The invention relates to the field of automobile parts, in particular to a reinforced bracket structure for improving rigidity of an automobile rear suspension mounting point, which comprises an auxiliary frame upper body and an auxiliary frame lower body, and also comprises a rear suspension support which is connected with the auxiliary frame upper body and the auxiliary frame lower body throughbolts, a rear suspension reinforcing support which is arranged in the auxiliary frame upper body and the auxiliary frame lower body and connected with the rear suspension support; and on the premise that the strength and rigidity of a rear suspension mounting point are met, the arrangement of the rear suspension reinforcing support is capable of reducing the thickness of upper and lower plates ofthe auxiliary frame effectively, lightweight design of the auxiliary frame is facilitated, implementation of a stamping process is facilitated, the rigidity of a local mounting point is improved simply through characteristic ribs, the yield effect is limited, and the local rigidity of the mounting point is effectively improved.
本发明涉及汽车零部件领域,具体是一种提高汽车后悬置安装点刚度的加强支架结构,包括副车架上体与副车架下体,还包括通过螺栓与副车架上体与副车架下体连接的后悬置支架、布置在副车架上体和副车架下体内部且与后悬置支架连接的后悬置加强支架,后悬置加强支架的布置,在满足后悬置安装点强度及刚度的前提下,能够有效的降低副车架上下板料厚,便于副车架轻量化设计,同时便于冲压工艺的实施,且单纯通过特征筋来提高局部安装点刚度收效有限,有效提升安装点局部刚度。
