  • 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, 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.

  • Patent number: 5123881
    Abstract: A flexible endless belt for full-track vehicles comprises a belt body made of an elastomeric material, and a longitudinal pull-resistant carrier embedded therein. The soil-engaging contact surface of the belt body is provided with projections while the inner surface flat for contacting the cylindrical mantle surface of rollers of the drive assembly. For the form-locking drive of such a belt and for achieving a vibration and noise reduced drive, the inner surface is provided with bending-resistant transverse stays that are embedded in the belt body and end flush with the edges of the inner surface of the belt. The inner surface is provided with longitudinally extending recesses before and after the transverse stays for engaging teeth provided at the drive roller.

  • Patent number: 4815794
    Abstract: The rotatably mountable track chain roller has two molded axle journal stubs which each engage rotatably in an end cap formed as a radial and axial bearing. Further expecially the track chain roller is provided with lubricant material for its bearings which has a lubricant action on them. An easy and economical manufacture for the track chain roller results when at least one spacer suitable for providing a set value of axial play in the axial direction of the track chain roller is clamped between the track chain roller and one of the end caps without play. The spacer is made of a soft grindable lubricant-resistant material which does not influence the lubricant action and which is grindable against the track chain roller, the axial journal and the end cap. The spacer can be ring shaped and have a plurality of approximately equal width spacing maintaining regions distributed approximately equally circumferentially around the ring and connected by straps of a narrower width.

  • Patent number: 4355988
    Abstract: Track roller for track-laying vehicles such as excavators having a shaft, a roller body rotatably supported thereon, two caps for limiting relative axial movement of shaft and roller body, and end pieces for attaching the track roller to the frame. The shaft has at its center a relatively large diameter, laterally thereof, spaced axially from each other, two relatively wide cylindrical bearing surfaces of larger diameter and, on its sides, ends of reduced diameter with elastic packings at suitable places between the end pieces and the caps and between the caps and the roller body, and an antifriction metal washer arranged between shaft and caps for the feeding of oil to those packings requiring lubrication which is effected from the oil space arranged between the bearing surfaces of the shaft and serves as an oil reservoir.

  • Patent number: 4143898
    Abstract: A bumper for a suspension of a tracklaying vehicle has a first plate formed with a throughgoing hole through which engages one longitudinal end of a bolt. The other longitudinal end of this bolt is screwed into a second plate that is therefore held at a maximum spacing from the first plate. A helical compression spring having in unstressed condition an overall length greater by a predetermined distance than this maximum spacing is braced in compressed condition between the plates. Two telescoping sleeves, one fixed to each of the plates, coaxially surrounds the rod and have free ends extending past each other. Each of these ends has a respective abutment and these two abutments are spaced apart by a distance substantially equal to the difference between the length of the spring in the compressed and uncompressed condition. Thus should this rod break the two abutments will engage each other and prevent the first plate from being violently ejected.
