Determination of air entrainment characteristics of transmission fluids in a new laboratory apparatus - (PPT)

摘要

The ZF air entrainment test meets our objectives, mainly: Test volume 160 ml; Online data logging; High discrimination power; Applicable to different fluids (AT-, DT-, MT-fluids, axle and shock absorber fluids); Good correlation to transmissions. ZF has a powerful tool for a quick and target-oriented optimisation of the air entrainment behaviour of their transmission fluids to ensure: smooth operation; efficient thermal transport; long lifetime of the lubricant and the components; absolute leak tightness.
