The brake caliper (14) and the brake caliper housing (22) are designed as separate parts which can be connected to one another, wherein the brake caliper (14) is formed from a bent sheet metal which is reinforced by several welded-on rib structures (38).

Description

[0001] The present invention relates to a brake caliper for a motor vehicle. Furthermore, the invention relates to a motor vehicle having such a brake caliper. State of the art

[0002] Brake units are always used in areas where the movement of systems needs to be reduced in a controlled manner or brought to a standstill. Common types of brake units, for example in vehicles used on the road, include shoe brakes, drum brakes, and disc brakes. During braking, high braking forces act on the components of the brake unit, meaning they must be able to withstand considerable static and dynamic loads. In a disc brake, for example, the brake disc rotating on the wheel shaft is braked by the brake caliper, which is stationary relative to it. The necessary braking force is applied by the brake pads pressing against the brake disc in the bridge area of ​​the brake caliper. Bridge areas in the brake caliper are therefore areas subject to particularly high levels of stress.

[0003] US Pat. No. 6,719,104 B1 describes a brake caliper for a vehicle brake unit and the manufacturing process. The bridge area features local stiffening elements made of a composite material. The stiffening elements are implemented as insert components in various designs by casting, for example, an aluminum alloy in the bridge area.

[0004] The object underlying the invention is to provide a brake caliper for a motor vehicle which is easier to manufacture and has a lower weight.

[0005] The object is achieved by a brake caliper for a motor vehicle having the subject matter of patent claim 1. Preferred embodiments can be found in the dependent claims. Disclosure of the invention

[0006] The invention specifies a brake caliper for a motor vehicle. The brake caliper comprises a brake caliper, which partially encloses a brake disc, and a brake caliper housing in which brake components are arranged. The brake caliper and the brake caliper housing are designed as separate parts that can be connected to one another, and the brake caliper is formed from a bent sheet metal that is reinforced by a plurality of rib structures welded to it.

[0007] By separating the brake caliper housing and the brake caliper, both parts can be manufactured separately, simplifying production. This allows both parts to be customized and adapted independently of each other to specific requirements. The rib structures are also advantageously made of sheet metal, but can also be made of a different material. To absorb the forces generated during braking, the rib structures are attached to the outside of the bent sheet metal and aligned or designed according to the thickness and height. Both parts are welded together at a contact point between the rib structures and the bent sheet metal.

[0008] By forming the brake caliper from a bent sheet metal, manufacturing is significantly simplified compared to a cast component. Furthermore, such a bent sheet metal can be adapted to design changes more easily and cost-effectively, as no expensive casting mold is required. Furthermore, the brake caliper formed from a bent sheet metal is significantly lighter than one made from cast material. Accordingly, the weight of such a brake caliper can be reduced.

[0009] In a preferred embodiment of the invention, the brake caliper is part of an electromechanical brake. An electromechanical brake comprising such a brake caliper is, as previously described, lighter in weight and easier to manufacture.

[0010] In a further preferred embodiment of the invention, the brake caliper is part of a hydraulic brake. A hydraulic brake comprising such a brake caliper is, as previously described, lighter in weight and easier to manufacture.

[0011] Preferably, the brake caliper is connected to the brake caliper housing via a screw connection. A screw connection simplifies the connection to the brake caliper housing. This eliminates the need for complex structures on the brake caliper housing and the brake caliper to connect the two components.

[0012] The invention also provides a motor vehicle having such a brake caliper. Such a motor vehicle has the advantages and properties described above.

[0013] Embodiments of the invention are illustrated in the drawing and explained in more detail in the following description. It shows: Fig. 1 Perspective view of a brake calliper of an electromechanical brake, on which the brake calliper is Fig. 2 may be appropriate, and Fig. 2 Perspective view of a brake caliper according to an embodiment of the invention.

[0014] In Fig. 1 is a brake calliper 10 of an electromechanical brake, on which a brake calliper 14 is arranged Fig. 2. The brake caliper 10 comprises the brake calliper 14, which engages a brake disc 18. Brake pads (not shown) are arranged in the brake calliper 14 and can be applied to the brake disc 18 to brake the motor vehicle. Additionally, the brake caliper 10 comprises a brake caliper housing 22. An electric motor 26 of the electromechanical brake is attached to the brake caliper housing 22. The brake caliper 10 is connected to a brake caliper holder 34 in the region of the brake calliper 14 via guide pins 30.

[0015] Fig. Figure 2 shows a perspective view of a brake calliper 14 according to an embodiment of the invention. This brake calliper 14 can be used instead of the brake calliper shown in Fig. 1 can be used with the brake caliper housing 22. The brake caliper 14 according to the invention is formed from a bent sheet metal, to which several rib structures 38 are welded on the outside. Instead of the two rib structures 38 shown here, additional rib structures 38 can also be welded to the brake caliper 14. These rib structures 38 significantly increase the strength of the brake caliper 14 formed from a bent sheet metal, so that a bent sheet metal material can be used instead of a cast material.

[0016] The Fig.In this exemplary embodiment, the brake caliper 14 shown in Figure 2 has two screw holes 42 through which the brake caliper 14 can be screwed to the brake caliper housing 22 using screws (not shown). This allows the brake caliper 14 to be manufactured separately from the brake caliper housing 22. QUOTES CONTAINED IN THE DESCRIPTION
