Abstract
A brake cover (18) and shaft (24) rotate with a pedal lever (20) relative to a central section (14) of the housing (12) rotate a pedal gear (76). The pedal gear (76) rotates a sensor gear (74) to rotate a sensor arm (46) about a sensor axis (48). The sensor arm (46) supports sensor members (58) that move along sensor bands (50) to generate an electrical signal. As the brake cover (18) rotates with the pedal lever (20) it uncoils coil springs (84) to cause brake shoes (80) to pivot radially outward about respective posts (82) frictionally engage the interior surface (78) of the central section (14) to thereby provide a resistance or hysteresis to movement of the pedal lever (20). One feature resides in at least two elements (74, 76) to interconnect the sensor arm (46) and the pedal arm (20) to reduce space while maintaining the requisite movement of the sensor members (58) over the sensor bands (50) and the other feature resides in spacing the braking mechanism axially from the sensor arm (46) in radially overlapping relationship to one another along the pedal axis (A).
