ABSTRACT:
Four different torque sensing arrangements are described: one for an engine driving a torque converter housing (2) for an automatic transmission, two are for engines with two piece flywheels (31, 35 and 80, 86) and one for a three piece coupler (61, 64, 67), where sets of cantilever blade type springs (18, 48, 74, and 118) are arranged to allow a limited extent of rotation of driving and driven members proportioned to the torque being transmitted from the engine to the transmission and vice versa. The relative movement between the member is detected by electronic sensing devices (22, 23; 52, 53; 78; and 132, 134) generating signals transmitted to an on board microprocessor (25 and 55) or other electronic unit.
