A caterpillar propeller of transport vehicles contains supporting tractive 1 and guiding 2 wheels and an elastic caterpillar 3 with a tire tread that envelops the wheels 1, 2. Novelty in the invention is the fact that annular bosses 10, 11 are made on the external surface of wheels 1, 2 between their ends 6, 7, 8, 9, and on internal surface of caterpillar - longitudinal bosses 12. Longitudinal bosses 12 enter into grooves 13, 14 between annular bosses 10, 11 of wheels with possibility of tight pressing by their sides against the sides of these annular bosses at stretching of caterpillar. The bosses on the wheels and on the caterpillar have tapered form. Technical result of use of the invention: increase of frictional force between contact surfaces of tractive wheel and caterpillar and improvement of the fixation of caterpillar on the wheels against transverse shift. |
