Analysis of Differences in Torsional Stiffness of Steering I-Shaft
The I-shaft is a mechanical transmission mechanism in the steering system that connects the steering column and the steering gear to transmit torque and absorb road excitation.During the starting and driving of the vehicle,the steering system is controlled by the driver in real time.The I-shaft is connected to the steering column above and the steering gear below.With two universal joint,it is the most stress concentrated position of the entire steering system,Torsional stiffness is the ability of the steering shaft system to resist road loads and undergo its own elastic deformation.Therefore,the torsional stiffness of the intermediate shaft is an important parameter to measure the performance of the entire vehicle,and its minimum stiffness must be strictly controlled.
