摘要： 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.

摘要： The invention provides rear suspension structures and engine cradles involving tubular components. The tubular components have variable wall thickness along the length for reducing materials required. The tubular components also have mechanical properties varying along the length of the tubular components, to meet the requirements on strength and dynamic and static loads. The weight of the tubular components can be further reduced by appropriately varying the wall thickness and mechanical properties along the length of the tubular components.

摘要： In a vehicle rear suspension, each of right and left trailing arms (1) is bent upward at a bent part in an intermediate area between a front end cylindrical portion (2) and a rear end portion (3) so that the trailing arms (1) can be bent. Each end of a torsion beam (7), having a substantially U-shaped cross-section, is connected to an upward inclining area of each trailing arm (1) inclining from the rear end portion (3) toward the bending part (6). This makes it possible to arrange the torsion center of the torsion beam (7) having the substantially U-shaped section in a relatively high position and to maintain the strength of the torsion beam (7) at a high level.

摘要： A torsion-bar-free, unitary, twist beam axle having stress transition character capable of handling both vehicle suspension bending loads and torsion loads without a separate torsion bar, comprising a one-piece, integral twist beam elongated in the direction of its axis, and having a pair of legs elongated in the direction of the axis and extending transverse to the axle axis to outer distal ends, the legs each having an elongated portion looped back upon itself into elongated, peripherally closed loops at said outer distal ends to form a pair of closed loops spaced from and generally parallel to each other, the axle having a central portion, and a pair of mounting ends for attachment to vehicle trailing arms, and a pair of stress transition members extending respectively from the mounting ends toward the central portion and located substantially between the closed loops, these members having a pair of spaced walls connected by a bight and with sufficient resistance to flexing movement toward each other to limit movement by the loops toward each other and to limit loop movement in opposite axial directions along the axis, under torsional stress applied to the axle. The ends of these walls are shown to curve under the loops for weldment thereto. The stress transition members taper in height along their length, from the highest height at the inner ends thereof.

摘要： In a rear axle for motor vehicles, which includes a torsionally-yielding cross member fixed at its ends to two trailing arms carrying the wheel spindles, the cross member has a channel section with a base wall which is disposed upwardly, and two downwardly-inclined end portions. To the ends of the cross member are fixed two tile-shaped reinforcing members which, together with the inclined end portions of the base wall of the cross member, form two box structures defining two bracket-shaped connecting parts in which the two trailing arms are engaged and welded. The tile-shaped reinforcing members are provided with supports for a pair of helical suspension springs of the axle.

摘要： A torsion beam suspension includes a pair of lateral trailing members, each of which has a front end portion pivotally supported by a vehicle body and also has a rear end portion adapted to suspend wheels. The suspension also includes a torsion beam adapted to have an open face, in which a vehicle front side or a vehicle rear side thereof is opened, and arranged to extend in a lateral direction of a vehicle. Intermediate portions of the pair of trailing members are respectively bonded to corresponding end portions of the torsion beam. On an inner side wall of each of the trailing members, a patch member connecting a corresponding one of the trailing members to the torsion beam is disposed.

摘要： A suspension and axle assembly is provided having two identical stampings, each of which form a portion of an axle and a portion of first and second suspension control arms that extend from the axle. The two stampings are coupled to one another along a continuous weld path. The assembly eliminates the connection points between the axle and control arms. The assembly also defines a pair of bores in which springs may be disposed at varying heights to lower the vehicle floor and reduce loads on the control arms, bushings, and other joints.
