FIELD: machine building. ^ SUBSTANCE: invention relates to transport machine building, particularly to track vehicles. The proposed track vehicle running gear comprises track idler (1), support rollers (2), spring-loaded balancers (5) and caterpillar chain tensioning mechanism (12). Track idler (1) is mounted, along with the support rollers, on each of bogies (3) arranged in symmetry and mutually balanced by caterpillar chain tensioning mechanism (12) or a tie rod. Both bogies (3) are pivot-jointed to spring-loaded balancers (5) jointed to the ends of torsions (6) fitted in hinges of hubs (7) of two-arm balancer (8) hinged to base (10). The other ends of torsions (6) are linked up by reaction arms (11) with caterpillar chain tensioning mechanism (12) or tie rod. The axes of track idler and balancer hinges are located on caterpillar chain tensioning angle bisectrix. ^ EFFECT: uniform distribution of vehicle weight over support elements axes, smooth running and simpler tensioning device design. ^ 4 cl, 7 dwg |
