Abstract: A bumper spring assembly having a one piece mandrel including an integral head piece is further configured with a cage assembly retained on the mandrel with a cage nut locked to the mandrel to obviate the need for pins, set screws, and the like, to provide a more robust assembly. In two embodiments the cage nut is locked to the mandrel in a swaging operation. Improved flow of fluids through and around the bumper spring assembly are also provided.

Abstract: Springs of different types are provided with the ability to dynamically change stiffness. A number of embodiments feature hollow tubing wherein stiffness change is accomplished due to the pressure change inside the tubing which affects the stresses in tubing walls. In other embodiments inside pressure change causes variability in tubing's cross-section shape and size leading to large changes in stiffness. A number of embodiments feature spring coil diameter variability achieved by a variety of means and resulting in highly substantial changes in stiffness and for some embodiments spring length variability thus providing them with actuation capability in addition to stiffness variability.

Abstract: A system for reducing the effect of a force includes a panel having a first side and a second side; a plurality of contact members disposed around a perimeter of the panel first side; and a biasing member positioned around a perimeter of the panel second side. The perimeter of the panel second side generally corresponds to the perimeter of the panel first side. The biasing member biases the contact members toward the panel first side. In a use configuration, a force received by the panel second side is at least partially transferred to the contact members causing at least one of the contact members to temporarily lose contact with the panel first side, whereby the return of the contact member into contact with the panel first side imparts a second force onto the panel first side, the second force being less than the force transferred to the contact members.

Abstract: A coil spring modeling apparatus includes a first attachment member disposed on a lower spring seat, a second attachment member disposed on an upper spring seat, an actuator unit formed of a Stewart-platform-type parallel mechanism, a hydraulic pressure supply device, a torsion detection mechanism, and a controller. The torsion detection mechanism is constituted of displacement gauges such as a linear variable differential transformer. The displacement gauges are provided on hydraulic cylinders, and detect amounts of displacement relative to the reference lengths of the hydraulic cylinders, respectively. The controller calculates a relative torsional angle between the first attachment member and the second attachment member based on the detected displacement.

Abstract: A suspension coil spring, when assembled to a suspension device, in which a spring reaction axis (AR) is positioned coincident with or sufficiently close to a load input axis (AA), and the design and manufacture of coil springs are facilitated. Namely, 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) and the distance from the end turn center (CU) of the upper seating surface (38) to an imaginary coil axis (AI) is an upper inclination amount (VU), and the distance from the end turn center (CL) to the imaginary coil axis (AI) is a lower inclination amount (VL). When the suspension coil spring (10) is interposed between spring seats (22, 24) in the suspension device and compressed along a strut axis, the spring reaction AR axis of the suspension coil spring (10) is inclined and offset with respect to the imaginary coil axis (AL) according to the inclination amounts (VU, VL).
