摘要： A leaf spring vehicle suspension system includes a chassis rail. Also included is an axle. Further included is a first stage leaf spring operatively coupled at a first end and a second end to the chassis rail, the first stage leaf spring formed of a single steel spring plate and having a first length. Yet further included is a second stage leaf spring operatively coupled to the first stage leaf spring in a stacked arrangement proximate the axle, the second stage leaf spring formed of a composite material and having a second length that is less than the first length of the first stage leaf spring.

摘要： A spring, in particular a flat spring (5), for use in connection with a vehicle, has a middle region (6) which has a curve with a first curve direction, as well as two edge regions (7). In an unladen state, the edge regions (7) each have a curve with a second curve direction and vertices (10), with the second direction of curve being opposed to the first direction of curve. The flat spring (5) has a vertex axis (11) running through the vertices (10) of the curves of the edge regions (7). End regions (8) of the edge regions (7) are tilted away from the vertex axis (11) toward the side of the vertex axis (11) on which the middle region (6) lies.

摘要： Described is a fibre composite component designed as a spring, comprising at least one spring section and at least one force transfer structure (2). In the end portion forming or surrounding the force transfer element (3) the fibre composite material of the fibre composite component (1) is divided, in a plane perpendicular to the longitudinal direction of the force transfer structure (2), into at least two fibre composite material strands (4, 4.1, 4.2). Two adjacent fibre composite strands (4, 4.1, 4.2) nm in opposite directions, overlapping over a specific angular portion and each forming an eye, with their mutually opposed side faces (7) force-transmittingly connected in the overlapping portion.

摘要： The present invention is a seat bottom suspension system adapted to provide a varying spring constant. An embodiment includes a first plurality of flat elongated biasing members in communication with at least one axle adapted to translate in a direction generally parallel with the longitudinal axis of the flat elongated biasing members. An embodiment may include a second set of flat elongated biasing members set at a lower height than the first plurality of flat elongated biasing members to provide a progressive increase in the spring constant as the down force seen on the seat increases.

摘要： A leaf spring, particularly for articulated mechanical structures, includes at least one longitudinally extended elastic element and a pair of rigid elements which are configured to be associated with an articulated mechanical structure. Each one of the rigid elements is coupled rigidly, at a first end thereof, to a respective end of the elastic element. The elastic element is not associated with any constraint or load between its two ends.

摘要： A leaf spring made of a fiber composite material having integrated bearing holes and a method for producing is disclosed. The method comprises the steps of cutting prepreg strips of a predetermined length from a prepreg strand, removing cut-outs from the particular prepreg strip in the axial ends where a bearing hole should be formed, laying a plurality of prepreg strips one over the other in a prepreg stack in alternation so that the surfaces of the prepreg strips are flush to form a raw leaf spring forming a bearing hole by deforming an axial end of the prepreg stack in a plane perpendicular to the longitudinal extension (L) and perpendicular to the transverse extension (B) of the prepreg stack, setting the raw sheet spring to form the finished leaf spring in a mold with a suitable setting pressure and a suitable setting temperature.

摘要： A railcar bogie plate spring of the present invention includes: an upper surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in a longitudinal direction; a lower surface member constituted by fiber reinforced plastic in which reinforced fibers are stacked so as to extend in the longitudinal direction; and a core member arranged between the upper surface member and the lower surface member. The core member is constituted by fiber reinforced plastic in which: reinforced fibers are stacked in a width direction perpendicular to a stack direction of the upper surface member and the lower surface member; and in a side view of the core member, the reinforced fibers are inclined relative to a bending neutral axis so as to intersect with one another.
