A quadrangular leaf spring of a quadrangle for generating vibration within a linear vibration motor includes a bottom support having an outer edge of a square form, a top support having a given height with respect to the bottom support and moved up and down by an elastic force of an elastic leg part, and the elastic leg part connected to an inside of the bottom support and upward extended up to the top support. A portion where the elastic leg part and the bottom support are connected is closer to a corner than to a center of each side of the bottom support. A right line of a portion of the elastic leg part connected to the bottom support is extended from the bottom support to the upper side in a concave shape with respect to the center of the leaf spring.

A spring element that includes one or more loop portions. Each loop portion provides vibration isolation characteristics for the spring element. One or more fastening portions of the spring element enable the fastening or connecting of the spring element to one or more structures. A ratio of a longitudinal measure of each loop portion to a transverse measure of the spring element is between 7.5 and 500. A pair of loop portions may be integrally joined together at a middle section to form a continuous loop. A pair of fastening portions may be integrally joined to opposing sides of the middle section, respectively. One of the fastening portions may be connected to a first structure and the other one of the fastening portions may be connected to a second structure.

In a method for producing a spring leaf (2) for a leaf spring, in particular a parabolic spring or suspension spring, wherein the spring leaf (2) comprises two end regions, a central region, a top side which is subjected to tensile stress in the operative state, and a bottom side (1) which is subjected to pressure in the operative state, at least one hole (3) is introduced into the bottom side (1). The bottom side (1) is peened locally in the region around the hole (3).

A spring for use in conjunction with a vehicle, in particular a leaf spring (1), preferably a parabolic spring, has a single-part spring leaf (12) made of steel, in particular spring steel, having a central region (2) and two adjoining edge regions (4a, 4b), wherein the edge regions (4a, 4b) each have an end region (5a, 5b), the end regions (5a, 5b) can each be connected to a chassis in a stationary manner via a rolled eye (11), and the total length of the spring when installed on the vehicle is substantially unchangeable in all load states. In the unloaded state, the spring leaf (12) has two bending sections (13, 14), which each have a curvature with a curvature direction, wherein the curvature directions of the two bending sections (13, 14) are opposed, and the two bending sections (13, 14) merge into each other in the region of a turning point (15). The first bending section (13) is a vertical spring section and runs from the end region (5a) of the first edge region (4a) via the central region (2) to the turning point (15). The second bending section (14) is a horizontal and vertical spring section and runs from the turning point (15) to the end region (5b) of the second edge region (4b).

A steering assembly having an inner steering member; an outer member, where the inner steering member is adapted to translate relative to outer member; and a bearing component disposed around a portion of the inner steering member, where the bearing component includes a bearing having a unitary substrate and a polymer layer overlying the substrate, where the bearing has a generally arcuate shape and is adapted to support the inner steering member disposed in the outer member, where the bearing has a support region for supporting an inner steering member, and a plurality of feet comprising a first foot and second foot spaced apart from each other such that the support region extends there between, and where the first and second feet extend in radial direction beyond the support region such that upon assembly between inner steering member and outer member, wherein the bearing exerts a force against the inner steering member.
