Abstract

The invention discloses a power coupling device for a hybrid power vehicle, comprising a motor stator and a motor rotor assembly, wherein the motor rotor assembly is matched with an input shaft of a speed changer and tightly and fixedly connected with an engine crankshaft; a rotary transformer rotor is arranged on the motor rotor assembly and corresponds to a rotary transformer stator arranged on a motor stator shell; a driven disc is connected with the input shaft of the speed changer; a baffle disc is connected with the motor rotor assembly through rivets penetrating through the driven disc; and the driven disc is provided with four radially vertical long holes, and four damping springs are respectively arranged in the four long holes and positioned between a rotor bracket and the baffle disc of the motor rotor assembly. The invention has simple and compact structure, effectively utilizes the space and greatly shortens the axial length, thereby solving the technical problem that a power assembly of the hybrid power vehicle is difficult to transversely place; and in addition, the invention simplifies the structure, reduces the cost and prevents the resonance from being generated by effectively alleviating the dynamic loads generated when the rotating speed of a transmission system is rapidly changed.

Description

technical field [0001] The invention relates to automobile parts, in particular to a power coupling device of a hybrid electric vehicle. Background technique [0002] Facing the energy crisis and environmental deterioration, energy conservation and emission reduction has become one of the most concerned topics in various countries. During a period when electric vehicles have not been widely popularized, hybrid vehicles will become the most ideal vehicles to replace conventional energy vehicles, and major automobile companies have stepped into the ranks of developing hybrid vehicles. Because of the functions of idling start-stop, acceleration assist, braking energy recovery, and pure electric driving, hybrid electric vehicles not only have strong power performance, but also have a high fuel-saving rate. [0003] For a hybrid vehicle with a single motor, the power source includes an engine and a motor. Reasonable allocation of the power of the engine and the motor to make it ...
