スチックに被われている摩擦パッドに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is a friction pad for a disc brake of a rail vehicle, which is characterized by a plate-shaped molded part made of hard ceramic, and a friction material is laminated on the plate surface forming the front surface of the molded part. The plate surface forming the back surface has a plastic cover, the plastic having essentially the same composition as the binder of the friction material attached to the front surface, and the edge surface around the molded part being covered with the friction material. and/or relating to friction pads covered by the plastic of the cover.

な使用温度に達し、事実」ニブレーキ板に当たると直ぐ
に使用ライニング材料の十分な摩擦能力が発揮される。Previously, this type of friction pad was known as a homogeneous molded part made only of friction material, but with this invention,
It has also become possible to improve the braking performance of disc brakes on track vehicles using support plates made of essentially hard plastic. On the other hand, the heat-resistant effect of the plate-shaped ceramic molded part embedded in the friction material makes it possible to use a friction material with greater temperature resistance, and even a small braking force can already cause friction immediately after the start of the braking process. Heating of the material is achieved so that the friction material reaches the required service temperature very quickly, and in fact the full frictional capacity of the lining material used is developed as soon as it hits the brake plate.

度膨張により阻止されるがらである。At the same time, the low thermal conductivity of the hard ceramic protects the braking mechanism from heating. A further advantage compared to conventional friction pads made only of friction materials is that the hard ceramic molded part into which this friction pad is inserted provides a "μ-material" effect.
It is strong against double bending. As a result, even in the case of long braking operations, it is possible to penetrate into the edge region of the friction pad and to apply full coverage to the brake disc. This is because the rigidity of the ceramic molded part embedded in the friction material prevents "hard bending" of the friction pad in the edge area due to the different thermal expansions of the abutment and back area.

が更に改善されるという利点を生じる。The adaptation of the plastic of the cover to the bonding material of the friction lining material used has the advantage that the friction lining on the one hand and the plastic cover on the other hand have approximately the same expansion and pressure behavior. If there are holes in the ceramic molded part due to manufacturing technology, it is also possible to drill holes in the lining material and cover from both sides when attaching them, creating a strong bond in this area. This results in the advantage that the stiffness of the friction lining on the support plate is further improved.

いということである。In one advantageous embodiment of the invention, reinforcements, particularly in the form of a grid, are embedded in the plastic of the cover. This increases the rigidity of the cover, especially when thermosetting plastic deck is used, and the lattice-like structure of the reinforcement allows the reinforcement to be completely embedded in the plastic. According to a further development of the invention, it is advantageous for this reinforcement to extend into the region of at least two opposing end faces. These end faces in particular transmit the reaction forces introduced into the friction pad during braking during subsequent driving to the pincers. According to the invention, the reinforcement is made of wire, glass or plastic fiber fabric. Even though the low thermal conductivity of hard ceramics means that only a small amount of the heating generated during the manufacturing process reaches the back cover, the material used for this purpose is It must still be stable in the temperature range of interest, which means it must not dissolve or decompose.

A friction pad of this kind has on its back side a fixed waist part 2 which is dovetail-shaped in cross section, by means of which the friction pad l is held in the braking mechanism. The friction pad is molded including a fixed waist made entirely of friction material.

The friction force applied to the friction pad parallel to the plane of the rear surface is transmitted from the fixed waist part 2 to the brake holding part and is also absorbed by the ceramic molded part 3 embedded in the friction material described above.

を強めることになる。For reasons of manufacturing technology, it is advantageous to provide in the area of the protrusion a recess 5 which corresponds to the side surface of the ceramic molded part opposite the back surface, so that the ceramic molded part has walls of approximately the same thickness in all areas. It turns out. In the friction pad of FIG. 1, the ceramic body can be provided with holes 6, for example in the form of cylindrical holes, so that the friction material can be pressed simultaneously from both sides or the friction lining and the corresponding plastic mixture can be pressed simultaneously. Holes can be drilled in the material corresponding to the area of the rear surface, so that also in the remaining area other than the edge area a ceramic molded part is inserted between the friction lining and the cover. In particular, the waist-shaped projections 4, which are associated with the associated recesses 5, increase the mechanical rigidity of the molded part.

This lattice-like reinforcement 7 is in particular composed of a fabric made of wire, glass or plastic fibres. The fabric must be of such construction that the plastic material can be threaded through the fabric when the cover is applied, completely embedding the plastic material therein.
