The filtration device enables the separation and collection of dust and particles produced by the pads of a brake assembly. A first separation unit having an air filtration medium, typically annular, is provided in the housing of the device, in order to define an upstream zone where air is admitted, for example tangentially, and a downstream zone in communication with an outlet of the housing for discharging the purified air. The upstream zone is in communication with a lower stage situated lower down, in which a second separation unit is located in order to separate water from particles that have fallen from the upstream zone. A filtration by the second unit is intended to collect clean water and possibly to discharge this water by gravitational flow. The fallen particles remain trapped inside the device, under the first unit.

Disclosed is a friction assembly for a railway disc brake system for railway rolling stock, the friction assembly including a brake head on the one hand, and on the other hand at least one wear plate made of friction material including a first face which is the friction face, and a second face opposite to the first face, the wear plate being suitable for being integrally secured to the brake head, the friction assembly further including a part able to collect the particles emitted by the wear plate. The part includes a connection able to engage with a fastening element serving to fasten the friction assembly to a brake shoe in such a way that the part is held in a position of being integrally secured to the brake head when the fastening element is fastening the friction assembly to the brake shoe.

A drum brake for a motor vehicle has a pocket for collecting abraded brake particles. The pocket is accessible from above via an opening. After the introduction of a suction device into the opening, the abraded brake particles can be extracted by suction. Pollution of the environment with abraded brake particles is thereby avoided.

A brake dust particle filter for a disc brake assembly of a vehicle has at least one housing structure engaging across a brake disc and/or a brake caliper of the disc brake assembly at least in sections in a mounted state of the brake dust particle filter at the disc brake assembly. The brake dust particle filter is designed to catch particles generated during braking. At least one light source, especially an LED light source, is provided at the brake dust particle filter. A lighting housing part is provided that is to be attached to the housing structure. A vehicle is provided with such a brake dust particle filter provided with a light source.

Disclosed is a system for capturing braking particles from a friction brake system of a machine, which includes a vacuum source, a pneumatic circuit which connects the friction brake system to the vacuum source, and a filter located on the pneumatic circuit and mounted on a support. The capturing system includes a control unit, a control device for the machine, and a clogging detection device for the filter which is capable of sending at least one signal to the control unit when the filter is clogged, the control unit being capable of determining the clogging of the filter, on the basis of this signal, and being capable of determining whether the detection device is inoperative, the control unit being capable of activating the control device to limit the operation of the machine when the filter is clogged or when the detection device is inoperative.

A brake caliper support for a brake caliper of a disc brake assembly with a brake disc has a brake caliper support bracket provided with at least two fastening sections for connecting the brake caliper support to a steering knuckle of a vehicle. The brake caliper support bracket in a mounted state at the vehicle is positioned opposite a brake disc friction surface of the brake disc. A brake caliper support bridge projects away from the brake caliper support bracket in axial direction of the brake disc and circumferentially surrounds the brake disc at least partially in the mounted state. An arc-shaped air guiding element is disposed at the brake caliper support bracket. The air guiding element is positioned axially opposite the brake disc friction surface of the brake disc in the mounted state. The air guiding element is a protrusion or a recess extending axially, respectively.

A brake dust particle filter for a disc brake assembly is provided with a housing that has a first housing side wall, a second housing side wall, and a housing circumferential wall, wherein the housing circumferential wall extends between the first housing side wall and the second housing side wall. A filter insert with a filter medium is arranged in the housing and extends along one of the first and second housing side walls and along the housing circumferential wall. The filter insert has a curved circumferential edge. The housing has a curved receiving groove. The curved circumferential edge engages the curved receiving groove. The filter insert is L-shaped and is configured to at least partially cover a friction surface and a circumferential surface of a brake disc of the disc brake assembly. The curved circumferential edge of the filter insert projects past the filter medium.

A wheel shield includes a central disk having a central wheel hub opening surrounded by annularly spaced stud holes that correspond to a pattern presented by a vehicle. The central disk includes an outwardly open fastening surface such as a channel positioned around an outer diameter of the central disk. The wheel shield includes a radially-compressible ring such as radially extending filaments. The radially-compressible ring has an inner diameter attached in the outwardly open fastening surface of the central disk and sized to engagingly contact an inner diameter of a vehicle wheel rim to restrict movement of brake dust to an exposed outer surface of the vehicle wheel rim while still allowing for the movement of air for cooling.

A brake caliper device for a disc brake assembly with a brake disc has a brake caliper support to be arranged stationarily relative to a vehicle. A brake caliper for holding at least one brake pad is provided, wherein the brake caliper can slide relative to the brake caliper support in an axial direction. A seal device is provided that seals a gap formed between the brake caliper and the brake caliper support. The seal device extends in the axial direction. The seal device has a brush, a sealing lip, and/or a loose sealing material projecting away from the brake caliper support in a direction toward the oppositely positioned brake caliper and/or projecting away from the brake caliper in a direction toward the oppositely positioned brake caliper support.

The disclosure provides a friction disk and a brake including a magnetic yoke iron core, a first movable plate, a friction disk, a first coil, at least one second coil, an armature and an elastic part; the magnetic yoke iron core includes a first mounting space, a second mounting space and at least one third mounting space distributed coaxially; the first movable plate is located in the first mounting space and close to a first shaft end; the friction disk is located in the first mounting space; the first coil is arranged in the second mounting space; the at least one second coil correspondingly is arranged in the at least one third mounting space; the armature is located at the second shaft end; the elastic part has a pre-tightening force that enables the armature to be far away from the magnetic yoke iron core.
