  • 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.

  • Patent number: 6588553
    Abstract: The present invention relates to a brake pad for rail vehicles, including at least two friction material blocks and at least one holding device. The individual friction material blocks are lamellar in shape and are connected to one another along their longitudinal sides to form a brake pad. The connection is constructed such that the individual friction material blocks may be displaced with respect to one another. The present invention also relates to a rail vehicle brake including at least one brake shoe, a friction material block holding device, a power unit having a carrier body and a connection device connecting the power unit to the at least one brake shoe.

  • Patent number: 6349805
    Abstract: The invention relates to a brake lining mounting, especially for rail vehicles, comprising a lining support which is encompassed at both of its longitudinal ends by guide sections, preferably at least partially by the plates of a lining holder which holds the friction lining. A pin is provided on the lining support and is able to move perpendicularly to the lining support. When the pin is placed under spring tension as the lining holder is pushed up onto the lining support, the pin extends through an opening provided in the lining holder in such a way that the lining holder is stopped on the lining support by this single pin and cannot move in relation to the lining support. At least one spring in the form of a spring clip acts on the pin. The spring clip can be moved into a raised release position against the force of its own tension, carrying the pin with it.

  • Patent number: 6098764
    Abstract: In a brake disk for rail vehicle brake systems, a friction ring is made of a light metal such as aluminum (aluminum alloys), etc. to reduce weight. In order to reduce the weight further by approximately an additional 10%, the hub that supports the friction ring and is connected with the shaft of the rail vehicle is also made of light metal, such as aluminum. It is necessary to keep the temperature of such hubs below 120-140.degree. C. to prevent the shrink or press fit between the hub and shaft from loosening. To prevent such heat transmission, heat insulating layers are inserted between the inner circumference of the friction ring connected with the hub preferably by bolts. In the vicinity of the bolts, these layers can consist of insulating disks, insulating plates, or continuous insulating rings.
