Abstract

The invention relates to a dual-motor hybrid power coupler, which is provided with a brake B0 on an engine input shaft, a planet carrier connected with a planetary transmission gear set on the engineinput shaft, a sun gear and a large gear of the planetary transmission gear set are coaxially fixed and empty sleeved on the engine input shaft, and a gear ring of the planetary transmission gear setis connected with an output shaft; a brake B1 is arranged on an input shaft of the first motor, the input shaft of the first motor is connected with an idler gear through an idler gear, and the idlergear is meshed with a large gear of a planetary transmission gear set; a clutch is arranged between the primary driving gear and the input shaft of the second electric machine, the primary passive gear is coaxial with the secondary driving gear, and the secondary passive gear is identically sleeved on the input shaft of the engine and fixedly connected with the ring gear of the planetary transmission gear set. The invention has the advantages of compact structure and novel form, can realize deep hybrid power, and ensures that the engine and the electric motor always work in the optimal efficiency region through switching between a plurality of driving modes.

Description

Technical field [0001] The present invention relates to the technical field of hybrid power vehicles and their transmission systems, in particular to a dual-motor hybrid power coupler and a working method thereof. Background technique [0002] In order to cope with the increasingly severe energy crisis and environmental pollution, the state vigorously supports the new energy automobile industry. As a new energy vehicle technology solution with outstanding energy saving and emission reduction effects, hybrid electric vehicles are actively developed and produced by major automobile companies. Hybrid electric vehicles generally refer to hybrid electric vehicles, which use engine and electric motor as power source. Its working principle is: use electric motor to drive under low speed and start-stop conditions; use engine and electric motor under high-speed or high torque conditions Hybrid drive or engine direct drive; most hybrid vehicles can also use the motor to apply braking forc...
