Abstract
Arrangement for controlling a track tension wheel of a tracked vehicle, comprising a guide arm system (), which is swivel-mounted in a part fixed to the vehicle and which carries a wheel axle journal () for rotatably supporting the track tension wheel, in such a way that this can be swiveled by means of a first drive element () between a raised position and a lowered position, and a second drive element () for varying the center-to-center distance between the center axis of the track tension wheel and the swivel axis of the guide arm system in the part fixed to the vehicle. The guide arm system () comprises a first guide arm (), which is swivel-mounted in the part fixed to the vehicle and which via a joint pin () pivotally supports a two-armed lever (), a second guide arm (), which is swivel-mounted in the part fixed to the vehicle and is pivotally connected to a linearly displaceable part () of the first drive element (), and a third guide arm (), which is pivotally connected to the second guide arm () and is pivotally connected to the two-armed lever. One end of the lever () carries the wheel axle journal (), while a linearly displaceable part () of the second drive element () is effectively connected to the two-armed lever () carrying the wheel axle journal ().
