AI Technical Summary
Existing power transmission systems in wheel loaders experience energy loss in neutral states due to clutches being disposed on the output side of planetary gear mechanisms and hydraulic motors, leading to inefficiencies in both low-speed and high-speed operations.
A power transmission device with a configuration that includes a planetary continuously variable transmission mechanism, a direct connecting mechanism, and clutches disposed between the input shaft and idler element, allowing for efficient power distribution through a direct connecting clutch and hydraulic pressure, and switching to a direct connecting mechanism for high-speed operations.
Reduces energy loss in neutral states by releasing clutches and optimizing power transmission efficiency across various speed ranges, enhancing overall operational efficiency in wheel loaders.
