Abstract: The support has a generally annular shape and a fixing device extends axially therethrough. It comprises an annular elastically yieldable mass connected to two frames, a semi-toric membrane fixed between the two frames and defnining with the outer surface of the mass a work chamber (A). This chamber communicates with an expansion chamber (B) through a passageway. The support also includes a device for limiting its axial and radial movements. Such a support has a particularly low natural stiffness both in the radial direction and in the transverse direction, which improves the filtering of high frequency vibrations while affording a good damping of trepidations of low frequency and large amplitude.

Abstract: A fluid-damped elastomeric bushing of the invention comprises an inner sleeve and an outer sleeve in a concentric or eccentric relation, an elastric member provided between the inner and outer sleeve, a plurality of liquid chambers or compartments provided in the central portion of the elastic member with respect to the axial direction of the sleeve, the liquid compartments being arranged along the circumference at specified intervals, and orifices to communicate at least the adjacent liquid compartments with each other. The elastic compartment wall of the elastic member has a portion bent toward the interior of the liquid compartment. A central part of the elastic compartment wall may have its thickness reduced relative to the other part.

Abstract: A fluid-filled cylindrical elastic mount including an inner and an outer sleeve disposed in radially spaced-apart relation with each other and attached to one and the other of a load member and a support structure, an elastic body interposed between the inner and outer sleeves for elastically connecting these sleeves and having a pressure-receiving chamber, and a closure member cooperating with the outer sleeve to define a equilibrium chamber within a void formed between the inner and outer sleeves so as to extend in the axial direction of the sleeves. The pressure-receiving and equilibrium chambers are filled with a non-compressible fluid and communicate with each other through a restricted passage. A protective member fixedly provided on the inner sleeve for movement with the inner sleeve is inserted through the void so as to elastically deform the closure member toward the outer sleeve before the elastic mount is attached to the load member.

Abstract: A resilient bearing able to accommodate relative torsional movement between two concentric inner and outer tubular rigid members comprises between those members a resilient bearing having a layer of elastomeric material secured relative to one of the rigid members and a support member for sliding relative to the other rigid member. The support member is axially movable and preferably inclined relative to the axis of the bearing at its interface with the elastomeric material whereby any such axial movement results in compression loading of that elastomeric material.

Abstract: A bushing assembly for use in a suspension of an automotive vehicle. The bushing assembly is comprised of inner and outer cylinder members which are coaxial and spaced from each other. An elastic member and a rigid sleeve member are disposed between the inner and outer cylinder members. A sliding member is disposed between the inner cylinder member and the rigid sleeve member in order to reduce torsion spring effect of the elastic member. The sliding member is prevented from its axial displacement upon contacting with a radially outwardly extending retainer section formed in the inner cylinder member. Additionally, a generally cap-shaped seal rubber is provided to accomplish seal between the end section of the rigid sleeve member and the end section of the inner cylinder member.

Abstract: An improved deflection jounce bumper assembly for a vehicle suspension strut which dampens and limits the action of the shock absorber in its jounce stroke. The bumper assembly comprises an inverted metal cup-shaped shell member which attaches a molded elastomeric bumper member to the strut upper mount. The bumper member has a lower hollow right cylindrical sleeve portion which surrounds the strut piston rod with the sleeve upper end in turn surrounded by an outer side wall portion of the shell member. The sleeve portion has a predetermined height such that upon its lower end face impacting on the strut support casing upper end closure plate an initially high spring dampening rate is achieved. A control ring is embedded in the sleeve portion adjacent its lower end face which, together with the shell member outer side wall is operative to restrict and control the expansion of the sleeve portion as it undergoes progressive spring rate deformation adjacent the full jounce position.

Abstract: An improved deflection composite jounce bumper for a vehicle suspension strut. The bumper comprises an inverted metal cup-shaped shell insert embedded within a molded elastomeric body. The body defines a hollow elongated sleeve portion which surrounds a piston rod upper end with its upper portion in turn concentrically surrounded by the annular side wall of the shell. The sleeve portion has a predetermined height such that upon its lower end face impacting on the strut support casing upper end cap an initially high spring dampening rate is achieved. The shell outer side wall is operative to restrict the expansion of the sleeve portion as it undergoes progressive controlled deformation and compaction providing a substantially uniform spring rate while obviating over stressing of the jounce bumper.

