Document Type and Number:
WIPO Patent Application WO/2024/051371
Kind Code:
A1
Abstract:
Disclosed in the present invention is a variable-speed transmission system for a multi-gear hybrid electric vehicle, comprising an engine, a first motor, a second motor, an input shaft, an output shaft, a first countershaft, a second countershaft, and first, second, and third synchronizers. The input shaft is connected to the engine, and the first and second countershafts are respectively connected to the first and second motors; the input shaft is connected to the first synchronizer and is sleeved with first and second gears; the output shaft is connected to the second and third synchronizers and is sleeved with a plurality of gears; the first countershaft is connected to a first transmission gear, and the first transmission gear is selectively meshed with one gear sleeved on the output shaft; the second countershaft is connected to a plurality of second transmission gears, and the second transmission gears on the second countershaft is selectively meshed with the gears sleeved on the output shaft; and the first gear or the second gear are respectively meshed with the gears on the output shaft and/or meshed with the second transmission gears on the second countershaft. The present invention can achieve gear shifting without power interruption, many gears available for shifting are provided, and the use cost is low.
