An electromechanical power unit for motor vehicles consisting of at least one drive motor and electric auxiliary motors and gearboxes, characterized by being equipped with at least one main motor (1), at least two electric auxiliary motors (2), an assembly of at least two cycloidal gears (3) and a single or multi-stage mechanical transmission of the main motor (4) driving the main wheel assembly of the cycloidal gear (3). Electric auxiliary motors (2) drive the power input shafts /9/ of the cycloidal gears /3/, and the toothed rim of the main wheel (24) is coupled via a single or multi-stage mechanical transmission (4) with the main motor (1) or main motors, while each power input shaft (9) of the cycloidal gear (3) is coupled via a single or multi-stage mechanical transmission of the auxiliary motor (5) to the electric auxiliary motor or auxiliary motors (2). The power input shafts /9/ of the cycloidal gears (3) have one, two or more cylindrical parts (8a, 8b) with axes eccentrically shifted with respect to the main axis of the power input shaft (9), and on the cylindrical parts (8a, 8b) of the power input shaft (9) through the first needle bearings (15) and (16) the cycloidal discs (10) and (11) are seated. The outer contour (12) of the cycloidal discs (10) and (11) is a curve, such that the heads of the teeth are described by curves with an epicycloid outline, and the feet of the teeth are described by sections of arcs of a circle, or any other arbitrary curve. The main wheel assembly is composed of housing discs (23), main wheel rings (13), toothed rim of the main wheel (24) and rollers (25) with first bushings (26) is a common part for the left and right cycloidal gear (3). The main wheel assembly is equipped on its circumference with rotatably seated first bushings (26) on the rollers (25), one bushing on each roller (25) for one cycloidal disc (10) or (11), with the number of rollers (25) of the main wheel assembly being greater than the outer contour (12) teeth number of the cycloidal disc (10) or (11) by one or two or three.
