    Abstract

    The article, based on the analysis of technical solutions of tyres of various kinds, proposes a fundamentally new constructive performance of high-traffic and survivability tires. The design and operation of the bus is described. The proposed design is theoretically and experimentally justified. Based on the experimental studies of the interaction of the pneumatic tyre with the road surface, the process of traction-clutch characteristics of the airwheeled engine with the ground is simulated. Experimental studies of the pneumatic engine allowed to assess its performance on roads of different condition, depending on the mass and changes in pressure in the event of damage to flexible elements of the wheel. The resulting indicators allow to sufficiently assess not only the survivability of the wheel, its geometric characteristics, but also to describe the physical nature of the interaction of the engine with the road surface, and to confirm the results of theoretical studies. Practical recommendations are given to determine the rational parameters of the tyre of the proposed design. The design of the pneumatic wheel will expand the technological capabilities of the base machine and use it more widely in extreme conditions. The provision of high traffic vehicles proposed in the article pneumatic wheels is conditioned by the need: in the transportation of heavy large cargoes with the exception of separate transportation processes and the subsequent assembly of components.
