左悬置1和右悬置2分别位于车身宽度方向的两侧，右悬置2的主动端设置为连接发动机6，右悬置2的被动端设置为连接车身；右悬置2设置为缓冲发动机6前后方向、左右方向和上下方向的震动。
如图3所示，本实施例中，右悬置2为液压悬置，右悬置2上设有上下贯通的多个第四安装孔，通过第四紧固件21穿过第四安装孔将右悬置2安装于发动机6；右悬置2上设有至少两个上下贯通的至少两个第五安装孔，及至少一个第六安装孔，第六安装孔同时沿上下方向和左右方向延伸，通过第五紧固件22穿过第五安装孔将右悬置2安装于车身的左纵梁，通过第六紧固件23穿过第六安装孔将右悬置2安装于车身的左纵梁。
左后悬置3设置为连接车架和燃油车的变速器或混动车的主减速器8，左后悬置3设置为缓冲燃油车的变速器前后方向和左右方向的震动或混动车的主减速器8前后方向和左右方向的震动。
如图4所示，本实施例中，左后悬置3为连杆式结构，连杆大头设有沿竖直方向贯通的第七安装孔，通过第七紧固件31穿过第七安装孔将左后悬置3安装于车架的副车架7；连杆小头设有沿前后方向贯通的第八安装孔32，通过第八紧固件穿过第八安装孔32将左右悬置2安装于燃油车的变速器或混动车的主减速器8。
对于燃油车而言，上述车辆动力总成悬置系统已经能够满足车辆动力总成的安全需求，但对于混动车而言，电机的输出功率较大，会给动力总成增加一个以左后方向为轴线的转动扭矩，上述车辆动力总成悬置系统难以满足电机对支撑能力和隔振能力的要求。在车辆为混动车时，本实施例提供的车辆动力总成悬置系统还包括右后悬置4和悬置支架5，左后悬置3和右后悬置4分别位于车身宽度方向的两侧且车身的后端，右后悬置4的主动端设置为通过悬置支架5连接发动机6，右后悬置4的被动端设置为连接车架；右后悬置4设置为缓冲发动机6前后方向和发动机6上下方向的震动。
如图5所示，本实施例中，右后悬置4为橡胶悬置，右后悬置4上设有至少两个第九安装孔，通过第九紧固件41将右后悬置4的被动端连接于混动车的车架的副车架7；右后悬置4的主动端连接于悬置支架5，悬置支架5上设有多个周向分布的第十安装孔，通过第十紧固件51将悬置支架5连接于发动机6的 缸体。
悬置支架5上设有沿前后方向贯通的穿设孔52，车辆的半轴穿过穿设孔52并通过轴承转动连接于悬置支架5。
本实施例在安装右后悬置4的悬置支架5上设置穿设孔52，通过穿设孔52安装半轴，在穿设孔52内安装轴承，通过轴承使半轴能够相对于右后支架转动，无需再单独为半轴设置支架，右后悬置4和半轴共用同一个支架，不仅能够满足右后悬置4的安装需求，以使右后悬置4能够满足电机对支撑能力和隔振能力的要求，还能够避免右后悬置4的设置增大其占用空间。
本实施例中的车头为前方，车尾为后方，前文的前后方向为图1中所示的X方向；驾驶位为右侧，副驾驶位为左侧，前文的左右方向为图1中所示的Y方向，上下方向记为实际的高度方向，前文的上下方向为图1中所示的Z方向。
