The invention relates to a device for fixing an auxiliary frame, a left longitudinal beam and a right longitudinal beam of a passenger car. The device comprises an auxiliary frame control tire and two swing arm control tires with the same structure, fastening connection among a front overhang front grille, a front overhang rear grille and a left longitudinal beam/a right longitudinal beam in the passenger car auxiliary frame is achieved through the auxiliary frame control tire and the two swing arm control tires of the same structure. In the installation process of the device, by considering parameters such as relative precision deviation of connecting holes among the auxiliary frame, the auxiliary frame control tire, the swing arm control tire, the left longitudinal beam and the right longitudinal beam, fitting gaps, hole coaxiality and the like, installation holes in a front overhang front grille, a front overhang rear grille and the left longitudinal beam and the right longitudinal beam in the auxiliary frame are accurately positioned; therefore, the installation accuracy of devices in the suspension system is improved, and the problem that the suspension system cannot be installed or accurate four-wheel positioning cannot be conducted on a passenger car is solved.
本发明涉及一种用于固定客车副车架和左右纵梁的装置,包括副车架控制胎和两个结构相同的摆臂控制胎;通过副车架控制胎和两个结构相同的摆臂控制胎实现客车副车架中前悬前格栅、前悬后格栅和左/右纵梁之间的紧固连接;在装置的安装过程中,通过考虑副车架、副车架控制胎、摆臂控制胎和左右纵梁之间连接孔的相对精度偏差、贴合间隙和孔的同轴度等参数,从而对副车架中前悬前格栅、前悬后格栅和左右纵梁上的安装孔进行精准定位,以此提升悬挂系统中器件安装的精准度,从而避免出现悬挂系统无法安装或无法对客车进行精准四轮定位的问题。
