Description

Disc brake arrangement for a commercial vehicle and commercial vehicle with such a disc brake arrangement

The invention relates to a disc brake arrangement, in particular for a sliding caliper brake, for a vehicle, in particular a commercial vehicle, having at least one braking device for receiving a brake disc and two brake pads, wherein the brake pads can be brought into friction with the brake disc in order to produce a braking effect on the vehicle , and a brake caliper arrangement, with a brake caliper carrying the brake pads, which surrounds at least a first region of the brake disc, and with a housing surrounding a second region of the brake disc that is not encompassed by the brake caliper, the housing being modular and consisting of a plurality of housing elements . Furthermore, the invention also relates to a commercial vehicle with the disc brake arrangement.

Disc brakes of the aforementioned type are known and are used in commercial vehicles as friction brakes to slow down the movement of the commercial vehicle. Friction brakes work on the principle of friction. Brake pads carried by a carrier, which are arranged on opposite sides of a brake disc, are brought into friction with the brake disc in order to generate a braking effect on the vehicle. The friction between the brake pads and the brake disc creates abrasion on the friction materials of the brake pads and on the brake disc, the brake dust. Brake dust particles are dust particles with a size of, for example, less than 10 pm, so-called fine dust, which is classified as hazardous to health and harmful to the environment due to its small particle size and chemical composition. It is therefore not desirable to release fine dust into the environment. It is therefore of general interest to design disc brakes in such a way that the fine dust produced during the braking process is prevented from being released into the environment as far as possible. A disc brake for a vehicle with a brake housing is known, for example, from document DE 10 2016 108 793 A1. In the disc brake arrangement disclosed there, the brake housing encloses the brake disc on all sides with the exception of the parts of the brake disc encompassed by the brake caliper. The brake housing consists of three housing elements connected to one another and is sealingly attached to the brake caliper.

The previously known housing construction is therefore directly connected to the brake caliper carrying the brake pads. However, further housing elements, for example a housing element for closing a lining shaft of the brake caliper in order to prevent brake dust from escaping into the environment in this area, are not provided.

It should also be taken into account that brake calipers of a friction brake can have different designs. A basic distinction can be made between a brake caliper designed as a fixed caliper (fixed caliper brake) or a brake caliper designed as a sliding caliper or floating caliper (sliding caliper brake or floating caliper brake). With a fixed caliper brake, the brake caliper is firmly attached to a carrier and is therefore immobile. With a floating caliper brake, however, the brake caliper is mounted on the carrier so that it can move laterally. A sliding caliper brake has a more open design than the fixed caliper brake. The comparatively open design and the axial displaceability of the brake caliper of a sliding caliper brake therefore represent an additional challenge in efficiently preventing the brake dust generated during the braking process from being released into the environment with this design.

The invention was therefore based on the object of overcoming the disadvantages listed above as much as possible. In particular, the invention was based on the object of showing a disc brake arrangement that efficiently prevents the release of brake dust into the environment, is easy to maintain and provides a construction that also meets the requirements for the design of a sliding caliper brake. The invention solves the underlying problem in a disc brake arrangement for a commercial vehicle of the aforementioned type with the features of the subject matter of claim 1. In particular, a first housing element and at least a second housing element are each arranged on sides of the brake caliper facing away from one another, the first housing element being arranged in a region of an upper side of the brake caliper facing away from an axis center of the brake disc, and at least the second housing element in a region of a, the underside of the brake caliper facing the axis center of the brake disc is arranged.

According to the invention, a disc brake arrangement, in particular for a sliding caliper brake, is provided for a vehicle, in particular a commercial vehicle. The disc brake arrangement has at least one braking device for receiving a brake disc and two brake pads, the brake pads being able to be brought into friction with the brake disc in order to produce a braking effect on the vehicle, and a brake caliper arrangement, with a brake caliper for displacing the brake pads, of at least one encompasses the first region of the brake disc, and with a housing surrounding a second region of the brake disc that is not encompassed by the brake caliper, the housing being modular and consisting of a plurality of housing elements, with a first housing element and at least one second housing element each on sides facing away from one another of the brake caliper are arranged, wherein the first housing element is arranged in a region of an upper side of the brake caliper facing away from an axis center of the brake disc, and at least the second housing element is arranged in a region of an underside of the brake caliper facing the axis center of the brake disc.

