Disk wheel for a motor vehicle and method for producing a disk wheel of this type

A method for producing a disk wheel of a single-track motor vehicle, the method comprising:

• forming the disk wheel integrally from a cast material and, during production of the disk wheel, first, casting a blank of the disk wheel that substantially corresponds to the disk wheel in a casting die having at least two slides, wherein the disk wheel includes:
• a wheel hub, which is arranged concentrically with respect to an axis of rotation of the disk wheel, for mounting the disk wheel on the motor vehicle,
• a wheel rim which is concentric with respect to said wheel hub,
• a first wheel disk, and
• a second wheel disk, wherein
• the first wheel disk and the second wheel disk each extend from the wheel rim in a direction of the wheel hub, are spaced apart from one another on the wheel hub in a transverse direction parallel to the axis of rotation of the disk wheel,
• reinforcing ribs extend directly from the first wheel disk to the second wheel disk and directly connect the first and second wheel disks to each other,
• the first wheel disk and the second wheel disk converge with each other, at the reinforcing ribs, toward the wheel hub,
• the slides are distributed uniformly about the axis of rotation of the disk wheel to be produced, and
• an intermediate space between two slides in each case defines a reinforcing rib of the disk wheel to be produced;
• and
• removing the blank from the casting die, and, during the removal, displacing the slides radially outward, wherein
• an outer layer of the blank is removed at least in a section of the blank corresponding to the wheel disks of the single-track motor vehicle in order to improve surface quality.
