The invention discloses a front windshield cross beam assembly and a vehicle, the front windshield cross beam assembly comprises a front windshield lower cross beam and a front windshield reinforcing beam, the front windshield lower cross beam is arranged above the front windshield reinforcing beam, a plurality of step parts are arranged on the front windshield lower cross beam, and the step parts are arranged on the front windshield lower cross beam. The multiple step parts are arranged in the length direction and/or the width direction of the front windshield lower cross beam, and the thicknesses of the step parts are different and/or the sizes of the step parts in the length direction of the front windshield lower cross beam are different. The plurality of step parts are arranged in the length direction and the width direction of the front windshield lower cross beam, and the widths or thicknesses of the plurality of step parts are different, so that not only can the overall structural strength of the front windshield cross beam assembly be improved, but also the local modals of the plurality of step parts can be used as vibration absorbers to absorb vibration, and the overall structural strength of the front windshield cross beam assembly is improved. And the excitation vibration transmission energy of the engine is effectively attenuated, so that the purpose of reducing the vibration noise in the vehicle is achieved, and the riding comfort of passengers in the vehicle is improved.

    本发明公开了一种前风挡横梁组件和车辆,所述前风挡横梁组件包括:前风挡下横梁和前风挡加强梁,所述前风挡下横梁设置于所述前风挡加强梁的上方,所述前风挡下横梁上设置有多个台阶部,多个所述台阶部在所述前风挡下横梁的长度方向和/或宽度方向上排布,每个所述台阶部的厚度不同和/或在所述前风挡下横梁的长度方向上的尺寸不同。通过在前风挡下横梁的长度方向和宽度方向上设置多个台阶部,并且多个台阶部的宽度或厚度不同,这样不仅可以提高前风挡横梁组件的整体结构强度,而且还可以利用多个台阶部的局部模态作为吸振器来吸收振动,有效衰减发动机激励振动传递能量,从而达到降低车内振动噪声的目的,改善了车内乘员的乘坐舒适性。
