Abstract: In a design method of torsion bars used for a trunk lid, free shapes of the torsion bars unhitched from the trunk lid are designed. A center line model of the initial free shape is geometrically and statically created on the basis of a design specification. The center line model of an open shape is created from the free shape model and is deformed into a center line model of a closed modified shape. The center line models of the analyzed closed shape and the target closed shape is compared with each other to obtain a difference torque and a difference vector occurring between corresponding nodes on the center lines. The center line model is so changed as to decrease the difference torque and the difference vector.

Abstract: A strut-type suspension includes a compression coil spring, a lower spring seat, an upper spring seat, and a shock absorber. The compression coil spring is disposed at a position offset to the outer side of a vehicle with respect to the shock absorber. The compression coil spring is mounted in a vehicle body in such a state that it is compressed between spring seats. The compression coil spring includes a large-diameter wire portion and a small-diameter wire portion. The large-diameter wire portion is provided in a vehicle inner-side portion of the compression coil spring. The small-diameter wire portion is provided in a vehicle outer-side portion. A wire diameter of the large-diameter wire portion is greater than a wire diameter of the small-diameter wire portion.

Abstract: A knee-action-type suspension is provided with an arm member, a compression coil spring, and a shock absorber. The coil spring is extended and retracted between a full-rebound state and a full-bump state in accordance with the magnitude of a load applied to a vehicle body. A wire of the coil spring includes a large-diameter wire portion, a small-diameter wire portion, and a wire diameter varying portion. The large-diameter wire portion is provided in a first portion of the coil spring, which is on the side near to a pivot. The small-diameter wire portion is provided in a second portion of the coil spring, which is on the side far from the pivot. A wire diameter of the large-diameter wire portion is greater than a wire diameter of the small-diameter wire portion.
