具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图4描述根据本申请的一些实施例提供的多动力混合传动系统100和电动轮设备。其中，电动轮设备包括多动力混合传动系统100，多动力混合传动系统100为电动轮设备提供动力。其中，电动轮设备可以为电动轮矿用自卸车，或满足要求的其他设备，例如，本申请实施例提供的电动轮设备可以为大吨位电动轮矿用自卸车。
其中，大型矿山由于产能需要，通常使用大吨位电动轮设备，其具有载重大、自重大、体积大、功率大等特点。动力系统一般采用单发电机模块，由于单发电机模块采用的发动机、发电机和散热器等零部件功率较大，设备较大型化，国内外可提供对应的成熟机型的厂商和机型较少，且存在零部件价格昂贵，供货周期长，维修换件成本高，配件供货周期长等问题，同时可能存在技术垄断风险。
有鉴于此，如图3和图4所示，本申请第一方面的实施例，提供了一种多动力混合传动系统100，包括：双发电机模组110，双发电机模组110包括结构相同的两个单发电机模块120；电动轮模组130；变流模组140，每个单发电机模块120与变流模组140电连接，变流模组140又与电动轮模组130电连接。
其中，利用结构相同的两个单发电机模块120均与变流模组140电连接，以替换相关技术中的一个较大型化单发电机模块为电动轮模组130提供电能，从而保证双发电机模组110的总输出电功率足够，以确保电动轮设备能够正常运行。由于两个结构相同的单发电机模块120替代相关技术中的一个较大型化单发电机模块，与相关技术中的一个较大型化单发电机模块相比，本申请中的每个单发电机模块120的体积和尺寸较小，成本较低，功率较小，且其内部部件结构尺寸较小，进而能够避免国内外对大功率单发电机模块的技术垄断，使得较多的厂商能够提供满足本申请实施例提供的单发电机模块120以及相关的配件，扩大了单发电机模块120及其配件的供货商，进而能够缩短供货周期，且体积较小的两个单发电机模块120与相关技术中的较大型化的单发电机模块相比，能够分别进行安装和 维修，进而便于安装和维修，有利于节约维换件成本，适于推广应用。
进一步地，组成双发电机模组110的两个单发电机模块120的结构相同，使得两个单发电机模块120的配件可以通用，有利于进一步节约多动力混合传动系统100的维修换件成本。
进一步地，变流模组140用于将两个单发电机模块120的电能合流，并将不稳定的交流电转换为稳定的电流，用于电动轮模组130的驱动或能量存储回收。
在本申请提供的一些可能实现的实施例中，如图3所示，多动力混合传动系统100还包括能量存储模组150，能量存储模组150与变流模组140电连接，用于存储和/或供给能量。具体地，能量存储模组150可以包括动力电池，动力电池与变流模组140电连接，这样，在电动轮设备低功率消耗时，如电动轮设备下坡缓行、制动或减速阶段，利用动力电池能够进行能量回收并储存；在整合大功率需求时，如电动轮设备在上坡阶段，动力电池可以作为功能部件，对电动轮模组130进行动力补充，以辅助电动轮模组130动作，从而达到降低油耗并提高动力性的目的。
进一步地，能量存储模组150为可替换件，如双发电机模组110提供的总功率足够的情况下，即两个单发电机模块120共同提供的功率满足电动轮设备各种工况行驶需求时，可以不设置能量存储模组150，以简化多动力混合传动系统100的结构，减小多动力混合传动系统100的体积，降低多动力混合传动系统100的成本。在双发电机模组110提供的总功率不能够满足电动轮设备各种工况行驶需求时，可以增设能量存储模组150，以确保电动轮设备能够正常运行，且有利于节约能源，降低油耗。
在本申请提供的一些可能实现的实施例中，如图3所示，多动力混合传动系统100还包括电阻栅模组160，电阻栅模组160与变流模组140电连接，用于消耗多余的电能。电阻栅模组160用于在电动轮设备下坡缓行、或制动时，将超出能量存储模组150回收能力范围的电能进行消耗。
