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.

  1. Software version check: Comparison of the software version in the control units with the current stored and released version number.
  2. Venting hydraulic system: Trigger a venting routine in the control unit using a diagnostics job and remove the remaining air.
  3. 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.

NovoPS Test Stand Software

The NovoPS test stand software is a Windows-based solution that is programmed in-house and optimised for the respective test task. As the interface to the user, the uncomplicated user interface provides intuitive access to all functions of the test stand. Moreover, both the connection of the test stand to the customer's conveyor systems as well as its integration into the existing network environment is taken into account. This enables the data acquired to be processed and evaluated independently of the test stand.
