Abstract:
End member assemblies that are dimensioned for use in forming a gas spring assembly can include an end member core that is dimensioned for securement to a flexible spring member to at least partially form the gas spring assembly. The end member assemblies can also include a plurality of rib members that are supported on the core body. The plurality of rib members are disposed in spaced relation relative to one another and include an end disposed radially outward beyond the core body. A skirt body can be supported on the core body in operative engagement with the plurality of rib members. The skirt body can include at least one surface operative to engage the flexible spring member. Gas spring assemblies, suspension systems and methods are also included.
Abstract:
A refrigerant analyzer (10) including a sample chamber (12) including, a proximal end (14), a distal end (16), an inlet port (18) and an outlet port (20), an infrared lamp (22) disposed adjacent to the proximal end (14) of the sample chamber (12), an optical filter (24) disposed adjacent to the distal end (16) of the sample chamber (12), and a non-dispersive infrared sensor (26) disposed adjacent to the optical filter (24); wherein the optical filter (24) is configured to transmit a wavelength less than or equal to approximately 15,500 nanometers. A method of detecting a counterfeit refrigerant within a system utilizing a refrigerant analyzer (10), the method including the steps: (a) connecting a refrigerant container (52) to the refrigerant analyzer, (b) operating the infrared lamp (22) and the non-dispersive infrared sensor (26) for a duration of time, and c) operating the non-dispersive infrared sensor (26) to detect a wavelength less than or equal to approximately 15,500 nanometers.
Abstract:
Die Erfindung betrifft eine Luftfeder (1) mit einem Deckel (4), einem Bodenelement (6) und mit einem dazwischen druckdicht eingespannten flexiblen Balg (8) sowie mit einer zumindest teilweise in den Balg (8) integrierten Niveaumesseinrichtung (10) zum Erfassen des Höhenniveaus der Luftfeder (1). Die Erfindung sieht vor, dass die Niveaumesseinrichtung (10) wenigstens Folgendes aufweist: a) Wenigstens einen in den Balg (8) integrierten, mit dem Deckel (4) oder mit dem Bodenelement (6) zumindest drehfest verbundenen Winkelsensor (12), welcher ein in Bezug zu einer Basis (16) drehbares Element (14) aufweist, b) eine einerseits mit dem drehbaren Element (14) des Winkelsensors (12) und andererseits mit dem Deckel (4) oder mit dem Kolben (6) verbundene mechanische Koppelung (30, 30', 30", 30'", 30""), derart, dass mit einer Änderung des Höhenniveaus der Luftfeder (1) ein Winkel (ω) wenigstens eines Elements (30; 30a'; 30a"; 30a'"; 30a"") der mechanischen Koppelung (30, 30', 30", 30'", 30"") verändert wird und der Winkelsensor (12) ein von der Winkeländerung des Elements (30; 30a'; 30a"; 30a'"; 30a"") abhängiges Winkelsignal erzeugt, c) eine Auswerteeinrichtung (18), durch welche das vom Winkelsensor (12) stammende Winkelsignal einem Höhenniveau der Luftfeder (1) zugeordnet wird.
Abstract:
Luftfederungseinrichtung für ein Schienenfahrzeug, umfassend eine Luftfeder (1), wobei das in der Luftfeder (1) umfasste Gasvolumen (2) über eine Leitung (3) mit einem Regelvolumen (5) eines Regelvolumenbehälter (4) verbunden ist, wobei das Regelvolumen (5) mittels einer kraftunterstützten Betätigungseinrichtung in seinem Rauminhalt veränderbar ist.
Abstract:
End members (204) for a gas spring assembly (200) include an end member body (226) that is formed from a polymeric material. The end member body (226) includes an end wall (234) and a bumper mount (258) that is integrally formed with at least the end wall (234) from the polymeric material of the end member body (226). The bumper mount (258) projects axially from the end wall (234) in a first direction. The end member (204) includes a central support post (256) that extends from the end wall (234) in a direction opposite the bumper mount (258). The end member (204) also includes an insert (272) that is at least partially embedded within at least one of the bumper mount (258) and the central support post wall (256). Gas spring assemblies and suspension systems are also included.
Abstract:
A gas spring and component assembly includes a flexible wall and an end member secured across an end of the flexible wall. The end member can include an end member wall with a first surface disposed toward the flexible wall and a second surface facing away from the flexible wall. A component can be secured along the end member and can include a component wall with a first surface disposed along one of the first surface and the second surface of the end member. An embedded fastener connection can be formed between the end member and the component and can secure the end member and the component in fixed relation to one another. Methods of assembling a gas spring assembly and methods of assembling a suspension system are also included.
Abstract:
An air spring (10) comprises a hollow elastic sleeve (12), an upper component (22) for securing the air spring to a first frame, a hollow piston (14) for securing the air spring (10) to a second frame that is movable relative to the first frame, and a cylinder (16) surrounding the hollow elastic sleeve to constrain the diameter of the hollow sleeve (12) and reduce the effective area of the air spring to reduce the natural frequency of the air spring (10).
