Abstract:
The invention relates to a method for estimating an amount of compressed air supplied to an air bellows (10) which forms part of an air supply system of a vehicle. The magnitude of an amount of compressed air supplied to the air bellows (10) is calculated by means of a computing model on the basis of the measured value representing the bellows height of the air bellows and the measured value representing the bellows pressure of the air bellows. The invention also relates to a computer programme product comprising computer programme codes for implementing a method according to the invention, and to an electronic control unit.
Abstract:
Die Erfindung betrifft ein Verfahren zur Regelung der Luftmenge in einer Niveauregelanlage für ein Kraftfahrzeug. Zur Regelung der Luftmenge werden zwei Luftmengenintervalle vorgegeben, wobei das erste Luftmengenintervall I 1 vollständig innerhalb des zweiten Luftmengenintervalls I 2 liegt. Wenn die Luftmenge in der Niveauregelanlage ausserhalb des Luftmengenintervalls I 2 liegt, erfolgt auf jeden Fall eine Regelung in den Luftmengenintervall I 2 hinein. Liegt die Luftmenge jedoch ausserhalb des ersten Luftmengenintervalls I 1 und innerhalb des zweiten Luftmengenintervalls I 2 , so erfolgt eine Regelung der Luftmenge in das erste Luftmengenintervall I 1 hinein nur im Betrieb des Kraftfahrzeuges.
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 present invention relates to a spring unit (1) for a shock absorber (100) intended for a vehicle. The shock absorber 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 (2b) 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).
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:
An end closure (260) is dimensioned for securement to a gas spring end member (204). The end closure is dimensioned to form a substantially fluid-tight, friction-fit connection with a flexible spring member (206) that is in an at least substantially-cured condition. The end closure (260) can include an end wall portion (298), a first side wall portion (300) that extends from along the end wall portion (298) and a second side wall portion (304) that is disposed radially inward of the first side wall portion and is axially-offset relative to the end wall portion. The second side wall portion at least partially forms a mounting seat that is dimensioned to form a substantially fluid-tight, friction-fit connection between at least the second side wall portion of the end closure (260) and the flexible spring member (204). A gas spring assembly as well as a suspension system and methods of assembly are also included.
