  • Patent number: 10266218
    Abstract: A tracked chassis for a working machine has a track which includes at least one roller path, preferably two roller paths extending in parallel, on whose running surface at least one plain roller of the tracked chassis is movable during crawler operation. The running surface of at least one roller path of the track and the running surface of at least one roller have a transverse section with an at least sectionally convex contour.

  • Patent number: 9446802
    Abstract: The present invention relates to a track pad for a chain of a chain wheel drive, the track pad having a bearing surface provided with at least one grouser (1, 2), extending in the lateral direction of the bearing surface, wherein at least one flat part (4, 5) is provided next to at least one grouser part (1, 2) in the lateral direction of the bearing surface. Further, the invention comprises a track pad for a chain of a chain wheel drive, the track pad having a bearing surface provided with at least one grouser (32, 33) protruding from a base plate (40), the grouser (32, 33) extending in the lateral direction of the bearing surface, wherein the bearing surface of the base plate has a profile in the lateral direction.

  • Patent number: 5758976
    Abstract: A running wheel is slidably supported on a stationary axle between the axle and the bearing bore with a large bearing play and a small Hertzian stress. The axle has a circumferential section which is defined by its sector with a sector angle of less than 180.degree., wherein its radius of curvature is substantially equal to the radius of curvature of the inner wall of the bearing bore. In accordance with the desired bearing play, the radius of curvature of the remaining circumferential section of the axle is smaller than the radius of curvature of the bearing bore. The direction of the main stress acting upon the running wheel lies in the section of the central plane of the axle sector with the larger radius.
