需要说明的是，第一电机3为发电电动机，第二电机5为电动机。当发动机4工作、第三离合器8接合且第一离合器6断开时，转子12转动，第一电机3接入负载并处于发电状态，其产生的电能可通过逆变器2储存至蓄电池22中。若此时第二电机5处于工作状态，第一电机3产生的电能可通过逆变器2直接传递给第二电机5，或通过逆变器2储存至蓄电池22中，蓄电池22再通过逆变器2给第二电机5供电。It should be noted that the first motor 3 is a generator motor, and the second motor 5 is a motor. When the engine 4 is working, the third clutch 8 is engaged and the first clutch 6 is disconnected, the rotor 12 rotates, the first motor 3 is connected to the load and is in the power generation state, and the electric energy generated by it can be stored in the battery 22 through the inverter 2 . If the second motor 5 is in the working state at this time, the electric energy generated by the first motor 3 can be directly transmitted to the second motor 5 through the inverter 2, or stored in the storage battery 22 through the inverter 2, and the storage battery 22 is then passed through the inverter. The device 2 supplies power to the second motor 5.
当发动机4工作，且第三离合器8和第一离合器6均接合时，发动机4产生的动力传递至输入轴9，此时第一电机3不工作，即第一电机3未接入负载，第一电机3只产生极小的电能，进而只对发动机4施加极小的负载。When the engine 4 works and the third clutch 8 and the first clutch 6 are both engaged, the power generated by the engine 4 is transmitted to the input shaft 9, and the first motor 3 does not work at this time, that is, the first motor 3 is not connected to the load, and the first motor 3 is not connected to the load. An electric motor 3 generates only a very small amount of electrical energy, and thus only exerts a very small load on the motor 4 .
在本申请的一些实施例中，如图1所示，该车辆混合动力系统还包括差速器14和输出齿轮组21，输出轴10的输出端设置有输出齿轮组21，输出轴10通过输出齿轮组21与差速器14传动连接。该车辆混合动力总成还可包括驱动轴11，差速器14与驱动轴11相连。其中，传动轴11可为车辆的前轴，差速器14能够使其两侧的传动轴11以不同的速度旋转，满足车辆曲线行驶时的需要。In some embodiments of the present application, as shown in FIG. 1 , the vehicle hybrid system further includes a differential 14 and an output gear set 21, the output end of the output shaft 10 is provided with the output gear set 21, and the output shaft 10 passes through the output The gear set 21 is in driving connection with the differential 14 . The vehicle hybrid powertrain may also include a drive shaft 11 , and a differential 14 is connected to the drive shaft 11 . Wherein, the transmission shaft 11 can be the front axle of the vehicle, and the differential 14 can make the transmission shafts 11 on both sides rotate at different speeds to meet the needs of the vehicle when driving in a curve.
具体地，如图1-2所示，一档齿轮组15可包括一档从动轮17和一档主动轮19，一档主动轮19与输入轴9固定连接，一档从动轮17与输出轴10可转动连接。当输入轴9旋转时，一档主动轮19和一档从动轮17旋转，输出轴10可随一档从动轮17旋转。Specifically, as shown in Figures 1-2, the first gear set 15 can include a first gear driven wheel 17 and a first gear driving wheel 19, the first gear driving wheel 19 is fixedly connected to the input shaft 9, and the first gear driven wheel 17 is connected to the output shaft 10 rotatable connections. When the input shaft 9 rotates, the driving wheel 19 of the first gear and the driven wheel 17 of the first gear rotate, and the output shaft 10 can rotate with the driven wheel 17 of the first gear.
在本申请的一些实施例中，如图1-2所示，二档齿轮组16可包括二档从动轮18和二档主动轮20，二档主动轮20与输入轴9固定连接，二档从动轮18与输出轴10可旋转连接。当输入轴9旋转时，二档主动轮20和二档从动轮18旋转，输出轴10可随二档从动轮18旋转。In some embodiments of the present application, as shown in Figures 1-2, the second gear set 16 may include a second gear driven wheel 18 and a second gear driving wheel 20, the second gear driving wheel 20 is fixedly connected to the input shaft 9, and the second gear The driven wheel 18 is rotatably connected to the output shaft 10 . When the input shaft 9 rotates, the second gear driving wheel 20 and the second gear driven wheel 18 rotate, and the output shaft 10 can rotate with the second gear driven wheel 18 .
可以理解的是，为实现变速箱1在一档与二档之间的切换，一档从动轮17 与二档从动轮18之间设置有同步器13，且同步器13与输出轴10固定连接。当同步器13与一档从动轮17接合时，输入轴9通过一档齿轮组15将动力传递书输出轴10，此时同步器13和输出轴10与一档从动轮17具有相同的转速。当同步器13与二档从动轮18接合时，输入轴9通过二档齿轮组16将动力传递至输出轴10，此时同步器13和输出轴10与二档从动轮18具有相同的转速。当同步器13位于一档从动轮17与二档从动轮18之间时，车辆处于空挡状态，输出轴10在惯性作用下旋转。It can be understood that, in order to realize the switching between the first gear and the second gear of the gearbox 1, a synchronizer 13 is arranged between the first gear driven wheel 17 and the second gear driven wheel 18, and the synchronizer 13 is fixedly connected to the output shaft 10 . When the synchronizer 13 was engaged with the first gear driven wheel 17, the input shaft 9 transmitted power to the output shaft 10 through the first gear set 15, and now the synchronizer 13 and the output shaft 10 had the same speed as the first gear driven wheel 17. When the synchronizer 13 is engaged with the second gear driven wheel 18, the input shaft 9 transmits power to the output shaft 10 through the second gear set 16, and the synchronizer 13 and the output shaft 10 have the same rotational speed as the second gear driven wheel 18. When the synchronizer 13 is located between the first gear driven wheel 17 and the second gear driven wheel 18, the vehicle is in a neutral state, and the output shaft 10 rotates under the action of inertia.
需要说明的是，同步器13由车辆的换挡操纵机构控制，可使同步器13与一档从动轮17或二档从动轮18接合，或者位于一档从动轮17与二档从动轮18之间。一档齿轮组15的传动比小于二档齿轮组16，同步器13与一档从动轮17接合时，输出轴10具有较小的转速；同步器13与二档从动轮18接合，输出轴10具有较大的转速。It should be noted that the synchronizer 13 is controlled by the shifting mechanism of the vehicle, so that the synchronizer 13 can be engaged with the first-gear driven wheel 17 or the second-gear driven wheel 18, or be located between the first-gear driven wheel 17 and the second-gear driven wheel 18. between. The gear ratio of the first gear set 15 is smaller than that of the second gear set 16.
