Abstract: In a shock strut for a vehicle including a spring plate for supporting a helical spring, a receiving or catching member is connected to the spring plate. The receiving member prevents any lateral movement of the helical spring in the event of a spring failure. A simple connection of the receiving member to the spring plate is provided independently of the materials used for these members. The connection is afforded by downwardly projecting parts on the receiving member which extend through suitably dimensioned openings in the spring plate.

Abstract: In a shock absorber unit for vehicles of the double-tube type a piston rod guiding member is provided at respective first ends of a cylinder and a container surrounding the cylinder. The first end of the container engagingly surrounds a radially outer face of the piston rod guide member. The container is tube-shaped and has substantially constant wall thickness along its total length. The radially outer surface of the piston rod guiding member is provided with at least one radially inward directed recess or at least one radially outward directed projection. The first end of the container is deformed such as to engage this projection or recess respectively. A sleeve member engagingly surrounds the first end of the container. This sleeve member is also provided with a deformation which deformation is in engagement with the deformation of the container.

Abstract: An improved hydro-pneumatic damping unit includes a cylinder member, a piston rod extending through a central cavity in the cylinder member and within a guiding bore of a guiding and sealing unit at one end of the cylinder member, and a cylindrical container coaxially surrounding the cylinder member. The guiding and sealing unit includes a guiding member housed inside an axial section of the cylindrical container, and a bridging arrangement is arranged to center the guiding member relative to the container. At least the part of the guiding member which is housed inside the axial section of the container has an outer diameter which is smaller than the inner diameter of the container section. Also, the bridging arrangement includes an annular centering member between the container and the guiding member for radially centering the guiding member relative to the container, and an annular sealing member cooperative with the annular centering member seals the annular cavity in the axial direction of the container.

Abstract: In a cylinder piston device, a piston unit is fixed to a piston rod member within a cavity defined by a cylinder member. The piston unit is provided with a piston ring supporting face, which is directed substantially in a radially outward direction towards the inner circumferential surface of the cylinder member. A piston ring member with a radially inner circumferential face and a radially outer circumferential face is supported by its radially inner circumferential face on said piston ring supporting face and engages by its radially outer circumferential face the inner circumferential surface of the cylinder member. The piston ring member is provided with at least one radially inward directed projection extending in the radially inward direction beyond the radially inner circumferential face, the projection axially engaging a securing face of the piston unit, and the securing face extending radially inward of the piston ring supporting face.

Abstract: A shackle assembly for fastening of compression struts at the steering knuckle in the wheel suspension of a motor vehicle is formed with an inner and an outer strap member, the straps being adapted to be arranged together to define a compression strut span within which a compression strut may be received. Holes are formed in both the inner and outer strap member through which fastening screws are received. The holes are defined through the strap members at a location outside of the compression strut span with the holes extending through the inner strap member being formed with a larger diameter than the holes defined through the outer strap member.

Abstract: A piston-cylinder unit including a cylinder assembly, a guide and seal assembly at one end of the cylinder assembly and a piston rod assembly axially movable relative to said cylinder assembly through the guide and seal assembly is formed with a cap assembly having an annular bottom, which is essentially normal to the axis of the unit, and a jacket with the piston rod assembly extending through the annular bottom and with the annular bottom being located adjacent the guide and seal assembly on a side thereof facing away from a hollow space defined within the cylinder assembly. The jacket bears against the outer circumferential surface of the cylinder assembly, and a tubular body which is elastically compressible in the axial direction is arranged on the outer portion of the piston rod assembly, with the tubular body being fastened in the axial direction on a fastening point of the piston rod assembly at a portion facing away from the cap assembly.

Abstract: A fluid damped unit includes a cylinder, a piston rod arranged for extending and retracting movement from one end of the cylinder, the rod having a piston at its end within the cylinder, and a damper unit arranged in an annular work chamber formed between the piston rod and the cylinder for damping the movement of the piston rod. The damper unit includes a damping ring which is carried in a damping ring carrier, the ring frictionally contacting the inner circumferential surface of the cylinder. A stop ring is mounted to the piston rod for contacting the damping ring carrier when the piston rod is extended past a predetermind intermediate position toward a fully extended position wherein movement of the piston rod is hydraulically damped. The damping ring carrier is arranged to be fixed in the axial direction of the cylinder when the piston rod is retracted beyond its predetermined intermediate position.

Abstract: A fluidic damping mechanism including a cylinder, a piston rod and a piston dividing the interior of the cylinder into a pair of working chambers is arranged to include within one of the working chambers a composite damping structure which imparts damping characteristics derived from the combined action of a mechanical spring mechanism and fluid throttling components.

Abstract: A shock absorber assembly including a cylinder having a piston and piston rod mechanism movable relative thereto is formed with a hydraulic-mechanical damping system interposed in an annular space defined between the piston rod and the cylinder. The damping characteristics of the system are varied in accordance with the relative movement of the piston rod out of the cylinder by a damping mechanism which includes a spring, an annular member and a damping component operating to vary the cross-sectional area of the damping passage defined therethrough.

Abstract: A hydro-pneumatic damping device particularly for spring legs of automotive vehicles comprises an inner cylinder, an outer container, a central cavity within the inner cylinder, an annular cavity between the inner cylinder and the outer container, a piston rod with a piston unit, venting passage means between the central cavity and the annular cavity extending across a cylinder closing unit and check valve means associated to said venting passage means. The check valve means comprise an annular check valve member in frictional sliding engagement with the piston rod for axial movement with the piston rod toward a sealing position during inward movement of the piston rod and toward an opening position during outward movement of the piston rod, first and second abutment means being provided for defining said sealing position and said opening position of said annular check valve member respectively.

Abstract: In a vibration damper or shock absorber for a vehicle, an axially extending cylinder is positioned within a similarly axially extending container with an annular reservoir formed between them. A piston rod extends through a guide in one end of the cylinder and includes a piston axially slidable within the cylinder for dividing it into a pair of working spaces interconnected through a damping device in the piston. One of the working spaces is in fluid connection with the reservoir. A connection is provided between the piston rod guide and the container and includes an annular groove in the guide and a projection from the container extending into the groove. Further, a sealing ring is provided between the guide and the container axially outwardly from the projection-groove. A certain amount of axial play is afforded between the container and the piston rod guide.
