The invention relates to a suspension device for power assembly vibration isolation, a vibration isolation suspension and a vehicle, and relates to the technical field of automobile vibration isolation devices. The first vibration reduction piece is arranged in the middle of the suspension cross beam, located between the suspension cross beam and the rear suspension support and used for connecting the suspension cross beam and the rear suspension support; and the second vibration reduction pieces are arranged at the two ends of the suspension cross beam and used for connecting the suspension cross beam with the auxiliary frame so as to disperse vibration transmitted by the suspension cross beam to the auxiliary frame. Due to the fact that the first vibration reduction piece firstly weakens vibration transmitted to the suspension cross beam from the power assembly through the rear suspension support, and then the second vibration reduction piece weakens vibration transmitted to the auxiliary frame from the suspension cross beam, the vibration reduction effect is enhanced, the suspension cross beam is connected with the rear suspension support, space utilization is better, and the situation that the rear suspension assembly is not arranged in space, and the rear suspension assembly is not arranged in space is prevented. The problems that in the prior art, a rear suspension assembly is difficult to arrange, and the NVH performance of the whole vehicle is possibly affected after arrangement are solved.

    本申请涉及一种用于动力总成隔振的悬置装置、隔振悬置及车辆,涉及汽车隔振装置技术领域,包括悬置横梁;第一减振件,其设置在悬置横梁中部,并位于悬置横梁与后悬置支架之间,用于连接悬置横梁与后悬置支架;第二减振件,其设置在悬置横梁的两端,用于连接悬置横梁与副车架,以将悬置横梁传递的振动分散至副车架。由于第一减振件先减弱动力总成通过后悬置支架传递到悬置横梁的振动,第二减振件再减弱悬置横梁传递到副车架的振动,加强了减振效果,且通过悬置横梁连接后悬置支架,空间利用更好,防止没有空间布置后悬置总成,解决了现有技术中存在难以布置后悬置总成,布置后也可能影响整车NVH性能的问题。
