Abstract
A differential assembly include a housing defining an oil sump, a differential disposed in the housing, and a thermal-management system. The system includes an oil pump in fluid communication with the sump, a spool valve having an inlet connected to the pump, a first outlet, a second outlet, and a spool slidable to a first position in which the inlet is in fluid communication with the first outlet and to a second position in which the inlet is in fluid communication with the second outlet. The spool valve further has a chamber containing wax configured to move the spool according to a temperature of the wax such that the spool is in the first position when the temperature of the wax is within a first temperature range and is in the second position when the temperature of the wax is within a second temperature range.
