Latest Patents

One of his latest patents is a power transmission apparatus of a hybrid electric vehicle. This invention features a planetary gear set that is strategically placed on the first motor shaft of the first motor-generator. It includes a planet carrier connected to an engine shaft, a sun gear linked to the first motor shaft, and a ring gear that connects to a drive gear through a one-way clutch. The design also incorporates a second motor shaft gear connected to the second motor shaft of the second motor-generator, an output shaft positioned between the engine shaft and the second motor shaft, and a brake unit that selectively connects the sun gear and the ring gear to the transmission housing. Notably, the output shaft is externally gear-meshed with both the drive gear and the second motor shaft gear through a driven gear, as well as with a final reduction gear of the differential gear through an output gear.

Another significant patent by Jaewook Lee is a power transmission system for a hybrid electric vehicle. This system features a second motor shaft gear of a second motor-generator that is positioned on one side of a second motor shaft, which runs parallel to the first motor shaft. The invention includes a planetary gear set on the first motor shaft, where one rotation element is fixedly connected to the engine output shaft and the first motor shaft, while the remaining rotation element engages with the other rotation element. The drive gear is connected to the remaining rotation element through a one-way clutch, and an output shaft is placed in parallel between the engine output shaft and the second motor shaft, engaging with both the drive gear and the second motor shaft gear through a driven gear.
