Abstract

The invention discloses a power coupling device and a transmission system of a hybrid power vehicle. The power coupling device is arranged in the box body of a vehicle gear shifting box and occupies the space of the conventional hydraulic converter and reversing mechanism; the power coupling device comprises a motor, a planetary wheel system, a brake and a clutch, wherein the motor and the planetary wheel system are integrated; the motor comprises a stator and a rotor, and the rotor is connected with a sun wheel of the planetary wheel system; the power output end of the motor is connected with the gear ring of the planetary wheel system; the input shaft of the vehicle gear shifting box is connected with a planetary frame of the planetary wheel system; the power longitudinal gear ring is output to the vehicle gear shifting box; a brake is connected with the power output end of the motor and used for controlling the locking and loosening of the motor; and the clutch is arranged between the gear ring and the sun wheel and used for controlling the combination and separation of the sun wheel. Compared with the prior art, the power coupling device has a wide variation ratio range and a compact structure, fully improves the integration level of a power assembly system, and is convenient to transplant to platforms with different vehicle modes.

Description

technical field [0001] The invention relates to a hybrid electric vehicle, in particular, the invention relates to a power coupling device and a speed change system of a hybrid electric vehicle. Background technique [0002] At present, hybrid electric vehicles are divided into three types according to the different connection methods of the motor and the engine. One is a "series hybrid" vehicle that only uses the motor to drive the car and the engine is used to charge the motor. The "parallel hybrid" vehicle driven by power, and the third is the "series-parallel hybrid" or "parallel hybrid" vehicle that uses the above two methods. Among them, the "parallel hybrid" vehicle is difficult to arrange because of its complex structure and large axial dimension. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compact hybrid electric vehicle power coupling device. [0004] In order to solve the above-mentioned techni...
