The steering system includes a steering wheel, a steering column, an intermediate shaft and a steering gear connected in sequence. The steering intermediate shaft is an important part of the steering system. It is located between the steering gear and the steering column, connecting the two. The main function of the steering intermediate shaft is to transmit steering torque. At the same time, the sliding function of the intermediate shaft itself can produce normal collapse in the event of a head-on collision to alleviate damage to the driver. In actual use, the steering intermediate shaft may experience functional failures such as spline jamming or insufficient spline strength, which undoubtedly poses a major threat to the driver's life safety.
