Abstract

The invention provides a transmission device for a longitudinal-engine rear-drive hybrid vehicle. The transmission device comprises a first motor (EM1), a second motor (EM2), an engine, a planet gear coupling mechanism and an input shaft and is provided with a first brake (B1), a second brake (B2), a first clutch (C1) and a second clutch (C2), and the first motor and the second motor are connected with the planet gear coupling mechanism through a first speed reducing gear pair and a third speed reducing gear pair respectively to achieve multiple pure electric and hybrid power driving modes. The transmission device for the longitudinal-engine rear-drive hybrid vehicle is compact in structure and can be matched with engines with different displacements, the motor torque requirements are lowered, and the manufacturing cost is reduced.

Description
