A full carbon-ceramic axle-mounted brake disc is disclosed, including a disc hub and a plurality of friction discs sleeved on the disc hub and coaxially stacked. The plurality of friction discs and the friction discs and the disc hub are locked and connected integrally through connecting structures. The friction discs are made of a carbon-ceramic composite material and are composed of heat dissipation reinforcing ribs arranged radially on a disc face and a back face, the heat dissipation reinforcing ribs between the stacked friction discs being in contact with each other on a one-to-one basis. Radial heat dissipation channels are formed on two sides of the heat dissipation reinforcing rib, and a connecting groove connecting the radial heat dissipation channels on the two sides is formed between the heat dissipation reinforcing ribs.

An attachment bracket for fastening a heat shield panel of a wheel assembly to a radially inner surface of a wheel, the bracket having an essentially Z-shaped structure comprising an attachment part defining two inner contact surfaces in a first plane each shaped to form, in use, a surface contact with the radially outer surface of the heat shield panel, and a wheel connector part defining an outer contact surface in a second plane arranged to form, in use, a surface contact with the wheel when the heat shield panel is located in position relative to the wheel, where the first and second planes are essentially parallel but spaced apart in the axial direction of the wheel, and a sloping connector part extending from the first plane to the second plane connecting a first end of the attachment part to a first end of the wheel connector part.

A half cap wear clip may comprise: a wear face configured to interface with a torque bar; a first flange disposed on a first side of the wear face and a second flange disposed on a second side of the wear face, the second side opposite the first side; and a deformable feature disposed on a first end of the first flange and the second flange and the wear face, the deformable feature configured to permanently deform a first distance in response to a load on the wear face exceeding a load threshold.

A manufacturing process may comprise: stacking a plurality of friction discs together, each friction disc comprising a lug defining a surface; and depositing a composition to bond to the surface of a first friction disc in the plurality of friction discs to form a wear pad defining a wear surface.

The brake disc arrangement (10) comprises a brake disc (20) which extends annularly about an axially extending central axis and defines an inwardly facing circumference comprising a splined portion for transferring torques between the brake disc (20) and a corresponding hub, when the brake disc arrangement (10) is mounted to the hub. The brake disc arrangement further comprises a spring assembly (30) adapted to be axially connected to the corresponding hub. The inwardly facing circumference of the brake disc (20) comprises one or more cavities (24), each cavity (24) being defined by axially opposing lateral walls (26). The spring assembly (30) is partially contained in said one or more cavities (24), such that a portion of the spring assembly (30) may abut each one out of the axially opposing lateral walls (26).

An aerodynamic noise reduction member 30 includes: a plate-like support portion 32 sandwiched between a plurality of fins 24 and 26 of a brake disk 20 and a rotating member 102 of a railroad vehicle; and a plurality of protruding portions 34 protruding from the support portion 32. Each of the plurality of protruding portions 34 is provided in such a manner that, in a state in which the support portion 32 is sandwiched between the plurality of fins 24 and 26 and the rotating member 102, each of the protruding portions 34 partially occludes between the fastening fin 24 and the anchoring fin 26 adjacent to each other in a circumferential direction of the brake disk 20.

In some examples, a rotor drive key assembly configured to be positioned on a wheel includes an insert and a rotor drive key. The insert is configured to mate with a wheel boss of the wheel and mechanically connect the rotor drive key with the wheel boss. The rotor drive key is configured to mate with the insert such that the insert limits movement of the rotor drive key relative to the wheel boss in at least a radial direction of the wheel. In some examples, the rotor drive key includes a tab having a tab aperture configured to receive a fastener extending in an axial direction of the wheel and engaging the wheel boss.

A brake disk defines an annular shape having a radially inner side and a radially outer side. The brake disk includes: a radially outer braking surface, the braking surface having a maximum operating temperature; a fusible material section radially inward from and connected to the braking surface. The fusible material has a maximum operating temperature, the fusible material section suitable for transmitting torque between the braking surface and a shaft. The maximum operating temperature of the braking surface is higher than the maximum operating temperature of the fusible material section. When the temperature of the fusible material section raises above the maximum operating temperature of the fusible material section, the fusible material section is configured to no longer transmit torque between the braking surface and the shaft.

An eccentric wheel adjustment device includes a hub (1), an adjustment disk (2) and a release structure (3). The hub (1) has an axle portion (10) eccentrically arranged and an inner ring portion (11) formed around the axle portion (10). The adjustment disk (2) has a disk seat (20) for the hub (1) being pivotally disposed thereon and a positioning member (21) for positioning the hub (1) on the disk seat (20). The positioning member (21) has an outer ring portion (210) for aligning the inner ring portion (11) of the hub (1) in the outer ring portion (210). The release structure (3) includes a limiting block (30) and a switch member (31) driving the limiting block (30) to act so as to drive the limiting block (30) to straddle between the hub (1) and the adjustment disk (2) or to move back to the inner ring portion (11).

A brake rotor having first and second panels and first and second sets of mounting flanges. The first set of mounting flanges may extend from the first panel and may be spaced apart from the second panel. The second set of mounting flanges may extend from the second panel and may be spaced apart from the first set of mounting flanges.
