ELASTIC DEVICE FOR SUPPORTING A VEHICLE STRUCTURE ON A SUSPENSION STRUCTURE.

Ce dispositif de suspension se caractérise par une grande rigidité latérale dans la direction Y grâce à la masse d'élastomère 8, la rigidité en direction X étant notablement plus faible. Pour que la masse 8 soit soumise à une précontrainte de compression, la masse centrale d'élastomère 14, reprenant les efforts verticaux, fait saillie (ho) sur le plan de jonction P à l'état libre. Lors du serrage des pattes de fixation 4 sur la structure S, la masse 8 est ainsi mise en précontrainte de compression, du fait de l'inclinaison des parois 3 et 7 par rapport à l'axe vertical. This suspension device is characterized by great lateral rigidity in the Y direction thanks to the mass of elastomer 8, the rigidity in the X direction being notably lower. So that the mass 8 is subjected to a compressive prestressing, the central mass of elastomer 14, taking up the vertical forces, protrudes (ho) on the junction plane P in the free state. When tightening the fixing lugs 4 on the structure S, the mass 8 is thus put under compressive pre-stress, due to the inclination of the walls 3 and 7 relative to the vertical axis.

Variable flexibility spring of rubber or the like, more particularly for road, railway and tramway vehicles

667,689. Rubber springs. COOK, C. A. (Riv-Officine di Villar Perosa Soc. per Azioni). June 10, 1949, No. 15557/49. Class 108 (iii). In a spring of rubber or the like, comprising an inner rigid sleeve of conoidal shape, an outer rigid sleeve of conoidal shape and a rubber or the like sleeve forced and incapable of sliding between the rigid sleeves, the rubber sleeve is subjected under load to compression and rolling on the surfaces of the rigid sleeves, a disc being fixed to the inner rigid sleeve so as to exert on the rubber sleeve a predetermined pre-stressing and the disc being removed from the rubber sleeve when the load rises above the prestressing value. In the arrangement shown. in which a rubber sleeve 3 is radially compressed between substantially frustoconically shaped outer and inner members 1 and 2, the inner member is provided at one end with a load supporting disc 4 and at the other end with a shaped disc 5 which is adjustable on the member 1 to pre-stress the rubber sleeve 3. Deformation of the sleeve 3 under loads exceeding the pre-stressing value, increases until under extreme loads, the disc 4 comes into contact with the sleeve 3. Two or more supports acting in series or in parallel may be employed in a vehicle suspension.

ADJUSTABLE BUSH.

Elastomeric damping elements and applications for reducing shock and vibration

Shock and vibration eliminating elements are constructed of an elastomeric material, which is formed into shapes that have an elongated, generally trapezoidal cross-sectional area. Upper and lower mounting surfaces extend from the ends of the cross-sectional area. The upper and lower end mounting surfaces of the damping elements have integral, parallel surfaces that are used to mount the element to the two structures. The cross-sectional area of the damping elements locates the mounting surfaces so that a straight line normal to one of parallel mounting surfaces at one end of the cross-sectional area of a block, will not intersect the other mounting surface at the other end of the cross-sectional area. Thus, a force applied in a normal direction to one of the mounting surfaces will be translated into shear forces instead of comprehensive forces. This substantially increases the damping efficiency of the material for shock and vibrations, enabling it to eliminate forces that otherwise would be transmitted through the elastomeric body. A second damping material may be inserted into the interior of the elastomeric body to control the damping characteristics of the damping element.

