The invention relates to the technical field of vehicles and discloses a vehicle power assembly damping device. The device comprises a gearbox support, a rear suspension cushion, a rear suspension cross beam, a second damping cushion and vehicle body longitudinal beams, wherein the gearbox support is arranged at the middle of the rear suspension cross beam, the rear suspension cushion is arranged between the gearbox support and the rear suspension cross beam, the vehicle body longitudinal beams are arranged at two ends of the rear suspension cross beam, and the second damping cushion is arranged between the vehicle body longitudinal beams and the rear suspension cross beam. The device is advantaged in that the rear suspension cushion is arranged between the gearbox support and the rear suspension cross beam, and the second damping cushion is arranged between the vehicle body longitudinal beam and the rear suspension cross beam, so a vibration reduction transmission path of a power assembly is improved from first-stage vibration reduction to second-stage vibration reduction, excitation of the rear suspension cross beam to a vehicle body during abnormal vibration is attenuated again, and therefore, abnormal sound in the idling working condition of the vehicle can be effectively reduced, the noise peak value in the acceleration working condition of the vehicle is reduced, and longitudinal beam vibration of the vehicle body is reduced.

    本发明涉及车辆技术领域,公开了一种车辆动力总成减振装置,包括变速箱支架、后悬置软垫、后悬置横梁、第二减振软垫和车身纵梁,所述变速箱支架设置在所述后悬置横梁的中部,所述后悬置软垫设置在所述变速箱支架与所述后悬置横梁之间,所述车身纵梁设置在所述后悬置横梁的两端,所述第二减振垫设置在所述车身纵梁与所述后悬置横梁之间。本发明通过在变速箱支架与后悬置横梁之间设置后悬置软垫,在所述车身纵梁与所述后悬置横梁之间设置第二减振垫,使得动力总成的减振传递路线由一级减振提升为二级减振,起到了再次衰减异常振动时后悬置横梁对车身的激励,从而可有效降低车辆怠速工况时异响,降低车辆加速工况时噪音峰值,降低车身的纵梁振动。
