摘要： A center section assembly for mounting inside the housing of a hydrostatic or hydraulic drive apparatus is disclosed. The center section includes generally flat side edge surfaces formed adjacent and perpendicular to a cylinder block running surface, and shaped to engage a channel formed in an internal surface of the housing to secure the center section to the housing. The assembly may also include a filter using a connection member to permit the filter to slide on and engage the peripheral edge of a flange formed on the center section.

摘要： Apparatus and methods for cooling controller assemblies for electric utility vehicles are disclosed. Auxiliary implements powered by electric motors onboard a utility vehicle create airflow that is captured and directed to provide increased ambient airflow across heat sinks used to dissipate heat from heat generating components. Airflow across heated surfaces is further created by vehicle movement and vacuum pressure. Fins and other heat dissipating architecture are employed. Features of the cooling systems enable increased controller assembly functionality and/or decreased controller assembly package size.
