DUAL-POWER DRIVE SYSTEM CONFIGURATION FOR ELECTRIC TRACTOR

WIPO Patent Application WO/2020/143278

A1

A dual-power drive system for an electric tractor, comprising a rear power output shaft PTO transmission case (2), a rear axle differential (3), a rear speed reduction transfer integrated case (5), a front axle driving motor (6), a front axle differential (8), a front speed reduction case (10), and a rear axle driving motor (11). An output shaft of the rear axle driving motor (11) is connected to an input shaft of the rear speed reduction transfer integrated case (5), and an output shaft of the rear speed reduction transfer integrated case (5) is connected to an input shaft of the rear axle differential (3) by connecting a rear axle clutch (4); an output shaft of the front axle driving motor (6) is connected to an input shaft of the front speed reduction case (10), and an output shaft of the front speed reduction case (10) is connected to an input shaft of the front axle differential (8) by connecting a front axle clutch (7). The dual-power drive system can satisfy larger power output requirements; operation modes such as front-drive, rear-drive, and four-drive operation are converted for agricultural working conditions, and the slipping condition of field operation is reduced.
