Description
技术领域technical field
本发明涉及驱动系统技术领域，具体地，涉及一种双行星齿轮系双电机同轴耦合驱动系统。The invention relates to the technical field of drive systems, in particular to a double planetary gear train double motor coaxial coupling drive system.
背景技术Background technique
汽车动力新能源化、电气化已成为全球发展的重点和热点。The new energy and electrification of automobile power has become the focus and hot spot of global development.
现有电动汽车，一般采用单电机纯电驱动方案。电动机运行点与车辆运行点强耦合，电驱动效率难于优化，使车辆一次充电续航里程缩短。由于单电机的转矩提高会影响系统成本，因此一些车辆采用对电机大速比减速增矩的方案，但这种方案存在电机长时间高速运行带来的可靠性风险。Existing electric vehicles generally adopt a single-motor pure electric drive scheme. The operating point of the motor is strongly coupled with the operating point of the vehicle, making it difficult to optimize the electric drive efficiency, which shortens the cruising range of the vehicle on one charge. Since the torque increase of a single motor will affect the system cost, some vehicles adopt the scheme of decelerating and increasing the torque of the motor with a large speed ratio, but this scheme has the reliability risk caused by the long-term high-speed operation of the motor.
混联式混合动力系统相对于串联混合动力驱动系统和并联混合动力系统，具有极大的性能优势。但现有的混联式混合动力系统，如最具代表性的日本丰田汽车公司的THS(丰田混合动力系统)、THS2(第二代丰田混合动力系统)混合动力系统、通用汽车公司的EP(电动并联)、AHS2(第二代先进混合动力系统)系统，动力合成机构结构复杂、制造成本高。Compared with the series hybrid drive system and the parallel hybrid system, the hybrid hybrid system has great performance advantages. However, the existing hybrid hybrid systems, such as the most representative THS (Toyota Hybrid System) of Toyota Motor Corporation, THS2 (second generation Toyota Hybrid System) hybrid system, General Motors' EP ( electric parallel), AHS2 (second-generation advanced hybrid system) system, the structure of the power synthesis mechanism is complicated, and the manufacturing cost is high.
经对现有技术的文献检索发现一篇公告号为CN201021118Y，专利名称为“混联式混合动力汽车”的中国专利，该专利技术主要包括发动机，该发动机通过一离合器与一电动机机械连接，该电动机再与一驱动桥机械连接，另，所述发动机又与一发电机机械连接，该发动机则通过发电控制器与蓄电池组电气连接，此外，所述电动机还通过一驱动控制器与所述蓄电池组电气连接”，其不足之处是：在纯电驱动模式下，电动机运行点与车辆运行点强耦合，在一定车速下电动机转速固定，其效率难于优化；在混合驱动模式下，在车辆行驶过程中不能实现对发动机的调速优化控制，系统能量效率难于进一步提高；要求电动机转矩大，电动机体积大、重量大，也使系统成本高，否则整车低速动力性不佳，如果采用大减速比的驱动桥解决该问题，则需要更高转速的电机且存在可靠性风险；难于满足不同地域的使用要求，使该系统主要适用于城市车辆。After searching the literature of the prior art, it was found that a Chinese patent with the announcement number CN201021118Y and the patent name "Parallel Hybrid Vehicle" mainly includes an engine, which is mechanically connected to an electric motor through a clutch. The electric motor is mechanically connected to a drive axle, and the engine is mechanically connected to a generator, and the engine is electrically connected to the battery pack through a power generation controller. In addition, the motor is also connected to the battery pack through a drive controller. The shortcoming is: in the pure electric drive mode, the operating point of the motor is strongly coupled with the operating point of the vehicle, and the motor speed is fixed at a certain speed, and its efficiency is difficult to optimize; in the hybrid drive mode, when the vehicle is running In the process, the optimal control of the speed regulation of the engine cannot be realized, and it is difficult to further improve the energy efficiency of the system; the motor torque is required to be large, the volume and weight of the motor are large, and the system cost is also high, otherwise the low-speed dynamic performance of the vehicle is not good. To solve this problem, a drive axle with a reduction ratio requires a higher-speed motor and has reliability risks; it is difficult to meet the requirements of different regions, making the system mainly suitable for urban vehicles.

