Abstract

The invention provides a steering knuckle expanding device and assembling method. The steering knuckle expanding device comprises an expanding assembly used for expanding an axial notch; and the expanding assembly comprises a first flaring part used for directly acting on the axial notch, a second flaring part acting on a pair of bosses to expand the axial notch, and a driving mechanism used for driving the first flaring part and the second flaring part synchronously. On the one hand, expanding force between the second flaring part and the bosses in the process that the axial notch is expandedto the needed size is reduced to prevent the situation that the second flaring part cannot bear the expanding force, consequently the second flaring part is disengaged from the bosses, and an expanding failure is caused; on the other hand, expanding force acting on the axial notch by the first flaring part in the process that the axial notch is expanded to the needed size is reduced to prevent damage caused by the first flaring part to the axial notch; and the production efficiency is improved, and the product defective rate is decreased.

Description

technical field [0001] The invention relates to the field of automobile manufacturing equipment, in particular to a steering knuckle spreading device, a strut assembly and a steering knuckle assembly method. Background technique [0002] The front suspension of the current car usually adopts MacPherson suspension. In the MacPherson suspension, the strut assembly and the steering knuckle are interference fit to ensure the reliability of the connection. [0003] Generally, the steering knuckle has a mounting hole matched with the strut assembly, and the wall of the mounting hole has an axial notch, and by adjusting the size of the axial notch to adjust the diameter of the mounting hole, Therefore, the strut assembly can be installed in the installation hole, and the interference fit assembly between the strut assembly and the steering knuckle is realized. [0004] In the process of expanding the axial gap, the existing device for expanding the axial gap often encounters failu...
