The novel auxiliary frame and vehicle body installation structure structurally comprises an auxiliary frame, an installation cross beam and a vehicle body installation cross beam, the auxiliary frame and the vehicle body installation cross beam are connected through a cross beam, the installation cross beam is installed on the auxiliary frame in an embedded mode, the auxiliary frame is in a square frame shape, and a square notch is formed in the lower left corner of the auxiliary frame. By using the mounting cross beam as a mounting pivot between the auxiliary frame and the vehicle body mounting cross beam, firstly, the requirement on the torque of a mounting bolt can be reduced, the grade of the bolt is reduced, and meanwhile, the requirement on the flatness of the auxiliary frame and the vehicle body mounting plane is reduced; a movable variable within the limit threshold value is formed between the auxiliary frame and the vehicle body installation cross beam, so that the vehicle body structure is stabilized, the abnormal sound of movement of the auxiliary frame caused by attenuation of the installation torque of the auxiliary frame in the later period of use of the vehicle is effectively avoided, the reliability of the whole vehicle is improved, and the after-sale maintenance cost is reduced.

    本发明公开了一种新型副车架与车身安装结构,其结构包括副车架、安装横梁、车身安装横梁,所述副车架与车身安装横梁通过横梁连接,所述安装横梁嵌入安装于副车架上,所述副车架为方框状,且左下角设有方形的缺口,通过以安装横梁为副车架、车身安装横梁之间的安装枢纽,一是可以降低对安装螺栓力矩的要求,降低螺栓等级,同时降低对副车架和车身安装平面的平面度要求,二是使得副车架、车身安装横梁之间具有额度阈值内可活动的变量从而稳定车身结构,三是有效避免车辆使用后期由于副车架安装力矩衰减引起的副车架窜动异响,提高整车可靠性,降低售后维修成本。
