Abstract

The invention relates to method for performing a leakage test on a component through a non-linear system. The present invention generally relates to a system and method for performing leakage test onthe component. Disclosed in various embodiments are a monitor for performing the leakage test arrangements and the method and system for performing the leakage test on components (e.g., automotive components including transmission components, transmission assemblies including drying assemblies or oil-pretreated assemblies, engine components, engine assemblies, battery packs, or shafts).

Description

technical field [0001] The present disclosure generally relates to systems and methods for leak testing components. Background technique [0002] Perform transmission assembly leak testing or final leak testing to ensure proper assembly of components or to ensure that all sealing surfaces are functioning as intended. Leak detection is important for a variety of reasons. For example, a transmission fluid leak in a transmission assembly can seriously impair the performance of the transmission assembly. Several methods exist for testing components for leaks, such as pressure decay measurements, flow-based leak testing such as measuring air mass flow, or tracer gas testing with helium. These test methods suffer from several problems that limit the effectiveness or efficiency of the test methods. For example, flow-based methods require that measurement / testing of the component be done before the component's leak rate can be determined. In other examples involving transmission...
