Abstract: Shock absorber unit with polymeric convoluted compression spring having a variable spring rate is carried by the piston rod above the seal cover of the unit. The lower portion of the compression spring is formed with a series of mounting and stabilizing lips for the attachment of a dust tube encircling and protecting the upper portion of the piston rod. A rigid insert in the inner end of the compression spring prevents the polymeric material from flowing over the end of the shock absorber when the spring is under full compression loads and displacing the dust tube from its mounting.

Abstract: A hydraulic shock absorber for use on vehicles which includes a rubber attachment on the upper end thereof which is supported on the vehicle. A cap sealingly covers the rubber attachment to provide a sealed chamber communicating with oil in the cylinder of the shock absorber. A partition provided with a communicating hole is disposed in the chamber. A flexible membrane is disposed above the partition in the chamber and divides the chamber into sealed compartments. One of the sealed compartments is filled with pressurized gas, and the other sealed compartment is held in communication with the interior of the shock absorber. The arrangement of the invention provides a shock absorber with an improved secondary performance in dampening forces between the shock absorber and the body of the vehicle.

Abstract: A novel, vehicular suspension system comprising an air-bag shock absorbing assembly acting in cooperation with a plurality of sequentially deformable elastomeric members. The air-bag carries a portion of the load and at least some of the elastomeric members carry the remainder of the load. Each elastomeric member is supported in a retaining member so arranged that, as the load on the suspension system is increased, additional ones of the elastomeric members are sequentially compressed and absorb more of the load.

Abstract: The present invention discloses a multiple axle articulated suspension structure and system for vehicles wherein road and tire excitations of each axle are isolated from their opposing axle, as well as from the sprung mass. This is accomplished in a preferred embodiment of my invention via deflections in a combination integrally damped multiple spring means system including a pressure resistant air spring and a self-damping compressive resistant elastomer having high hysteresis characteristics, operatively providing a progressively increasing spring rate. The elastomer is disposed entirely within and functions in parallel with the air spring, such that the compressive resistance of the air spring supplements or augments that of the elastomer, and the high hysteresis of the elastomer serves to dampen fluctuations or deflective excitations induced in the air spring during what as known as jounce conditions.

Abstract: A rubber elastic engine mount with hydraulic damping, especially for motor vehicles, includes an elastic peripheral wall on the engine side joined with a metallic end wall that can be connected with an engine casing, and joined also with a metallic supporting element that can be connected to an engine supporting frame. The elastic wall together with the end walls forms a liquid-filled main chamber which is closed off by a partition connected with the supporting element, and which is connected with an auxiliary liquid-filled elastic walled chamber on the other side of the partition. The auxiliary chamber may be constructed generally the same as the main chamber, including an elastic peripheral wall joined with the supporting element and with a metallic end wall relatively away from the engine. The two end walls are rigidly connected. The peripheral walls function as thrust springs. The partition may be rigid and stationary, or it may be movable.

Abstract: The present invention relates to a suspension device for a rotating machine lacking balance, comprising at least one elastic support defining a first chamber filled with liquid, wherein said first chamber is connected to a second chamber, likewise filled with liquid, closed by a flexible wall subjected to alternate displacements of frequency and phase equal to the frequency of the lack of balance to be compensated.

Abstract: The present invention discloses a multiple axle articulated suspension structure and system for vehicles wherein road and tire excitations of each axle are isolated from their opposing axle, as well as from the sprung mass. This is accomplished via deflections of pressure-resistant spring means and load-equalizing supports. In preferred embodiments of this invention, both trailer and track versions of my novel vehicle suspension system are disclosed as having separately trunnioned rocker beam assemblies supported by cross axles, and wherein air and elastomeric spring means are combined in a number of combinations thereof. Air, elastomeric and hydraulic spring arrangements are contemplated, where the air spring is supplied with air at varying pressures which are a function of the load on the suspension, and wherein a height gauge located between the axle and the frame controls this pressure.

Abstract: A stress damper comprising a hydraulic accumulator having an expansible cavity filled with hydraulic fluid, a body of elastomer provided with at least one internal cavity filled with hydraulic fluid, and an intermediate element of elastomer provided between the accumulator and the elastomer body, having at least one duct providing communication between the cavities in the accumulator and the elastomer body and arranged so that a compressive stress applied to the accumulator will cause a reduction in the cross-section of the duct.

Abstract: A vehicle shock absorber of the hydraulic cylinder and piston type which includes a control valve for limiting pressure of the hydraulic fluid during compression movement to control the damping force of the device in accordance with rate of compression movement above a predetermined rate. The damping force is limited during expansion movement to provide good road-holding ability for the vehicle.

Abstract: A supplementary air spring unit suitable for user installation on a damper or shock absorber having a generally cylindrical body in which one bead end of a resilient tubular rolling-lobe boot is removably sealingly secured on the shock absorber body by a sleeve retained in place by the air pressure in the unit and in which the other beaded end of the boot is removably sealingly pinched between a master cap and an external shell, with the shell and bead being removably retained in position by a fastening means on the cap.

Abstract: A tire building drum for assembling and shaping green tire carcasses toroidal includes a central drum and side drums with membranes capable of being blown up to shape the tire carcass. Supporting rings are located on opposite sides of the central drum. The invention is characterized in that the core supporting ring consists of an elastomeric material with a high E-modulus and is provided on the inner side with a disk-shaped flange supported in a groove, the flange having concentric collapsible grooves and being capable of extending radially under air pressure.

Abstract: A drum for producing blanks for car tires of rubber with straps wherein the drum consists of coaxial rings movable axially relatively to each other and having supporting surfaces for the beads of tire blanks. According to the invention each ring has an annular groove containing a ring insert of an elastomeric material with a high E-modul. The insert is radially stretchable and consists of a cylindrical supporting part and a disk part firmly connected therewith. The disk part in cross-section has a toggle-like bend and is supported upon the base of the groove. The supporting part is fixed to a limiting flange.

Abstract: A cap member is fitted in a liquid-tight fashion to the open end of a cylinder. The cap member has a flexible member made of rubber etc. A piston rod connected to a piston within the cylinder is slidably inserted through the cap member. When an impact load is applied to the piston rod the piston rod and thus the piston are forced into the interior of the cylinder to cause an operational medium pressure to be increased to permit the flexible member to be resiliently deformed outward. As a result, a shock due to the impact load is absorbed.
