Embodiment Construction

[0033] Although a primary transformer coil and a secondary transformer coil have been used for communication between a tire sensor and an axle to transmit tire pressure information through the axle, with a length of wire connecting the secondary coil directly to the tire pressure sensor, this has been Prove to be unreliable in terms of communication between the hub of the aircraft and the tire pressure sensor located on the rim that needs to be as much as nine inches away from the hub, especially since the electrical connection can be unreliable and easily damaged in the harsh aircraft wheel environment damage.

[0034] A tire pressure monitoring system has been developed in which an electronics unit located in the wheel hub communicates with a tire pressure sensor near the rim using a magnetic field. A coil centered on the axle and located in the hub generates the magnetic field. This magnetic field can be coupled to the tire pressure sensor receiving coil using a length of ...

Abstract

Aircraft tire pressure resonant ring link assembly, which electromagnetically couples the magnetic field between the axle electromagnetic adaptation transformer primary coil and the tire pressure sensor receiving coil for powering the tire pressure sensor, the assembly includes: a pair of spaced apart conductive connecting arms a single conductive primary loop electrically connected to a first end of the connecting arm and mounted adjacent to a secondary tire pressure sensor coil; and a circuit comprising a resonant tuning capacitor and a secondary coil at the first end of the connecting arm There are one or more conductive rings at both ends. The tire pressure sensor coil pair includes a transformer core, and the secondary resonant coil pair also includes a transformer core.

Description

[0001] References to related applications [0002] This application claims priority to non-provisional application Ser. No. 14 / 469,087, filed August 26, 2014, the entire contents of which are hereby incorporated by reference. Background technique [0003] The present invention relates generally to vehicle tire pressure control systems, and more particularly to a system for transmitting power from a control unit associated with a wheelhub to an aircraft tire pressure sensor and transmitting data between the aircraft tire pressure sensor and the control unit. The invention relates more particularly to a communication link between a tire pressure sensor on a wheel rim and a hub axle transformer for communication with control electronics, in particular for an aircraft. [0004] In an aircraft, it is useful to measure the pressure of each tire with a tire pressure sensor on the rim and display the tire pressure sensor information in the cockpit. This information from the tire pres...
