INTEGRATED CROSSLINK VALVE

An air spring suspension system includes a first air spring that has a first volume with a first pressure that is configured to provide a first spring stiffness to a first suspension assembly. A second air spring has a housing with a second volume with a second pressure that is configured to provide a second spring stiffness to a second suspension assembly. The second air spring includes a piston that is arranged in the second volume. One of the housing and the piston includes a first mounting structure that is configured to connect to a vehicle chassis. Another of the housing and the piston includes a second mounting structure that is configured to connect to the second suspension assembly. The second air spring also includes a fluid connection on the housing. The second air spring further includes a crosslink valve that is disposed in the housing and movable between open and closed positions. The crosslink valve is configured to selectively fluidly connect the second volume to the fluid connection. A crosslink line is fluidly connected to the first volume of the first air spring and the fluid connection on the second air spring. A controller is in communication with the crosslink valve. The controller is configured to command the crosslink valve between the open and closed positions in response to an input.
