WHEEL LOCK CONTROL BRAKING SYSTEMS

A WHEEL LOCK CONTROL SYSTEM OFFERS THE ABILITY TO APPROACH THE PERFORMANCE OF THE IDEAL BRAKE DISTRIBUTION. IDEAL PERFORMANCE REQUIRES VARYING BRAKING EFFORT DISTRIBUTION ON THE FRONT AND REAR AXLE OF THE VEHICLE. FACTORS AFFECTING THE DISTRIBUTION ARE LISTED. VARIOUS ASPECTS OF THE WHEEL LOCK CONTROL SYSTEM ARE DISCUSSED. WHILE FOUR WHEEL LOCK CONTROL IS OPTIMUM, IT IS TWO OR THREE TIMES MORE COMPLEX THAN THE TWO REAR WHEEL LOCK CONTROL DUE TO FRONT WHEEL SENSING, ADDED CONTROLLER REQUIREMENTS AND ADDED BRAKE MODULATION. REAR WHEEL LOCK CONTROL ON A VEHICLE GIVES ATTITUDE STABILITY DURING MAXIMUM DECELERATION STOPS, GIVES FRONT TO REAR BALANCE AND ALSO MAY IMPROVE STOPPING DISTANCES BETTER THAN ON A VEHICLE WITHOUT WHEEL LOCK CONTROL. WHEEL LOCK CONTROL SYSTEMS APPEAR ON SPECIALITY CARS WHICH HAVE THE GREATEST VARIATION IN FRONT TO REAR BRAKE BALANCE AND BRAKE DISTRIBUTION NEED. FIGURES ILLUSTRATE AN ELECTRONIC WHEEL LOCK CONTROL SYSTEM FOR ONE AXLE; FUNCTION OF A REAR WHEEL LOCK CONTROL SYSTEM; WHEEL SPEED SENSOR; DRIVE LINE SPEED SENSOR; AND OTHER COMPONENTS OF THE SYSTEM. FIELD SERVICING OF THESE SYSTEMS REQUIRES A CLEARLY DEFINED DIAGNOSTIC PROCEDURE AND AN EASY MEANS OF SERVICING. THE PROGRAMMED DIAGNOSTIC INSTRUCTION CHART PROVIDES AN EASY MEANS. REDUCTION IN COMPLEXITY AND INCREASED RELIABILITY IS NOTED IN THE DEVELOPMENT OF PROBE TYPE SENSORS, SIMPLER ELECTRONIC CIRCUITING AND TYPES OF MODULATORS.
