An assembly to be mounted in an axle spindle for communicating pressurized air from the axle to a rotary union in a tire inflation system. The assembly includes an arbor having an air flow channel extending therethrough, a flange intermediary of the arbor ends and an axially inclined portion proximate the flange. A sealing member is carried by the flange for forming an airtight seal with the axle spindle. A split ring locking assembly is disposed about the inclined portion of the arbor that is comprised of a plurality of segments held by an expansible retention spring. The segments move radially outwardly upon the locking assembly being moved along the inclined arbor portion and engage the axle spindle, securing the plug assembly within the spindle, A fastening member threadably engages the arbor for urging the locking assembly along the inclined arbor portion to effect securement of the plug assembly within the axle spindle.

A rotary union is integrated into the interior of a heavy-duty vehicle hub cap. The hub cap includes a cylindrical sidewall, and an outboard wall that is integrally formed with an outboard end of the sidewall, and which extends generally perpendicular to the sidewall. The hub cap also includes a radially-extending flange that is formed on an inboard end of the sidewall, which receives fasteners to mount the hub cap on a wheel hub. The sidewall and the outboard wall form an interior compartment in the hub cap, and a rotary union is mounted to the hub cap in the interior compartment. The rotary union is mounted on the inboard surface of the outboard wall of the hub cap and is in general axial alignment with an axial centerline of a wheel end assembly, providing fluid communication from a tire inflation system to the tires of the vehicle.

A method and apparatus is disclosed for remotely and robotically installing an organic, monolithic, structural and non structural, circumferential and partial radius membranes in conduits, pipelines or passageways. The included apparatus has the mechanical function to manually or automatically center the liner dissipation device in any geometrical shape. The included apparatus possesses the remote controlled capability to manipulate centrifugal dissipation of the liner to afford consistent thickness on any shaped profile or flat surface of the pipe wall surface. The apparatus includes a manual or automatic mechanical scissoring device for elevation changes and a manual or automatic rotational table for shaft alignment. The apparatus includes a means of automated self alignment by way of proximity sensors. The pendulum oscillation bracketing incorporates a fluid driven motor assembly communicating with a bored shaft and integrates as many as two offset dissipation devices. The included apparatus has both fluid and electrical rotary unions to transmit fluids and current from fixed ports to a rotating shaft assembly. The included apparatus has a mechanical function facilitating cutting and retrieval of cured spray build up on the spray orifice. This method and apparatus will allow for continuous lining applications of any thickness in one pass, in conduits and passageways employing multi component liquid polymers with rapid mechanical properties formation.

A rotary union assembly for an automatic tire inflation system for maintaining the pressure in the tires on a tractor trailer or other vehicle having a source of pressurized air for communication with the tires. The assembly communicates the tires with the air source through the axle interior using a conduit having a rigid portion and a flexible portion that extends between a support in the axle spindle and a rotary union housing secured against the outside end surface of the hub cap so as to be outside the wheel lubrication compartment and rotatable with the hub cap. The two-component conduit allows for a durable seal with the support in the axle spindle and accommodates misalignment of the rotary union housing with the conduit support. Relief valves in the housing prevent excessive pressure buildups in the housing and in the hub cap in the event of an air leak.

An intelligent tire pressure management system capable of real-time tire pressure monitoring, vehicle load detection, and automatic tire inflation and deflation for maintaining optimal tire pressure in a commercial vehicle. Additional functions include counting tire rotations for calculating and recording distance travelled for each tire, and detecting wheel sliding due to locked-up tires. The system includes a chassis-mounted control box connecting to the vehicle air supply, a hubcap-mounted dual wheel valve apparatus integrated with a rotary union assembly that connects through the vehicle hollowed axles to the air tubes from the control box. The inflation / deflation supporting dual wheel valve apparatus has an embedded electronic unit that monitors individual tire pressure and temperature in real time, and communicates with the control box over the power line. Furthermore a load sensor integrated with the control box provides the system with the current vehicle load information. With readily available real time tire pressure data and current vehicle load information, this system can intelligently adjusts tire pressure to the desired level when necessary and, as a result, prolongs tire life, improves fuel economy, reduces the vehicle maintenance costs, and promptly alerts the driver of low, leaky or flat tire conditions for enabling the driver to take immediate corrective actions.

Spaced apart counter-rotatable forward and aft rows of forward and aft propellers are mounted on forward and aft rotatable frames. Hydraulic rotary forward and aft pitch change actuators on the frames are operable for controlling pitch of the propellers. A hydraulic fluid supply outboard of the frames is connected to forward and aft rotary unions which are operable for transferring hydraulic fluid between forward and aft union stators to forward and aft union rotors mounted within the forward and aft rotary unions. The forward union rotor is operable to transfer the hydraulic fluid from the forward rotary union to the aft pitch change actuators and the aft union rotor is operable to transfer the hydraulic fluid from the aft rotary unions to the forward pitch change actuators. The forward and aft rotatable frames counter-rotatably mounted on a structural frame located forward or aft of the propellers.
