Abstract
A disc brake for railway vehicles comprising a pad and a disk on which the pad acts is provided. The pad comprises a base plate and a plurality of friction elements fixed to the base plate. The friction elements comprise first friction elements made of a first material and second friction elements made of a second material. The second material has a compressibility modulus (e.g., the pressure needed to compress the material by 1 mm) that is at least 5 MPa less smaller than the compressibility modulus of the first material. There may be more of the first friction elements than the second friction elements.

A disc brake comprising:
- a pad;
- and
- a disk on which the pad acts, the pad comprising a base plate and a plurality of friction elements fixed to the base plate, wherein each of the plurality of friction elements are configured to contact the disk and apply a braking force to the disk, wherein one or more friction elements of the plurality of friction elements being formed as first friction elements made of a first material and one or more different friction elements of the plurality of friction elements being formed as second friction elements made of a second material, the second material having a compressibility modulus that is at least 5 MPa less than the compressibility modulus of the first material, wherein there are more of the first friction elements than the second friction elements.
A disc brake comprising:
- a pad including a base plate and a plurality of friction elements fixed to the base plate, wherein each of the plurality of friction elements are configured to contact a disk and apply a braking force to the disk, wherein one or more friction elements of the plurality of friction elements being formed as first friction elements made of a first material and one or more different friction elements of the plurality of friction elements being formed as second friction elements made of a second material, the second material having a compressibility modulus that is smaller than the first material by at least a designated amount.
A brake comprising:
- a pad including a base plate and a plurality of friction elements coupled to the base plate, wherein the plurality of friction elements are configured to contact a disk and apply a braking force to the disk, each friction element being formed either as a first friction element made of a first material or as a second friction element made of a second material, the friction elements arranged in arch-shaped rows with each arch-shaped row including one or more first friction elements, the second material having a compressibility modulus that is smaller than the first material by at least 5 MPa.
