Description

Technical Field

[0001] The invention relates to the technical field of automobile component installation, in particular to a method for installing a suspension end cover. Background Art

[0002] Suspension is a general term for all force transmission connection devices between the frame and axle of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and to buffer the impact force transmitted to the frame or body by uneven road surface, and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. The bushing of automobile suspension generally adopts rubber bushing. The rubber bushing type suspension connects the end cover with the bracket shaft by bolts, and the bushing sleeved on the outside of the bracket shaft is a rubber bushing. Because the suspension needs to transmit the force and torque acting between the wheel and the frame, there are extremely high requirements for the installation of the suspension end cover.

[0003] At present, the installation of the suspension end cover is to fix the end cover on the bracket shaft by tightening the bolts. After tightening the bolts, a torque wrench is used to detect whether the tightening torque of the bolts reaches the set value. If it does not reach the set value, tightening continues. In this method, because the bushing is a rubber part with large elastic stiffness, the rubber bushing will generate a rebound force on the end cover during the tightening of the bolts, and the rebound force generated by the rubber bushing cannot be quantified. Therefore, even when the detected bolt tightening torque reaches the set value, it cannot be determined that the end cover has been completely installed. The quality of the product installed in this way cannot be guaranteed, and the end cover bolts are prone to loosening. In addition, this method needs to stop tightening the bolts every time the inspection is performed. The whole process requires multiple measurements and multiple tightenings, which wastes manpower and material resources. Summary of the invention
