REPLACEABLE HALF-TRACK TRAIN Russian patent published in 2018 - IPC B62D55/04 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Replaceable half-track train comprises two parallel caterpillar propulsors, each including mounted on the side gear box axle flange driving sprocket, balance truck with support rollers, guide wheels and tension screws with damper, covered by the endless caterpillar rubber-reinforced belt, lever with trunnion, spring-loaded with the elastic element in the form of compression springs, which one end is pivotally connected to the driving axle beam, and to the second end the balance truck is pivotally installed on the trunnion by means of hub. At the trunnion with the lever connection point, perpendicular to the trunnion axis, the crosspiece in the form rectangular cross-section tube is welded in, at which ends at the same distance from the trunnion axis through vertical holes are made, and from above, coaxially with these holes, guide bushings are welded in for the elastic elements in the form of compression springs installation, at that, to the side gearbox base a bracket in the form of staple is bolted, with bent outwards, parallel to the horizon ends, forming pad with holes for the clamping screw, on which lower side, coaxially with these holes, guide bushings are welded in for the elastic elements in the form of compression springs installation.

EFFECT: providing simplified design and improved operational characteristics.
