The present invention discloses the unique dampening and suspension spring characteristics of the multiple stage air shock. Each stage can be set up with a different dampening and suspension spring characteristic. The different dampening and suspension spring characteristic for each stage furnishes the multiple stage air shock with a plurality of dampening and suspension spring characteristics, thereby enabling the multiple stage air shock to respond to different road conditions and obstacles.

A gas spring end member is dimensioned for securement along an associated suspension member having an associated planar surface and at least an associated first side surface. The gas spring end member can include a base wall disposed transverse to a longitudinal axis and a bracket wall that extends longitudinally-outwardly from the base wall. The bracket wall can be adapted for operative connection to the associated suspension member such that the gas spring end member can be supported thereon with the base wall disposed in longitudinally spaced-apart relation to the associated planar surface of the associated suspension member. A gas spring assembly including such an end member can be included. A suspension system and a method of installation including such a gas spring assembly can also be included.

A vibration isolator includes a housing forming an internal cavity, an elastomeric diaphragm within the internal cavity, the elastomeric diaphragm combining with a first end of the housing to form an air spring within the internal cavity, a mechanical spring in series with the air spring within the internal cavity; a mount in series with the mechanical spring opposite the air spring, an annular elastomeric stopper between a second end of the housing and the mount, wherein the mount and the annular elastomeric stopper combine to seal the second end of the housing to form a chamber within the internal cavity between the elastomeric diaphragm and the second end of the housing, and a plate seated on the mount within the chamber.

In one embodiment, a gas spring having a travel control includes positive and negative chambers and a valve mechanism that controls the fluid communication between the chambers. The valve mechanism includes a valve bore that while only moving a small amount, allows for large changes in gas spring travel length.

A pump system may include a pump, a driveshaft, driving equipment, and a vibration dampening assembly configured to reduce pump-imposed high frequency/low amplitude and low frequency/high amplitude torsional vibrations. The pump may have an input shaft connected to the driveshaft. The driving equipment may include an output shaft having an output flange connected to the driveshaft. The driving equipment may be configured to rotate the driveshaft to rotate the input shaft of the pump therewith. The vibration dampening assembly may include one or more flywheels operably connected to the input shaft and configured to rotate therewith.

Disclosed herein is a process suitable for constructing the multiple stage air shock. The multiple stage air shock is unique among shocks in that the multiple stage design possesses qualities not available to other shock absorbers. The process includes a means for determining the compressed and extended lengths of the air shock based on the lengths of the parts for each stage. This means refers to one methodology and offers the air shock an extended length that is greater than twice its compressed length, an optimized extended length, and a construction capability based on adding stages. In particular, the extended length-compressed length relationship is a quality inherently unobtainable by current shock absorbers. The process also includes a means of determining the spring rate. This means refers to a second methodology and offers the capability to both set-up the air shock with a relatively linear spring rate and make the relatively linear spring rate more linear.

Systems and methods for reducing inertial forces of a reciprocating piston internal combustion engine are described. The systems and methods may provide for counterweights in a form of pistons in cylinders that are moved via electromagnets. The counterweights may be moved at a frequency that corresponds to engine speed via an alternating current.

A vibration absorber for securely fixing to the housing of a gearbox includes an absorber mass having a first group of segments that are rotationally symmetrical to one another with respect to a rotational axis and/or central axis of the gearbox. The segments can be rigidly connected to one another. The vibration absorber can further include connectors that are rigidly connected to two segments each.

An air spring assembly or air spring damper with an integrated valve control for controlling a level position of a vehicle or of a driver's cab includes a rolling tube, a lid and an air spring bellows which together delimit a pressure chamber with compressed air. A control valve includes an actuation device for feeding compressed air into the pressure chamber or for discharging compressed air from the pressure chamber. A compression spring device has a first end operatively connected to the rolling piston or the lid and a second end operatively connected to the actuation device. The compression spring device is configured with at least two parts including a central spring facing towards the rolling piston or the lid and a control valve biasing spring facing towards the control valve. The central spring is biased to a greater extent than the control valve biasing spring.
