Latest Patents

One of his latest patents is a driving force transfer apparatus for four-wheel drive vehicles. This invention features a dog clutch structure positioned at both sides of the first and second output axles. The first output axle connects to driven road wheels, such as rear wheels, while the second output axle connects to non-driven road wheels, like front wheels. The dog clutch structure allows for the connection of the first output axle to the second output axle, enabling all four road wheels to engage in a four-wheel drive state during low-speed gear range positions. This design includes a play in each tooth space structure, facilitating smooth meshing of the clutch and reducing the operating force required for the sub-transmission mechanism lever.

Another significant patent is related to a transmission system. This sub-transmission of a transfer unit includes a shift sleeve that can move to a neutral position, disengaging from both high-speed and low-speed gear sets. Once in the neutral position, it can engage with either gear set to transfer the driving force from the input shaft to the output shaft. The output shaft is designed with an annular friction member that contacts the input shaft, effectively reducing the rotational speed and minimizing gear screeches during transitions between low- and high-speed positions.
