An automotive axle includes a housing including gears and a bath lubricating the gears, the bath including gear oil and about 0.1 to 5 wt. % secondary alcohol ethoxylate based on total weight of the bath such that during automotive operation at temperatures less than a threshold, reverse micelles form to trap air bubbles in the bath, emulsifying the bath, and at temperatures greater than the threshold, the reverse micelles dissipate.

Vehicular gear system friction reduction

A system for regulating lubricant temperature within a vehicle axle is provided. A differential housing has a primary chamber that contains the differential, and a secondary chamber separated from the primary chamber. A sump is in the primary chamber for collecting lubricant. An inlet to the secondary chamber allows the lubricant to flow from the primary chamber into the secondary chamber. An outlet to the secondary chamber allows the lubricant stored therein to be purged into the sump. When the lubricant is below a certain threshold temperature, a temperature-responsive valve is configured to close to inhibit the fluid to travel through the outlet. When the temperature of the lubricant rises to exceed the threshold, the valve is configured to open and permit the fluid to travel through the outlet.

Differential with lubricant control

Methods and systems are provided for a phase change material (PCM) integrated radiator. In one example, a method may include adjusting a radiator control valve into a first position to flow coolant only through a first zone of a radiator containing phase change material (PCM) and not through a second zone of the radiator not containing phase change material. The method may further include adjusting the radiator control valve into a second position to flow coolant only through the second zone of the radiator and not the first zone.

System and methods for a high temperature radiator heat absorber

A differential is provided. The differential includes a housing that has a sump, an input shaft, a ring gear, a carrier that is affixed to the ring gear, and a diverter. The sump is configured to collect lubricating fluid. The ring gear is configured to transfer lubricating fluid out of the sump. The diverter is configured to direct the lubricating fluid to the input shaft and carrier.

Differential and differential lubricating fluid management system

A vehicle is provided. The vehicle includes a power source, at least one wheel, a gearbox. The gearbox includes a housing, gearing disposed in the housing, and an insulator disposed between the gearing and the housing. The gearing is configured to couple the power source to the at least one wheel. The insulator is configured to reduce thermal energy losses of a fluid that lubricates the gearing.

Vehicle and insulating device for gearbox

An axle includes a differential, a cover, and a heat absorber. The differential has a ring gear disposed within a housing. The ring gear is configured to pump a lubricating fluid. The cover is attached to the housing. The heat absorber is attached to the cover within a pump path of the ring gear. The heat absorber has a phase-change material disposed within the heat absorber configured to absorb heat from the lubricating fluid. A method to control fluid temperature in a vehicle axle is also included.

Axle heat absorber

A vehicle includes axle housing, a differential and a ring gear, a scraper port, and a reservoir. The housing has a cover forming a heat exchanger having a coolant side and a lubricant side. The differential and ring gear are configured to pump a lubricating fluid. The scraper port is disposed at a bottom of the heat exchanger adjacent to the ring gear and is configured to direct the lubricating fluid through the lubricant side of the heat exchanger. The reservoir is disposed at a top of the heat exchanger and is configured to receive and store the lubricating fluid from the lubricant side of the heat exchanger.
