Abstract
A gearbox comprises a differential gear train. The differential gear train comprises a ring gear assembly, a sun gear assembly, and a planetary carrier assembly connected to a planetary gear mechanism. The planetary carrier assembly comprises side plates. The side plates combine with gears to form high-pressure volume units and low-pressure volume units, and a throttle channel is connected between two volume units. The high-pressure volume unit is constructed in a meshing zone of the gears. All high-pressure volume units are connected and communicated with each other by means of a high-pressure oil channel on the planetary carrier assembly. The gearbox can reduce the volume of the high-pressure volume unit, simplify the structure and process, and improve the transmission efficiency and reliability.
