FIELD: transport engineering; vehicles with self-contained power sources and DC motors. SUBSTANCE: electric transmission has self- contained controlled DC voltage source (traction generator or synchronous generator with rectifier), group of traction motors with reversers and braking resistors, switches to provide change-over of traction motor windings, and diodes. Novelty is use of diodes. EFFECT: simplified realization and optimization of braking. 5 cl, 5 dwg
