The invention relates to a power assembly suspension and a vehicle. The power assembly suspension is used for supporting a power assembly on a vehicle frame in the first direction and comprises an elastic part, the two opposite sides, in the first direction, of the elastic part are used for being connected with the vehicle frame and the power assembly correspondingly, and the elastic part is provided with a first cavity and two second cavities which penetrate through the elastic part in the second direction; the two second cavities communicate with the two opposite sides, in the third direction, of the first cavity correspondingly, the first cavity is provided with two first cavity walls oppositely arranged in the first direction, the two first cavity walls are perpendicular to the first direction correspondingly, and the two first cavity walls are constructed to be capable of making surface contact when the elastic piece elastically deforms in the first direction; and the first direction, the second direction and the third direction are vertical pairwise. According to the power assembly suspension, when a vehicle is under the extreme working condition, the two first cavity walls can be in surface contact, the contact area in the elastic piece is increased, the rigidity of the elastic piece is improved, and the tearing risk of the elastic piece under the extreme working condition is reduced.
本申请涉及一种动力总成悬置及车辆。动力总成悬置用于将动力总成沿第一方向支撑于车架上,动力总成悬置包括弹性件,弹性件沿第一方向的相对两侧分别用于与车架和动力总成连接,弹性件上设有均沿第二方向贯穿弹性件的第一腔和两个第二腔,两个第二腔分别与第一腔沿第三方向的相对两侧连通,第一腔具有沿第一方向相对设置的两个第一腔壁,两个第一腔壁分别与第一方向垂直,且两个第一腔壁被构造为能够在弹性件沿第一方向发生弹性变形时面接触,其中,第一方向、第二方向和第三方向两两垂直。上述动力总成悬置,当车辆在极端工况下两个第一腔壁能够面接触,增加了弹性件内部的接触面积,增大弹性件的刚度,降低了极端工况下弹性件撕裂风险。
