Title:
THREE-GEAR PARALLEL-SHAFT DUAL-MOTOR THREE-PLANETARY GEAR SET HYBRID POWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/041545
Kind Code:
A1
Abstract:
A three-gear parallel-shaft dual-motor three-planetary gear set hybrid power system, comprising an engine (100), a flexible connector (200), a housing (300), a central shaft (326), a first hollow shaft (324), a second hollow shaft (319), a front output shaft (314), a rear output shaft (313), a first planetary gear set, a second planetary gear set, and a third planetary gear set. The central shaft (326), the first hollow shaft (324), the second hollow shaft (319), the front output shaft (314), the first planetary gear set, the second planetary gear set, the third planetary gear set, a first motor (402), and a second motor (401) are all disposed in the housing (300); the first hollow shaft (324) is sleeved on the central shaft (326); and the second hollow shaft (319) is sleeved on the first hollow shaft (324). The present invention solves problems in existing hybrid powertrain systems such as low maximum motor rotation speed, large peak torque, high motor cost, large axial length, high layout space requirements, and poor vehicle adaptability.