The invention is based on the knowledge that a release of the friction particles resulting from the friction between the brake pads and the brake disc into the environment can be efficiently prevented by enclosing the disc brake arrangement as completely as possible. According to the invention, the housing consists of a plurality of housing elements. The individual housing elements can be connected differently to the brake caliper and/or to the axle parts of the vehicle in order to ensure a largely hermetic seal To provide brake disc to the environment. At the same time, the housing elements can be designed in such a way that axial displaceability of the disc brake arrangement can be ensured, so that the disc brake arrangement also meets the special requirements for the design of a sliding caliper brake. The housing construction provided can offer the possibility of being retrofitted to an already manufactured disc brake.

The brake caliper arrangement according to the invention can in particular be designed as a sliding caliper brake. While in a fixed caliper brake there are two brake pistons, which are used to generate a pressure force on the brake pads that are movably held in the brake caliper, on opposite sides of the brake disc in order to bring the corresponding brake pad into friction with the brake disc, in the design of a sliding caliper brake there is only one of the two brake pads are pressed against the brake disc by a brake piston, while the second brake pad is pressed against the brake disc by the movable brake caliper. In addition, with the design of the sliding caliper brake, a brake fluid advantageously does not have to be guided past a potentially hot brake disc in order to be directed to a brake piston on the opposite side of the brake disc.

The brake caliper and the housing of the brake caliper assembly of the disc brake assembly can together enclose the brake disk of the disc brake assembly. “Enclosing” means “enclosing on all sides” as much as possible, which means that the brake caliper arrangement accommodates or surrounds the brake disc as completely as possible. The brake caliper and the housing of the caliper assembly of the disc brake assembly may encapsulate the brake disc of the disc brake assembly. “Encapsulation” means that the brake caliper arrangement provides a largely hermetically sealed receiving space for the brake disc. By enclosing or encapsulating the brake disc as completely as possible by the brake caliper arrangement, the release of brake dust into the environment can be particularly efficiently reduced and/or prevented, in particular completely prevented. According to a preferred development, the first housing element is mounted on a lining shaft of the brake caliper provided for receiving the brake linings. In particular, the first housing element is mounted on the lining shaft on the top side of the brake caliper facing away from the axis center of the brake disc. In particular, the first housing element can be firmly connected to the brake caliper. In this way, brake dust particles can be efficiently prevented from escaping from a lining shaft on an upper side of the brake caliper. Furthermore, the first housing element mounted on the brake caliper can advantageously “slide along” with the brake caliper when the brake caliper changes its position relative to the brake disc. The first housing element can be mounted on the saddle cheeks of the brake caliper.

In an alternative embodiment, the filter element is arranged on a side of one of the housing elements facing the brake disc. The filter element can be designed to be flat. Furthermore, the filter element can be arranged over an entire inner surface of the interior. In particular, the filter element can be arranged in the fourth housing element, which is designed as a collecting device for collecting brake dust. Alternatively or simultaneously, the filter element is arranged in the area of the ventilation device. It is conceivable that individual filter elements can only be arranged in the air outlet openings. The filter element can be designed to allow air to pass through. The filter element can also be designed to allow water to pass through. At the same time or alternatively, the filter element can be designed to retain brake dust particles of a defined size. Preferably, the filter element can retain particles with a particle size of less than 10 pm. The filter element can thus prevent the brake dust particles from escaping from the interior of the brake caliper assembly and entering the environment. The filter element can be designed to be replaceable. Alternatively or at the same time, the filter element can be designed to be cleanable. In this way, proper function of the filter elements can be permanently ensured. In the case of a no longer functional In order to ensure the function of the filter element, it is sufficient to simply replace the filter element itself. The filter element can be replaceable for this purpose. The filter element can be unnecessary if active suction of the supplied air is provided.
