Operational mode is switched:
are convenient for describing, and electric-only mode are defined as pattern one, and series hybrid mode is defined as pattern two, and hybrid mode is defined as pattern three side by side at present.
According to different operating modes and battery 7 charge volumes, automobile switches between three patterns .Switch between three kinds of patterns and be described below.
pattern one → pattern two: when automobile moves in pattern one, driving engine 6, the second motors 2, planet circular system is static.Because of satellite gear has two degree of freedom, synchro 14 sliding hubs pulsation-free easily engage fixedly canine tooth ring 15, so that after ring inner gear 15 fixed, second motor, 2 first start the engines 6 got into pattern two operations then.
pattern two → pattern three: when pattern two switches to pattern three; Synchro 14 breaks away from fixedly canine tooth ring 15; After making the rotating speed of ring inner gear 9 rotating speeds and first motor output shaft 12 reach synchronously through the rotating speed of controlling second motor 2 then; With synchro 14 sliding hub engages axle gear canine tooth rings 16, so just can arrive steadily switching efficiently of pattern three by implementation pattern two again.
pattern one → pattern three: under vehicle control unit controls, automobile switches to pattern two from pattern one earlier, and then switches to pattern three from pattern two.
pattern two → pattern one: only need make synchro 14 sliding hubs break away from fixedly canine tooth ring 15 and place neutral gear position, driving engine 6 is flame-out, and second motor 2 cuts off the power supply and gets final product.
pattern three → pattern one: only need make synchro 14 sliding hubs break away from the shaft gear canine tooth ring 16 on first motor output shaft 12 and place neutral gear position, driving engine 6 is flame-out, and 2 outages of second motor get final product.
pattern three → pattern two: at first make synchro 14 break away from the shaft gear canine tooth ring 16 on first motor output shaft 12 and place neutral gear position; To make the rotating speed of the ring inner gear 9 of planet circular system be zero through controlling second motor, 2 rotating speeds then, makes synchro 14 sliding hubs not have the pulsation-free of impact then and combine fixedly canine tooth ring 15.
various as stated patterns are selected according to vehicle behavior and battery 7 charge volumes, to reach dynamic property, traveling comfort, low energy consumption, the Optimization result of anti-emission carburetor.Because electric-only mode can reach the stroke about 100 kilometers according to designing requirement; The power system of this kind extended-range hybrid vehicle can guarantee pure electric operation under most of situations; Extended-range operation in case of necessity; Thereby realize convenience to the full extent, low energy consumption, zero-emission (or minimum discharging).
The position control of synchro 14: the operational mode of power system is switched by synchro 14 realizations, and the position of synchro 14 i.e. first gear puts 51, and the neutral gear position and second gear put 41 by motor-driven tongue axle 17 controls of single control.Be processed with gearshift groove 18 on the said tongue axle 17; The first retaining portion 5 of said gearshift groove 18 comprise first gear put 51 and said first gear put 51 and said neutral corner portion 21 between the first retaining slope 52, first corner 53 of these first retaining slope, 52 corresponding gearshift grooves 18.The second retaining portion 4 of said gearshift groove 18 comprise second gear put 41 and said second gear put 41 and said neutral corner portion 21 between the second retaining slope 42, second corner 43 of these second retaining slope, 42 corresponding gearshift grooves 18.
this tongue axle 18 has neutral corner portion 21 between the first retaining portion 5 that is in and the second retaining portion 4 so that synchro 14 is in neutral gear position in shift process; Power motor is carried out speed control; Switch synchronously steadily with implementation pattern; Thereby optimize gearshift agility and stationarity, and greatly reduce the wearing and tearing of synchro 14, the life-span of significantly improving synchro 14.
Control process with pattern one → pattern two and pattern two → pattern three below is the extended-range hybrid vehicle power system mode switch control that example is described institute's utility model.
automobile is when pattern one operation; Shift fork contact 20 is in neutral gear position 21; First motor output shaft 12 breaks away from ring inner gear 9, and automobile is by first motor-driven, receive that pattern one → pattern two is switched indication after; Gear shift control driven by motor tongue axle 17 rotates, and about 0.2 second, shift fork contact 20 is in sloping 42 bottoms of second retaining.Get into the second retaining slope 42 then, gear shift control driven by motor tongue axle 17 continues rotation second corner 43, so that synchro 14 sliding hubs engage fixedly canine tooth ring 15, thereby completion pattern one is to the switching of pattern two.
automobile is when pattern two operations, and shift fork contact 20 is in second gear and puts 41, and the sliding hub of synchro 14 engages with planet canine tooth ring 15; After receiving that pattern two → pattern three is switched indication; Shift motor drives tongue axle 17 and rotates, and about 0.2 second, makes shift fork contact 20 be in the bottom on the second retaining slope 42, makes synchro 14 sliding hubs break away from fixedly canine tooth ring 15; This moment, synchro 14 was in neutral, and shift motor drives the 17 continuation rotations of tongue axle simultaneously.Because be provided with neutral corner portion 21; Shift fork contact 20 keeps its axial location, still is in neutral gear position, turns in the time of neutral corner 211 at gearshift tongue axle 17; Through to second motor 2 in addition voltage control make the rotating speed of ring inner gear 9 consistent with first rotating speed of motor; Shift fork contact 20 arrives first gear along the first retaining slope 52 and puts 51 under the control driven by motor then, and the sliding hub of synchro 14 is engaged with shaft gear canine tooth ring 16, thus the switching of completion pattern two to pattern three.A little speed discrepancy in the handoff procedure is synchronous by synchro 14 in first corner 53 on the first retaining slope 52.
other handoff procedure principles are similar with the handoff procedure in the foregoing description.
The power system of the extended-range hybrid vehicle that employing synchro 14 implementation patterns that the utility model proposes switch adopts the design of satellite gear; Its mode switch is realized by electric machine control synchro 14 positions; Simple in structure, possess pure electronic, series hybrid-power; Three kinds of operational modes of parallel connection hybrid power are extended-range hybrid power systems of a kind of Almightiness type.It is low that the utility model has a cost than the hybrid vehicle of present existence and pure electric automobile, the mileage technological merit that waits long and simple in structure.
The power system structure of the extended-range hybrid vehicle that more than the utility model is proposed and principle and embodiment have been carried out detailed technology and have been set forth.Clearly, on the basis of the scope of not leaving the utility model and spirit, can make amendment to existing utility model (comprising technical matters).Technical field under the utility model, a GPRS technical minimum just can carry out various changes in the technological main idea scope of the utility model.
