The invention provides a frame type auxiliary frame structure. A left front vehicle body mounting point and a left middle vehicle body mounting point are arranged on a left longitudinal beam, and a right front vehicle body mounting point and a right middle vehicle body mounting point are arranged on a right longitudinal beam; a reinforcing plate is arranged between the two lower plates; a left rear vehicle body installation point and a right rear vehicle body installation point are symmetrically arranged on the two lower plates respectively, the auxiliary frame and the vehicle body are connected in a six-point mode, the auxiliary frame can be connected with the vehicle body and a suspension, and the rigidity of the vehicle body can be improved through the auxiliary frame. In addition, the front auxiliary frame further plays a role in supporting an engine, an air conditioner compressor and a gearbox, the full-frame auxiliary frame can absorb part of impact force generated during front collision of an automobile, the problem of connection between the auxiliary frame and an automobile body is effectively solved, and the problem that the auxiliary frame is torn due to stress concentration and long-term repeated fatigue movement in the long-term use process is solved.
本发明提供一种框式副车架结构,通过在左纵梁上设置有左前车身安装点和左中车身安装点,右纵梁上设置有右前车身安装点和右中车身安装点;两下板之间设置有加强板;两下板上分别对称设置有左后车身安装点和右后车身安装点,副车架与车身用六点连接方式,副车架可以连接车身和悬架,副车架可以提高车身的刚性。前副车架还起到支撑发动机、空调压缩机和变速箱的作用,全框副车架可以吸收汽车正面碰撞时的部分冲击力,有效的解决副车架与车身连接问题,长期使用过程中避免了副车架由于应力集中,经过长久反复的疲劳运动,会发生撕裂的问题。
