Abstract
A pneumatic suspension system for a vehicle, in which the pneumatic suspension system includes a supply tank, a first set of air springs positioned on a first side of the vehicle; a second set of air springs positioned on a second side of the vehicle, and a dual-action dynamic valve positioned between the first set of air springs and the second set of air springs. The dual-action dynamic valve is connected to the supply tank, the first set of air springs, and the second set of air springs by a series of air hoses. The dual-action dynamic valve is adapted to supply air to either one of the first set of air springs or the second set of air springs while simultaneously exhausting air from the other one of the first set of air springs or the second set of air springs.
Claims21
A vehicle suspension dual-action dynamic valve comprising:
- an upper housing mounted on a lower housing to form a valve body, wherein the valve body defines a chamber extending between the upper housing and the lower housing;
- the lower housing comprising a plurality of ports communicating with the chamber, wherein the plurality of ports include a supply port positioned on a first side of the lower housing, an exhaust port positioned on a second side of the lower housing opposite to the first side of the lower housing, a first spring port positioned on a third side of the lower housing, and a second spring port positioned on a fourth side of the lower housing opposite to the third side of the lower housing;
- a control arm having a first end attached to an upper surface of the upper housing, wherein the control arm is configured to rotate about the valve body in response to extension or compression of the vehicle suspension;
- a shuttle mechanism positioned in the chamber of the valve body and connected to the control arm by a supporting element, wherein the shuttle mechanism is configured to rotate about the supporting element within the chamber of the valve body;
- and
- wherein the shuttle mechanism is configured to establish communication between one of the supply port or the exhaust port with one of the first spring port or the second spring port and to simultaneously establish communication between the other one of the supply port or the exhaust port with the other one of the first spring port or the second spring port.
A method for adjusting air pressure of a pneumatic suspension system of a vehicle comprising a supply tank, a first set of air springs on a first side of the vehicle, a second set of air springs on a second side of the vehicle, and a dual-action dynamic valve positioned between the first set of air springs and the second set of air springs, wherein the dual-action dynamic valve is connected to the supply tank, the first set of air springs, and the second set of air springs by a series of air hoses, the method comprising:
- supplying air from the supply tank to the dual-action dynamic valve in response to an extension or compression by the first set of air springs or the second set of air springs;
- supplying air from the dual-action dynamic valve to one of the first set of air springs or the second set of springs that is being compressed;
- removing air by the dual-action dynamic valve from the other one of the first set of air springs or the second set of air springs that is being extended;
- and
- wherein the steps of supplying air from the dual-action dynamic valve to one of the first set of air springs or the second set of springs that is being compressed and removing air by the dual-action dynamic valve from the other one of the first set of air springs or the second set of air springs that is being extended occurs simultaneously.
A rotary disk for a vehicle suspension dual-action dynamic valve, the rotary disk comprising:
- a disk body having a first surface and a second surface, wherein the second surface of the disk body faces opposite to the first surface of the disk body;
- a central aperture extending entirely through disk body from the first surface to the second surface;
- a plurality of grooves or through holes spaced around the central aperture, and each groove is recessed from the first surface of the disk body;
- and
- the plurality of grooves or through holes include a first blind groove or through hole, a second blind groove or through hole, a third blind groove or through hole, and a fourth blind groove or through hole;
- wherein each blind groove or through hole forms an arcuate shape and is disposed along the periphery of the rotary disk.
