  • Patent number: 7364145
    Abstract: The present invention relates to the design and fabrication of flexures used to guide motion in mechanical systems. A high specific stiffness flexure includes two narrow and thin flexing sections separated by a longer stiffened section. The present invention provides designs and processes for making flexures and flexure systems with monolithic high specific stiffness frame or box structures for the stiffened sections that creates relatively higher self-resonant frequencies.

  • Publication number: 20080036125
    Abstract: In a central fastening element for an axially symmetric, vehicle gas spring, which includes a bellows that has central bores or cutouts in the region of its end faces, the fastening element being fixed to the vehicle body, protruding from the surroundings of the attachment point in a direction normal to it, and being encompassed by the bores or cutouts. The fastening element includes a shaped stud or a shaped cap, the maximum outer diameter of the stud or the cap being at least less than one fifth of the maximum outer diameter of the gas-spring bellows. A device may be provided which allows a gas spring to be installed in a simple manner and allows the spring bellows to rotate with respect to the suspension and/or the vehicle body during the initial installation and/or the initial operation.

  • Publication number: 20070194508
    Abstract: A compression spring is formed from an elongated tube by cutting slots at spaced intervals along the length of the tube, leaving only anchors of a small perimeteral extent connecting the beams formed by the remaining tube stock between each adjacent pair of slots. Adjacent slots are formed from diametrically opposed sides of the tube leaving one line of anchors on each side of the resultant spring.

  • Patent number: 7258541
    Abstract: An improved thermal expansion compensation manifold support is disclosed. The support includes a spring having a barrel and a skirt extending from the barrel, the skirt forming a recess. The spring has a first shoulder extending into the recess, and an end opposite the barrel. The support also includes a block having opposite ends, a finger portion formed at one end and a second shoulder formed at the opposite end. The finger has an end opposite the second shoulder, with the finger being dimensioned and configured to be inserted into the skirt's recess. The skirt and the block are dimensioned and configured such that when the finger is inserted into the recess, the skirt end abuts against the second shoulder and the finger end is separated from the first shoulder by a gap.

  • Patent number: 6655668
    Abstract: A device for the control of vibrations comprises a retainer resting on a base and a plurality of bearings disposed within the retainer. The bearings are arranged in a first layer and a second layer. The second layer is disposed on the first layer. The first layer comprises three or more bearings and the second layer comprising one or more bearings. Each bearing in the first layer is constrained on its bottom only by a substantially flat portion of the base, on its side by the retainer and is in contact with at least two adjacent bearings in the first layer. The bearings in the first layer support the bearing in the second layer. The retainer has a surface which is in substantially tangential contact with the bearings in the first layer.
