The steering column has good energy absorption effect, can continue steering after collapsing, and the mounting bracket can absorb part of energy after collision;
the electric steering column needs to perform sufficient correlation performance verification on a column sample in the development process, and is mainly used for detecting abnormal sound of the steering column, wherein the abnormal sound of the steering column is mainly because: the bearing hole on the bearing hole seat is mainly matched with the bearing bowl of the cross shaft, if the bearing hole is too large, the bearing bowl and the bearing hole are easy to have gaps, the gaps in the rotation direction of the steering column are directly reflected, impact can occur when the steering column is applied with a load with a certain torque to perform forward and reverse torsional movement, and abnormal sound is generated; and the riveting on the bearing hole seat is formed by punching and riveting after the cross shaft and the bearing hole seat are assembled. If the punching and riveting force is too small, the riveting mark is shallow, so that the axial float of the baffle bearing bowl cannot be realized; if the riveting force is too large, the bearing hole is deformed to a certain extent, so that the bearing bowl is extruded, and the arrangement of the needle rollers is damaged, so that when the steering column is loaded with a certain torque to perform forward and reverse torsional movement, the needle rollers are extruded and bumped to generate fine-pointed abnormal sound.
