The invention relates to a power assembly suspension device and a vehicle. The suspension device comprises a first support, a damping mechanism, a second support and two elastic limiting bodies, and the first support comprises a limiting frame; the damping mechanism comprises a main spring, the main spring is connected to the inner wall of the limiting frame, the second support comprises a connecting body and a support body, the connecting body is arranged at the top of the main spring, and the support body is connected to the connecting body and extends outwards from an opening of the limiting frame; and each elastic limiting body comprises a first elastic layer, a mass body and a second elastic layer. The limiting frame structure is arranged in the first support, the main spring is arranged in the limiting frame structure, the main spring is connected with the second support through the connecting body, the mass bodies are additionally arranged in the elastic limiting bodies, and themass bodies and the elastic limiting bodies form dynamic vibration absorbers. The device is high in overall integration degree, when a power assembly is in a small-displacement or large-displacementoperation working condition, the elastic limiting bodies integrated with the dynamic vibration absorption function can achieve good vibration absorption and vibration isolation functions in a free state or a compressed state, and the purposes of vibration reduction and noise reduction are achieved.
本发明涉及动力总成悬置装置及车辆,悬置装置包括第一支架、减振机构、第二支架和两弹性限位体,第一支架包括限位框;减振机构包括主簧,主簧连接于限位框内壁上,第二支架包括连接体和架体,连接体设于主簧顶部,架体连接于连接体上并自限位框的敞口处向外延伸;弹性限位体包括第一弹性层、质量体和第二弹性层。通过在第一支架中设置限位框结构,限位框结构中设置主簧,主簧通过连接体连接第二支架,弹性限位体中增加质量体,质量体与弹性限位体构成动态吸振器。装置整体集成度高,并且动力总成处于小位移或大位移运行工况下,集成动态吸振功能的弹性限位体在自由状态或压缩状态下,均能够起到较好的吸振和隔振功能,达到减振降噪的目的。
