Abstract

A brake device of a vehicle, containing an eddy current disk brake having a rotationally fixed stator and a rotating rotor, wherein the rotor or the stator bears an eddy current path and the stator or the rotor bears a magnetic arrangement, the magnetic field lines of which induce eddy currents in the eddy current path for generating a braking torque upon a relative movement of the rotor with respect to the stator, and a friction disk brake having at least one brake disk and brake pads cooperating with the brake disk for generating a braking friction torque between the brake disk and the brake pads, wherein the rotor of the eddy current disk brake is formed by the brake disk of the friction disk brake.
