Latest Patents

One of Hsieh's latest inventions is the auto-locking torque distributing mechanism. This mechanism comprises a main plate that receives two gear sets. On either side of the main plate, slots and apertures are formed, which partially communicate with each other. The sleeve assembly includes a covering unit with an opening enclosed by a first wall, allowing each aperture to connect with the opening. This design ensures that when one wheel slips and spins faster than the other, the sleeve assembly retains fluid to prevent leakage. The fluid is then sucked into the aperture, entering the slot and circulating among the gear sets. This process limits the torque sent to the slipping wheel while distributing more torque to the non-slipping wheel, thereby maintaining vehicle traction.

Another significant patent is the limited slip differential (LSD). This invention includes a driving plate, backing plates, differential gear assemblies, and a transmission assembly, all engaged within a sealed casing where fluid is pumped. The driving plate features pairs of communicated openings that interlock two gears of each gear assembly. As the plates rotate synchronously, the gear assemblies are alternately soaked in fluid, allowing it to pass among the gears to adjust rotational speed. If the rotational speed difference of the vehicle's axle shafts exceeds a certain threshold, the LSD applies at least one gear assembly to generate back pressure, effectively blocking fluid passage and limiting the rotational speed difference, thus achieving a limited-slip effect.
