The invention discloses a reinforcing connection structure of a front auxiliary frame, and belongs to the field of front auxiliary frame structures. According to the reinforcing connection structure, a first reinforcing plate and a second reinforcing plate which are connected are arranged between a rear floor cross beam and a shelf cross beam and are arranged in the vertical direction, so that the bending rigidity of a wheel cover in the vertical direction is larger, and the service life of the wheel cover is prolonged. The vertical excitation of the attenuation road surface is more obvious; meanwhile, the first reinforcing plate, the second reinforcing plate and the wheel cover inner plate form a cavity beam structure, transmission and dispersion of stress of the wheel cover inner plate and absorption of collision energy at the rear end can be optimized, the rigidity and strength are improved, meanwhile, the safety coefficient of the rear end of a vehicle body is improved, and the rigidity of the front auxiliary frame is enhanced; according to the structure, through connecting and assembling of all structural components, the structural requirement is met, and the structural mode is improved; the connecting rigidity and modality of the front auxiliary frame are improved, the supporting performance of the auxiliary frame is more stable, the modality is higher, the motor modality is effectively avoided, resonance is avoided, and the safety and comfort of a vehicle are improved.
本发明公开了一种前副车架的加强连接结构,属于前副车架结构领域,本加强连接结构通过在后地板横梁和搁物板横梁之间设置了相连的第一加强板和第二加强板,并且采用竖直方向布置,使得轮罩在竖直向的弯曲刚度更大,衰减路面竖直向的激励更明显;同时,第一加强板、第二加强板和轮罩内板三者形成空腔梁结构,能优化轮罩内板应力的传递和分散,以及后端的碰撞能量的吸收,提升刚度强度的同时,提升车身后端安全系数,增强了前副车架的刚度;本结构通过各结构组件之间的连接装配,满足了结构需求,提高了结构模态;提高前副车架的连接刚度和模态,使副车架的支撑性更加稳固,模态更高,有效避开电机模态避免共振,提升了车辆的安全性和舒适性。
