  • Publication number: 20140319743
    Abstract: A dock bumper is provided. The dock bumper includes a housing holding a plurality of rollers arranged in an array. The plurality of rollers are arranged to absorb impact from a reversing vehicle. Upon impact, outer surfaces of the rollers are arranged to rotate relative to the frame. Consequently, scrubbing between the vehicle and dock bumper is reduced as are excess forces acting on fixings between the frame and wall. Also, a surface area at each contact location is increased as a cushioning effect is provided by rotation of the roller, thereby prolonging the operation life of the rollers. Furthermore, in one form, the dock bumper is modularised so that only worn or damaged rollers need be replaced at one time.

    Abstract: A wheel suspension system for a vehicle includes a mounting base and a striking base spaced from each other and moveable relative to each other along an arced line of motion. An insulator is coupled to and extends from the mounting base. The insulator is formed of an elastomeric material for compression between the mounting base and the striking base when the striking base contacts the insulator during movement of the mounting base and the striking base relative to each other. The insulator is compressed along the arced line of motion between the mounting base and the striking base. The insulator includes an impact portion extending at an acute angle relative to the base plane for distributing compressive forces within the insulator as the insulator is compressed along the arced line of motion. The distribution of the compressive forces within the insulator increases the durability and reliability of the insulator.

    Abstract: A spring is formed of a relatively thin sheet of spring material, which is constricted and held in place at each end forming a bell curve being located between two substantially planar members. As additional compressive force is applied in the vertical direction, the curve then compresses and starts to form sine waves. In an improved embodiment of the present invention, the sine wave spring is formed in a wedge shape, so that it is gradually taller and more progressive. This embodiment has been tested for use as a trailer spring with positive results. This wedge-shaped sine wave spring provides even more advantages over the Prior Art. The wedge-shaped prototype illustrates also how the present invention may be expanded to other shapes, in order to alter the spring characteristics, and also for packaging and other concerns.

  • Publication number: 20120073884
    Abstract: A spring is formed of a relatively thin sheet of spring material which is constricted and held in place at each end forming a bell curve being located between two substantially planar members. As additional compressive force is applied in the vertical direction, the curve then compresses and starts to form sine waves. The greater the force, progressively higher the wave frequency with lower amplitude would form. When the force is removed, the flexible material returns to its original shape. The force needed to shift the curve (increase the number of waveform) increases at an exponential rate, as opposed to the linear rate of most normal springs. The maintenance force of new stable state is considerable less than the threshold force. Such a relatively flat spring with an exponential spring rate and self dampening through phase change has a number of useful applications for automotive and industrial use.

The bumper includes a plurality of rebounding elements and a plurality of biasing elements, each that are fixed within one of the supporting frames of the housing. Each of the rebounding elements has a predetermined rebounding elements spring coefficient. The plurality of biasing elements has a biasing elements spring coefficient that is not equal to, and is preferably less than, the spring coefficient of each rebounding element. Further, each of the biasing elements abuts one of the rebounding elements. As such, as the interlocking supporting frames of the housing are compressed in a vehicle collision, the plurality of rebounding elements together with the plurality of biasing elements absorb the collision energy and are each compressed at different rates.

  • Patent number: 7458450
    Abstract: This invention is an impact energy absorption device, in which a long part (1) made of a high strength material is disposed with its lengthwise direction kept different from an impact direction, and both terminals of the long part (1) are connected with columns (2) through upper platens (3) covering the upper faces of the columns (2) kept standing apart from each other with a predetermined distance (L), comprising a structural system, in which a deformation of the long part (1) caused by the impact force applied to it, causes the upper platens (3) to move for compressing or deflecting the columns (2), thereby absorbing the impact energy. The conventional column type energy absorption member is weak against an impact applied in a direction within a wide angle (?) such as an impact applied in an oblique direction.

  • Patent number: 7441637
    Abstract: In a hydraulic shock absorber (1), a piston rod (5) protrudes from a cylinder (3) filled with hydraulic fluid. A rebound cushion (8) is fitted to an outer circumferential surface of the piston rod (5) in the cylinder (3). A stopper (6) fixed to the cylinder (3) contacts the rebound cushion (8) at an protrusion limiting position of the piston rod (5) to prevent further protrusion of the piston rod (5). An oil pool (8a, 9, 10, 15) formed in a sliding surface (8a, 14) of the rebound cushion (8) supplies oil to the sliding surface that slides on any of the inner circumferential surface of the cylinder (3) and the outer circumferential surface of the piston rod (5) to ensure smooth relative rotation of the piston rod (5) at the protrusion limiting position and the cylinder (3).

  • Publication number: 20080061484
    Abstract: A conventional solid protection device disposed on an exposed side of a cylinder for actuating a working device had a possibility of being permanently deformed by contacting an obstacle so as to be prevented from sliding properly corresponding to the telescopic movement of the hydraulic cylinder. An object of the invention is to provide a hardly deformable protection device. To protect an exposed side of a cylinder for a working device, a protection device 30 includes a guard member 32 and a slide guide 31 into which guard member 32 is telescopically fitted. Slide guide 31 is attached to a cylinder tube 9a, and a tip of guard member 32 is attached to a tip of piston rod 9b. Guard member 32 is a flat plate made of spring steel. A width of guard member 32 is larger than a diameter of the piston rod. Notches 32a are provided on lateral opposite sides of a basic side end of guard member 32. Sliders 33 are fitted to respective notches 32a.

  • Publication number: 20080012188
    Abstract: An insulator for a vehicle includes a first portion extending along an axis, an intermediate portion extending from the first portion along the axis, and a second portion extending from the intermediate portion along the axis. The first portion defines a first density and the second portion defines a second density different from the first density. Preferably, the first density is greater than the second density such that the second portion is more compressible than the first portion. The first portion, the intermediate portion, and the second portion are integrally formed of a common homogeneous microcellular polyurethane material for defining a one-piece insulator having different densities. In exemplary embodiments, the insulator is further defined as a jounce bumper or a coil spring isolator for disposition in a wheel suspension system, and a body insulator for disposition in a mount assembly of a vehicle.
