The adhesion layer includes a metal. The vehicle braking component includes a wear-resistant layer on the thermal barrier layer. The wear-resistance layer includes an iron-aluminum-silicon-zirconium alloy and defines a friction surface of the vehicle braking component.

A force-transmitting assembly includes a metal shaft having at least two longitudinally-extending grooves defined in an outer surface, and a metal hub having at least two longitudinally-extending grooves defined in an inner surface that surrounds the outer surface of the shaft. A plurality of discrete parts is disposed in the at least two longitudinally-extending grooves of the shaft and the hub in an interference-fit manner so as to transmit a torque from the shaft to the hub. Each of the discrete parts is composed of at least 50 mass % of technical ceramic selected from Si.sub.3N.sub.4, SiAlON, Al.sub.2O.sub.3, ZrO.sub.2, or a mixture of two or more of Si.sub.3N.sub.4, SiAlON, Al.sub.2O.sub.3, and ZrO.sub.2.

A brake hub assembly including a brake hub and a brake disk having a first brake surface, a second brake surface spaced axially from the first brake surface, and a plurality of ribs extending between the first and second brake surfaces. Where the brake hub is thermally isolated from the brake hub by various combinations of spacers, torque pins, torque lugs, and the like.

A clutch for a lift fan comprising at least one output shaft lug key positioned in a keyway of at least two output clutch plates and extending axially from one to the other of the two output clutch plates. The output shaft lug key couples the rotation of the output clutch plates to the rotation an output shaft and allows axial movement of the two output clutch plates relative the output shaft lug key. The output shaft has an outer radial surface and an oppositely disposed inner radial surface, and the inner surface of the output shaft lug key extends radially to the seat of the keyway.

A clutch for a lift fan comprises at least one output shaft lug key positioned in a keyway of at least two output clutch plates and extending axially from one to the other of the two output clutch plates. The output shaft lug key couples the rotation of the output clutch plates to the rotation an output shaft and allows axial movement of the two output clutch plates relative the output shaft lug key. The width of an inner surface of the output shaft lug key varies along the axial length as a function of the proximity to a home axial position of each of the output clutch plates when in the disengaged position.

A brake hub assembly couplable to the axle of a vehicle includes a brake hub defining a central axis and having a set of lugs, a brake disk in engagement with the hub and axially slideable over the set of lugs, and a stopping plate formed separately from the hub and fastened to the set of lugs. A first portion of the stopping plate extends between adjacent first and second lugs in the set of lugs. The brake hub assembly also includes an axial preload spring coupled to the hub for clamping the brake disk against the stopping plate. A first portion of the axial preload spring extending between the first and second lugs biases the brake disk toward the first portion of the stopping plate.

An input shaft for the torque-transmitting connection of motor and propeller of a ship drive has input-side and output-side interfaces and a composite hollow shaft made of fiber composite material arranged therebetween. The input shaft has a section which is arranged between the input-side and output-side interfaces, is connected to the composite hollow shaft, and is made of non-flammable material. A ship includes a hull, a bulkhead running transversely to the longitudinal axis of the hull, a motor, a propeller and an input shaft described above. The input shaft of the ship is fed through the bulkhead and has the non-flammable section arranged in the region of the feedthrough through the bulkhead.

Method of assembling a drum brake device includes positioning a portion of a brake shoe (22) support structure (40, 42) near an opening of a brake actuating cylinder (80); manipulating the support structure (40, 42) so that a window (44) of the support structure (40, 42) is received over a portion of a shoe mount (50); moving the support structure (40, 42) relative to the shoe mount (50) so that the portion of the support structure (40, 42) is received into the brake actuating cylinder (80) and the support structure (40, 42) is engaged by the shoe mount (50) in a manner that the shoe mount (50) restricts movement of the brake shoe (22) in two dimensions and allows selective movement in a third dimension; and securing the brake shoe (22) in an installed position by placing the drum (26) over the brake shoe (22) with the braking surface facing the friction lining.

A brake rotor assembly can include a structural part having a receiving surface and at least one friction surface parts having a contact surface. The friction surface part can be fixably attached to the receiving surface of the structural part such that the contact surface faces away from the receiving surface of the structural surface to form at least part of an annular braking surface arranged concentrically around an axis of rotation of the structural part.

A heat dissipation structure for a brake pad is provided for being assembled to a caliper device. The caliper device includes a caliper body, and the caliper body has a receiving space. The heat dissipation structure includes: a main body, integrally extruded from aluminum and cut to have an ultimate appearance, including a plate body and a heat dissipation portion integrally extending from the plate body, the plate body for being disposed on the caliper body and at least partially extending into the receiving space, when the main body is assembled to the caliper body, the heat dissipation portion is exposed outside the caliper body. A brake pad assembly is further provided, including a heat dissipation structure as described above, further including a brake pad, the brake pad disposed on a lateral face of the plate body.