Elastic suspension for the exhaust device of a motor vehicle

Elastic fastening element

Die Erfindung betrifft ein elastisches Befestigungselement mit stark unterschiedlichen Steifigkeiten in Längs-, Hoch- und Querrichtung mit Innenteil und Außenteil, zwischen denen Elastikpuffer eingespannt sind, wobei die einander gegenüberliegenden Stützflächen des Innenteils schräg zueinander verlaufen. Um das Befestigungselement auf einfache Weise mit einem rohrförmigen Element zu verbinden, ist das aufweitbare Innenteil innen mit einer Elastikschicht ausgekleidet, deren Innendurchmesser gleich ist dem Durchmesser des rohrförmigen Elementes und die eine Öffnung kleiner als 180° aufweist, so daß das Innenteil nach einer geringen Aufweitung radial auf das rohrförmige Element aufschiebbar und in Einbaulage durch die Elastikpuffer verspannt ist. The invention relates to an elastic fastening element with widely differing stiffnesses in the longitudinal, vertical and transverse directions with an inner part and an outer part, between which elastic buffers are clamped, the opposing support surfaces of the inner part running obliquely to one another. In order to connect the fastening element to a tubular element in a simple manner, the inside of the expandable inner part is lined with an elastic layer, the inner diameter of which is the same as the diameter of the tubular element and which has an opening smaller than 180 °, so that the inner part after a slight expansion can be pushed radially onto the tubular element and is braced in the installation position by the elastic buffer.

788,484. Resilient mountings. BOURGOIS, J. Jan. 20, 1956 [Jan. 22, 1955], No. 1980/56. Class 108(3) An elastic shock absorber or suspension device comprises two parts 19, 21, relatively movable and connected by means of a deformable block 3 having a cut-away portion 4 of flared or tapered configuration the lips 8; 9, of which, are made to approach one another and come into contact to an extent which increases with the load, and present a curvilinear profile which determines the spring rate of the device. In Fig. 9, the part 19 comprises two portions 19, 20 rigidly connected together and secured to opposite ends of the block 3. The part 21 comprises a stirrup connected to a middle portion 10 of the block 3. The cutaway portion 4 is engaged by two plates 13, 14, having curved end portions 15, 16, adapted to engage a circularly hollowed out portion 5 at the inner end of the cut-away portion 4. A lower screw 18 may be rotated to adjust the degree of pre-tension in the portion 10 of the block 3. An upper screw 18 may be adjusted to vary the abutment characteristics of the surfaces 13, 14 in relation to the lips 8, 9, of the block 4. In a modified construction (Figs. 7 and 8, not shown) the lower screw 18 is dispensed with and the plates 13, 14, are articulated adjacent the parts 15, 16. In a further modification the parts 19 and 20 constitute the relatively movable parts, the stirrup 21 being omitted.

The abutment 22 may alternatively be of cylindrical form. Lateral bulging of the material of the block 3 may be resisted by mounting washers on each end of a bolt passing ...

A cushioned mounting device

Vibration damper

Spring element

A spring element comprises metallic layers (2a-f) essentially transversal to the direction of compression between which resilient layers (3a-f) of elastic material are intercalated. The metallic layers (2a-f) and the elastic resilient layers (3a-f) are arranged one above the other in the direction of compression. When the spring element is compressed in the direction of compression, wedge-shaped friction bodies (5) in the spring element are pressed, at right angles to the direction of compression, against a friction surface (6) against which they rub. To obtain a compact, economical structure, the friction bodies (5) lie at least partially between two elastic resilient layers (3d, 3e). These two resilient layers (3d, 3e) and the other elastic resilient layers (3a, b, c, f) lie one above the other on a part of each friction body (5) and the metallic layers (2a-f) in the direction of compression (4).

Torque rod

A second inner member and a second insulator are provided in a second ring-shaped member forming a torque rod. A first bore section and a second bore section are provided in front of and in the rear of the second inner member. The insulator has an elastic arm section extending in the direction of a Y axis. A spring adjustment recess extends in a slit shape in the direction of an X axis from an end of the first bore section. The spring adjustment recess forms an unrestricted part of the elastic arm section by the second ring-shaped member, whereby the Z spring in the axial direction of the inner member is lowered, and the XZ spring ratio can be changed greatly while maintaining the size of the X spring in the main vibration inputting direction.
