The invention discloses a welding front auxiliary frame for enhancing rigidity of a control arm, which comprises a left longitudinal beam, a right longitudinal beam, a front cross beam, a rear cross beam, a middle tower steel pipe, a control arm mounting bracket, a front beam, a rear beam, a middle tower steel pipe, a rear tower steel pipe, a front beam, a rear beam, a rear tower steel pipe, a front beam, a rear beam, a rear tower steel pipe, a rear beam, a rear beam, a rear beam and a control arm mounting bracket, and is characterized in that the middle tower steel pipe respectively penetrates through the middle parts of the left longitudinal beam and the right longitudinal beam and is in welded connection with the left longitudinal beam and the right longitudinal beam; the section of the control arm installation support is in a C shape, and the control arm installation support is connected with the rear vehicle body sleeve in a welded mode. According to the welding front auxiliary frame for reinforcing the rigidity of the control arm, the cross section of the control arm mounting bracket and the cross section of the longitudinal beam are both of a C-shaped structure, a vehicle body rear sleeve 10 is welded to the control arm mounting bracket 9, the X, Y and Z rigidity of the control arm bracket is greatly improved through the structure, the structure of the auxiliary frame is redesigned, a control arm reinforcing bracket is additionally arranged, and a stabilizer bar reinforcing bracket is optimized; and the Z-direction static and dynamic stiffness of the stabilizer bar and the control arm is greatly improved.

    本发明公开了一种加强控制臂刚度的焊接前副车架,包括左纵梁、右纵梁、前横梁和后横梁,中塔钢管,所述中塔钢管分别贯穿在左纵梁和右纵梁的中部,且中塔钢管与左纵梁以及中塔钢管与右纵梁之间均为焊接连接,控制臂安装支架,所述控制臂安装支架的截面呈“C”形,且控制臂安装支架与后车身套管之间焊接连接。该加强控制臂刚度的焊接前副车架,控制臂安装支架与纵梁截面均为C型结构,且车身后套管10与控制臂安装支架9焊接,此结构极大的提升了控制臂支架的X,Y,Z刚度,重新设计了副车架的结构,增加了控制臂加强支架,以及优化了稳定杆加强支架,极大的极高了稳定杆以及控制臂的Z向静动刚度。
