Latest Patents

One of Gwak's latest patents is for a hybrid powertrain. This innovative design includes a first shifting module with a motor input shaft directly connected to a motor, forming two shifting stages with the largest gear ratios in sequence. Additionally, it features a second shifting module with an engine input shaft that is concentrically mounted with the motor input shaft. This module connects to an engine through a main clutch and provides the remaining shifting stages. The design also incorporates a center synchro to intermit the motor and engine input shafts, along with a continuous variable device that allows for a controlled friction force to adjust gear ratios.

Another notable patent is for a clutch device designed for a transmission. This device consists of a first body and a second body mounted coaxially. A friction element is placed between these two bodies, and a friction piston applies hydraulic pressure to engage the friction element. The device also includes a retractable mechanism with a dog clutch that restricts rotation between the two bodies, allowing for repeated engagement and disengagement through axial pressure. An operation piston provides the necessary pressure to the retractable mechanism.
