His innovative approach has led to the creation of a patent that enhances the functionality of parallel-axis differentials.

Latest Patents

Yehl holds a patent for a lubrication system designed for a parallel-axis differential. This system facilitates the flow of lubrication fluid between the planet gears and their respective housing pockets. A further set of pockets is formed within the differential housing to receive and retain lubrication fluid that is continuously supplied during vehicle operation. Holes, slots, and grooves are strategically placed to direct the lubrication from the fluid-storage pockets to the cylindrical bearing surfaces and the interfaces between the planet-gear pockets and the end faces of their respective planet gears. The design ensures that at least one fluid-storage pocket retains lubricating fluid during non-rotational periods, thereby assuring adequate lubrication upon startup.
