Abstract
BACKGROUND: Specific demands to ensure high mobility and low energy consumption while cornering are given in the process of development transport and special tracked vehicles. Therefore, improvement of values of these parameters is a relevant objective. The mentioned parameters are directly dependent on the chosen type of transmission.
AIM: Derivation of transmission kinematic schemes that provide the best opportunities to ensure the quality of tracked vehicle cornering control with relative simplicity of design.
METHODS: Derivation of transmission kinematic schemes and analytical evaluation of expected transmission properties were based on fundamentals of the theory of ground vehicle dynamics.
RESULTS: The kinematic diagram of a double-flow transmission and rotation mechanism for a transport vehicle with two engines is proposed. The proposed scheme is applicable for tracked chassis, wheeled vehicles using the skid-steering method. The proposed principle of transmission construction can be adapted for a ship with a hybrid powerplant. The modes of operation of the proposed mechanism are presented, its main kinematic and power features are given. An assessment of the required power of the traction electric motor as part of a hybrid powertrain of a transport tracked vehicle weighing 45–50 tons was carried out. Special attention is paid to the problem of the possibility of manufacturing a hybrid powertrain with the proposed transmission based on components, the production of which has been produced in the Russian Federation.
CONCLUSIONS: The proposed transmission scheme may be used for development of new machinery as well as for upgrading of existing vehicles. Main advantages of the proposed scheme are simplicity, compactness, and engine functions duplications. Specific advantages for a transport vehicle with an regenerative steering system are ensuring the mechanical energy recuperation during cornering and braking and ensuring turning the production of a pivot turn.
