Embodiment Construction

[0014] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the motor integrated structure includes a motor drive shaft 1, two bearings 2, an integrated housing 3, a motor stator assembly 4, a motor rotor assembly 5, a motor resolver stator 6, a motor resolver rotor 7, and a resolver rotor Boss 31 etc. are installed.

[0016] see image 3 , the integrated housing 3 is bowl-shaped, and there is a motor drive shaft installation hole in the center of the bottom. The double-row bearing 2 is assembled into the motor drive shaft installation hole by shrinking or cold pressing. in.

[0017] see figure 2 with Figure 4 , One end of the motor rotor shaft 1 is processed into an inner spline 11, and the other end is processed into an outer spline 12, and the power is transmitted to the engine and the transmission through the spline connection respectively. The middle part of the ...

Abstract

The invention aims at providing a motor integrated structure of a hybrid electric vehicle, which comprises a motor drive shaft, a motor stator assembly, a motor rotor assembly, a motor revolver stator and a motor revolver rotor, wherein the motor drive shaft, the motor stator assembly, the motor rotor assembly, the motor revolver stator and a motor revolver rotor are integrated and assembled in an integrated shell and are respectively connected with a vehicle engine cylinder and a transmission installation shell through installation terminal surfaces at two sides of the integrated shell, one end of the motor drive shaft is connected with an engine through a vehicle dual-mass flywheel by adopting an external spline, and the other end of the motor drive shaft is connected with a transmission by adopting an internal spline. The motor integrated structure has the advantages of compact structure, convenience for installation, small arrangement space and the like, and solves the problem that motor assemblies are arranged in a limited space of an integral vehicle forecabin.

Description

technical field [0001] The invention belongs to the field of motor structure design, and in particular relates to a motor integrated structure of a hybrid electric vehicle. Background technique [0002] Nowadays, the problems of environmental pollution and energy shortage are becoming more and more serious, and the requirements for reducing fuel consumption and improving exhaust emissions of automobiles are becoming more and more urgent. Therefore, electric vehicle technology has gradually become the trend of automobile research and development. However, due to the immature battery technology at this stage, hybrid vehicles are used as a transitional product between traditional vehicles and pure electric vehicles. The current relatively common hybrid electric vehicle scheme is to combine the engine with the electric motor and the generator. How to realize the power connection and power distribution between the hybrid electric vehicle engine, the electric motor and the generat...
