Hybrid power system of engine integrated motor

Abstract

The invention discloses a hybrid power system of an engine integrated motor and relates to the technical field of automobile manufacturing. The hybrid power system comprises a motor connected with anengine, a flywheel assembly and a clutch, wherein the motor is provided with a motor shell, a motor stator, a motor rotor and a motor shaft which are sequentially arranged from outside to inside; themotor shell is connected with a motor end cover; the flywheel assembly is provided with a flywheel and a connecting shaft; and the connecting shaft is coaxially and fixedly connected with the motor shaft; the clutch is coaxially connected with the flywheel; the motor shaft and a crankshaft of the engine are of an integrated structure; and the connecting shaft and the flywheel are of an integratedstructure. Compared with the prior art, the axial size of the hybrid power system is shortened, the overall structure is compact, and the occupied space is small; and parts for transmitting power arefew, the structure is simple, the power loss is reduced, and the manufacturing cost is reduced. The motor rotor is directly mounted on the crankshaft with the integrated structure, so that the assembly is easier, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a hybrid power system with an engine integrated with a motor. Background technique [0002] The so-called hybrid vehicle generally refers to a gasoline-electric hybrid vehicle, that is, a traditional internal combustion engine and an electric motor are used as power sources. There is a patent titled "Hybrid Power System with Engine Integrated Motor" (the patent publication number is CN109318694A, and the publication date is February 12, 2019). The hybrid power system with integrated motor includes a motor connected to the engine and a flywheel assembly And the clutch assembly, the motor has a motor housing, a motor stator, a motor rotor and a motor shaft arranged in sequence from outside to inside, and the motor shaft is rigidly and fixedly connected to the crankshaft of the engine; the flywheel assembly has a connecting shaft that is coaxially and fixedly connec...

AI Technical Summary

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a hybrid power system with an engine integrated motor, which can solve the problem of the large radial runout of the motor rotor during high-speed rotation that accelerates wear, and the axial dimension of the existing hybrid power system with an engine integrated motor It is long and takes up a lot of space; there are many parts used to transmit power, the manufacturing cost is high, and the motor assembly is difficult
