Electromechanical turning mechanism creating for tracked vehicle as first step to hybrid transmission

Abstract

In the proposed work on the example of tracked multifunctional transporter-tractor MT-LB authors identified critical turning radius depending on the speed and nature of the soil under the criterion of partial and full skid. For obtained turning radius when driving on heavy soils with a coefficient of resistance to rotation =0.8 on each transmittal the transmission power values were obtained, which is necessary to bring to the turning mechanism for the implementation of the rotation with a given radius. Proposed combination Turning Drive, which would allow using lower gears mechanical drive with fixed turning radius and in the upper gears - drive with infinitely variable turning radius. In addition, the proposed technical solution allows you to use the drive mechanism for turning short-term increase in power modes rectilinear motion due to the power stored in batteries, which will significantly improve the mobility characteristics of the machine.
