Detailed description of the invention
The present invention is further illustrated below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of drive system of the hybrid vehicle based on planet gear transmission, it comprises driving engine 1, first motor 2, second motor 9, the mouth of driving engine 1, first motor 2 is in transmission connection by first planet gear mechanism 7, output and second sun and planet gear 8 of first planet gear mechanism 7 are in transmission connection, mouth and second sun and planet gear 8 of the second motor 9 are in transmission connection, and described mouth is connected with wheel 10 by differential mechanism 11.Wherein, first planet gear mechanism 7 is made up of the first sun wheel 12, the first row carrier 13 and the first gear ring 14, and the second sun and planet gear 8 is made up of the second sun wheel 15, second pinion carrier 16 and the second gear ring 17.First gear ring 14 is provided with first clutch 3, for locking first gear ring 14; Mouth and second gear ring 17 of the first row carrier 13 are in transmission connection, the mouth of the second motor 9 and the second sun wheel 15 of the second sun and planet gear 8 are in transmission connection, and be provided with second clutch 4 between the first row carrier 13 of first planet gear mechanism 7 and the second gear ring 17 of the second sun and planet gear 8, for locking second gear ring 17.First motor 2 is connected with stored energy mechanism with the second motor 9, and stored energy mechanism comprises closed-center system 5 and inverter 6.
By the control to driving engine 1, first motor 2, second motor 9, first clutch 3, second clutch 4, the mode of operation of pure motorized motions, series-parallel connection driving and Brake energy recovery can be realized.
(1) pure electronic mode of operation
According to the needs of operating condition, car load can pure electronic mode of operation.Now, second clutch 4 engages, and driving engine 1 and the first motor 2 quit work.Power supply, by inverter 6 and electrical connection, is passed to the second motor 9 by closed-center system 5.The power that second motor 9 exports, is passed to the second pinion carrier 16 by the second sun wheel 15 in second row sun and planet gear 8, is then passed to differential mechanism 11, thus band motor car wheel 10, drive vehicle to advance.
(2) series-parallel connection mode of operation
According to the needs of operating condition, car load can series-parallel connection mode of operation.Now, first clutch 3 engages, and second clutch 4 is separated, the first gear ring 14 locking.
Now the power of driving engine 1 is passed to the first row carrier 13 by the first sun wheel 12, then is passed to the second pinion carrier 16 by the second gear ring 17, is then passed to differential mechanism 11, thus band motor car wheel 10, drive vehicle to advance.
Meanwhile, power supply, by inverter 6 and electrical connection, is passed to the second motor 9 by closed-center system 5.The power that second motor 9 exports, is passed to the second pinion carrier 16 by the second sun wheel 15 in second row sun and planet gear 8, is then passed to differential mechanism 11, thus band motor car wheel 10, drive vehicle to advance.
And the first motor 2 runs needs according to car load, different mode of operations can be in.If the state-of-charge SOC of closed-center system 5 is lower, and the power of driving engine 1 has more than needed, then the first motor 2 can be in generating state.The power supply that first motor 2 provides is charged to closed-center system 5 by inverter 6 and electrical connecting wires, or is directly supplied to the second motor 9 by electrical connecting wires.If the state-of-charge SOC of closed-center system 5 is higher, car load has larger Power output demand, and now, closed-center system 5 provides power supply to the first motor 2 by inverter 6, and the power of the first motor 2 superposes with the power of driving engine 1, jointly drives vehicle.According to car load operating condition needs, the first motor 2 also can be in idle running, off working state.
(4) Brake energy recovery mode of operation
When vehicle be in deceleration, the state such as brake or slide time, according to the needs of operating condition, car load can carry out Brake energy recovery.The power of wheel 10 by differential mechanism 11 be passed to the second motor 9, second motor 9 generate electricity after by inverter 6 and electrical connecting wires, charge to closed-center system 5.By such recovery braking energy, the energy consumption of car load can be saved.
