The Truck suspension is one of the most important part to decide the durability performance of the commercial vehicle. Since the spring Hanger, a core component for rigid axle supension, directly supports leaf spring, it needs strength and durability. In this paper, X/Y/Z directional durability test was carried out and test objective was the 5 ton truck. The durability test has been conducted under a driving condition of X/Y/Z force mode by usieng hydraulic actuator for spring hanger for commercial vehicle. We"ve also carried out srtuctural analysis by utilizing ANSYSin order to predict for spring hanger durability.

The Truck suspension is one of the most important part to decide the durability performance of the commercial vehicle. Since the shackle & helper stopper, a core component for rigid axle supension, directly supports leaf spring, it needs strength and durability. In this paper, the test objective developed the 5 ton truck, Z directional durability test was carried out shackle & helper stopper. The durability test has been conducted under a driving condition of Z force mode by usieng hydraulic actuator for shackle & helper stopper. We"ve also carried out srtuctural analysis by utilizing ANSYS in order to predict for shackle & helper stopper durability.

This paper suggests how to improve fatigue strength of the drive shaft, which is the vulnerable part of the drive shaft system for the 3.5ton commercial vehicle. Drive shaft is composed of the university joint with spider and yoke, yoke shaft and so on. Improvement of drive were selected shaft inner/ outer yoke shaft spider. Four cases were considering design variables such as length and thickness of spider of drive shaft, fatigue analysis was conducted. Finally, we suggest that be improved drive shaft.
