.
- a 1-cone system As a 2-cone system
- a 3-cone system To the technical Background is referred in this context to DE 10 2008 019 247 A1 and to DE 10 2008 047 483 A1.
- the production of the friction ring according to the invention is carried out by first a metallic base body, which has a toothed surface, is provided.
- the toothing may for example describe a splined shaft profile, a serrated profile or an involute tooth profile.
- a production device is then created in which a cavity is formed between the toothed surface of the base body and the tool.
- a thermoset bulk material mass is filled, which is then compressed in the cavity under pressure and temperature action.
- the tool is removed from the compacted bulk material mass.
- a solid positive connection between the base body and the compacted, the friction lining forming bulk material is already made at this time.
- the base body is hardened in an oven with the mass of bulk material applied thereto.
- a phenol novolak is preferably provided as a thermosetting binder of the friction lining.
- a novolak is a phenolic resin with a formaldehyde-phenol ratio less than 1: 1.
- the pressing of the bulk material mass on the toothed surface of the body is preferably carried out at a temperature of 160-200 ° C, in particular 180 ° C, and a pressure between 10 and 30 N / mm 2 , in particular 20 N / mm 2 .
- the subsequent oven curing is preferably carried out without pressure over a period of not more than one hour at a temperature of 180-220 ° C., in particular 200 ° C.
- the metallic base body of the friction ring can have a toothing in different configurations at different locations.
- a toothing on the outside of the body In the case of a 1-cone system is a toothing on the outside of the body and so that the entire friction ring provided.
- a first ring is made by forming such that it has a toothing on its outer side, said ring serving as mecanicreibreib configuration.
- Another friction ring of the 2 Konussytems has a toothing on its inside and provides a participatreib Formation available.
- an additional conical ring with toothing on the outside is provided.
- the term "toothing" always means that toothing on which the friction lining is formed in a positive-locking manner, whereby a corresponding toothing is created by the manufacturing process in the friction lining.
- its friction lining preferably contains 5-15% of a first type of fiber and 50-70% of carbon particles
- the fibers of the first type may, for example, be carbon fibers or PAN (polyacrylonitrile) fibers
- the use of such fibers in friction materials is known in principle, for example EP 1 394 438 B1 and to EP 0 647 793 B1.
- the friction lining further contains in each case up to 10% tungsten powder and / or copper powder.
- the use of tungsten and copper in a friction lining is known in principle from DE 1 202 076 B, for example.
- aramid fibers may be contained in a concentration of up to 5%.
- a particular advantage of the invention is given by the fact that any preforming of a friction element, such as provided according to EP 1 273 819 B1, is eliminated, so that the friction lining perfectly, without any seams to the non-planar surface of the body adapts, being connected by a positive connection with the body. Also manufacturing steps such as gluing, which represent a potential quality risk, omitted by the production process of the invention. In addition, this method is extremely time-saving feasible.
- Fig. 1 in a schematic representation of a method for producing a friction ring. 1 is a sectional view of a detail of the friction ring produced by the method according to FIG.
- a synchronization device of a transmission circuit comprises a friction ring 1, the production of which is explained below with reference to FIG.
- a friction ring 1 the production of which is explained below with reference to FIG.
- an at least approximately rotationally symmetrical metallic base body 2 is provided, which has a conical surface 3 in the present case, which is to be coated with a friction lining.
- the surface 3 is toothed (not visible in FIG. 1).
- the metallic base body 2 which is a sheet metal part or a sintered part in per se known basic structure, is inserted into a multi-part tool 4.
- the tool 4 is designed such that when the tool 4 is closed between the surface 3 and the Main body 2, a cavity 5 remains free.
- a bulk material mass 6 is filled, which has the following composition:
- Carbon particles for example coke, soot or graphite 50 - 70%
- the bulk material mass 6 located in the cavity 5 is then compressed in the tool 4 under pressure and temperature action.
- the base body 2 After removal of the base body 2 including the bulk material mass 6 thereon, the base body 2 is treated in an oven 7, wherein the final friction lining 8 is formed from the already compacted bulk material mass.
- FIG. 2 The positive connection between the base body 2 and the friction lining 8, which already forms in the tool 4, that is to say in the shaping of the bulk material 6 producing the later friction lining 8, is illustrated in FIG. 2. Clearly visible is a toothing 9 on the surface 3 of the base body 2, in which the friction lining 8 engages. The marked with the reference numeral 10 friction surface of the friction lining 8 is unstructured in the present case. LIST OF REFERENCE NUMBERS
