Embodiment 1

[0042] like figure 1 As shown, the first embodiment provides an integrated power assembly, including: a motor and a reducer, the motor and the reducer are connected in transmission; the rotor shaft of the motor and the input shaft of the reducer are integrally formed to form an integrated shaft 100 .

[0043] In this integrated powertrain, the rotor shaft of the motor and the input shaft of the reducer are integrally formed to form an integrated rotating shaft 100. Compared with the powertrain in the prior art, the rotor shaft and the input shaft in this embodiment Made into one, the two do not need to be connected by other parts, eliminating the spline or flange connection structure used in the prior art to connect the two, and the input shaft of the reducer is directly driven by the rotation of the rotor 600 Rotation, so as to realize the direct transmission of power.

[0044] Since the rotating shaft 100 in this embodiment is integrally formed, it can avoid the efficiency ...

Embodiment 2

[0069] Embodiment 2 provides an electric vehicle, including: the integrated powertrain in Embodiment 1.

[0070] The electric vehicle includes an integrated power assembly, wherein the specific structure, connection relationship, and beneficial effects of the integrated power assembly have been described in detail in the above text, and will not be repeated here.

Abstract

The invention provides an integrated type power assembly and an electric vehicle, relates to the technical field of new energy vehicles, and aims to solve the technical problems that during the powertransmission process, the power assembly system of the electric vehicle can cause loss to power transmission efficiency and vibration. The integrated type power assembly comprises a motor and a speedreducer, wherein the motor is in transmission connection with the speed reducer; and a rotor shaft of the motor and an input shaft of the speed reducer are integrally formed to form an integrated rotary shaft. The electric vehicle comprises the integrated type power assembly. The integrated type power assembly and the electric vehicle can eliminate efficiency loss caused by spline connecting and can avoid vibration caused by spline matching.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an integrated power assembly and an electric vehicle. Background technique [0002] At present, the world is facing the crisis of energy shortage and air pollution. These two problems directly threaten the sustainable development of the automobile industry. [0003] With the development of low-carbon economy and technological innovation in the field of automobile industry, the new energy automobile industry is the main way for mankind to solve this crisis. Under this situation, my country's automakers have invested a lot of money in the development of new energy vehicles and have made great achievements. Nowadays, there are many types of new energy vehicles, such as: hybrid vehicles, pure electric vehicles and fuel cells car. [0004] Take pure electric vehicles as an example. Pure electric vehicles are mainly composed of three subsystems: electric drive system, ene...
