TRACK DRIVE OF AN AGRICULTURAL PRODUCTION MACHINE

A track drive of an agricultural production machine is disclosed. The track drive includes a driving wheel, a front deflection roller, a rear deflection roller, a continuous caterpillar track around the driving wheel and the deflection rollers, and middle rollers between the front and rear deflection roller. The track drive further includes a track frame and a swing frame. Using the swing frame, the track drive pivots about a first axis of the agricultural production machine, and the track frame pivots about a second axis of the swing frame. The second axis is at a distance from the first axis, and a spring system or damper system is positioned between the track frame and the pivot frame.

ROTARY FEEDTHROUGH

A rotary feedthrough for a compressed air supply system is provided between a stator and a rotor rotating relative to this stator. A compressed air channel disposed in the stator is connected to a compressed air line and leads into an annular chamber formed in the rotor, from which at least one working channel leading to a consumer proceeds. The stator is connected in the region of the rotary feedthrough to a control line. A moment of friction occurring in the region of the rotary feedthrough resulting in premature wear is reduced by providing a switchable non-return valve in the annular chamber. Blocking elements which extend within the annular chamber concentrically to the rotational axis of the rotor are moveable into an open position by an actuating element, which is displaced from the stator in the direction of the blocking elements.