在本申请提供的一些可能实现的实施例中，如图3所示，双发电机模组110和电动轮模组130沿第一方向分布在第一中心线211的两侧，第一中心线211为车架总成210与第一方向平行的中心线；流其中，第一方向如图2所示的前后方向，如电动轮设备的前后方向，第二方向如图2所示 的左右方向，如电动轮设备的左右方向。
在本申请提供的一些可能实现的实施例中，如图4所示，单发电机模块120包括散热器121、内燃机122、发电机123和安装架124。其中，散热器121、内燃机122、发电机123依次串联连接，并沿第一方向依次安装在安装架124上，使得单发电机模块120作为一个整体，能够独立进行运输和拆装，进而便于运输和安装。
进一步地，由于本申请实施例利用两个单发电机模块120替代一个较大型的单发电机模块，因此，每个单发电机模块120的功率较小，每个单发电机模块120中的散热器121、内燃机122、发电机123的尺寸均与相关技术中的大型化的单发电机模块中的对应部件的尺寸小，因此，利用安装架124将单发电机模块120中的散热器121、内燃机122、发电机123集成在一起，体积较小，重量较轻，使得单发电机模块120作为一个整体，能够独立拖拽、吊装，进而便于运输和安装。如利用安装架124可以将单发电机模块120快速安装在车架总体上，或者，从车架总成200上拆卸下来。
进一步地，由散热器121至发电机123的方向，单发电机模块120的宽度变小，也就是说，单发电机模块120呈一端宽另一端窄的梯形结构，这样的设置，使得单发电机模块120的外形能够尽量与车架总成200的安装空间相匹配，以使双发电机模组110能够较充分地容纳在安装空间内，减小电动轮设备的体积。
进一步地，多动力混合传动系统100包括控制模组或控制模组内置变流模组140中，这样，在整个电动轮设备在低功率需求时，利用控制模组采用一定的控制策略，使内燃机122在最佳燃油经济性转速工作，从而能够大幅降低油耗。
本申请实施例提供的多动力混合传动系统100，包含动力部分、驱动部分、能量回收部分，动力部分包括双发电机模组110，利用两个结构相同的单发电机模块120构成双动力系统，且采用电驱动。每个单发电机模块120为一个独立的模块，包括内燃机122、发电机123、冷却系统、进气系统、排气系统等。驱动系统包括变流模组140、电阻栅模组160、电动轮模组130等；变流模组140包括变流器，变流器用于将两个单发电机模 块120的电能合流，并将不稳定的交流电转换为稳定的电流，用于电动轮模组130的驱动或能量存储回收。能量回收部分包括能量存储模组150，如能量存储模组150为动力电池，利用动力电池完成动力的回收存储，回收设备下坡、制动和减速时的能量，储存在电池中，上坡时辅助电动轮驱动。电阻栅模组160用于设备下坡缓行制动时，超出动力电池回收能力范围电能的消耗。
本申请第二方面的实施例，如图1和图2所示，提供了一种电动轮设备，包括：车架总成200，以及第一方面任一项的多动力混合传动系统100，多动力混合传动系统100与车架总成200直接或间接连接。由于电动轮设备包括第一方面任一项的多动力混合传动系统100，因此，具有上述多动力混合传动系统100的全部有益技术效果，在此不再一一赘述。
进一步地，任一单发电机模块120与车架总成200可拆卸连接，即每个单发电机模块120可作为一个整体，单独吊装、运输和装配，即每个单发电机模块120可以单独安装在车架总成200上，或从车架总成200上拆卸下来，便于装配和维修。
在本申请提供的一些可能实现的实施例中，如图2所示，车架总成200包括沿第二方向相对设置的两个车架纵梁210，如两个车架纵梁210沿电动轮设备的左右方向布置，车架纵梁210包括沿第一方向相对设置的前端和后端，如前端和后端沿电动轮设备的前后方向布置。多动力混合传动系统100设置在两个车架纵梁210之间的内部，双发电机模组110靠近车架纵梁210的前端设置，电动轮模组130靠近车架纵梁210的后端设置，这样的设置，使得电动轮模组130正好位于车架总成200的后部分，便于与电动轮设备的后桥连接，且能够使多动力混合传动系统100较为合理的布置在车架总成200上。
