摘要:
A compression spring useful in vehicle suspension applications comprises reinforced elastomer elements combined in series and/or in parallel and having differences in size and/or shape and/or material properties so as to achieve non-linear force:deflection characteristics which can be tailored to specific applications. In one "serially-coupled" embodiment the spring is constructed as an assembly of tubular frustoconical elastomer bodies provided with annular reinforcing rings bonded to their axially spaced-apart end faces, and in another "parallel-coupled" embodiment the spring is constructed as an annular-sectioned frustoconical elastomer body having within the internal cavity thereof a further elastomer body, of cylindrical form for example, arranged to be compressed only after the frustoconical body has been compressed to a predetermined extent. The parallel-coupled embodiment can also be used in a serially-coupled mode with one or more embodiments of its own kind and/or of the firstmentioned kind. Fluid damping and active suspension arrangements are also disclosed, such arrangements taking advantage of the voids defined within the elastomer bodies.
摘要:
A resilient mounting intended primarily to withstand compressive loading is of a tubular and interleaved construction (10) comprising a pair of end plates (11,12) and an intermediate annular plate (19) which serves to stiffen a tubular elastomeric body (13) provided between the end plates. A buffer member (23) is secured to one (11) of the end plates (11,12) and extends longitudinally within the tubular body (13) to lie normally free from contact with the tubular body. A protective cushioning layer (20) provided between the buffer member (23) and internal edge of the intermediate plate (19) prevents direct contact between the buffer member and intermediate plate under transverse load.
摘要:
A mounting bracket assembly (12) particularly suited for installation in an aircraft having outboard turbine engines (E) to isolate the aircraft cabin from engine noises. The bracket assembly (12) includes a base (13) fastened below the wing pylon and a pair of arms (20,21) extending in spaced parallel relation below the base. The forward ends of the arms (20,21) are connected to the engine (E), and the aft ends are interconnected by a torque tube (22) which is resiliently fastened to the mounting bracket base (13) by an elastomeric bearing assembly (26). The elastomeric bearing assembly (26) includes a series of laminations of elastic (27,29,31) and inelastic (28,30) layers which extend along diametrically opposite upper and lower sides of the torque tube (22) to mount the arms (20,21) in resilient cantilever fashion to the base (13). The elastomeric bearing assembly (26) permits the arms (20,21) to rock about a pivot axis (A) through the torque tube (22) while accommodating other motions of the arms, such as vertical translations and relative angular displacements imposed under certain engine operating conditions.

Dispositif actif permettant de faire varier la raideur d'éléments de suspension, notamment pour véhicules automobiles. Un élément à mémoire (3, 11, 20, 33, 43) est noyé dans la zone d'élastomère dont on veut faire varier la raideur. Application aux éléments de suspension.
摘要:
Das aus einem Elastomerblock gefertigte bewehrte Auflager ist dadurch schubversteift, daß in mindestens einen im Elastomerblock (1) ausgebildeten Hohlraum (6) ein biegefester oder biegesteifer Kern (14) eingreift, der biegefest mit einer Bewehrungsplatte (4) ("Lagerplatte") verbunden ist, die ihrerseits praktisch vollständig vom Elastomer des Elastomerblocks 1 umschlossen und in diesem Elastomer einvulkanisiert ist.
摘要:
@ A sound isolating bearing has concentric inner and outer housings made of steel with a concentric shim between the inner and outer housings sandwiched by layers of a resilient elastomer. The longitudinal cross section of the shim is convex on both inside and outside surfaces with the same radius of curvature to allow cocking of the inner housing relative to the outer housing about a first point on the bearing axis midway between the ends and about a second pivot point outside the bearing in a plane midway between the bearing ends perpendicular to the bearing axis.

A vibration isolation device (10) includes a first mounting member (11) connected to one of a vibration generating portion and a vibration receiving portion, and a second mounting member (12) connected to the other; an elastic body (13) disposed between the mounting members (11, 12); a first stopper elastic body (27) having a first stopper surface (26) which is disposed on either one of opposing surfaces (24, 25) that oppose each other, respectively on the first mounting member (11) and the second mounting member (12), and which faces the other surface such as to be capable of coming into contact therewith; and a second stopper elastic body (29) having a second stopper surface (28) which is disposed on either one of the opposing surfaces (24, 25), respectively on the first mounting member (11) and the second mounting member (12), and which faces the other surface such as to be capable of coming into contact therewith. The distance between the first stopper surface (26) and the opposing surface (24) facing the first stopper surface (26) is smaller than the distance between the second stopper surface (28) and the opposing surface (24) facing the second stopper surface (28).
