ELECTROMECHANICAL TRANSMISSION

The invention relates to the field of mechanical engineering. In the present electromechanical transmission, a drive shaft is connected to a rotor of an electric motor, the stator of which is mounted to a housing and is connected to an input of an asymmetrical planetary differential. One output of said differential is connected to a driven shaft, and a second output is connected to a stator of a generator, said stator freely rotating on the drive shaft. The rotor of said generator is mounted on the drive shaft and rigidly connected thereto. The stator of the generator is connected to a clutch capable of connecting the stator to the housing. When an electrical load is present in the circuit of the generator, the stator is entrained by the rotor, but since the generator stator, which is connected to the differential, strives to rotate in a direction opposite to the direction of rotation of the rotor, the force of induction partially locks the differential and reduces the transmission of rotation through the elements of the differential. The differential and the generator rotate together about an axis. This results in a broader range of revolutions and torque at the output shaft and provides for a smoother change of gear ratio and torque

Invention formula 1. An electromechanical transmission, characterized in that the drive shaft is connected to the rotor of an electric motor, the stator of which is mounted on the housing and is also connected to the input of an asymmetric planetary differential, one output of which is connected to the driven shaft, and the second output is connected to a generator stator that rotates freely on the drive shaft, the rotor of which is also mounted on the drive shaft and is rigidly connected to it, and the generator stator is also connected to a clutch that can connect it to the housing, then, in the presence of an electrical load in the generator circuit, the stator is carried along with the rotor, but since the generator stator, connected to the differential, tends to rotate in the direction opposite to the direction of rotation of the rotor, the induction force partially blocks the differential and reduces the transmission of rotation through the differential elements, reducing the transmission ratio, which consists of the rotation of the differential with the generator around the axis and the gear ratio of the differential gears. 2. An electromechanical transmission according to paragraph one, characterized in that when the load on the driven shaft increases, it slows down, the slip in the generator increases, rotation is transmitted to a greater extent through the differential elements, the gear ratio increases, the speed of rotation of the driven shaft decreases, the torque increases, and when the current increases, the slip decreases, the rotation of the differential elements relative to each other decreases, and the movement on the driven shaft is transmitted to a greater extent through the rotation of the differential around the axis, while the total gear ratio decreases.
