Description

Fluid filter module Technical Field The present disclosure relates generally to fluid filter modules that may be used, for example, in a transmission system (e.g., for a traction motor), an internal combustion engine, and/or a motor vehicle. Background Conventional fluid filter module designs employ multiple parts and/or components to encapsulate the filter and direct fluid (e.g., transmission oil) through the filter for filtration. For example, some conventional filter modules employ a multipart housing to encapsulate the filter. The filter is disposed in the first housing portion and is covered by the second housing portion. The first housing portion, the second housing portion, and the filter are then connected to one another by welding (e.g., vibration welding). The welding of the two housing parts may form a joint between the two, which is a potential failure point, prone to undesired leakage and/or breakage. Furthermore, each part and/or component included in conventional fluid filter module designs requires specialized tooling, own tooling equipment, and may add additional steps to the module assembly process. Thus, as the number of parts and/or components increases, the cost of producing a conventional fluid filter module increases. Minimizing costs is a critical factor in ensuring market competitiveness, and is therefore critical. Accordingly, there is a need for an improved fluid filter module that reduces or eliminates one or more problems or disadvantages associated with existing fluid filter modules.
