Analysis of curvilinear motion of tracked vehicles with electromechanical dual-flux turning mechanisms
Keywords:tracked vehicle, dual-flux turning mechanisms, electro–mechanical turning mechanisms, the turning radius
The results of the numerical simulation of the curvilinear motion of tracked vehicles with electromechanical dual–flux mechanisms of the turning are given. The variants were studied of simple modernization of the mechanical step mechanisms of the turning and gears, which were installed on the tractors of the MTLB family produced in large quantities. These tracked vehicles until now display good results on reliability and passability, but they are substantially inferior to contemporary machines in specific power, protection and ergonomic parameters.
The indicated modernization makes it possible to implement, at insignificant cost, a smooth controlled change in the turning radius of the old tracked vehicles, with partial recovery of deceleration energy. In so doing, the transition from controlling the turning with the aid of levers to the steering-wheel control is facilitated.
As a result of conducted studies, it was established that:
– for modernization without a considerable increase in the power of the diesel engine, the most rational appears to be the scheme with two electromotors that work predominantly in the brake mode, retaining the mechanical branch of a regular transmission of a vehicle;
– with an increase in the specific power up to 24 hp/t, the decrease of gear ratios in the branches of the turning mechanism from 2,6 to 2 will make it possible to increase the turnability of the machine by 11–15 % even without introduction of an electric drive to the turning mechanisms.
Obtained results make it possible, at a minimum cost, to draw the characteristics of the old vehicles on the turnability and ease of control closer to the new requirements and standards.
