An apparatus for assembling a brake monitor upon a brake actuator, wherein the brake monitor includes an annular push rod sleeve having a first sensor element, preferably a magnet, and a second sensor element fixed relative to the brake actuator housing. The installation apparatus includes a push rod sleeve adjustment member which supports the push rod sleeve and movable by a servomotor, a programmable logic controller (PLC), preferably including an analog card, operably connected to the second sensor element including a power supply having a predetermined voltage. The PLC controls the servomotor to adjust the axial position of the push rod sleeve on the push rod until the second sensor element senses a predetermined voltage, and the apparatus then fixes the push rod sleeve on the push rod. The installation apparatus also locates an annular sensor sleeve within the brake actuator housing and disposes the push rod through the sensor sleeve and aligns the components of the housing, push rod, return spring, etc.
An Apparatus for assembling a brake monitor on a brake actuator, said brake actuator including a housing having an end wall, an opening through said end wall and a reciprocating piston within said housing having a push rod extending through said opening in said housing for actuation of a vehicle brake, said brake monitor including an annular push rod sleeve slideably received around said push rod having a first sensor element and a second sensor element fixed relative to said housing, said apparatus including an adjustment sleeve clamp member releasably supporting said push rod sleeve and movable by a servomotor relative to said brake actuator housing, a programmable logic controller operably connected to said second sensor element including a power supply having a predetermined voltage, and said programmable logic controller controlling said servomotor to adjust the axial position of said sleeve on said push rod relative to said second sensor element until said second sensor element senses a predetermined voltage.
An apparatus for assembling a brake monitor on a brake actuator, said brake actuator including an enclosed housing having an end wall, an opening through said end wall and a reciprocating piston within said housing having a push rod extending through said opening through said end wall of said housing for actuation of a vehicle brake, said brake monitor including an annular push rod sleeve slideably received around said push rod having an elongated magnet fixed to said push rod sleeve and a sensor fixed relative to said housing adjacent said opening, said apparatus including a calibration clamp member releasably supporting said sleeve and moveable by a servomotor relative to said brake actuator housing, a programmable logic controller including an analog card operably connected to said sensor including a power supply having a predetermined voltage, and said programmable logic controller controlling said servomotor to adjust the axial position of said push rod sleeve on said push rod and said magnet relative to said sensor until a predetermined voltage is sensed by said sensor and said apparatus then fixing said push rod sleeve on said push rod.
An apparatus for assembling a brake monitor on a brake actuator, said brake actuator including a housing having an end wall, an opening through said end wall and a reciprocating piston within said housing having a push rod extending through said opening in said end wall of said housing for actuation of a vehicle brake, said brake monitor including an annular push rod sleeve slideably received around said push rod having an elongated magnet fixed to said push rod sleeve extending longitudinally relative to said push rod, and a Hall-effect sensor fixed to said housing within the magnet field of said magnet, said apparatus including a push rod sleeve adjustment member releasably supporting said push rod sleeve and moveable by a servomotor relative to said brake actuator housing, a programmable logic controller having an analog card operably connected to said Hall-effect sensor including a power supply having a predetermined voltage, and said programmable logic controller controlling said servomotor to adjust the axial position of said push rod sleeve on said push rod and said magnet relative to said Hall-effect sensor until said Hall-effect sensor senses a predetermined voltage.
