HYBRID POWER UNIT OF VEHICLE Russian patent published in 2009 - IPC B60K17/08 F16H37/08 

FIELD: engines and pumps.

SUBSTANCE: invention is related to hybrid power units of vehicles and may be used in city transport, for instance bus. Hybrid power unit of vehicle comprises primary power supply source (1), energy accumulator in the form of, for instance flywheel (18) or accumulator, and also drive comprising planetary disc variator (4), mechanism (12) for forced variation of gear ratio of planetary disc variator (4), which is arranged, for instance in the form of screw-nut gear, system (14) for control of mechanism for variation of gear ratio of planetary disc variator (4), periodically switched unit, for instance demultiplicator (29) comprising one or several gear switched drives, which transmits rotation from planetary disc variator (4) to drive of traction wheels (35) of vehicle. Range of gear ratios variation of periodically switched unit is arranged as lower than range of planetary disc variator variation.

EFFECT: saving of fuel and improved ecological compatibility of vehicle.
