Abstract
The invention relates to a device for operating a track tension wheel on a tracked vehicle. The device comprises two operating cylinders, a pivoting cylinder () for pivoting a tension wheel arm () that carries a tension wheel, and a tensioning cylinder () for changing the distance between the center () of the tension wheel and the center of rotation () of the tension wheel arm. The tensioning cylinder () is pivotally connected to a pivoting link arm (), which link arm is arranged to be stationary in a first phase of a pivoting upward movement of the tension wheel arm () from a lowered position and to pivot around its connection to the link arm (). In a second phase of the upward pivoting movement, a lug () on the tension wheel arm () is arranged to engage with the link arm () to cause the tensioning cylinder () to be pivoted around the connection of the link arm () to the attachment () during a continued upward pivoting movement of the tension wheel arm ().
