Abstract

The invention provides a hybrid power gearbox for a passenger car and belongs to the technical field of power transmission systems. The hybrid power gearbox comprises an engine, a motor MG1, a motor MG2, a planet row P1, a planet row P2, a brake B1, a brake B2 and a clutch. When the car travels at a low speed or at a reverse gear, the brake B2 is released, and the motor MG1 works; when the car travels at a medium speed, the clutch is disengaged, and the car is directly driven by the motors to travel; when the car needs to be accelerated urgently, the engine is started to drive the motor MG2 to generate power to the motor MG1, and the motor MG1 works; when the car travels at a high speed, the brake B1 is released, the clutch is disengaged, and the engine works independently; and when the car is decelerated, the motor MG1 can recover energy. By the adoption of the hybrid power gearbox, dynamic power shifting can be achieved, coaxial input and output are achieved, the transmission efficiency is high, the dynamic performance of the car can be improved to a great extent, and the fuel economical efficiency of the car is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission systems, in particular to a hybrid transmission for passenger cars. Background technique [0002] At present, energy shortage has become an important problem facing the world, and hybrid technology can effectively improve low-speed power output and fuel consumption of vehicles, and has become the development direction of the automobile industry. When passenger cars are driving on urban roads, they often work under low speed and start-stop conditions. Under low speed and start conditions, they can be driven by electric motors. Charging, which can greatly improve the fuel economy of the vehicle. [0003] In the literature on the design of hybrid transmissions, manufacturers such as Honda, Toyota, Geely and Corun have not realized the coaxial input and output mechanism of the transmission, and there will be a problem that the radial installation size is too large. This hybrid transmission...
