Brake disc for a motor vehicle, brake system

A brake disk for a motor vehicle comprising:

• a friction ring;
• a first insert portion having an annular disk shape and located within and arranged coaxially with the friction ring, the first insert portion defining a first plurality of openings;
• and
• a second insert portion having an annular disk shape and located within and arranged coaxially with the friction ring and the first insert portion, the second insert portion spaced apart from the first insert portion and defining a second plurality of openings,
• wherein the friction ring is configured such that the material of the friction ring fills the first plurality of openings and the second plurality of openings,
• wherein the first insert portion is surrounded by the material of the friction ring over the entire periphery of the first insert portion,
• wherein the second insert portion is surrounded by the material of the friction ring over the entire periphery of the second insert portion,
• wherein the first insert portion is a ceramic material,
• wherein the second insert portion is a ceramic material,
• wherein the first plurality of openings includes a plurality of lozenge-like openings, a plurality of circular openings, and a plurality of additional openings shaped uniformly and shaped differently from the plurality of lozenge-like openings and the plurality of circular openings,
• wherein the lozenge-like openings of the plurality of lozenge-like openings are located a first distance from a rotational axis of the first insert portion,
• wherein the circular openings of the plurality of circular openings are located a second distance from the rotational axis of the first insert portion,
• wherein the additional openings of the plurality of additional openings are located a third distance from the rotational axis of the first insert portion,
• wherein the third distance is greater than the first distance and the second distance, and
• wherein the first distance is less than the second distance and the third distance.
