The disclosed drum brake includes a brake disc configured to rotate together with a wheel, an inner brake pad and an outer brake pad arranged on both sides of the brake disc, a pressing member configured to press the inner brake pad toward the brake disc, and a caliper housing provided such that the pressing member moves forward or rearward, wherein the brake disc includes a hub part connected to an axle, a friction part provided in contact with the brake pads and disposed to be spaced a predetermined distance from the hub part in an axial direction, and an accommodation part which is formed between an inner surface of the hub part and an outer surface of the friction part and in which at least a portion of the outer brake pad is accommodated.

In an axle flange, in particular of a commercial vehicle, which is arranged on a wheel axle of a motor vehicle, having at least one flange surface which has a plurality of through holes for connection to a brake carrier, wherein fasteners can be guided through the through holes, the through holes are arranged in such a way that they are adapted firstly to the hole pattern of a brake carrier of a disc brake and secondly to the hole pattern of a brake carrier of a self-supporting drum brake.

A wear resistant friction coating (WRFC) can be applied on a lightweight metallic substrate, by applying a cold gas dynamic spray bond coat containing more iron than any other single element directly onto a surface of the substrate, and thermal spraying the WRFC coating over the bond coat to a thickness of at least 500 m. Corrosion resistance, adhesion, thermal cycling resistance, and wear resistance have been demonstrated.

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 hand-held work implement having a tool has a braking device for the tool that includes a brake band which wraps around a brake drum. The brake band and the brake drum undergo friction as they move relative to one another during braking. At least one of the band or drum comprises an austenitic steel, a duplex steel, super duplex steel, a nickel-base alloy or a cobalt-base alloy and has a base body and a marginal layer. The hardness of the marginal layer is approximately 150% to approximately 600% of the hardness of the base body and the carbide proportion in the marginal layer is less than approximately 0.5% by weight. A process for production of the foregoing includes diffusing carbon and/or nitrogen into a marginal layer at a temperature of less than 500 C.

A brake shoe that is lockable to a rail head of a rail for securing a unit transportable on rails, in particular a high-voltage device, such as a transformer. To maintain the position of the unit securely on a rail in a simple manner, the brake shoe is provided with a frame designed to clasp around at least portions of the rail head and at least one clamping element movably held in the frame. The brake shoe produces self-retaining clamping of the rail between the frame and the at least one clamping element.
