Publication number: 20100083744Abstract: An inventive load apparatus for performance evaluation of a steering system has a simple construction and yet is capable of faithfully reproducing a tire load observed when the steering system is actually mounted on a motor vehicle. A compression load spring device (12) includes a piston (18) which is axially movable within a cylinder (17), and a pair of springs (20, 21) which resiliently urge the piston (18) to hold the piston (18) in a force balanced state at a neutral position in the cylinder. The piston (18) is connected to a rod (19) having one end (19a) serving as a load output portion. A load outputted from the load output portion (19a) is multiplied by a preset factor by means of a lever mechanism (13), and the resulting load is applied to the steering system (30).Type: ApplicationFiled: December 12, 2007Publication date: April 8, 2010Applicant: JTEKT CorporationInventors: Hiroshi Obata, Terutaka Tamaizumi
