The invention discloses a gearbox suspension system which comprises a cross beam assembly and a suspension assembly, the cross beam assembly comprises a cross beam body, and the cross beam body comprises a first cross beam, a second cross beam, a connecting plate arranged between the two cross beams and two side plates connected with the two cross beams. Meanwhile, the cross beam assembly is rigidly connected with the frame, so that the torsional rigidity of the area of the frame is increased; the suspension assembly is detachably and flexibly connected with the gearbox, the suspension assembly is also detachably connected with the cross beam assembly, the resonance amplitude of the gearbox and the cross beam assembly can be reduced through the connection mode, and then the vibration comfort of the whole vehicle is improved; in addition, the mounting plate used for mounting the suspension assembly in the cross beam assembly is a bent steel plate, compared with a stamping plate, the rigidity of the mounting surface of the suspension assembly is improved, the vibration isolation performance is further improved, and finally the NVH performance of the whole vehicle is improved.
本发明公开了一种变速箱悬置系统,包括横梁组件与悬置组件,横梁组件包括横梁本体,横梁本体包括第一横梁、第二横梁、设置于两个横梁之间的连接板、以及与两个横梁连接的两个侧板,相较于冲压成型的设计,提升了横梁的刚度和抗扭曲性能,同时横梁组件与车架刚性连接,增加了车架该区域的扭转刚度;悬置组件与变速箱可拆卸的柔性连接,悬置组件与横梁组件之间同样可拆卸连接,这种连接方式能够降低变速箱与横梁组件的共振幅度,进而提升整车的振动舒适性;此外,横梁组件中用于安装悬置组件的安装板为折弯的钢板,相较于冲压板,提升了悬置组件安装面的刚度,进而提升了隔振性能,最终提高了整车NVH性能。
