一种两栖车辆传动系统及其动力传递控制方法
技术领域
本发明属于两栖车辆技术领域，更具体地说，是涉及一种两栖车辆传动系统，本发明还涉及一种两栖车辆传动系统的动力传递控制方法。
背景技术
现有技术中，两栖车辆传动机构是由发动机提供动力，分别通过水上、陆上传动轴系驱动喷水推进器和车轮获取水上推进动力和陆上行驶动力。因此，现有技术中的两栖车辆均采用机械传动方式。这一技术路线过于保守，基于当前国内动总零部件集成技术限制，整车重量目标达成较为困难，同时后期项目扩展新技术的可行性偏低。
发明内容
本发明所要解决的技术问题是：提供一种结构简单，能够方便可靠实现两栖车辆在水上和陆上行驶和切换，既满足传动功能需求，又轻量化、传动效率高、振动噪声低、可拓展性强的两栖车辆传动系统。

所述的两栖车辆传动系统包括陆上动力传递路线和水上动力传递路线。
所述的两栖车辆传动系统的陆上动力传递路线为：发动机→动力电池→前桥和后桥→前驱动电机和后驱动电机→前轮和车轮。
所述的两栖车辆传动系统的水上动力传递路线为：发动机→ISG电机→离合器→水上传动轴→喷水推进器。
所述的前驱动电机连接前减速器，前减速器连接前桥，前桥每端分别安装一个前轮。
所述的后驱动电机连接后减速器，后减速器连接后桥，后桥每端分别安装一个后轮。
本发明还涉及一种结构简单，能够方便可靠实现两栖车辆在水上和陆上行驶和切换，既满足传动功能需求，又轻量化、传动效率高、振动噪声低、可拓展性强的两栖车辆传动系统的动力传递控制方法，所述的两栖车辆传动系统的动力传递控制方法的控制步骤为：
S1.当两栖车辆在陆上行驶时，离合器处于分离状态，动力传递有混动模式和纯电动模式，混动模式传递路径为由发动机带动ISG电机发电，电能传递至动力电池，动力电池输出电流至集成式前、后电驱动桥，最后通过传动轴传递至车轮；S2.电动模式为动力电池输出电流至集成式前、后电驱动桥，最后通过传动轴传递至车轮。
当两栖车辆在水上航行时，控制部件控制离合器吸合，发动机和ISG电机通过离合器、水上传动轴将动力传递至喷水推进器，实现水上航行；当发动机减速时，ISG电机实现能量回收，将回收电能传递至动力电池。
陆上传动采用串联增程式电驱动桥(前桥和后桥)，发动机只用来驱动ISG电机给动力电池(动力电池电量小于某一设定值)发电，不负责陆上机械驱动，整车驱动力通过动力电池提供给电驱动桥(前桥和后桥)，经过减速增扭后通过轮边驱动轴将动力传递至车轮(前轮和后轮)。
水上传动为发动机、ISG电机、离合器和喷水推进器形式，混合动力，纯电不能单独驱动喷水推进器，必须通过发动机、ISG电机、离合器、水上传动轴将动力传递至喷水推进器，前驱动电机和后驱动电机代替变矩器作用，用于加速或者遭遇阻力峰值时，提供额外的功率(来自于动力电池的功率)和驱动力，同时ISG电机也可以用于减速时能量回收。
采用本发明的技术方案，工作原理及有益效果如下所述：
本发明所述的两栖车辆传动系统及其动力传递的控制方法，陆上行驶通过增程式电驱动桥实现，发动机只用来给动力电池充电、不负责陆上机械驱动，整车驱动力通过动力电池提供给电驱动桥，经过减速增扭后通过轮边传动轴将动力传递至车轮，整体布置较为灵活，根据工况需求，可以满足纯电静默行驶，当动力电池电量小于某一设定值，自动启动增程式发动机充电，提高续航里程；由于增程式发动机只提供充电功能，相比传统纯机械传动可以节省水陆分动箱、陆上分动箱以及中间驱动轴重量及布置空间尺寸。根据行驶工况的需求，可以实现两驱和四驱自由切换，并能实现60％爬坡。