HYBRID VEHICLE POWERTRAIN (VARIANTS)

摘要

The invention relates to the field of vehicle engineering and can be used as a powertrain for hybrid vehicles. A hybrid vehicle powertrain is proposed which comprises at least one independent power source (1) and a flywheel energy accumulator (5) with a mechanical power take off system (9), as well as a multi-range continuously variable transmission with a power split (a supervariator), the input shaft (7) of which is capable of periodic kinematic connection to the power take off system (9) of the flywheel accumulator (5), characterized in that the supervariator has a two-way power split in at least one of its operating ranges and comprises two reversible electric machines (3, 4) which give passage to part of the full power passing through the supervariator and are mechanically connected by a differential drive (12) comprising at least two differential mechanisms (10, 11) to the input shaft (7) and the output shaft (35) of the supervariator, and the independent energy source is in the form of any type of electrical energy accumulator. A hybrid vehicle powertrain is also proposed which comprises at least one independent power source (1) and a flywheel energy accumulator (5) with a mechanical power take off system (9), as well as a multi-range continuously variable transmission with a power split (a supervariator), the input shaft (7) of which is capable of periodic kinematic connection to the power take off system of the flywheel accumulator (1), characterized in that the device comprises a second independent power source (42) in the form of a heat engine, the shaft of which is capable of periodic kinematic connection to the input shaft of the supervariator (7), and the supervariator has a two-way power split in at least one of its operating ranges and comprises two reversible electric machines (3, 4) which give passage to part of the full power passing through the supervariator and are mechanically connected by a differential drive comprising at least two differential mechanisms (10, 11) to the input shaft (7) and the output shaft (35) of the supervariator, and the independent energy source is in the form of any type of electrical energy accumulator.
