Abstract
A wheel speed transducer including a magnetic device associated with a wheel and a sensor device associated with the axle of the wheel provides data indicative of the velocity of the wheel. A processor located at the axle receives the wheel speed data and processes it to perform antiskid control functions. The velocity data is stored in a data concentrator also associated with the axle. A tire pressure sensor, a brake temperature sensor and a brake torque sensor, each associated with the wheel, send data to the processor at the axle, for storage in the data concentrator. A transmitting antenna associated with the axle and in communication with the data concentrator transmits stored data to a receiving antenna associated with the wheel. A data port at the wheel and in communication with the receiving antenna provides an interface to an external device for receiving the data.
