A wheel end assembly having a spindle, a hub, and a rotary seal assembly. The spindle may have a spindle air passage. The hub may have a hub air passage and an annular hub chamber that may extend around an axis. The rotary seal assembly may fluidly connect the spindle air passage to an inlet of the annular hub chamber.

Provided is a puncture repair liquid holding container. An outflow channel in a cap mounted to an opening portion of a container body for discharging the puncture repair liquid inside the container interior to a container exterior includes a straight portion including an open end opening toward inside the container body and a closed end terminating inside the cap, and a branching portion including a communicating end communicating with an intermediate area of the straight portion and an open end opening toward the container exterior. A through-hole is at the closed end of the straight portion. A projection on a closing plug and slidably inserted to the straight portion is slidably inserted to the through-hole. States are switchable between open and closed states in which the outflow channel is opened and closed by the closing plug and the projection is positioned in the through-hole or projects from the through-hole.

A tire pressure control system can include a pneumatic line with a first end in fluid communication with an interior of a tire and a pressure sensing device configured to acquire pressure data within the tire measured from the single pneumatic line. A motion sensing device can be configured to acquire motion data of the tire pressure control system. A microcontroller can receive the pressure data from the pressure sensing device and the motion data from the motion sensing device. A pneumatic solenoid in fluid communication with a second end of the single pneumatic line can be in an initial, closed position. The microcontroller can open the pneumatic solenoid and release fluid from the interior of the tire when the pressure data and motion data meet preset conditions.

An air system and method includes an air compressor, a temperature sensors, a valve, and a controller. The air compressor is configured to receive filtered air. The temperature sensor is positioned at or near an outlet of the air compressor and configured to sense a temperature at or near the outlet of the air compressor. The valve is operatively connected to an outlet of the air compressor and external to the air compressor. The controller is configured to monitor the sensed temperature at the outlet of the air compressor and control the valve to permit air to flow from the outlet of the air compressor through the valve to unload the air compressor if the sensed temperature exceeds a threshold temperature.

A system for detecting pressure and wear conditions of tires that includes a module positioned inside each wheel of a vehicle. The module includes sensors, a processor, a transmitter and a power source for powering the module. The output from the sensors in each wheel is fed to the processors of each wheel for data processing and the data is transmitted by the transmitter in each wheel to a receiver and data processor located outside of the wheels. The data processor is designed to analyze the received processed data from the modules, and to provide alerts based on stored information and by comparing the processed data from the first wheel with the processed data from the second wheel.

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).

Embodiments of the present disclosure relate generally to generating and utilizing three-dimensional terrain maps for vehicular control. Other embodiments may be described and/or claimed.

A regulator for establishing outlet fluid pressure. The regulator includes a valve body having a fluid pressure inlet in selective fluid communication with a fluid pressure outlet. A pilot pressure inlet is formed in the valve body and in fluid communication with a source of pilot pressure. Valving structure in the valve body establishes outlet fluid pressure as a function of pilot pressure. First adjustable structure within the valve body may establish a minimum outlet fluid pressure threshold without regard to pilot pressure. Second adjustable structure within the valve body may establish outlet fluid pressure offset relative to pilot pressure.

A wheel hub assembly apparatus comprising a housing configured for operative fitment to a wheel hub assembly. Also included is at least one air pressure sensor having a fluid connection for in situ fitment to tire valve and configured to selectively sense a pressure of a tire mounted on the wheel hub assembly, a temperature detector configured to detect an ambient temperature within the wheel hub assembly, a display configured to provide external display of information, and a controller arranged in signal communication with the pressure sensor, temperature detector and display, the controller configured to receive sensed pressure and/or detected temperature and to display same via the display.
