Abstract: A disc brake device for a transportation vehicle having a brake disc, brake pads placed in frictional contact with the brake disc, a brake carrier, and a brake dust collecting device having a brake dust collecting housing situated behind the brake carrier as viewed in a main direction of rotation of the brake disc, wherein the brake dust collecting housing is connected to the brake carrier. Within the brake dust collecting housing, there is arranged a brake dust guiding housing having a U-profile cross section covering the brake disc radially at the outside, wherein the brake dust guiding housing forms a flow channel with an inlet and an outlet for an air stream generated by the rotating brake disc and carrying brake dust to a filter medium of the brake dust collecting housing, and wherein the brake dust guiding housing generates a turbulent air stream in the flow channel.
