Description

电动汽车驱动单元
技术领域
本发明涉及电动汽车制造技术领域，尤其是一种用于驱动电动汽车的电控单元。
背景技术
电动汽车驱动单元是将车载电源为动力来源转化为需要的功能动作曲线连续或者间断输出实现驱动的装置，现有的电动汽车驱动单元包括有各自独立的通过连接线连接的电机、电机控制器、空调压缩机、车载充电机及高压配电盒，其受安装布置的局限，外部有复杂高压线路及冷却管路，因此存在着这些器件布置安装支点要求多及由此导致的高压线缆及冷却管路复杂、电磁兼容设计难度大和高压、冷却液若泄露不易检修，其运行风险大的问题。
发明内容
本发明所要解决的技术问题是提供一种电动汽车驱动单元，这种电动汽车驱动单元可以解决多个控制器布置安装支点要求多及由此导致的高压线缆及冷却管路复杂、电磁兼容设计难度大及高压、冷却液若泄露不易检修，其运行风险大的问题。
为了解决上述问题，本发明所采用的技术方案是：这种电动汽车驱动单元，包括有层叠集成设置的高压电源分配模块、车载充电模块、控制模块和执行模块，所述高压电源分配模块分别与DCDC转换器接口、电池加热器接口、动力电池组接口、直流充电接口、电动空调接口、PTC接口、控制输出接口对应相接，所述高压电源分配模块通过车载充电模块与交流充电接口相连接，所述控制输出接口通过控制模块与执行模块相连接；所述高压电源分配模块与所述车载充电模块之间设置有第一冷却层，所述控制模块与所述执行模块之间设置有第二冷却层，所述执行模块包括有与电机相连接的减速器和电动压缩机，所述电机外围绕有第三冷却层；所述第一冷却层、第二冷却层和第三冷却层通过管路连成相通的环路。
上述技术方案中，更具体的技术方案还可以是：所述电池加热器接口和所述交流充电接口分别通过各自串接的继电器和熔断器与所述高压电源分配模块对应相接，所述DCDC转换器接口、所述PTC接口和所述电动空调接口通过各自的熔断器与所述高压电源分配模块对应相接；所述直流充电接口通过其串接的继电器与所述高压电源分配模块对应相接。
由于采用了上述技术方案，本发明与现有技术相比具有如下有益效果：
1、由于车载充电模块、控制模块和执行模块、电动压缩机从上往下层叠集成设置；使用时，可通过悬置系统将其集成后的整体安装在动力舱内，输出传动轴通过执行模块中心贯通空心轴直接连接左、右前车轮驱动车辆执行模块。不仅具备驱动、充电、高压控制、空调系统驱动的功能，还无外部复杂高压线路，冷却回路流通路径短，布置简洁；同时，由于取消了大量的高压连接器，成本大幅降低， 内部连接提高了系统的连接可靠性及防护能力，能够快速平台化移植到其他车型，缩短电动汽车开发验证周期；
2、由于在高压电源分配模块与车载充电模块之间设置有第一冷却层；控制模块与执行模块之间设置有第二冷却层，执行模块的电机外围绕有第三冷却层，并且第一冷却层、第二冷却层和第三冷却层通过管路连成相通的环路；不仅能将各模块产生的热量有效传导，还方便对冷却液泄露的检修；
3、由于在高压电源分配模块与各接口之间设置了熔断器，可对过流进行有效保护。
