An engine (18) delivers torque to a transmission drive shaft (12) through a flywheel (14) and a damper (16). The damper (16) includes a drive plate (30) attached to the flywheel (14) which is in turn mounted on the engine crankshaft (10). The damper (16) has two driven plates (32, 34) which are fixed on the transmission drive shaft (12). The drive plate (30) and driven plates (32, 34) have openings (48, 52, 54) for retaining springs (36, 36') through which torque is transmitted from the drive plate (30) to the driven plates (32, 34). The flywheel (14) has a plurality of arcuate segments (24) equally spaced apart around a peripheral edge to form a plurality of windows (26). One of the driven plates (32) has a plurality of radially extending fingers (56) each extending into one of the windows (26) so that gaps (26a, 26b) exist between each finger (56) and two adjacent arcuate segments (24). As torque is transmitted through the damper (16) the springs (36, 36') are compressed and the fingers (56) move in the windows (26). A single sensor (58) senses the passage of the arcuate segments (24), gaps (26a, 26b) and fingers (56) and generates an output signal which is analyzed by a microcomputer (60) to produce indications of engine RPM and torque transmitted through the damper (16). <IMAGE> |
