The channels are provided between the first inner surface of the first braking plate and the second inner surface of the second braking plate. The first blocking part and the second blocking part are provided along the peripheral portion.

A full carbon-ceramic axle-mounted brake disc is disclosed, including a disc hub (2) and a plurality of friction discs (1) sleeved on the disc hub (2) and coaxially stacked. The plurality of friction discs (1) and the friction discs (1) and the disc hub (2) are locked and connected integrally through connecting structures. The friction discs (1) are made of a carbon-ceramic composite material and are composed of heat dissipation reinforcing ribs (11) arranged radially on a disc face (10) and a back face, the heat dissipation reinforcing ribs (11) between the stacked friction discs being in contact with each other on a one-to-one basis. Radial heat dissipation channel (12) are formed on two sides of the heat dissipation reinforcing rib (11), and a connecting groove (13) connecting the radial heat dissipation channels (12) on the two sides is formed between the heat dissipation reinforcing ribs (11). The full carbon-ceramic axle-mounted brake disc has the advantages of a simple structure, excellent heat dissipation effects, reliable connection, high structural strength, convenient maintenance, and a light weight, and reduces the energy consumption and maintenance costs of a transport vehicle while ensuring reliable braking.

A radial mounting torque plate for mounting a disk brake component for heavy-duty vehicles, the torque plate comprising an annular portion and a pair of mounting arms. The annular portion is formed with an opening for receiving an axle of the heavy-duty vehicle. The mounting arms are integrally formed with and extend longitudinally outward in opposite directions from the annular portion and have a T-shaped cross-section.

A hybrid torque tube for a brake assembly may comprise a tube portion having a centerline axis, and a conical back-leg portion extending from the tube portion. A stator spline may be formed on a radially outward surface of the tube portion. A foot may be formed on a radially inward surface of the tube portion. The tube portion is formed using a first manufacturing process and at least one of the conical back-leg, stator spline, or foot is formed using additive manufacturing.

An axle end assembly has a wheel brake arrangement and a wheel hub arrangement. The assembly is designed as a preassembled unit with a hollow shaft element on which the wheel brake arrangement and the wheel hub arrangement are disposed.

An arrangement and method for mounting a brake disc to an axle hub of a vehicle is provided. The arrangement includes wedge-shaped holes at an radially inner region of the brake disc, corresponding wedge-shaped key inserts, a retaining device such as a retaining ring, and mounting devices such as bolts or studs and nuts that pass through the retaining ring and keys to bias the keys against the axle hub. The circumferential sides of the wedge shapes are aligned with radial lines extending from the rotation axis of the axle hub. This arrangement and method provides a simple, robust and easily installed brake disc mounting that minimizes heat transfer between the brake disc and the axle hub and accommodates thermal expansion of the brake disc and the axle hub to minimize thermal expansion-induced stresses to the brake disc.

A braking system for a portal lift assembly includes a shaft operably connected to a vehicle power source and effective to directly or indirectly rotate a wheel of the vehicle upon rotation of the shaft about its axis, a piston positioned along the shaft and effective for applying an axial force along the axis of the shaft, a fluid channel fillable with a non-compressible fluid and effective to apply a hydraulic force to the piston when pressure is applied to fluid in the line, a pressure plate positioned along the shaft and effective for applying an axial force along the axis of the shaft in response to the application of an axial force by the piston. A clutch pack is positioned between the pressure plate and the piston, and includes two sets of clutch plates radially surrounding the shaft. The first set of clutch plates is connected to the shaft in a manner effective to cause those clutch plates to rotate about the axis of the shaft when the shaft rotates. The second set of clutch plates is prevented from rotating about the axis of the shaft. Members of the first set of clutch plates are interspersed between members of the second set of clutch plates, so that when the clutch pack is sufficiently compressed by axial forces applied by the piston and the pressure plate, the first set of clutch plates is forced against the second set of clutch plates so that friction forces between members of the first set of clutch plates and members of the second set of clutch plates slow and may subsequently stop the rotation of the shaft.
