Abstract
A rail wheel with a wheel body and friction discs connected thereto on both sides by fastening elements, wherein a multi-layer coating is arranged at least between the respective contact surfaces of the friction discs and the contact surfaces of the wheel body with a coating which can be subjected to mechanically and thermally high loading. Also disclosed is a method for producing a rail wheel.
Claims17
A rail wheel having a wheel body and friction disks fitted thereto on both sides by fastening elements, wherein a multi-layer coating is arranged at least between a respective contact surface of the friction disks and a contact surface of the wheel body.
A method for producing a rail wheel having one or more friction disks, comprising:
- providing a friction disk with a contact surface for applying against a contact surface of a wheel body;
- phosphating at least the contact surface of the friction disk to form a phosphate-containing material layer;
- applying a lubricant-containing material layer to the phosphate-containing material layer;
- and
- assembling the rail wheel.
