Problems solved by technology

In ventilated brake discs with cooling channels, due to the partitions and undercuts, it is not easy to coat all surfaces in the corresponding cooling channels uniformly and thickly
This may result in some locations being left unpainted individually

Embodiment Construction

[0013] figure 1 An advantageous brake disk 1 is shown in a simplified partial perspective sectional illustration. The brake disk 1 has a circular base disk 2 to which a brake disk drum 3 is fastened, which can alternatively also be formed in one piece with the base disk 2 .

[0014] The base disc 2 has a plurality of integrated cooling channels 4 which extend from the inner circumference of the brake disc 2 to the outer circumference. In this case, the cooling channel 4 runs essentially deviated from the radial extent, in particular curved from the inside to the outside. Furthermore, adjacent cooling channels 4 are configured differently here.

[0015] The base plate 2 here is made of cast iron or aluminum, possibly with a wear-resistant layer, and has a coating 6 on the surface 5 of the cooling channels 4 in order to prevent corrosion, especially in the region of the cooling channels 4 . In particular, all surfaces of the brake disk 1 facing the cooling channels 4 are prov...

Abstract

The invention relates to a method for producing a brake disc (1) for a motor vehicle. A base disc (2), which is made of cast iron or aluminum in particular, is provided and equipped with an anti-corrosion layer (6). The anti-corrosion layer (6) is applied using a wet chemical or galvanic method.

Description

technical field [0001] The invention relates to a method for producing a brake disk for a motor vehicle, wherein a base disk is provided, in particular made of cast iron or aluminum, and is provided with a corrosion-resistant coating on at least one surface. [0002] Furthermore, the invention relates to a brake disc for a motor vehicle, in particular a brake disc produced by the method described above, which has a base disc, in particular of cast iron or aluminum, and on at least one of the base discs Anti-corrosion coating on the surface. Background technique [0003] In conventional brake discs, in particular such brake discs with a cast iron base disc, in order to reduce the tendency to corrosion, the surface of the brake disc is provided with an anti-corrosion coating consisting of a lacquer suitable for this purpose. For example, zinc powder paints have proven to be effective paint materials. The painting is usually carried out by means of spray nozzles in order to m...
