Abstract
A temperature controlling assembly includes a thermoelectric device that is supported on or in a selected driveline component, such as an axle assembly or a brake assembly. The thermoelectric device preferably is controlled to operate in a first mode to remove heat from the selected component. In one example, fluid within a wet disc brake assembly is cooled using the thermoelectric device. In another mode of operation, the thermoelectric device provides heat to a selected lubricant. A controller monitors the temperature of the chosen component and causes the thermoelectric device to operate in the appropriate mode to maintain the component temperature within a desired range.
