A brake disc assembly includes a central drive hub and a wear disc, which includes first and second faces held together axially about the hub. Each face has a respective inner surface and is formed of at least two distinct segments. Each segment extends between two radial edges. The radial edges of the segments of one face do not extend opposite the radial edges of the segments of the other face. Each segment of the face is adapted to be secured to a segment of the other face via at least one fastening member adapted to hold said faces.

Ventilated disc brake rotors are presented that have significantly increased surface areas for cooling in comparison with currently manufactured disc brake rotors. In an embodiment, the rotors utilize a matric of cooling channels disposed between opposing outside surfaces of friction rings of the rotors. The plurality of cooling channels may be in the form of a three-dimensional lattice or matrix (e.g., repeating or stacked rows of cooling channels). When utilizing such a lattice or matrix, at least a portion of the cooling channels do not directly interface with either friction ring. Rather, at least a portion of the cooling channels interface with (e.g., are surrounded by) other cooling channels. As a result, the total cooling surface area of the rotor may be greatly increased compared to existing rotors.

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.

A hub configured to rotate about an axis of rotation in the circumferential direction, and having a connection surface and a connection opening, the connection opening configured to at least partially receive a connector, the connection surface configured to contact indirectly and/or directly with a contact surface of a brake disc, where the contact surface does not include connection openings.

In one aspect of the present disclosure, a commercial vehicle brake rotor is provided that includes a unitary, one-piece annular body having a central axis of rotation. The annular body includes vents and a braking portion having inboard and outboard braking surfaces. The annular body includes a central mounting flange having through openings to receive studs of a wheel hub. The through openings each have at least a portion thereof extending axially intermediate the inboard and outboard braking surfaces of the annular body. The annular body further includes inboard and outboard air inlets in communication with the vents.

A composite brake disk for a vehicle disk brake, including a brake disk pot which is formed from a first material and is connected to a friction ring made of a different material, wherein the pot shell and a circular-cylindrical collar formed on the friction ring overlap in some regions in the radial direction in a connecting region and are penetrated by a plurality of connecting elements oriented substantially orthogonally with respect to the axis of rotation, wherein the composite brake disk is suitable for transmitting high mechanical and thermal loads in all operating states, while being simple to manufacture, and can also be formed with a particularly thin pot base and, for this purpose, enables the collar to engage radially on the outside around the pot shell in the connecting region.

An axle assembly for a working machine is provided. The axle assembly has an axle housing comprising a central portion housing a gear, wherein the gear is configured to rotate about an axis and is configured to be partially disposed in a lubricant reservoir, and at least one arm portion extending from the central portion, with the arm portion housing at least one driveshaft. The axle assembly further includes a conduit assembly configured to direct lubricant from the central portion to the arm portion, with the conduit assembly including a lubricant catcher having an inlet disposed in an interior volume of the central portion.

A ventilated brake disc includes first and second plates, and a plurality of connecting ribs and protruding ribs. The first and second plates are each shaped as a circular ring, and each have inner and outer surfaces. The inner surfaces of the first and second plates face each other. The first and second plates collectively form a central via and an outer periphery of the ventilated brake disc. Each connecting rib is integrally connected to the inner surfaces of the first and second plates, and elongated in shape, thereby defined with two opposite ends, which are oriented toward the central via and the outer periphery respectively. Each protruding rib protrudes integrally from the inner surface of the first or second plate, and is not connected to the other plate and located between two connecting ribs. The present invention simultaneously attains lightweight and great structural strength and heat dissipating effect.

A mechanical joint configured for providing dissipation of heat generated is provided. The mechanical joint includes a housing containing a motor assembly configured to drive a gear assembly for driving the mechanical joint, the motor assembly configured to be controlled by a control assembly for controlling rotation of a rotor of the motor assembly; wherein a brake disk of the control assembly is configured to increase air flow within the housing. A robot and a robotic system are also disclosed.

A composite brake disk for a vehicle disk brake, including a brake disk pot which is formed from a first material and is connected to a friction ring made of a different material, wherein the pot shell and a circular-cylindrical collar formed on the friction ring overlap in some regions in the radial direction in a connecting region and are penetrated by a plurality of connecting elements oriented substantially orthogonally with respect to the axis of rotation, wherein the composite brake disk is suitable for transmitting high mechanical and thermal loads in all operating states, while being simple to manufacture, and can also be formed with a particularly thin pot base and, for this purpose, enables the collar to engage radially on the outside around the pot shell in the connecting region.
