A rubber belt crawler chain for a vehicle is equipped with chain guiding members which are slidingly guided in one another, are each connected with a cross-piece, and accommodate between one another steel cables of a rubber bearing body surrounding the cross-piece. The cross-piece has two clamping elements forming a receiving device for the steel cables between one another, in which groove-shaped guides for the cables are arranged in one clamping element, and are covered in a web-shaped manner by the other clamping element.

A propulsion unit suspension for propeller driven aircrafts in which a supporting frame is supported at a fire wall; the propulsion unit together with auxiliary aggregates is retained at the supporting frame in several bearings. The bearings of the supporting frame are arranged in two horizontal planes offset in height to one another with an axial distance to one another. The arrangement of the bearings takes place in such a manner that a line of action of the gravity and a further line of action of the propeller thrust extend through an ideal surface delimited by the bearings. In particular, the forward bearing is retained at the supporting frame within the area of a vertical longitudinal plane through the center of gravity as well as above the line of action of the propeller thrust and two rear bearings are located in the supporting framework at approximately the same distance on both sides to the vertical longitudinal plane of the center of gravity and below the line of action of the propeller thrust.
