Abstract
In a track laying vehicle (10) a track tensioning apparatus wherein a track engaging idler (20) wheel is mounted to a cross member (82) for adjustment to tension the track by a piston (68) and cylinder (62). The cross member (82) is in turn adjustably (106) mounted to opposing sides (26,27) of the vehicle track frame. Acting in conjunction with the track tensioning apparatus an accumulator (130,146) is provided and is in fluid communication with the piston (68) and cylinder (62). The accumulator (130,146) exerts a backpressure upon the fluid so that the idler (20) may recoil in response to excessive tension or shock upon the track.
