The invention discloses a suspension device for a pure electric vehicle. The suspension device includes a motor main engine, the side edge of the lower end of the motor main engine is connected with afront suspension cushion assembly through a bolt; the lower end of the front suspension cushion assembly is connected with a front suspension installation support through a bolt, the front suspensioncushion assembly is fixed to the front side face of the motor main engine through a bolt, the right suspension cushion assembly is fixed to the right side of the motor main engine and the rear suspension cushion assembly is fixed to the rear side face of the motor main machine. After the three soft cushions are installed; the front suspension cushion assembly is connected with a front suspensionmounting bracket fixed on a lower cross beam of the water tank through bolts; the right suspension cushion assembly is connected with an automobile body through a bolt; the rear suspension cushion assembly is connected with the rear suspension installation support fixed to the auxiliary frame through bolts. By means of the three-point type rubber suspension arrangement, vibration components such as a motor and a speed reducer are isolated from electric appliance components such as a controller and a junction box and isolated from a vehicle body and a chassis, and transmission of vibration impact to the vehicle body is reduced.
本发明公开了一种纯电动汽车用悬置装置,包括电机主机,所述电机主机下端侧边通过螺栓连接有前悬置软垫总成,所述前悬置软垫总成下端通过螺栓连接有前悬置安装支架,本发明将前悬置软垫总成用螺栓固定在电机主机前侧面,右悬置软垫总成固定在电机主机右侧,后悬置软垫总成固定在电机主机后侧面;三个软垫安装好后,再用螺栓将前悬置软垫总成与固定在水箱下横梁的前悬置安装支架连接,用螺栓将右悬置软垫总成与车身连接,用螺栓将后悬置软垫总成与固定在副车架的后悬置安装支架连接,采用三点式橡胶悬置布置,将电机、减速器等振动部件与控制器、接线盒等电器部件隔离,与车身、底盘隔离,减少了振动冲击向车体的传递。
