I. Overview: This test stand mainly for the automotive, motorcycle brake caliper repeated durability and performance test; dynamic monitoring of performance parameters; main technical features: 1 draw hand brake calipers dragging torque characteristic curve. 2, testing the caliper clamp body shell becomes. 3, dragging torque test power source maximum torque 20N. M. 4. Dragging torque test the power source for the speed of 50 revolutions / min (adjustable). 5, before dragging torque test high pressure filling, release repeat 0-3 times (adjustable), high-pressure air source 7.5MPa, high pressure tightness test, dragging display maximum torque lap 10, high pressure tightness testing time is less than 30 seconds. Second, to meet the standards: 1, QC T 316-1999 "car service brake test methods of fatigue strength." 2, QCT 564-2008 "passenger car brake performance requirements and test methods of." 3, QC / T 592-1999 "Car brake caliper assembly performance requirements and test methods of the" three, test parameters: 1, Input voltage: 220V ± 10% three-phase five-wire system, frequency: 50Hz ± 10%.
