The invention provides a support assembly for an undercarriage (7) of a vehicle, comprising at least one cushion element (1), at least one holder (2) for connecting at least one cushion element (1) to the undercarriage (7), and at least one fastening means for enabling a releasable connection between the cushion (1) and the holder (2). The cushion elements (1) are releasably carried by the holder (2), and they extend longitudinally along a bottom of the undercarriage (7) and are positionally fitted therealong to mitigate flexing or distortion of at least one track chain carried by the undercarriage (7) during movement of the vehicle.
The present invention relates to a linkage unit (101) for a roller chain link assembly of a caterpillar track, the unit comprising a bushing (102) which has a body and a seat (103) retaining a sealing member (104) at each of the respective axial ends of the body, an outer roller (105) mounted on the bushing (102) for rotation relative to the bushing (102) and means for reducing friction (106) disposed between the internal surface of the outer roller (105) and the outer surface of the bushing (102). The present invention also relates to a roller chain link assembly (110) having the aforementioned linkage unit (101) and a caterpillar track (301) suitable for use in track-type machines employing the roller chain link assembly (110).
