Description

一种中重卡48V***应用结构
技术领域
本发明涉及一种48V***应用结构，更具体的说涉及一种中重卡48V***应用结构，属于汽车发动机技术领域。
背景技术
当前，国家对于环境保护越来越重视，对于排放的要求越来越严格，2018年1月全国范围内实施了国V排放标准；另外，从国家的能源安全角度来看，汽车用石油消费占到了石油消费总量的六成，因此，不管是乘用车还是商用车，生产更节能的汽车成了必然选择。
48V混动***的成本在7000元左右，与传统车和重度混合的新能源车相比，其性价比较高。目前，48V***已经在部分乘用车上批量应用，平均能够节油8-10％，克服了低压***功率小电流过大的问题，能够实现汽车启停、动力辅助、刹车能量回收、扩展启停等功能，使发动机始终运行在最佳工况之间，消除了发动机在怠速工作时的油耗、排放与噪声，消除了发动机突然加速、刹车工况下产生的油耗。但是，由于中重卡发动机的启动功率和启动扭矩较大，使得48V***在中重卡上应用仍然存在***电流过大的缺点，因此导致48V***不能直接在商用车领域应用。
发明内容
本发明的目的在于针对现有的48V***不能直接在商用车领域应用的缺陷，提供一种中重卡48V***应用结构。
为实现上述目的，本发明的技术解决方案是：一种中重卡48V***应用结构，该48V***包括BSG电机、逆变器、48V锂电池和DCDC转换器，所述的BSG电机与逆变器连接，所述的逆变器与48V锂电池连接，所述的48V锂电池与DCDC转换器连接，本应用结构还包括发动机和两套48V***，所述两套48V***中的BSG电机均通过皮带与曲轴小轮连接，两套48V***中的DCDC转换器分别与12V电池连接，该两个12V电池串联用于整车电气供电。
所述的两套48V***中一个BSG电机布置在发电机位置，另一个BSG电机布置在空调压缩机位置。
与现有技术相比较，本发明的有益效果是：
本发明使用了两套48V***，通过皮带共同连接在曲轴小轮上，实现48V***在中重卡发动机上的应用。每套***工作时能够分担一半的电流，能够降低使用时线路及元器件的发热，解决了目前中重卡应用48V***时，使用一套***，电流过大，造成了线路发热严重、需要冷却***，成本高昂等问题。
附图说明
图1是本发明结构框图。
图中，皮带1，离合器2。
具体实施方式
以下结合附图说明和具体实施方式对本发明作进一步的详细描述。
参见图1，一种中重卡48V***应用结构，该48V***包括BSG电机、逆变器、48V锂电池和DCDC转换器，所述的BSG电机与逆变器连接，所述的逆变器与48V锂电池连接，所述的48V锂电池与DCDC转换器连接。本应用结构包括发动机和两套48V***，动力连接方式为将所述两套48V***中的BSG电机均通过皮带1与曲轴小轮连接，BSG电机的启动功率在5-20KW，BSG电机的启动扭矩在20-80Nm；皮带1与发动机连接，发动机与离合器2连接，离合器2与变速箱连接，变速箱与主减速器连接，主减速器与车轮连接。因中重卡采用的电气***均为24V***，现有市面上成熟的DCDC转换器为48V转12V的，故我们将两个12Vv的电池串联起来为整车供电，具体为：两套48V***中的DCDC转换器分别与12V电池连接，两个12V电池串联用于整车电气供电；即48V锂电池通过DCDC转换成12V的电压、充进12V的电池中，然后将两套48V***中的两个12V电池进行串联给中重卡24V电气***供电。
参见图1，所述的两套48V***中一个BSG电机布置在发电机位置；另一个BSG电机布置在空调压缩机位置，并用电动压缩机取代机械压缩机。
参见图1，本中重卡48V***应用结构，采用两套48V***为商用车发动机提供启停、动力辅助、能量回收。当48V***做启动发动机使用时，两套48V***的BSG电机通过皮带1将启动扭矩传递给曲轴小轮，带动曲轴、进而启动发动机；当48V***做动力辅助时，两套48V***的BSG电机通过皮带输出功率给曲轴小轮，进而给发动机提供更大的动力；当48V***实现刹车能量回收功能时，发动机通过曲轴小轮反向拖动两套BSG电机，BSG发电将能量充进相应的电池。
具体实施例1：
参见图1，采用两套48V***，电池为48V20AH，配合逆变器、BSG电机和DCDC转换器，其中BSG电机的功率为5KW、启动扭矩为20Nm，然后将两个BSG电机通过皮带1接在曲轴小轮上，实现发动机的启停、动力辅助，能量回收功能。
具体实施例2：
参见图1，采用两套48V***，电池为48V20AH，配合逆变器、BSG电机和DCDC转换器，其中BSG电机的功率为10KW、启动扭矩为40Nm，然后将两个BSG电机通过皮带1接在曲轴小轮上，实现发动机的启停、动力辅助，能量回收功能。
具体实施例3：
参见图1，采用两套48V***，电池为48V20AH，配合逆变器、BSG电机和DCDC转换器，其中BSG电机的功率为20KW、启动扭矩为80Nm，然后将两个BSG电机通过皮带1接在曲轴小轮上，实现大排量发动机的启停、动力辅助，能量回收功能。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，上述结构都应当视为属于本发明的保护范围。
