FIELD: transport.
SUBSTANCE: invention relates to transport machine building and is intended to be used in transportation vehicles. Tracklaying vehicle transmission contains two three-link differential mechanisms, two board reversing variable gears and two board range boxes. Output shaft of the first reversing variable gear is connected with the first link of the first three-link differential mechanism. Output shaft of reversing variable right gear is connected with the first link of the second three-link differential mechanism. The second link of the first three-link differential mechanism is connected with input shaft of left board range box and with the third link of the second differential mechanism. The second link of the second differential mechanism is connected with input shaft of right board range box and with the third link of the first differential mechanism. Left and right output shafts of transmission are connected with corresponding output shafts of board range boxes.
EFFECT: higher efficiency of device.
