Description

一种连续油管作业车油电混合动力系统
技术领域
本发明属于石油特车技术领域，更确切地说，本发明涉及一种连续油管作业车混合动力系统。
背景技术
目前石油特车有压裂车、罐车、钻井车、连续油管作业车等，压裂车、钻井车等石油特车因使用次数较少，所以出勤次数较低。连续油管作业车作为布置抽油杆的重要车辆，而且还具有修井、钻井、完井、测井、增产等功能，每口井每年都要进行固定的维修，因此连续油管作业车成为石油特车中使用最频繁的车辆，提高连续油管作业车的经济性可以节省大量费用。但由于连续油管作业车行驶时发动机效率未能达到最佳范围，且制动能量不能回收利用，导致每次出勤时连续油管作业车油耗较大；同时，发动机发生故障后，很难在油田进行维修，液压作业系统无法工作，车辆也无法行驶，整车可靠性较低，通过油电混合动力技术可以综合解决上述问题。
油电混合动力系统有多种构型，目前包括串联、并联和混联三种构型，其中以并联P2构型和混联EVT构型应用最多。连续油管作业车等石油特车都属于工程车辆，目前针对连续油管作业车甚至石油特车的混合动力系统少之又少，这是受行业领域所限，但针对各种工程车辆的油电混合动力系统却屡见不鲜，如专利号为CN107554281A的发明专利公开了一种清洁车混合动力系统及清洁车，该专利采用了单发动机的油电混合动力系统，省却了蓄电池的设计，具有节能、减排功能，但该油电混合动力系统存在不能进行再生制动能量回收、发动机未能工作在高效区、工作模式单一等缺点；专利号为CN 206844182 U的发明专利公开了一种油电混合动力挖掘机，采用发动机和电动机并联的混动模式，用电动机代替了部分配重，结构紧凑，节省了挖掘机底盘面积，但是该油电混合动力系统仅应用于工程作业模式，没有应用到整车行驶模式，未充分开发出混合动力系统的优势。
本发明提出的一种连续油管作业车油电混合动力系统采用了行星排混联式混动构型，具有发动机与电机联合驱动模式、再生制动模式、发动机驱动作业模式、电机驱动作业模式等多种工作模式，有效地提高了连续油管作业车的动力性和经济性，同时配合四挡变速器，减小了传动系统发生故障的可能，提高了整车平顺性和可靠性。
发明内容
本发明所要解决的技术问题是克服连续油管作业车行驶时发动机工作效率较低的问题，在提高整车经济性的同时，提高了整车动力性能，并以系统可靠性和安全性为设计准则，设计了一种连续油管作业车油电混合动力系统。
为解决上述技术问题，本发明是采用如下技术方案实现的：所述的一种连续油管作业车油电混合动力系统，其特征在于，包括发动机1、扭转减振器2、取力器5、分动箱7、液压泵组8、行星排机构、离合器机构、电机装置、四挡变速器18、电池14、后桥27；其中，液压泵组8包括泵1、泵2、泵3、泵4和泵5；离合器机构包括一号离合器4、二号离合器6和三号离合器16；电机装置包括一号电机13和二号电机15。

表2各种工作模式下动力源情况
工作模式 工作动力源
发动机与电机联合驱动 发动机、一号电机、二号电机
电机驱动 一号电机、二号电机
再生制动 一号电机、二号电机
发动机驱动与电池充电 发动机、一号电机
发动机驱动作业 发动机
电机驱动作业 一号电机、二号电机
具体工作原理与工作模式如下：
1、发动机与电机联合驱动模式
参阅图1、图2，当发动机与电机联合驱动时，一号离合器4、二号离合器6和三号离合器16均接合，发动机1的动力通过动力输入轴3传递到行星排机构，行星排行星架12得到动力后，将动力分别传递到行星排太阳轮9和行星排齿圈10，行星排太阳轮9与一号电机13的转子固连，带动一号电机13向电池14充电，此时一号电机13为发电机；同时，电池14为二号电机15放电，此时二号电机15为电动机，二号电机15的转子与动力输出轴17固连，动力输出轴17将行星排齿圈10传递过来的动力与二号电机15产生的动力通过三号离合器16共同传递到四挡变速器18，四挡变速器18再将最终动力传递给后桥27，该模式适用于车辆爬坡、加速等需要短暂大量供能的行驶工况。
