  • Patent number: 9920807
    Abstract: The invention relates to a friction lining carrier plate (1), which has a metal sheet, to a friction lining, to a friction lining receptacle and to a brake. The metal sheet is formed in such a manner that it has a first and second recess (11, 20) on the friction lining side, wherein the metal sheet has at least a second recess (20) on the friction lining side, wherein the first and second recesses (11, 20) have a differing depth. The first and second recesses on the friction lining side are each formed as an elevation on the side of the actuation means.

  • Patent number: 7728259
    Abstract: A brake lining comprises a lining support plate, an underlayer material and a friction lining. The brake lining is clamped between a pressure plate and a holding fixture, which forms a hole matrix and inside of which electrodes are accommodated. A power supply is connected to the electrodes. The adjacent electrodes have different polarities. A current flow is produced between adjacent electrodes as a result of the different polarities. The field lines extend in the shape of an arch. An arrangement of this type permits the friction lining to be scorched. For hardening, a potential gradient can also be applied between the electrodes and the support plate. The current then flows and the entire friction lining is permeated. This results in a homogenous heating of the friction lining. The invention enables an efficient hardening of the friction lining. It is also possible to conduct a hardening and scorching simultaneously. The invention also enables the friction lining to be pressed during the heat treatment.

  • Publication number: 20060131774
    Abstract: A pressing device having a pressure stamp (1), the sides of which are surrounded by a circumferential wall (2). The circumferential wall (2) is movable counter to the direction of movement of the pressure stamp (2) during and/or after the pressing process, a gap (7) being formed between the pressing material and the circumferential wall (2). The vapors radially escape from the friction lining during and/or after the pressing process and are evacuated via the gap (7), the pressure of the pressure stamp being maintained at least at a reduced level during the entire pressing process.

  • Publication number: 20060131792
    Abstract: A moulded part which is pressed, thermally cured and whose surface is thermally treated in a single processing step, whereby the pressure and the temperature are controlled. As a result, shorter processing times are obtained and the process can be carried out in an energy saving manner, said process being able to be controlled extremely precisely. The moulded part can also be degassed.

  • Publication number: 20060105073
    Abstract: The press is used in the production of friction linings for brake or clutch linings and comprises at least one press station which is provided with a press mould (15, 16, 18) and a pressure ram (19) co-operating therewith. Spindle drives (4, 10) are used for generating relative movements and clamping and closing forces between the mould and the pressure ram, said drives comprising respectively a spindle (5, 12) and an auxiliary spindle nut (7, 13). The relative rotation thereof is driven by an auxiliary electric motor (6, 11), whereby power transmitting rolling bodies embodied in the form of threaded rollers or spherical-shaped elements are respectively arranged between the spindle and the spindle nut. A low-friction area, which can be controlled in a highly accurate path and force dependent manner, is obtained in order to provide a wide distribution of force and ensure dimensional accuracy of the friction linings in addition to an exact adjustment of porosity and compressibility.

  • Patent number: 6808662
    Abstract: In a method for manufacturing friction linings with or without an intermediate layer by compressing the friction material mixtures in a mold of a press during a pressing process comprising at least one pressing cycle, wherein a press control unit controls a plurality of manipulated variables individually or in combination with each other to attain a given lining property (controlled variable) of the friction linings, it is provided that at least one characteristic value representative of the lining property of the friction linings is measured in a first pressing cycle or in a plurality of pressing cycles, and that the manipulated variables are controlled in dependence on the at least one measured characteristic value of the current pressing cycle, the subsequent pressing cycles and/or the subsequent pressing processes.
