No.5（2010）2.Development of an all-purpose jig for the fatigue testing of steering-wheel hubs

Takeshi Konishi, Shigenobu Shimada, Yasuaki Ichikawa

  The steering wheel hub (called hub, hereafter) is a product that connects the steering wheel and the steering wheel shaft in a car. It has the important function of directing the car in the intended direction. There are two fatigue test standards by which to test the hubs; one is JASO C713 for genuine products, and the other is the ASEA standard of NAPAC for aftermarket products. Since the hubs may have different shapes, some jigs are needed to fit into between the hubs and the testing machine when testing. The authors have developed a new jig system for the fatigue test for the hubs. The new jig has a specific feature enabling it to be applied to any hub. Moreover, it has a self alignment mechanism so that the defined testing force is applied to the hub directly and properly.
