Abstract

In order to the solve the technical problems that in the traditional parallel hybrid power device, a power assembly is too large in axial size, large in weight, complex in machining process and poor in economical efficiency, the invention provides a hybrid power system based on an engine and double motors. An improvement is made on the basis of the traditional parallel hybrid power device, two motors are arranged at the tail end of an intermediate shaft of a gearbox, the two motors are connected with the tail end of the intermediate shaft of the gearbox by additionally arranging two meshing gear sets, the machining process is simple, and box type adaptation is wide. Compared with a traditional P2 framework, a motor with small torque and power can be selected, the axial size of the power assembly is reduced, and the whole vehicle is convenient to install.

Description

Technical field [0001] The invention relates to a hybrid power system based on an engine and dual motors. Background technique [0002] Hybrid vehicles combine the advantages of fuel vehicles and electric vehicles, and are energy-saving and environmentally friendly vehicles with the most practical development significance and industrialization prospects. [0003] Traditional parallel hybrid power devices are mostly based on the P2 architecture, that is, the motor is arranged between the clutch and the transmission. This structure requires the selection of a high-power and large-torque motor, which causes the axial size and weight of the powertrain to be too large. The development cost is relatively high; the machining process of the spline in the blind hole of the motor shaft that is connected to the main box with the traditional P2 structure is complicated, and the box type is not wide enough; and the power source of the traditional power take-off is mainly provided by the automob...
