Abstract: An air spring height sensor has a PCR (Pulsed-Coherent-Radar) sensor encased in a housing attached to an air spring. The housing also provides an integral channel for adding air to an air spring or releasing air. The PCR sensor is aligned with a connector to orient the sensor with respect to the air spring to accurately determine the height of the air spring.

Abstract: A tire deflator includes a base, a cover, a poppet, and a biasing member. The base defines an air channel and a deflation port in selective fluid communication with the air channel. A body of the poppet configured to translate between an open pose in which the poppet is positioned to allow air to flow from the air channel through the deflation port and a closed pose in which the poppet is positioned to occlude the deflation port. The biasing member positioned within the base and exerts a closing force on the poppet to urge the poppet towards the closed pose. The poppet configured to release air from the air channel until air pressure within the air channel is at a set air pressure when the air pressure within the air channel is above the set air pressure.

Abstract: An adapter assembly that allows a wheel cover to be attached to a wheel has an insert, a plug, a key and a wrench. The insert attaches through a hole in the wheel cover and has prongs that lock behind a cap lip of the wheel. The plug is screwed into the insert via the wrench, and plug threads push out on the prongs, securing them behind the cap lip. The key is inserted into a locking space between the outer surface of the plug and the inner surface of the insert.
