Internal-combustion engine's reaction moment supporting and transmission drive shaft's speed adjusting device for hybrid vehicle, has hydraulic device arranged between engine and transmission ratio displaying area of transmission mechanism

摘要

The device (2) has a valve mechanism (8) arranged between a hydraulic machine (5) and a hydraulic pressure accumulator (6) i.e. adiabatic pressure accumulator, where the accumulator is supplied with a hydraulic fluid volume flow during a pumping operation of the hydraulic machine. A hydraulic device (4) is arranged in an installed condition in an output path of a drive train (1) of a hybrid vehicle between an internal-combustion engine (9) and an area of a transmission mechanism (3). The area of the mechanism is provided for display of transmission ratio of the transmission mechanism.
