  • Track drive device for an aircraft, a drive arrangement and an aircraft having such a track drive device
    Patent number: 12084185
    Abstract: In order to provide a track drive device for an aircraft that has zero backlash, a large gear reduction, the ability to self-lock, and a better load transfer and reduced wear, the track drive device drives a track member through a drive device that has at least one drive unit that is arranged adjacent to the track member. Each drive unit comprises a plurality of engaging members that are driven by a cam shaft or a cam gear such that the engaging members are sequentially shifted in a wave-like pattern which results in the track member being moved in a linear manner relative to the drive device along a longitudinal direction.
