Abstract: An assembly (8) for a central tire inflation system includes a housing having a first end and a second end. The housing defines a fluid conduit disposed through the first and second ends. The assembly also includes one or more sensors (205, 210) having a portion disposed in the fluid conduit. Further, a power source (245) is in electrical communication with the sensor. The assembly additionally includes a kinetic energy device (220) in electrical communication with the power source. The kinetic energy device may comprise a magnet (255) sliding on a guide (265). As an alternative, the kinetic energy device may comprise a turbine (275).

Abstract: A dynamic weight shift suspension system for shifting the tandem axle loads on a vehicle. The system includes a first airbag connected between the drive axle of a tandem and the vehicle frame, and a second airbag connected between a tag axle of a tandem and the vehicle frame. The system also has a mechatronic control unit comprising at least one port and at least one solenoid. The mechatronic control unit is in direct fluid communication with the airbags and an air supply via fluid communication lines.

Abstract: A wheel end assembly for a tire inflation system includes a sealing ring disposed on an axle housing. The sealing ring includes a conduit formed therethrough in fluid communication with a conduit formed through a hub. The hub is rotatably disposed on the axle housing adjacent the sealing ring. An inner rotary seal is disposed between the sealing ring and the hub. An outer rotary seal is disposed between the sealing ring and the hub. The hub conduit is in fluid communication with the sealing ring conduit via an area between the inner rotary seal and the outer rotary seal. A bearing seal is disposed between the sealing ring and the hub. The bearing seal is disposed outboard of the outer rotary seal. The inner rotary seal, the outer rotary seal, and the bearing seal are each in sealing contact with the sealing ring.

Abstract: A tire inflation system including a wheel rim having an aperture through the radially exterior and interior surfaces thereof. A wheel valve assembly including a mounting portion coupled with the wheel rim interior surface. The mounting portion having an opening in fluid communication with the wheel rim aperture. A cap portion coupled with the mounting portion, defining a fluid inlet and a perforation in fluid communication. A valve at least partially disposed within the cap portion, and disposed parallel with the longitudinal axis of the wheel rim. A base portion coupled with the cap portion, and at least partially surrounding the valve. A fluid outlet defined by the base portion, and in selective fluid communication with the fluid inlet via the valve. A biasing member disposed at least partially around the valve, whereby the biasing member is compressed in the wheel valve assembly closed position.
