A brake dust particle filter for a brake caliper of a disc brake assembly, wherein the brake caliper comprises a lining inspection opening, closes in a mounted state thereof the lining inspection opening at least partially with precise fit. The brake dust particle filter is provided with a filter medium support that supports a filter medium. A brake caliper provided with the brake dust particle filter in the lining inspection opening is arranged across the brake disc of the disc brake assembly.

A valve has a valve housing with a valve seat and a valve body holder with a fluid-permeable flow opening. A valve body is arranged in the valve body holder and axially displaceable between an open state and a closed state of the valve. The valve body has an envelope surface with a sealing region for fluid-tightly contacting the valve seat in the closed state. It has a base region adjoining the sealing region in longitudinal direction. A cross section contour of the envelope surface increases monotonously from the sealing region to the base region. In the open state, an axial end of the base region contacts the valve body holder. The envelope surface has a weakened region connecting sealing region and base region to each other. The weakened region has a reduced stiffness along the longitudinal direction. The valve body is formed of a thermoplastic polyhalogen olefin.

A brake dust particle filter for a disc brake assembly is provided to catch particles generated during braking. The brake dust particle filter has a ring segment-shaped housing with two axially spaced apart housing side walls and a radially outwardly positioned housing peripheral wall. The housing peripheral wall is arranged between the housing side walls. The housing accommodates the brake disc in the housing interior. A tongue projects inwardly away from the housing peripheral wall in the housing interior. The tongue projects at least in sections with a radial component and has a flat cross section with a base surface facing the housing peripheral wall, an end face projecting into the housing interior, and a side face. The tongue is formed by a filter medium and has no supporting device components separate from the filter medium. The filter medium provides a satisfactory stiffness keeping the tongue structurally stiff.

A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.

Filter arrangement

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.

A unit for the regulation for control of a fluid pressure, having at least one housing section and a switching film connected to the at least one housing section. A chemically inert, non-rubber-like PTFEswitching film switching film is disposed in the valve housing and switches at pressure differences of 1 mbar to 250 mbar for regulating, opening or blocking a flow of a fluid from the inlet to the outlet. The switching film is formed of a fluorine and carbon containing polymer material. The switching film has a plate-shaped flat body with a bending region and has a central closure region surrounded by the bending region. The bending region, when switching the switching film, moves the central closure region relative to a valve seat of the valve housing in an axial direction of the plate-shaped flat body toward or away from the valve seat by a stretch free or low-stretch bending movement.

Brake dust filter

A brake dust particle filter for a disc brake assembly with brake disc and brake caliper has a ring segment-shaped housing accommodating the brake disc in the interior. The housing has first and second axially spaced apart housing sidewalls and a housing peripheral wall extending radially outwardly in circumferential direction and arranged between the first and second housing sidewalls. A first housing part includes the first and/or second housing sidewall such that the first and/or second housing sidewall is positionable axially displaced to the brake disc. A second housing part includes at least the housing peripheral wall. First and second housing parts are connected by a pivot mechanism having a pivot axis extending parallel to an axis of rotation of the brake disc. Due to the pivot mechanism, the housing peripheral wall is pivotable relative to the first housing part while the first and/or second housing sidewall remains stationary.
