Pure electric hybrid powering pattern handoff procedure:
Due to electric-only mode and hybrid mode handoff procedure more, when superfluous to hybrid mode engine output with electric-only mode 1 gear here, 1-1 gear switches to example explanation.In the time of battery electric quantity abundance, vehicle is when electric-only mode 1 gear, and combined cover B16 and combined cover C4 engage, and combined cover A19 and combined cover D13 throw off, electrical motor I 20 and electrical motor II 21 outputting powers, and driving engine 22 is not worked.Handoff procedure is as follows: combined cover B16 throws off, control electrical motor II 21 rotating speeds and reduce to 0, combined cover A19 is slide joint to the right, and electrical motor II 21 restarts, and drives driving engine 22 to start, combined cover B16 is re-engaged, driving engine 22 outputting powers, drive Vehicle Driving Cycle, and now electrical motor I 20, II 21 stop outside outputting power, but the part power conversion of driving engine 22 outputs is become to electric energy, be battery charging.Power output mode has completed the switching of 1-1 gear while keeping off to hybrid mode engine output surplus by electric-only mode 1.In handoff procedure, there is electrical motor to drive Vehicle Driving Cycle as propulsion source always, power failure-free, dynamic property, ride comfort are good.
From above-mentioned explanation, can find out that the utility model can realize multiple drive modes conversion, the efficient operation that has effectively utilized driving engine and electrical motor is interval, has promoted the dynamic property of vehicle, good economy performance.Shift process and pattern handoff procedure power failure-free, ride comfort is good.No-clutch, relies on gear transmission, and driving efficiency is high.Compact conformation, size is little.
