TRANSMISSION FOR HYBRID VEHICLE Russian patent published in 2018 - IPC F16H3/72 B60K6/365 

FIELD: engineering.

SUBSTANCE: invention relates to transmission of hybrid vehicle. Two asymmetric differentials are sequentially included in the transmission. Input of the first differential is connected to the motor shaft, and one of its outputs is connected to the input of second differential. Rotor of the generator is also on the motor shaft. Stator of the generator is connected to the second output of the first differential and is able to rotate about the axis. Stator forms with the rotor an electric machine of double rotation. Second output of the differential is also connected to the controlled clutch, the response part of which is able to stop the second output and the stator of the generator, connecting it to the housing. From the output of the first differential shaft rotation is transmitted to the input of the second, which plays the role of a clutch mechanism in the transmission scheme. One output of the second differential is connected to the driven shaft, and the second output is connected to a power slip clutch which counterpart is connected to the input of this differential connected to the drive shaft. Electric current produced by the generator, when controlling the operation of the first differential mechanism, is applied to the electric motors connected to wheels that are not connected to the driven transmission shaft. These motors are connected via a device consisting of a differential and an associated electromagnetic clutch. Motor shaft is connected to the input of the differential and to the armature of the electromagnetic clutch. One output is connected to the output shaft, and the second one is connected to the clutch inductor. Second output of the differential tends to reverse rotation with respect to the direction of rotation of the motor and the first output of the differential, but the electromagnetic induction force that arises between the clutch armature and the inductor partially blocks the differential and reduces the total ratio, contributing to the acceleration of the driven shaft.

EFFECT: simplification of design is achieved.
