Abstract:
PROBLEM TO BE SOLVED: To provide ride height leveling control for a dual air spring configuration. SOLUTION: An air suspension system is configured to adjust and maintain a desired vehicle ride height and spring rate. The air suspension system includes a plurality of air spring assemblies that each include a piston airbag and a primary airbag mounted around the piston airbag. A controller receives ride height input data and adjusts pressures within the primary and piston airbags until the desired ride height and spring rate is achieved. The controller accommodates for system hardware differences by varying flow rates into and out of the primary and piston airbags relative to each other. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
A multi-axle transport trailer having a plurality of axles includes a suspension comprising air bags associated with each axle, the air bags in communication with an air source, wherein air bags associated with different axles are capable of having different air pressures therein. The trailer further optionally includes a steering system associated with at least one axle, the axle including a tie rod connected between wheels on both ends of the axle, the steering system comprising cylinders configured to articulate the wheels, and a sensing device configured to monitor movement of the tie rod and facilitate actuating the cylinders to turn the wheels.
Abstract:
An air suspension device includes an exterior compressed air source (9) that is mounted on a pressure accumulation tank (50) to supply compressed air, and a control unit (ECU) that controls a compressor device (CMP) to boost air pressure within the pressure accumulation tank (50) to fill an air spring device (A1, A2, A3, A4) with the compressed air, the control unit (ECU) controlling first and second inlet and outlet on-off valves (71, 72), first and second tank on-off valves (81, 82), and control valve (61, 62, 63, 64) to supply at least compressed air within the air spring device (A1, A2, A3, A4) to the pressure accumulation tank (50) when a pressure level of air within the air spring device (A1, A2, A3, A4) comes to be greater than a predetermined pressure level, or when a vehicle height value comes to be greater than a predetermined value.
Abstract:
Methods and systems are provided for translating an adjusted medium pressure into performance of one or more selected functions, the method comprising: providing a pneumatic structure in which the medium is retained at a starting pressure, providing an adsorptive material operable within a range of temperatures that is proportionate with a range of medium pressures in which the pneumatic structure operates, and adjusting the temperature of the adsorptive material to effect a commensurate adjustment of the medium pressure to a target pressure; the system comprising: an adsorptive material that is in fluid communication with the pneumatic structure and operable within a range of temperatures that is proportionate with a range of medium pressures in which the pneumatic structure is operable, and at least one regulator for adjusting a temperature of the adsorptive material and effecting a commensurate adjustment of the medium pressure.

Abstract:
The invention relates to an integrated air-supply unit (1), in particular for air-suspension systems for motor vehicles, said unit comprising an air compressor (2) having an electric motor (3) and an air dryer (4). The air compressor (2) together with the electric motor (3), air dryer (4) and a number of pneumatic connections (8) form a functional unit.
Abstract:
The invention relates to a vehicle (3) comprising at least two axles (6, 7, 8) provided with at least two tires, the rotational axes of which are permanently parallel to each other, from one axle to the other. According to the invention, each axle (6, 7, 8) supports at least 10% of the load of the vehicle and at least two axles (6, 7, 8) support different loads during haulage. The invention further relates to a method for distributing the load between said two axles.
