Abstract
A drive module with a housing, an electric motor coupled to the housing, a differential assembly, a transmission, and a filter-strainer assembly. The housing has an exterior wall member that defines an internal cavity and a suction tube. The internal cavity at least partly forms a lubricant sump with a sump outlet. The suction tube is spaced apart from and does not intersect the internal cavity such that the suction tube is not in direct fluid communication with the internal cavity. The differential assembly and transmission are received in the internal cavity and the transmission transmits rotary power between the electric motor and the differential assembly. The filter-strainer assembly is coupled to the housing and has a filter-strainer inlet, which is coupled in fluid communication to the sump outlet, and a filter-strainer outlet, which is directly coupled in fluid communication to a suction tube inlet of the suction tube.
