分动箱总成与中桥主减速器总成合装，分动箱侧面设置安装孔，设置悬置软件连接分动箱与车架，在传递路径上进行隔振，提升整车NVH性能。
新动力传动系统具备三种动力传动模式，可在6×2模式、6×4模式、6×6模式之间进行切换
图11-12为本发明实施例的双动力系统结构图和原理图，其包含两套动力系统，即第一动力系统和第二动力系统，两组动力系统均设置于本新动力车辆主体内：第一动力系统包括：柴油机A、发电机及控制器、特种动力电池、驱动电机及控制器，减速箱总成一端与驱动电机采用花键连接，另一端与的主减速器总成采用花键连接，前桥轮边减速器总成分别与主减速器由传动轴连接。
第二动力系统包括：第二发动机与AT变速箱合装，分动箱与中桥主减速器总成合装，AT变速箱与分动箱之间由驱动轴连接，中桥主减速器总成贯通轴连接驱动轴，驱动轴连接后桥主减速器总成。中后桥轮边减速器总成分别与主减速器由传动轴连接。
双发动机底盘布置：前轴处，底盘各总成主要布置在驾驶舱和作战舱的车身地板之下，驱动电机—减速箱—前桥主减速器三者通过花键连接。动力舱内，发动机B、自动变速箱、分动箱在动力舱中部位置；发动机A、发电机在发动机B右侧；中桥主减速器、后桥主减速器在发动机B、自动变速箱分总成下方；主副油箱分别在左右中、后轮之间；动力电池在整车左后方；中频电源箱在分动箱上方靠左的位置；其余系统按空间及间隙要求，固定在适当位置。
本发明实施例的新动力特种车辆由于采用双动力系统，达到了机组冗余的目的，在其中一个动力系统失效的情况下，也能保证车辆的整车运行，最大限度的避免了机破事故的发生；且该系统具备三种动力传动模式，可在6×2模式、6×4模式、6×6模式之间进行切换。高速或大负荷行驶采用6×6驱动，良好路面中速行驶可采用6×4驱动，良好路面低速行驶可采用6×2驱动。
实现可在6×2模式、6×4模式、6×6模式之间进行切换的换挡逻辑：分动箱与减速箱档位分别有高、低、空三档。分动箱与减速箱的档位通过整车控制器进行控制。分动箱、减速箱档位的原则为除受相应的开关控制外，当只有一套动力系统驱动车辆时，另一套动力的档位通过相应的空挡强制开关必须强制为空挡。当只有传统动力工作时，分动箱档位受控制开关控制，减速箱强制为空档；当处于混合电驱动或者混合串联模式时，分动箱和减速箱同高同低，受控制开关控制。行车过程中禁止档位的操作，若进行换挡开关操作则分动箱、减速箱档位不响应。
在上述实施例的基础上，本发明实施例的第一动力系统还包括：特种动力电池、中频电源箱及整车控制器。发电机、特种动力电池、中频电源箱通过高压电缆连接。中频电源箱可将发电机发出的交流电，转化输出为中频电，实现为车载大功率设备供电。发动机EMS接受整车控制VCU的信号，通过发动机内部闭环控制实现发动机恒转速，保证发电品质。发电机A可对特种动力电池充电，可实现无发动机工作静默行驶，即特种动力电池直接启动驱动电机，实现整车6X2静默行驶模式，在双发动机发生故障时，可由特种动力电池直接启动驱动电机，实现应急行驶。整车控制器通过CAN线可实现对发动机A、发电机、驱动电机、中频电源箱、特种动力电池的控制。识别整车踏板信号判断驾驶员意图，协调控制双发动机、发电机、驱动电机的转速和转矩，可实现整车动力性和经济性的不同需求。
第二动力系统实现对整车中桥、后桥的驱动，中桥与后桥通过传动轴连接，第一动力系统实现对整车前桥的驱动。前桥与中后桥之间无传动轴刚性连接，使得整车布置空间更加灵活。
单独启动第一动力系统可实现整车6X2驱动模式，单独启动第二动力系统可实现整车6X4驱动模式。为了防止单独启动第一动力系统时，整车对中后桥反拖以及单独启动第二动力系统时，整车对前桥反拖造成零部件损坏，系统在减速箱和分动箱上设置了空挡，保证两套系统单独驱动时，整车可正常行驶。同时启动第一动力系统和第二动力系统时，可实现整车6X6驱动模式。
本发明的双动力系统特种车辆，可保证在单个动力系统失效的情况下，整车可继续行驶。双发动机合理匹配，相对于单个大功率发动机的整车布置，可以有效缩短整车长度，减轻整车重量；通过双发动机和电机的合理控制，可以有效降低燃油消耗；发动机A可全功率发电输出给车载用电设备，输出功率大且发电品质高，可实现行进中发电。
应当理解的是，以上仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本领域的技术人员在本发明所揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
