FIELD: machine building.
SUBSTANCE: collecting propulsion unit comprises a flexible elastomer-bonded part having a wheel-shaped, generally circular configuration, with a surface bonding with the ground, with the first and second sides corresponding to the first and second sides of the collecting propulsion unit. First and second sides contain, respectively, the first and second circumferentially passing V-shaped grooves located symmetrically and oppositely directed. Collecting propulsion unit is made with the possibility of radial compression of the collecting propulsion unit due to the reversible deformation of the first and second grooves, thereby ensuring the reversible deformation of a detail interlocking with the ground from a round shape into an oblate, when the enlarged portion of the ground-bonding surface is in contact with the moving surface.
EFFECT: technical result is an increased vehicle throughput.
