The invention provides a hybrid power device. The hybrid power device comprises an engine, a motor, a first main speed reducer driving gear, a second main speed reducer driving gear, a main speed reducer driven gear, a first speed change mechanism, a second speed change mechanism, an intermediate drive gear and an electromagnetic clutch. The engine drives the main speed reducer driven gear through the first speed change mechanism and the first main speed reducer driving gear; the motor drives the main speed reducer driven gear through the second speed change mechanism and the second main speed reducer driving gear; a driven gear of the first speed change mechanism is selectively connected with the motor through the intermediate drive gear and the electromagnetic clutch, and the intermediate drive gear is a gear set formed by three gears. In parking, the electromagnetic clutch is engaged, and power of the engine is transferred to an input shaft of the second speed change mechanism through the driven gear of the first speed change mechanism and the intermediate drive gear to drive the motor to generate power, so that a function of power generation in parking is realized.
Description
technical field [0001] The invention relates to the technical field of vehicle drive, in particular to a hybrid power device and a corresponding parking power generation method. Background technique [0002] A hybrid power device in the prior art is formed by adding an electric motor to the transmission with minimal changes to the transmission. The electric motor is connected with the driven gear of the final drive through a fixed-ratio reduction mechanism or a two-speed transmission mechanism, thereby avoiding modification of the components before the output shaft of the transmission, and ensuring the maximum utilization of the main components of the existing transmission. However, there is a functional defect in this hybrid power device, that is, the electric motor cannot be driven by the engine to generate electricity when parking, so it is difficult to ensure the power balance of the power storage device. Contents of the invention [0003] The object of the present in...
