The test stand is designed to allow fully automated leak testing, oil filling and function tests for clutches in rear-axle drives. As an “end-of-line” test stand, it is integrated into an assembly line. Specimens are rear-axle drives with an integrated differential, which are equipped with a hydraulically operated multi-plate clutch.
•Oil filling at an inclined position
•Function test
•Drive unit with torque measurement flange
Functional test/EOL test
•Software version check: Comparison of the software version in the control units with the current stored and released version number.
•Venting hydraulic system: Trigger a venting routine in the control unit using a diagnostics job and remove the remaining air.
•Measurement of adjustment accuracy: Record and evaluate the clutch curve using a pre-defined speed-torque profile.
Oil filling
Filling the rear axle differential with the operating medium in the optimal filling position. For dosage the correct volume of oil, a batcher with the ASR 20 control system is used
Leak test
Evaluation of leakage rate by means of leak test computer (1000 mbar)
