An axle assembly having a ballast insert assembly and a method of control. The ballast insert assembly may have an inflatable bladder that may be disposed in a cavity. The volume of lubricant in the cavity may be greater when the inflatable bladder is deflated than when the inflatable bladder is inflated.

Axle assembly having a ballast insert assembly and a method of control

A tire inflation system having a spindle that is configured to support a wheel bearing. A passage for routing pressurized gas may be provided with the spindle or with a sleeve that may be disposed on the spindle.

Tire inflation system with a passage for routing pressurized gas

A tire inflation system and a method of control. The tire inflation system may include a damped valve that moves from a closed position to an open position faster than from the open position to the closed position.

Tire inflation system and method of control

A tire inflation system having a conduit, a hub, and a seal assembly. The hub may be rotatably mounted on a spindle and may have a passage. The seal assembly may have a seal passage that fluidly connects the conduit to the passage.

Tire inflation system having a passage for routing pressurized gas through a hub

A tire inflation system for a vehicle. The tire inflation system may include a gas supply subsystem that may supply pressurized gas to a tire via first conduit that may be connected to an axle shaft.

Tire inflation system with external pressurized gas routing

An example roll control device uses differential pressure values, for example, that are conveyed by a motor driven pump to a first actuator associated with a first stabilizer. The differential pressure values are also conveyed from the motor driven pump to a second stabilizer through a proportional valve in one example. In another example, multiple actuators are utilized with each actuator being associated with a separate motor driven pump in communication with a common controller.

Roll control devices

A roll control system is provided that includes first and second dampers each having fluid. A pump fluidly interconnects the first and second dampers. A motor is connected to the pump. A controller is in communication with the motor. The controller is configured to command the motor to drive the pump and transfer fluid between the first and second actuators in a desired direction in response to a roll signal. The pump provides fluid from one of the first and second dampers to the other of the first and second dampers in response to being driven by the motor. The roll control system can be used on front and rear axles to provide improved overall stability for the vehicle. In one example, a common motor is used to drive first and second pumps, which are respectively associated with the front and rear axles.

Damper actuated active roll control

A roll control device includes at least one actuator having first and second chambers. A pump is in fluid communication with the first and second chambers and is configured to transfer fluid between them. A motor is connected to the pump and is in communication with a controller. The controller is configured to selectively command the motor to drive the pump in response to a roll signal and transfer fluid between the first and second chambers in a desired direction. A failsafe valve is arranged between the pump and first and second chambers in one example. The failsafe valve includes a first open position in which the first and second chambers are fluidly connected to one another and bypass the pump.
