Embodiment Construction

[0038] Figure 1 to Figure 5 A brake disc assembly 10 according to a first embodiment of the invention is shown in .

[0039] Such a disc assembly 10 is suitable for disc brake systems, such as those included in railway vehicles. The structure and operation of such a braking system, other than the disc assembly 10, is known and will not be described in further detail here.

[0040] Assembly 10 includes a central drive hub 12 and wear plates.

[0041] The disc includes first and second sides 14,16.

[0042] The faces 14 , 16 are held together axially around the hub 12 .

[0043] The hub 12 is adapted to be connected to an axle 18 for transferring rotation from the axle to the wheel.

[0044] The hub 12 comprises, for example, a substantially cylindrical ring extending around an axis extending along the so-called transverse direction Y, referred to hereinafter as the axis of rotation A.

[0045] Transverse Y is the main direction of the wheel axis.

[0046] The hub 12 also...

Abstract

The invention relates to a brake disc assembly (10) comprising a central drive hub (12) and a wear disc comprising a first face (14) and a second face (16) held axially together around the hub (12). Each face (14, 16) has a respective inner surface (24, 26) and is formed by at least two different sections (32), and each section (32) extends between two radial edges (34, 36). The radial edge (34, 36) of the section (32) of one face (14, 16) does not extend oppositely to the radial edge (34, 36) of the section (32) of the other face (14, 16). Each section (32) of the face is adapted to be fixed to a section of another face via at least one fastening member adapted to hold said face (14, 16).

Description

【Technical field】 [0001] The present invention relates to a brake disc assembly comprising a central drive hub and a wear disc comprising a first face and a second face, the faces held together axially around the hub, each face A respective inner surface having an inner surface facing the other, each face being formed by at least two distinct segments, each segment extending between two radial edges. [0002] The invention also relates to a related railway vehicle. 【Background technique】 [0003] Document FR 2 359 321 describes a disc brake assembly comprising a central drive hub and two wear rings divided into half rings. The half rings are connected by means of screws. [0004] However, as the temperature increases, the components expand. [0005] The expansion generates thermomechanical stresses around the screw as the screw retains the wear ring. [0006] Additionally, deformation of the rings held together at the screws causes the components to fall out of alignment...
