Filed: 1988-11-08
Abstract: PURPOSE:To increase fatigue performance remarkably by forming a clean steel of chromium vanadium in a spring and applying quenching, low temperature annealing, shot peening, and electronic polishing in this order. CONSTITUTION:A steel wire containing 0.4 to 0.7% of C in weight, 0.1 to 0.4% of Si in weight, 0.4 to 1.2% of Mn in weight, 0.6 to 1.5% of Cr in weight, 0.1 to 0.3% of V in weight and the rest of Fe and unavoidable impurities is used for the material of a coil spring. The steel wire whose cleanliness is adjusted to below 0.01% is coiled in a specified spring shape. Further, quenching, annealing, shot peening and polishing are applied to finish the surface roughness Rmax below 5mu. Thus fatigue performance can be increased remarkably by removing scale from the surface.

Title: Steering force control mechanism for power steering device
Inventor: OKA SHOJI
IPC: B62D5/083
Filed: 1985-12-18
Abstract: PURPOSE:To facilitate the adjustment for steering force by restraining the relative revolution between an intermediate shaft formed integrally with the first shaft connected to the steering wheel side and the second shaft connected to the steering link side according to the car speed. CONSTITUTION:When the car speed is small, the hydraulic pressure introduced onto the front surface of the pressurizing plate 21 of a restraining mechanism 20 is small. Therefore, the engagement force between the front surface of an intermediate shaft 8 integrally formed with a stab shaft 3 and the pressing plate 21 integrally revolving with a worm 9, namely the restraining force between the intermediate shaft 8 and the worm 9 is weakened by the stability of a return spring 22. Therefore,a torsion bar 12 is twisted by a small steering force, and a relative revolution shift is generated between the stab shaft 3 and the worm 9. Thus, a large assist force is generated by a control valve 4.
