The invention discloses an automobile longitudinally-arranged engine suspension installation beam assembly which comprises a beam, suspension installation supports and a beam connecting support, the middle position of the beam is in a V shape, and the two suspension installation supports are arranged on the two sides of the beam in a welded mode. The two ends of the cross beam are connected with the cross beam connecting supports in a screwed mode respectively, and the cross beam is fixed between the lower vehicle body left longitudinal beam and the lower vehicle body right longitudinal beam through the cross beam connecting supports and used for installing an engine assembly. The mounting bracket and the connecting cross beam structure thereof are optimized, the cracking problem of the engine suspension mounting bracket is solved, and the reliability is high; the Y-direction rigidity of the lower vehicle body is improved, the torsional deformation amount in the vehicle running process is reduced, the service life of other parts on the upper vehicle body is prolonged, the vibration isolation performance and the whole vehicle NVH performance are improved, and the rear suspension can be applied to a longitudinally-arranged engine of an automobile in a platform mode.
本发明公开了一种汽车纵置发动机悬置安装横梁总成,包括横梁、悬置安装支架和横梁连接支架,所述横梁的中间位置呈现“V”字型,两个悬置安装支架采用焊接的形式设置在横梁两侧,横梁两端分别采用螺接的方式连接横梁连接支架、并通过横梁连接支架固定在下车体左纵梁和下车体右纵梁之间,用来安装发动机总成。本发明对安装支架及其连接横梁结构进行了优化,解决了发动机悬置安装支架开裂问题,可靠性高;提升了下车体的Y向刚度,降低车辆行驶过程中的扭转变形量,提高了上车体上其余各零部件的使用寿命,提升了隔振性及整车NVH性能、可平台化应用于汽车纵置发动机上。
