This article describes original method proposed by authors that provides decreasing of dynamic loading of tractor’s powertrain by means of change of reactive element torsional stiffness. In tracked vehicles one of the most loaded elements is final drive unit which loaded by high dynamic modes. In tractor Chetra 6C-315, final drive is epicyclic where stopped element is ring gear. Authors propose using of strictly resilient (5 degrees in forward-backward direction) mount of ring gear instead of stiffening. Design study of installation between hub and gear ring that connects drum and crown gear, of the resilient metal plates pack was performed. This pack is kind of elastic coupling. Resilient packets of coupling sustain loads and smooth over peak dynamic loads and after elastic deformation of these packets rigid coupling between hub and coupling crown is provided at contact surfaces of skewed stops of hub and crown. To analyse efficiency of proposed method of dynamic loadings decreasing of powertrain elements three-dimensional model of powertrain was created in “Universal Mechanism”. In addition, solid model of caterpillar mover was created in the same software for analysis of influence on powertrain loadings of complex of kinematic and dynamic factors influencing forming of torque on driving sprockets. This article presents results of modelling of loading processes in powertrains elements with elastic coupling and without it during longitudinal motion at various speeds and in turns with various radii. Results show that elements dynamic loading at high loading dynamic modes in case of installed coupling is decreased by 20-30%.
