A carcass stabilization system for a meat processing plant having carcasses transported along a processing line is provided. The system includes a stabilizer installed proximate the processing line and having a carcass engagement component and a shock absorbing device coupled to the carcass engagement component adapted to absorb at least some of the forces resulting from the carcasses impacting the carcass engagement component. The system also includes a stabilizing surface extending along the processing line opposite the stabilizer such that the carcasses are transported along the processing line between the stabilizing surface and the stabilizer, where the carcass engagement component is adapted to engage and bias the carcasses against the stabilizing surface.

First end member section includes a first outer peripheral wall portion. Second end member section includes a second outer peripheral wall portion. Second end member section is positioned in abutting engagement with the first end member section such that a groove extends peripherally around first and second end member sections between first and second outer peripheral wall portions. Third end member section is injection molded in situ with first and second end member sections such that third end member section extends peripherally around first and second end member sections within groove. Gas spring assemblies and vehicle suspension systems are also included.

A combination gas spring and shock absorber apparatus includes a vented gas spring housing and a vented shock absorber housing slidably mounted within the gas spring housing. A shock absorber piston is concentrically mounted within a gas spring piston. A base housing is slidably mounted in the gas spring housing. A shaft extends through the base housing and into the shock absorber housing. The shock absorber piston is mounted in the shock absorber housing on the free end of the shaft. The gas spring piston is mounted in the gas spring housing on the distal end of the base housing. The shock absorber piston is fluidically sealed and slides within the shock absorber housing. The gas spring piston is fluidically sealed and slides along the gas spring housing and the shock absorber housing. The base housing telescopically translates relative to the gas spring housing.

A gas spring comprising: a cup-shaped body; a movable piston which is inserted in an axially slidable manner in the cup-shaped body and is coupled to the cup-shaped body in a fluid-tight manner, so as to delimit a variable-volume closed chamber adapted to contain a pressurised gas; and a safety plug provided with a shank which extends in pass-through manner in the bottom wall of the cup-shaped body, and protrudes cantilevered within the cup-shaped body so that its distal end can be reached/struck by the movable piston in the case of overtravel; the distal end of the shank having a substantially tubular structure that directly communicates with the closed chamber.

An end member assembly can include a first end member section and a second end member section that together form an end member volume. A partition section is provided separately and is disposed within the end member volume to separate the end member volume into at least two volume portions. At least one passage extends through the partition section and at least one control device is disposed in fluid communication along the passage. The control device substantially fluidically isolates the two volume portions under conditions of use below a predetermined differential pressure threshold. The control device permits fluid communication between the two volume portions under conditions of use in which the predetermined pressure threshold is exceeded. Gas spring assemblies including such an end member assembly as well as suspension systems and methods of manufacture are also included.

A gas pressure spring is provided including a working cylinder which, together with a slidably mounted compensating piston, encloses a working chamber filled with a working medium. A slidably mounted working piston is fastened to a working rod. In the event of a temperature increase, a compensating medium in a compensating chamber expands. The compensating piston is acted upon by the pressure of the working medium and the pressure of the compensating medium) such that the volume of the working chamber is increased. The temperature dependency of the gas spring force should be reduced by a design which is as simple as possible. For this purpose, the compensating chamber is at least partially surrounded by the working rod. Thus, the compensating medium can be compactly accommodated, and the assembly of the gas spring is simplified.

The present invention relates to a spring unit (1) for a shock absorber (100) intended for a vehicle. The shock absorber (100) comprises a damping cylinder (101), wherein the damping cylinder (101) is adapted to be telescopically arranged within the spring unit (1). The spring unit (1) comprises a hollow body (2) comprising at least one compression chamber (2b) and at least one additional chamber (3) arranged to be in fluid communication with the compression chamber such that at least a first flow of fluid (F1) is adapted to be allowed between the compression chamber (2b) and the additional chamber (3) when a threshold value is met. The invention further relates to a shock absorber (100) comprising such a spring unit (1), and a front fork comprising such a shock absorber (100) as well as a method for filling the shock absorber (100).

Shock absorption assemblies are provided. A shock absorption assembly includes an air shock that has a valve body. An air spring tube defines an air spring chamber. A piston rod extends through the air spring chamber to an oil piston head. An air piston head movably coupled to the piston rod. An oil damper tube is coupled to the piston head and is movable relative to the piston rod and the air spring tube. The shock absorption assembly further includes a mechanical spring disposed radially outward from, and that annularly surrounds, at least a portion of the air shock.

A pressure-balanced shock absorber has an outer tube, an inflatable base, a piston tube, a valve adjusting rod, a piston base, an inner tube, and an adjusting resilient element. The inflatable base has a valve passage and a first valve core. The first valve core selectively seals the valve passage. The piston tube communicates with the valve passage. The valve adjusting rod is movably mounted in the valve passage of the inflatable base and the valve tube. The piston base is connected to the piston tube and has a piston passage. A second valve core selectively seals the piston passage. The inner tube is mounted around the piston tube. The piston base divides the inner tube into a first air chamber and a second air chamber. The adjusting resilient element is disposed in the piston tube to achieve the effect of inflating two air chambers.

A multi-dimensional magnetic negative-stiffness mechanism and a multi-dimensional magnetic negative-stiffness vibration isolation system composed thereof are provided. The multi-dimensional damping system is composed of a positive-stiffness mechanism, a multi-dimensional negative-stiffness mechanism, a floating frame, a vibration isolated body, and a mounting base. The positive-stiffness mechanism is a traditional elastic element connected to the vibration isolated body and the mounting base, and provides supporting forces in an X direction, a Y direction, and a Z direction, and a basic vibration isolation function. The multi-dimensional negative-stiffness mechanism is composed of at least two negative-stiffness magnetic groups. Each negative-stiffness magnetic group may provide one-dimensional or two-dimensional negative stiffness. Through a series connection of the at least two negative-stiffness magnetic groups, a two-dimensional or three-dimensional negative-stiffness effect may be implemented to improve the vibration isolation performance of the system in multiple dimensions.
