Latest Patents
One of Liang-Fei Xu's latest patents is an electric wheel assembly applicable for a parallelly mounted dual-tire wheel, axle, and vehicle. This invention includes a wheel and support axle assembly, an internal-rotor hub motor, a planetary gear reducer, and a brake system. The design features a planetary carrier connected to a hub, which is in turn connected to a spoke and a rim. The wheel support axle passes through a rotor sleeve and is equipped with a hub bearing to support the hub and the entire wheel. The sun gear at the end of the rotor sleeve serves as the power input for the planetary gear speed reducer, while the planetary carrier acts as the power output. This innovative design achieves a relatively high transmission ratio with a compact axial length.
Another significant patent involves a method for diagnosing degradation of a fuel cell stack. This method includes qualitatively determining the degradation type of the fuel cell stack based on its voltage-current curve. It also involves quantitatively measuring parameter values of individual cells and determining their degradation degrees. By assessing the uniformity of degradation among the cells, this method provides insights into the overall condition of the fuel cell stack.
