ABSTRACT:
A vehicular drive train includes a torque converter having a bladed impeller element, a bladed turbine element, and a bladed reactor element defining a toroidal chamber within an engine-driven rotating housing. The impeller element is relatively inaccessible because it is contained within the rotating housing, yet it is desirable to monitor its speed in order to better control the operation of the drive train. A speed sensor apparatus is therefore provided which includes a ring magnet connected to rotate with the impeller element, a sensor unit connected to a stationary carrier assembly close to the ring magnet, an external electrical connector, and a wiring harness interconnecting the sensor unit and the electrical connector. Preferably, the sensor unit delivers two digital pulse signals to an associated microprocessor for precise control of the input clutch assembly. The ring magnet and the sensor unit are located radially inwardly of the toroidal chamber such that no additional space is required.