When the clutch 2 is in the disengaged state, the waste heat stepless speed regulation control of the first motor 3 is realized.
双行星齿轮系同轴耦合多模运行原理：Double planetary gear train coaxial coupling multi-mode operation principle:
单电机纯电动模式如下：控制发动机1处于停机状态，控制离合器2处于分离状态，控制第一同步器71处于空档位置(即，分离状态)、第二同步器72处于在档位置(即，结合状态)后，第一行星齿轮系4的太阳轮43处于自由空转状态，第二电机5通过第二同步器72、第二行星齿轮系6、输出轴15与减速差速器8的输入端之间进行动力传递。The single-motor pure electric mode is as follows: the control engine 1 is in a stopped state, the control clutch 2 is in a disengaged state, the first synchronizer 71 is controlled in a neutral position (that is, a disengaged state), and the second synchronizer 72 is in a gear position (that is, a disengaged state). combined state), the sun gear 43 of the first planetary gear train 4 is in a free idling state, and the second motor 5 passes through the second synchronizer 72, the second planetary gear train 6, the output shaft 15 and the input end of the reduction differential 8 power transmission between them.

In this mode, by controlling the speed of one of the first motor 3 and the second motor 5, stepless speed regulation of the other motor can be realized, thereby achieving the purpose of optimizing system efficiency and avoiding long-term high-speed operation of the motor reliability risk.

In this mode, there is no mechanical transmission between the engine 1 and the wheels 10, so the engine 1 can be controlled to an optimal operating point.
混联混合驱动模式如下：控制发动机1处于运行状态，控制离合器2处于结合状态，控制第一同步器71处于在档位置(即，结合状态)、第二同步器72处于空档位置(即，分离状态)后，发动机1、第一电机3与第一行星齿轮系的齿圈41进行动力传递，第二电机5与第一行星齿轮系的太阳轮43进行动力传递并对发动机1进行无级调速，使发动机1、第一电机3和第二电机5在系统能耗排放最佳点运行。根据第一电机3和第二电机5的运行状态，还可进一步实现单电机并联驱动模式、双电机并联驱动模式、一个电机发电另一电机电动的混联驱动模式等子模式。在此模式下，发动机1与车轮10间可以进行机械传动，但通过对第二电机5实施转速控制，可以在输出轴15的任何转速下，都能将发动机1无级调速到最优运行转速，实现对系统能量效率的优化。The hybrid drive mode is as follows: control the engine 1 to be in the running state, control the clutch 2 to be in the engaged state, control the first synchronizer 71 to be in the gear position (i.e., the engaged state), and the second synchronizer 72 to be in the neutral position (i.e., After the separation state), the engine 1, the first motor 3 and the ring gear 41 of the first planetary gear train carry out power transmission, and the second motor 5 carries out power transmission with the sun gear 43 of the first planetary gear train and performs stepless power transmission to the engine 1. The speed is adjusted so that the engine 1, the first motor 3 and the second motor 5 operate at the optimum point of system energy consumption and emission. According to the operating status of the first motor 3 and the second motor 5, sub-modes such as a single-motor parallel drive mode, a double-motor parallel drive mode, and a hybrid drive mode in which one motor generates electricity and the other motor drives electricity can be further realized. In this mode, mechanical transmission can be carried out between the engine 1 and the wheels 10, but by controlling the speed of the second motor 5, the engine 1 can be steplessly adjusted to optimal operation at any speed of the output shaft 15 speed to optimize the energy efficiency of the system.
第一电机3、第二电机5分别通过高压电缆与电机控制装置12、储能装置11进行电能传递。The first motor 3 and the second motor 5 transmit electric energy to the motor control device 12 and the energy storage device 11 respectively through high-voltage cables.