其中，两个车架纵梁210靠近前端的部分围成前宽后窄的安装空间，双发电机模组110的外部形状与安装空间的形状相匹配，也就是说，双发电机模组110的整体外形也大致为前宽后窄的形状，这样，使得双发电机模组110能够充分利用两个车架纵梁210围成的容纳空间进行布置，并不会增加电动轮设备的整车体积。
在上述实施例中，如图2所示，车架总成200包括第一中心线211， 第一中心线211与第一方向平行，即第一中心线211位于两个车架纵梁210之间，沿设备的前后方向延伸，第一中心线211中的任一点到两个车架纵梁210的距离相等。两个单发电机模块120沿第一中心线211对称分布，能够使两个单发电机模块120合理、均匀地分布在两个纵梁围成的安装空间内，进而有利于提高设备重心的稳定性。
其中，沿车架纵梁210的前端至后端的方向，即沿电动轮设备的前后方向，两个单发电机模块120呈V型设置，且单发电机模块120的散热器121位于V型的开口端，即单发电机模块120的散热器121靠近车架纵梁210的前端设置。由于单发电机模块120由散热器121至发电机123的方向，呈前宽后窄的梯形结构，因此，将尺寸较宽的散热器121靠近V型的开口端设置，尺寸较窄的发电机123靠近V型的尖端设置，并将两个单发电机模块120呈V型设置，有利于进一步减小双发电机模组110的整体尺寸，使得双发电机模组110的整体形状与两个车架纵梁210围成的安装空间相匹配，使得设备的结构紧凑，以较大程度减小设备的整体尺寸。
在上述实施例中，如图2所示，每个单发电机模块120包括第二中心线125，第二中心线125平行于单发电机模块120中的散热器121至发电机123的方向，第二中心线125与第一中心线211之间的夹角大于0°并小于等于20°，即图2中的α满足0°＜α≤20°，以确保双发电机模组110作为整体能够合理地安装在两个纵梁围成的容纳空间内，使得整个设备的结构紧凑，并能够保证整车的宽度。
进一步地，如图1和图2所示，本申请实施例提供的电动轮设备，还包括驾驶室300和车箱500，二者按前后方向设置在车架总成200上，车箱500用于容纳物料。驾驶室300附近设置有护栏400或其他覆盖件，以确保驾驶室300的安全性，提高驾驶人员的人身安全。其中，车架总成200的后端连接有后桥总成600，车架总成200的前端连接有前桥总成800，车架总成200上还连接有燃油系统700，以为内燃机122提供原料。车架总成200还设置有液压系统900和举升系统1000，举升系统1000用于使车箱500抬升或下落，以实现自动卸料或正常行驶。
本申请提供的电动轮设备，如图1至图4所示，通过改变相关技术中的电动轮设备采用的单发电机模块的技术方案，采用相互独立的两个单发 电机模块120组成双发电机模组110，从而保证双发电机模组110的总发电功率足够。该技术方案可以避免国外大功率内燃机122的技术垄断，且可以大幅降低主机的采购成本，同时，通过控制模组调整控制策略，可以提高燃油的经济性，如在设备低功率需求时，采用一定的控制策略使内燃机122在最佳燃油经济性转速工作，从而大幅降低油耗。另外加装能量存储模组150，如加装动力电池，在低功率消耗和下坡缓行阶段进行能量回收并储存，在整合大功率需求时可以作为能量供给，从而达到降低油耗并提高动力性的目的。
本申请提供的包括多动力混合传动系统的电动轮设备，采用两个小功率的单发电机模块120替代相关技术中的大功率发电机模块，能够降低购置成本，便于维修，降低油耗，避免国外技术垄断。
同时，为了更好的利用结构空间，双发电机模组110的布置方式同车架纵梁210一样采用前宽后窄的V形夹角方式布置，即双发电机模组110的整体外形尺寸与车架总成200的两个车架纵梁210围成的安装空间相匹配，能够有效的利用结构空间，使整个设备的结构更为紧凑，保证整车宽度。
