  • Patent number: 6742233
    Abstract: The invention is a brake disk and a method of producing the same. The brake disk has at least one friction ring which can be engaged by a brake shoe on at least one side. The friction ring is divided into at least two ring segments having mutually facing end areas configured to be coupled with one another adjacent a junction and separation area. A separation gap is formed between the mutually facing end areas, which mesh with one another. At least one connection device is positioned in the junction and separation area for coupling the ring segments together.

  • Patent number: 6615954
    Abstract: A monitoring system for brake disks, particularly of rail vehicles, having at least two sensors which are arranged in the brake disk or in the proximity of the brake disk and whose sensor signals relate to the temperature of the brake disk. The monitoring system includes at least one transmitter which transmits the sensor signals, and at least one receiver which receives the transmitted sensor signals in a wireless manner. Furthermore, the invention relates to a method of monitoring the temperature of brake disks. The method includes measuring the temperature of at least one brake disk, converting sensor signals to processible values; transmitting the values or the sensor signals to a receiver in one or more of an encoded manner and successively in a timed manner; and processing the received values or sensor signals in one or more of the control unit and the regulating unit.