电桥驱动相比传统纯机械传动，本方案取消水陆分动箱、陆上分动箱以及中间驱动轴，电驱动桥布置位置根据轮边传动轴运动包络，以及整车布置空间自由选择合适的位置，不需要考虑中间传动轴布置角度及空间位置需求，进一步提高布置空间的可行性，具备一定先进性和前瞻性。水上航行时通过发动机和ISG电机经离合器、传动轴至喷水推进器，混合动力驱动，纯电不能单独驱动喷水推进器，必须通过发动机、ISG电机、水上传动轴将动力传递至喷水推进器，由于匹配ISG电机，可以用于能量回收，节省燃油，水上航行时油箱的容积可以节省，达到减重目的。由于此方案加速或者遭遇阻力峰值时，ISG电机可以提供额外的功率和驱动力。本发明所述的两栖车辆传动系统及其动力传递的控制方法，能够方便可靠实现两栖车辆在水上和陆上行驶和切换，既满足传动功能需求，又轻量化、传动效率高、振动噪声低、可拓展性强。

本发明所述的传动系统，两栖车辆在水上航行时，控制部件控制离合器9吸合，发动机8和ISG电机3通过离合器9、水上传动轴10将动力传递至喷水推进器5，实现水上航行；当发动机8减速时，ISG电机3实现能量回收，将回收电能传递至动力电池2。陆上传动采用串联增程式电驱动桥(前桥和后桥)，发动机8只用来驱动ISG电机3给动力电池2(动力电池电量小于某一设定值)发电，不负责陆上机械驱动，整车驱动力通过动力电池2提供给电驱动桥(前桥和后桥)，经过减速增扭后通过轮边驱动轴将动力传递至车轮(前轮和后轮)。
水上传动为发动机8、ISG电机3、离合器9和喷水推进器5形式，混合动力，纯电不能单独驱动喷水推进器5，必须通过发动机8、ISG电机3、离合器9、水上传动轴10将动力传递至喷水推进器9，前驱动电机7和后驱动电机11代替变矩器作用，用于加速或者遭遇阻力峰值时，提供额外的功率(来自于动力电池的功率)和驱动力，同时ISG电机3也可以用于减速时能量回收。
本发明所述的两栖车辆传动系统及其动力传递的控制方法，陆上行驶通过增程式电驱动桥实现，发动机只用来给动力电池充电、不负责陆上机械驱动，整车驱动力通过动力电池提供给电驱动桥，经过减速增扭后通过轮边传动轴将动力传递至车轮，整体布置较为灵活，根据使命需求，可以满足纯电静默行驶，当动力电池电量小于某一设定值，自动启动增程式发动机充电，提高续航里程；由于增程式发动机只提供充电功能，相比传统纯机械传动可以节省水陆分动箱、陆上分动箱以及中间驱动轴重量及布置空间尺寸。根据行驶工况的需求，可以实现两驱和四驱自由切换，并能实现60％爬坡。电桥驱动相比传统纯机械传动，本方案取消水陆分动箱、陆上分动箱以及中间驱动轴，电驱动桥布置位置根据轮边传动轴运动包络，以及整车布置空间自由选择合适的位置，不需要考虑中间传动轴布置角度及空间位置需求，进一步提高布置空间的可行性，具备一定先进性和前瞻性。水上航行时通过发动机和ISG电机经离合器、传动轴至喷水推进器，混合动力驱动，纯电不能单独驱动喷水推进器，必须通过发动机、ISG电机、水上传动轴将动力传递至喷水推进器，由于匹配ISG电机，可以用于能量回收，节省燃油，水上航行时油箱的容积可以节省，达到减重目的。由于此方案加速或者遭遇阻力峰值时，ISG电机可以提供额外的功率和驱动力。本发明所述的两栖车辆传动系统及其动力传递的控制方法，能够方便可靠实现两栖车辆在水上和陆上行驶和切换，既满足传动功能需求，又轻量化、传动效率高、振动噪声低、可拓展性强。
上面结合附图对本发明进行了示例性的描述，显然本发明具体的实现并不受上述方式的限制，只要采用了本发明的方法构思和技术方案进行的各种改进，或未经改进将本发明的构思和技术方案直接应用于其他场合的，均在本发明的保护范围内。
