SUSPENSION COIL SPRING - MITSUBISHI STEEL MFG

Title:

SUSPENSION COIL SPRING

Document Type and Number:

WIPO Patent Application WO/2002/083437

Kind Code:

A1

Abstract:

With a coil spring assembled to a suspension device, the spring reaction axis is positioned coincident with or sufficiently close to a load input axis, and the design and manufacture of coil springs are facilitated. A suspension coil spring (10) in a free state is formed so that a coil axis (AC) is bent in V-shape at bend point (PB). The distance from the end turn center (CU) of the upper seating surface (38) to an imaginary coil axis (AI) is an upper inclination quantity (VU), and the distance from the end turn center (CL) to the imaginary coil axis (AI) is a lower inclination quantity (VL). Further, when the suspension coil spring (10) is interposed between spring sheets (22, 24) in the suspension device, it is compressed along a strut axis. Thereby, the spring reaction axis of the suspension coil spring (10) is inclined and offset with respect to the imaginary coil axis (AI) according to the inclination quantities (VU, VL).