Abstract: An engine mounting device resiliently supports an engine on a frame including a first plate member for connection to the frame. A second plate member is U-shaped and has flanges at each end of the U-shaped portion for connection to the first plate member and the frame. A tubular member is disposed between and spaced from the first plate member and the second plate member. A resilient member interconnects the tubular member and the first and second plate members for resiliently supporting the tubular member between the first and second plate members. The first plate member includes a plurality of raised ribs laterally spaced one from the other and forms an arch-shaped opening for receiving a first end of the resilient member to prevent lateral movement of the resilient member. The resilient member has a second end arcuate and complimentary to the U-shaped portion of the second plate member to prevent lateral and radial movement of the resilient member.

Abstract: An elastic bushing assembly including a rigid sleeve member disposed radially inwardly of an outer sleeve, the sleeve member having a radial flange extending radially outwardly from one axial end thereof, an elastic member interposed between the outer sleeve and the sleeve member, an inner sleeve disposed radially inwardly of the sleeve member, a sliding member interposed between the inner sleeve and the sleeve member and slidable relative to one of the inner sleeve and the sleeve member. A retainer member is located at one axial end of the inner sleeve corresponding to the radial flange of the sleeve member, and a sealing rubber member is in pressed abutting contact with the radial flange of the sleeve member and the retainer member, so as to provide sealing therebetween. The rubber member includes two radially spaced-apart annular sealing lips whose diameters increase in an axially outward direction of the sleeve member away from the radial flange.

Abstract: A suspension rubber bushing pivot installation for automobiles and the like incorporates an upsetting washer and expedients associated therewith in the bushing proper which coact under tightening of a fastener bolt to enhance the rattle-free frictional engagement of the latter with its supporting chassis bracket.

Abstract: A method and buffer apparatus for preventing corrosion in a dynamic load bearing assembly. A resilient buffer material is compressively adjustably positioned between a pair of dynamic adjacent load bearing components in a machine such that the amount of electrical resistance between the load bearing components can be varied without having to disassemble the machine. The buffer material is maintained in position between the load bearing components by compressing the buffer material an amount equal to 5 to 30% of its length to outwardly expand surfaces of the buffer material against the load bearing members.

Abstract: An improved automotive suspension strut isolator and jounce bumper upper mount providing a compact resilient assembly adaptable for a vehicle having a reduced hood line. The assembly comprises a collar member formed with an upstanding collar portion having a radially outwardly extending contact flange. An inverted cylindrical cup member is positioned in spaced relation with the collar separated by an elastomeric isolator. The cup member includes a return bend flange underlying the contact flange in an axially spaced manner. The cup member is sized to telescopically accommodate the upper end of the strut outer support casing at full jounce travel thereby lowering the overall strut height for a given vehicle attachment span. In one form of the invention the strut utilizes a convoluted dust shield as a jounce bumper.

Abstract: Axially and radially-loadable bearing which damps in an axial direction for elastic mounting of machines, machine parts, and/or vehicle parts. This bearing has an outer part and two elastomeric or rubber springs located between an inner, often rotating, part and an outer part, which form a cavity area which is preferably filled with damping fluid and in which there is a partition separating the cavity into two chambers. The partition comprises a rigid sliding part guided on the inner part and a rigid fastening part connected in a fixed manner to the outer part. The two rigid parts are connected to one another by means of an elastomeric or rubber thrust washer. Preferably, there is a throttle in at least one of the rigid parts.

Abstract: A spring system for resiliently supporting a mass with respect to a base comprises a supporting member mounted for movement and which can be coupled to the mass and is bounded by a portion of a spherical surface which bears against a concentric complementary guiding spherical surface fixed with respect to the base to guide the supporting member to rotate in all directions around the center of the sphere. A circular resilient device is provided in engagement with the supporting member and is supported with respect to the base. The supporting member is coupled to the mass at a point inside the circular resilient device whereby the supporting member is tilted by radial shocks while its spherical surface is guided along the guiding spherical surface and by the deformations of the resilient device as a result thereof, a resilient couple and/or a radial resilient force is developed which tends to move the supporting member into its initial position.

Abstract: A suspension system has at least one swing member for pivotally connecting one of wheels of the motor vehicle to a body of the vehicle. The swing member is rotatably supported on a shaft through an annular rubber bush secured to the shaft. The annular rubber bush has spring constants which are different in value at angular positions. Accordingly, by rotating the shaft, the spring constants with respect to the swing member are changed.
