On the formation of disturbing torque transmission self-propelled wheeled vehicles
The durability of current and future transmissions of transport vehicles is largely limited to high dynamic loading generated by external and internal perturbations. Uneven loads cause Flexural and torsional vibrations which are the cause of up to 80% failure rate. For the advanced and modernized vehicles designed hydro-mechanical transmission, as it is considered that the introduction of the Converter active filter fluctuations in input and output of the transmission to provide the required level of durability of elements of transmission. However, the results of experimental research experimental designs indicate a high dynamic load transients the beginning of the movement from the place of shifting and locking torque Converter, and steady-state modes of motion of the transport car, which limits the durability of the transmission elements. This determines the necessity of deep research aimed at reducing the dynamic load. The aim of this work was to study the dynamic load generated by external and internal perturbations. The study of the dynamic loading generated by external and internal perturbations, was carried out by theoretical and experimental studies. In the study of variable loading of the powertrain of vehicles they considered the case of steady motion. Theoretically and experimentally found that the magnitude of rolling resistance a self-propelled wheeled vehicle depends on developed its traction, and this influence is particularly noticeable in the disjointed, easily deformable soils. The magnitude of the circumferential forces, with this change in rolling resistance is not linear, as it is accepted in the accepted methods of building traction, and has more complex changes that must be considered when conducting the pulling calculations.
