The invention discloses a reinforcing plate assembly of an auxiliary frame, the auxiliary frame and a vehicle. The reinforcing plate assembly comprises a first reinforcing plate and a second reinforcing plate, the second reinforcing plate is positioned below the first reinforcing plate; the third reinforcing plate is arranged between the first reinforcing plate and the second reinforcing plate, and a first closed structure is defined between the third reinforcing plate and the first reinforcing plate and between the third reinforcing plate and the second reinforcing plate. The connecting strength between the first reinforcing plate and the second reinforcing plate and the structural strength of the third reinforcing plate are improved, the overall structural strength of the reinforcing plate assembly can be improved, vibration transmitted to the auxiliary frame by the reinforcing plate assembly is reduced, and therefore vibration transmitted to a vehicle body is reduced, and the sensitivity of vibration transmission is reduced. Energy transmitted by vibration noise is effectively attenuated, the purpose of reducing the vibration noise in the vehicle is achieved, and the riding comfort of a user is improved.
本发明公开了一种副车架的加强板组件、副车架和车辆,加强板组件包括:第一加强板;第二加强板,所述第二加强板位于所述第一加强板的下方;第三加强板,所述第三加强板设置于所述第一加强板和所述第二加强板之间,且所述第三加强板与所述第一加强板和所述第二加强板之间限定出第一闭合结构。提升第一加强板和第二加强板之间的连接强度,以及第三加强板自身的结构强度,可以提升加强板组件的整体结构强度,减小加强板组件传递至副车架的振动,从而减小传递至车身的振动,降低振动传递的灵敏度,有效地衰减振动噪声传递的能量,达到降低车内振动噪声的目的,改善用户乘坐舒适性。
