Plastic bead reinforcement ring for fluid pressure devices

ABSTRACT OF THE DISCLOSURE Air springs or other fluid pressure devices have flexible elastomeric sleeves terminating in a pair of end beads which are clamped or crimped onto a pair of spaced end members. Each of the beads is reinforced by a solid annular ring of nonreinforced thermoplastic material which is molded within the sleeve beads. The rings preferably are formed of nylon and are sufficiently flexible to move with the end members and sleeve and return to their original shape after such movement. A similar nonreinforced plastic ring may be molded in a central portion of the elastomer sleeve to provide the girdle hoop of the sleeve.

Method for making airspring flex members

Abstract of the Disclosure METHOD FOR MAKING AIRSPRING FLEX MEMBERS A method of manufacturing a beadless flexible member for an airspring having a fully molded non-tubular shape. An axially segmented mold with tapered circular end bores is used with conically tapered end plugs which sealingly compress an uncured preform of the flexible member between the conical plugs and the tapered circular end bores. Compressed fluid is injected into the interior of the preform to radially expand it to the desired molded shape. At a rate determined by the radial expansion of the preform, the annular segments of the mold are axially moved together to accommodate the axial foreshortening of the preform during its radial expansion. After full axial closure of the mold, heat and pressure are applied to vulcanize the preform. The beadless, fully molded flexible member may be used for airsprings requiring zero pressure roll capability. Preferred forms of the flexible member have tapered wall thickness in the neck with circumferential indexing ribs for exact placement of compression rings on the finished airspring.

Clamp ring assembly for air spring

ABSTRACT OF THE DISCLOSURE An air spring formed by an axially spaced end member and a piston member with an intervening elastomeric flexible sleeve therebetween which forms a fluid pressure chamber. An annular clamp ring having a recess on the inner diameter thereof coacts with a corresponding annular projection on the outer diameter of the rigid piston member to positionally locate the ring on the piston member. A pair of clamping surfaces are located on opposite sides of the projection and are separated therefrom by expansion grooves. The projection and clamping surfaces form a series of pinch areas with the intervening sleeve, which sealingly clamp the sleeve therebetween. The expansion grooves receive portions of the sleeve and change the direction of reinforcing cords within the sleeve. Another radially extending groove traps a partially compressed end of the sleeve therein and provides an additional material expansion area. The clamp ring seats upon a shoulder of the piston member to reduce movement of the ring during operation of the air spring. The positioning of the ring proximate to the edge of the piston member provides a substantially continuous surface on which the sleeve rolls during operation of the air spring to reduce wear on the sleeve.

Air spring having internal sealing band and method of installing same

ABSTRACT OF THE DISCLOSURE An air spring for motor vehicles including first and second end members, at least one of which is a piston, with an intervening flexible sleeve forming a fluid pressure chamber therebetween sealingly connected to the end members. A continuous annular sealing band clamps at least one end of the flexible sleeve within an annular recess formed on the inside surface of an annular wall portion of one of the end members within an open end of the end member by compressing the sleeve material between the band and wall, and without deforming the band or wall of the end member beyond their elastic limits. In one embodiment, the annular wall of the end member is formed of plastic and is deformed outwardly but maintained within its elastic limits upon insertion of the band within the open end. The end of the sleeve is rolled over the sealing band and then the sleeve end and band are inserted by a press plate into the open end of the end member with the band compressing and sealing the flexible material of the sleeve into the annular recess. The compressed flexible material expands to seal the sleeve against the end member. In another embodiment, the press plate expands the plastic material of the end member outwardly upon inserting the band and a rolled end of the flexible sleeve into the annular recess of the annular wall portion whereupon the wall attempting to return to its unstressed state seals the flexible sleeve between the sidewall and band.

Pneumatic spring bellows

Clamp ring assembly for air spring

ABSTRACT OF THE DISCLOSURE An air spring formed by an axially spaced end member and a piston member with an intervening elastomeric flexible sleeve therebetween which forms a fluid pressure chamber. An annular clamp ring having a recess on the inner diameter thereof coacts with a corresponding annular projection on the outer diameter of the rigid piston member to positionally locate the ring on the piston member. A pair of clamping surfaces are located on opposite sides of the projection and are separated therefrom by expansion grooves. The projection and clamping surfaces form a series of pinch areas with the intervening sleeve, which sealingly clamp the sleeve therebetween. The expansion grooves receive portions of the sleeve and change the direction of reinforcing cords within the sleeve. Another radially extending groove traps a partially compressed end of the sleeve therein and provides an additional material expansion area. The clamp ring seats upon a shoulder of the piston member to reduce movement of the ring during operation of the air spring. The positioning of the ring proximate to the edge of the piston member provides a substantially continuous surface on which the sleeve rolls during operation of the air spring to reduce wear on the sleeve.

An air spring asembly, a moveable piston forit and method of attachment of flexible member to stamped steel piston

The air spring assembly is mounted between two surfaces, and comprises a flexible sleeve (12) and a movable hollow cylindrical piston (14), coaxially aligned about a common axis (22), connected by bead (32) and channel (42) fixing at respective ends to provide an air tight seal between the two parts which are closed at opposing ends by sealed end plates (16,18). The hollow piston which moves axially inside the flexible sleeve, according to pressure applied, provides an increased air reservoir capacity, dependant upon pressure applied. Annular tensile rings (29,33) located in the bead fixings allows the air spring to withstand tensile stresses during operation and eliminates the need to have a snap-on component to make a connection between the two parts.
