The invention relates to a drive motor suspension system which comprises a left longitudinal beam assembly, a right longitudinal beam assembly and an auxiliary frame assembly fixedly connected between the left longitudinal beam assembly and the right longitudinal beam assembly. The motor assembly is located on the front side of the auxiliary frame assembly and located between the left longitudinal beam assembly and the right longitudinal beam assembly. The suspension unit comprises a left bracket connected to the left longitudinal beam assembly and a right bracket connected to the right longitudinal beam assembly; the left elastic support assembly is connected to the left bracket, and the right elastic support assembly is connected to the right bracket; the left support is connected between the left elastic support assembly and the motor assembly, and the right support is connected between the right elastic support assembly and the motor assembly; the rear suspension support is connected to the auxiliary frame assembly, and the rear suspension assembly is connected between the rear suspension support and the motor assembly. According to the suspension unit, the decoupling rate of the suspension unit is increased, the bearing reaction of each suspension point is reduced, and the displacement of each suspension cushion is reduced, so that the reliability of a system is improved.
本申请涉及一种驱动电机悬置系统,包括:左纵梁总成和右纵梁总成,以及固定连接在左纵梁总成和右纵梁总成之间的副车架总成;电机总成,其位于副车架总成的前侧且位于左纵梁总成和右纵梁总成之间;悬置单元,其包括连接在左纵梁总成上的左托架,连接在右纵梁总成上的右托架;连接在左托架上的左弹性支架总成,连接在右托架上的右弹性支架总成;连接在左弹性支架总成和电机总成之间的左支架,连接在右弹性支架总成和电机总成之间的右支架;连接在副车架总成上的后悬置支架,连接在后悬置支架与电机总成之间的后悬置总成。本申请提高了悬置单元的解耦率、降低了各悬置点的支反力、降低了各悬置软垫的位移量,从而提高了系统的可靠性。