在该模式下进行换挡时，需要暂时分离一号离合器4，二号离合器6和三号离合器16均保持接合，二号电机15可以辅助四挡变速器18进行换挡，来减少换挡延时和换挡冲击。
2、电机驱动模式
参阅图1、图3，当只有电机驱动整车行驶时，一号离合器4、二号离合器6均分离，三号离合器16保持接合，发动机1未介入工作，电池14为一号电机13和二号电机15供能，此时，一号电机13和二号电机15均为电动机；一号电机13的转子带动行星排太阳轮9转动，行星排太阳轮9将动力由行星排行星轮11传递到行星排齿圈10，由行星排齿圈10传递过来的动力与二号电机15的转子产生的动力通过三号离合器16共同传递到四挡变速器18，四挡变速器18再将最终动力传递给后桥27，该模式主要用于发动机1发生故障的情况，此时电池作为后备能源，可以短时为电机供能，由双电机驱动车辆到达指定维修点。
在该模式下进行换挡时，需要暂时分离一号离合器16，一号离合器4和二号离合器6均保持分离，此时，二号电机15不能进行辅助换挡。
3、再生制动模式
参阅图1、图4，当车辆进行制动时，一号离合器4、二号离合器6均分离，三号离合器16接合，再生制动动能通过后桥27传递到四挡变速器18，再由四挡变速器18通过三号离合器16带动动力输出轴17转动，动力输出轴17同时带动二号电机15转子和行星排齿圈10转动，行星排齿圈10将动力通过行星排行星轮11和行星排太阳轮9传递到一号电机13的转子，此时，一号电机13和二号电机15均为发电机，两发电机同时为电池14充电。
4、发动机驱动与电池充电模式
参阅图1、图5，当车辆在较好路面行驶时或处于高速行驶状态时，通过一号电机13和二号电机15调节发动机1的工作区域，使其工作在高效区，此时，一号离合器4、二号离合器6和三号离合器16均接合，一号电机13为发电机，二号电机15不工作；发动机1的动力通过动力输入轴3传递到行星排机构，行星排行星架12得到动力后，将动力分别传递到行星排太阳轮9和行星排齿圈10，行星排太阳轮9与一号电机13的转子固连，带动一号电机13向电池14充电，行星排齿圈10带动动力输出轴17转动，动力输出轴17通过三号离合器16将动力传递到四挡变速器18，四挡变速器18再将最终动力传递给后桥27。
在该模式下进行换挡时，需要暂时分离一号离合器4，二号离合器6和三号离合器16均保持接合，二号电机15可以辅助四挡变速器18进行换挡，来减少换挡延时和换挡冲击，此时，二号电机15需要短暂工作。
5、发动机驱动作业模式
参阅图1、图6，当发动机进行驱动作业时，一号离合器4接合，二号离合器6、三号离合器16均分离，发动机1的动力通过动力输入轴3传递到取力器5，与动力输入轴3共线的取力器输出轴断开输出，发动机1的全部动力传递到取力器5的另一输出轴，该输出轴连接分动箱7，分动箱7内部齿轮组将动力分配到液压泵组8中的各个液压泵，此时各个液压泵所在液压回路正常工作，分别完成各自作业；在该模式下，连续油管作业车不行驶，发动机1的全部动力用于工程作业。
6、电机驱动作业模式
参阅图1、图7，当发动机发生故障时，可使用电机驱动作业模式，此模式下，二号离合器6接合，一号离合器4、三号离合器16均分离，一号电机13和二号电机15均为电动机，电池14为一号电机13和二号电机15供能；一号电机13的转子带动行星排太阳轮9转动，二号电机15的转子产生的动力通过行星排齿圈10与行星排太阳轮9传递过来的动力汇合，共同驱动行星排行星架10转动，行星排行星架10通过取力器5将动力传递到分动箱7，分动箱7内部齿轮组将动力分配到液压泵组8中的各个液压泵，此时各个液压泵所在液压回路正常工作，分别完成各自作业。在该模式下，连续油管作业车不行驶，电池14放出的电能全部用于工程作业。
