20080228352 | VEHICLE SUSPENSION SYSTEM AND METHOD OF OPERATING SAME - A suspension system for use on a vehicle having two or more rear axles. The suspension system includes a plurality of gas springs and plurality of height sensors capable of outputting signals having a relation to distances between the respective ends of the respective first and second rear axles and the sprung mass of the vehicle. A control system adapted to selectively inflate or deflate respective ones of the plurality of gas springs to thereby adjust a leveled orientation of the sprung mass. The control system includes a controller that is adapted to determine a rear axle vertical offset and a rear axle articulation offset. The controller is adapted to determine whether conditions are appropriate for adjusting the suspension system by comparing the rear axle vertical offset and/or the rear axle articulation offset to a corresponding vertical offset threshold and/or an articulation offset threshold. A method is also included. | 09-18-2008 |
20080290617 | Gas suspension system and method - A method of operating a gas suspension system includes generating a first quantity of gas having a storage pressure and transferring the first quantity of gas into the pressurized gas storage device such that a second quantity of gas having approximately the storage pressure remains in a transfer pathway. The method also includes determining that a condition exists for venting gas from the gas spring assembly and placing the second quantity of gas into fluid communication with a quantity of gas having said spring pressure. The method further includes waiting until an approximately equilibrium pressure has been reached, and then actuating a third control device to exhaust at least a portion of the gas from the suspension system. A gas suspension system adapted to perform the method is also included. | 11-27-2008 |
20100030425 | METHOD AND SYSTEM FOR ALIGNING A VEHICLE WITH AN ARTIFICIAL HORIZON - A method and system for positioning a vehicle chassis in approximate alignment with a predetermined datum are provided. The vehicle includes a first longitudinal end adapted to be pivotally connected to a substantially fixed point and a second longitudinal end including at least one axle and an operatively associated two-corner fluid suspension system. According to the method, the fluid suspension system controls the alignment of the vehicle chassis to be aligned with an artificial horizon represented as the predetermined datum. | 02-04-2010 |
20110093239 | VEHICLE WEIGHT SENSING METHODS AND SYSTEMS - Disclosed are vehicle weight sensing methods and systems. According to one aspect of this disclosure, provided is a method of characterizing a vehicle to determine gross axle weights by accessing a computer readable database which correlates a plurality of pressures associated with fluid suspension members incorporated into the vehicle. | 04-21-2011 |
20110115140 | GAS SPRING AND GAS DAMPER ASSEMBLY AND METHOD - A gas spring and gas damper assembly includes a first end member, a second end member and a flexible wall that at least partially defines a first spring chamber therebetween. A damping chamber wall at least partially defines a damping chamber. A damper piston is received within the damping chamber and is operatively connected between the first and second end members and within the first spring chamber. A suspension system that includes a gas spring and gas damper assembly as well as a method of assembly are also included. | 05-19-2011 |
20130249184 | MOUNTING BRACKET ASSEMBLY FOR VEHICLE SUSPENSION COMPONENT AS WELL AS SUSPENSION ASSEMBLY, KIT AND METHOD INCLUDING SAME - A mounting bracket assembly, such as for securing a suspension component to a receiving element of sprung or unsprung mass of a vehicle, can include an internal mounting element. An external mounting element can be secured to the receiving element using a securement element. A suspension assembly for a vehicle and a method of assembly including such a mounting bracket assembly are also included. A mounting bracket kit is also included. | 09-26-2013 |
