Abstract

The invention consists of a motor, three clutches, three brakes, a pair of constant mesh gears, four front and back planet rows, an output shaft and an engine. The output shaft of the motor is connected with the front and back solar wheels. The engine is connected with the driving gear via the clutch of the engine, and the driven gear is integrated with the front planet frame and the back gear ring. The output shaft is connected with the front gear ring or the back planet frame via the front gear ring clutch and the back planet frame clutch. Using the different state combination of three clutches and three brakes can realize many kinds of working modes of the motor vehicles.

Description

Technical field [0001] The invention belongs to the technical field of automotive power components, and in particular relates to a double-row planetary gear electromechanical power coupling assembly for a hybrid electric vehicle. Background technique [0002] On the one hand, due to the pressure of energy and environmental protection, on the other hand, due to the power battery technology and fuel cell technology that pure electric vehicles strongly rely on are difficult to break through in the near future, hybrid electric vehicles have attracted people's attention as a transitional solution to comprehensive problems. A hybrid vehicle refers to a vehicle that uses two or more energy stores, energy sources or converters as driving energy. The current common solution is to use a combination of an engine and a power battery, and the power battery provides auxiliary power or all power through the electric motor. driving force, and also enables recuperation of braking energy.
