如图1所示，本发明的混合动力车包括前动力系统和后动力系统。As shown in FIG. 1 , the hybrid vehicle of the present invention includes a front power system and a rear power system.

前动力系统包括发动机1、离合器2、变速箱3、行星齿轮箱4、差速器5、第一电机6和发动机排气后处理器7。The front power system includes an engine 1 , a clutch 2 , a gearbox 3 , a planetary gearbox 4 , a differential 5 , a first electric motor 6 and an engine exhaust after-processor 7 .

变速箱3可采用两轴结构，具有结构简单的优点，而且，一般可采用4档结构(即四组齿轮)，也可采用多档结构。当采用4档结构时，变速箱3的结构较为紧凑。第一电机6可通过齿轮组并入变速箱3的第一齿轮组，从而可通过第一齿轮组提供动力，同时离合器无需倒挡结构，通过第一电机6和第二电机8反转提供倒车动力。The gearbox 3 can adopt a two-shaft structure, which has the advantage of simple structure, and generally can adopt a 4-speed structure (ie, four sets of gears), and can also adopt a multi-speed structure. When the 4-speed structure is adopted, the structure of the gearbox 3 is relatively compact. The first motor 6 can be merged into the first gear set of the gearbox 3 through a gear set, so that power can be provided through the first gear set, and the clutch does not need a reverse gear structure, and reverse rotation is provided by the first motor 6 and the second motor 8 to provide reverse power.

发动机1、离合器2、变速箱3、行星齿轮箱4和差速器5顺次相连。第一电机6与变速箱3相连，且第一电机6和发动机排气后处理器7分别位于变速箱3沿着车身宽度方向的两侧。第一电机6和发动机排气后处理器7分别位于变速箱3沿着车身宽度方向的两侧可有效平衡重量。第一电机6可以根据不同的产品需求进行更换，不受到厚度的限制，可以实现较大的功率输出。The engine 1, the clutch 2, the gearbox 3, the planetary gearbox 4 and the differential 5 are connected in sequence. The first motor 6 is connected to the gearbox 3 , and the first motor 6 and the engine exhaust aftertreatment 7 are respectively located on both sides of the gearbox 3 along the width direction of the vehicle body. The first motor 6 and the engine exhaust post-processor 7 are respectively located on both sides of the gearbox 3 along the width direction of the vehicle body, which can effectively balance the weight. The first motor 6 can be replaced according to different product requirements, is not limited by the thickness, and can achieve larger power output.

行星齿轮箱4可以将变速箱3的动力按照1:1和1:(2～3)的比例对变速箱3输出的扭矩进行放大，输入到差速器5，差速器通过前轴和万向节将扭矩传递到前轮胎上。The planetary gearbox 4 can amplify the power of the gearbox 3 according to the ratio of 1:1 and 1:(2~3) to the output torque of the gearbox 3, and input it to the differential 5. The knuckles transmit torque to the front tires.

后动力系统包括第二电机8、电池包9和油箱10。第二电机8安装在后桥上，电池包9位于第一电机6和第二电机8之间。油箱10安装在第二电机8远离电池包9的一侧。The rear power system includes a second electric motor 8 , a battery pack 9 and a fuel tank 10 . The second motor 8 is mounted on the rear axle, and the battery pack 9 is located between the first motor 6 and the second motor 8 . The fuel tank 10 is installed on the side of the second motor 8 away from the battery pack 9 .

本发明的混合动力车具有多种不同的动力驱动方式，可保证车辆动力需求，提高换挡的平稳性。The hybrid vehicle of the present invention has a variety of different power driving modes, which can ensure the power demand of the vehicle and improve the stability of shifting.

在本发明的混合动力车的一种实施方式中，为了控制整车成本，变速箱3为两轴式变速箱。In an embodiment of the hybrid vehicle of the present invention, in order to control the cost of the entire vehicle, the gearbox 3 is a two-shaft gearbox.

在本发明的混合动力车的一种实施方式中，发动机1布置在前桥的中心轴上。In one embodiment of the hybrid vehicle of the present invention, the engine 1 is arranged on the central axle of the front axle.

在本发明的混合动力车的一种实施方式中，后动力系统还包括消声器11，消声器11与发动机排气后处理器7相连接。通常，消声器11位于整车的尾部。In an embodiment of the hybrid vehicle of the present invention, the rear power system further includes a muffler 11 , and the muffler 11 is connected to the engine exhaust after-processor 7 . Usually, the muffler 11 is located at the rear of the vehicle.

本发明还提供了一种基于本发明的混合动力车的混合动力车动力控制方法，包括如下步骤：The present invention also provides a hybrid vehicle power control method based on the hybrid vehicle of the present invention, comprising the following steps:

离合器断开，第一电机通过变速箱带动行星齿轮箱工作，并通过差速器将动力传递至前轮。The clutch is disconnected, the first motor drives the planetary gearbox to work through the gearbox, and transmits the power to the front wheels through the differential.

当变速箱换挡时，第二电机驱动后轮工作，以补充动力。When the transmission shifts, the second motor drives the rear wheels to supplement the power.

如图2所示(图中箭头为动力传递方向)，离合器2断开，第一电机6通过电机齿轮把动力传递至啮合齿轮，再通过过渡齿轮传递到一档主动齿轮，一档主动齿轮可以将动力通过变速箱3的输入轴，并通过各个档位的齿轮组传递到变速箱输出轴，以将动力输入到行星齿轮箱4。As shown in Figure 2 (the arrow in the figure is the power transmission direction), the clutch 2 is disconnected, the first motor 6 transmits the power to the meshing gear through the motor gear, and then transmits it to the first-speed driving gear through the transition gear. The first-speed driving gear can The power is transmitted through the input shaft of the gearbox 3 and transmitted to the gearbox output shaft through the gear set of each gear, so as to input the power to the planetary gearbox 4 .

在第一电机6直接驱动状态下，第二电机8可以不驱动，也可以根据需要参与驱动。如第二电机8参与驱动，则车辆形成四驱状态，如第二电机8不参与驱动，则车辆呈前驱状态。In the state where the first motor 6 is directly driven, the second motor 8 may not be driven, or may participate in driving as required. If the second motor 8 participates in driving, the vehicle is in a four-wheel drive state; if the second motor 8 does not participate in driving, the vehicle is in a front-wheel drive state.

当变速箱3换挡时，前轮动力会存在中断问题，这时，第二电机8对动力进行补充，可以做到在换挡过程平稳过渡。When the gearbox 3 shifts gears, the front wheel power will be interrupted. At this time, the second motor 8 supplements the power, which can achieve a smooth transition during the shifting process.

在本发明的混合动力车动力控制方法的一种实施方式中，还包括如下步骤：In an embodiment of the hybrid vehicle power control method of the present invention, the method further includes the following steps:
