Rubber Track Unit for Vehicle

摘要

A track unit may include one or more bogies arranged between front and rear guide wheels. The bogies are provided with wheel pairs that are rotatably arranged about a longitudinal axis of the bogie itself, and capable of adapting individually to transversal oscillations caused by the terrain. The bogies can furthermore be equipped to adapt to longitudinal oscillations as well, by the longitudinal portion of the bogie being rotatable about a transversal axis. The track unit may also be equipped with a cutter, non-rotatably mounted on one or both outer faces of the rear guide wheel, in a position where said wheel is in direct contact with the track, the cutter configured to cut crop material transported upwards between the rear guide wheel and the track when the track unit moves forward.
