  • Publication number: 20120061191
    Abstract: A disc brake runs wet by use of cooling fluid, in particular for a road vehicle, and includes stationary stator discs arranged in parallel to and at a distance from one other, and between which in each case a rotatable rotor disc is arranged. During braking, the radially extending stator discs and rotor discs can be pressed against one another, closing an air gap and, after the brake has been released, can be separated from one another, forming the air gap. The brake is designed such that the rotor discs have cooling channels which can be filled with cooling fluid immediately before or at the start of braking.

  • Publication number: 20120037463
    Abstract: A wet-running multi-disc brake includes stator discs, which are arranged in parallel to and at a distance from each other in a rotationally fixed manner, and a rotatable rotor disc positioned in each case between the stator discs. The radially extending stator discs and rotor discs can be pressed against one another during braking by way of a brake application device while overcoming a clearance. The wet-running multi-disc brake is designed such that the brake application device can be mechanically actuated and, via an actuating unit, engages a self-energizing device, which includes a pressure ring that can be pressed towards the rotor discs during braking independently from the rotational direction of the rotor discs.
