| CURVES GIVING THE DIFFERENT BRAKING & THE PERCENTAGE OF BRAKING ON FRONT WHEELS FOR VARYING SERVO TORQUE MULTIPLICATION. THE BRAKING UNITS GIVEN ARE ASSUMING UNIT PEDAL PRESSURE & TAKEN AS THE LOAD IN THE CAM LINKS MULTIPLIED BY THE DRUM DIAMETERS. THIS DOES NOT ACCOUNT FOR ANY VARIATION IN THE EFFICIENCY OF THE BRAKES, COEFFT. OF FRN. ETC. THE SERVO SHOULD WORK BETWEEN THE LIMITS 'A' & 'B' THIS SHOULD NOT CAUSE APPRECIABLE ALTERATION TO THE DISTRIBUTION. TOTAL BRAKING ON STD. 40/50 545 UNITS. Y-Axis Left: BRAKING UNITS (0, 400, 800, 1200, 1600, 2000, 2400, 2800, 3200) X-Axis Bottom: SERVO MULTIPLICATION OF TORQUE (0, 1, 2, 3) Y-Axis Right: PERCENTAGE OF BRAKING GOING TO FRONT WHEELS (10, 20, 30, 40, 50%) Line Labels: TOTAL BRAKING, PERCENTAGE OF BRAKING TO FRONT, REAR BRAKING, FRONT BRAKING. | ||
