The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this hybrid electric drive system in parallel comprise power supply 2, motor 3, the final gear 1, the driving engine 1 that are connected with the output shaft 5 of motor 3 that links with power supply 2, the final gear 2 42 that is connected in the belt drive starter motor module 8 (BSG module) on the driving engine 1, the double-clutch automatic gearbox 7 that links to each other with the output shaft 5 of driving engine 1 and is connected with double-clutch automatic gearbox 7.Final gear 1 is meshed with final gear 2 42.In the present embodiment, power supply 2 is a storage battery; Motor 3 has strong power-handling capability, can cooperate with retarder and the individual drive car load travels, and this motor 3 can work in electronic and generating two states, and the while can also be realized forward or reverse under the adjusting of controller; The output shaft 5 of driving engine 1 is two; Final gear 1 and final gear 2 42 can be delivered to the kinetic energy of motor 3 and driving engine 1 generation on the rotation shaft of wheel 6 of drive wheel; Driving engine 1 coupling BSG module makes it possess the start and stop function, realizes the start-stop supervision of driving engine 1 when idling operation automatically, has reduced oil consumption and discharging.
Double-clutch automatic gearbox 7 comprises power-transfer clutch 1 and power-transfer clutch 2 72 and transmission shaft 1, transmission shaft 2 74 and the driven shaft 75 that is connected on 1 two output shafts 5 of driving engine, all is connected by gear transmission structure between transmission shaft 1 and driving engine 1 output shaft 5, between transmission shaft 2 74 and another root driving engine 1 output shaft 5 and between the rear end of driven shaft 75 and transmission shaft 1, transmission shaft 2 74.Driven shaft 75 rear ends are connected with final gear 2 42.
Electric weight more for a long time in storage battery, automobile provides the energy to realize pure driven by power by storage battery, motor 3 converts the electric energy of storage battery to kinetic energy, drives final gear 1 by the output shaft 5 that is connected with motor 3 and rotates, and then kinetic energy is passed to the rotation shaft of wheel 6 of drive wheel.At this moment, the power-transfer clutch 1 in the double-clutch automatic gearbox 7 all is in released state with power-transfer clutch 2 72, and driving engine 1 is in stopped status, and rotation shaft of wheel 6 power of drive wheel are only by the storage battery supply.
When automobile is had relatively high expectations to propulsive effort, when pure driven by power can't satisfy its operating needs, driving engine 1 provided the energy jointly with storage battery, realized combination drive.Specifically, motor 3 converts the electric energy that storage battery provides to kinetic energy, by output shaft 5 drive final geares one 41 rotations of motor 3.Simultaneously, the power-transfer clutch 1 that is connected with automobile gear of living in the double-clutch automatic gearbox 7 engages, and driving engine 1 output shaft 5 drives transmission shaft 1 by gear transmission structure and rotates, at this moment, driven shaft 75 and final gear 2 42 play rotation with one, and power-transfer clutch 2 72 is in released state.Intermeshing final gear 1 provides power for rotation shaft of wheel 6 jointly with final gear 2 42.In this process, when automobile speed during near the gearshift value, because of adjacent gear all is connected with power-transfer clutch 2 72, so, can be by hydraulic pressure by the solenoid control actuating unit of shifting gears, the gear that engagement in advance is about to enter, when automobile speed reaches the gearshift value, only need power-transfer clutch 1 is separated, power-transfer clutch 2 72 engages can finish gearshift, in the shift process, the power of driving engine 1 still constantly is passed to rotation shaft of wheel 6, make automobile realize power shifting, promptly shift process interrupts power, has improved the efficient and the quality of gearshift.
Lower and kinetic energy that driving engine 1 is produced has when more than needed when the electric weight of storage battery, final gear 2 42 passes to rotation shaft of wheel 6 and final gear 1 respectively with kinetic energy, driving engine drives motor 3 and rotates when driving running car, at this moment, motor 3 is converted to electric energy with kinetic energy, for storage battery charges.Similarly, when automobile carries out glancing impact, the power-transfer clutch 1 in the double-clutch automatic gearbox 7 all separates with power-transfer clutch 2 72, and driving engine 1 is shut down, and at this moment, it is battery charge that motor 3 is converted to electric energy with the kinetic energy of automobile.
During reversing automobile, less because of its required propulsive effort, power-transfer clutch 1 separates with power-transfer clutch 2 72; driving engine 1 is shut down, and is driven by storage battery power supply to get final product, and motor 3 controlled devices are regulated and reversed; and remain in certain rotating speed, be used to guarantee the reversing safety of automobile.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
