  • Patent number: 12264717
    Abstract: Stator clips may be disposed in the recesses of aircraft brake stator disks to increase the lug strength of the stator disk. The clips may interface with the splines of a torque plate and may comprise ridges that reduce contact between the torque plate barrel and the clip, while maintaining the overall integrity of the clip structure. Furthermore, reduced contact may enable a reduction in drag, improving brake performance.

  • Patent number: 12246685
    Abstract: A multi-disk brake for a motor vehicle has two multi-disk mechanisms and an actuation device for brake actuation and/or brake release of the multi-disk mechanisms, and an electric drive for translational actuation (spreading) of the actuation device, such as, in particular, the ramp unit. During a spreading operation, the multi-disk mechanisms are pretensioned in a metered manner by the actuation device and produce a desired frictional engagement, and a correspondingly reversed activation of the actuating mechanism enables a correspondingly metered brake release. By means of the electric drive, the action of the multi-disk brake can be metered overall in a particularly precise, sensitive and compensated manner in modern vehicle topology, including all peripheral brake components and systems, including recuperation.
