AI Technical Summary

Problems solved by technology

However, if the multi-stage transmission is used, the matching performance is poor, and the shifting methods are mostly theoretical analysis, and the actual verification effect is poor
Clutchless gear shifting mode, motor control is difficult to achieve
That is to say, it is difficult to match the motor and the transmission in the electric vehicle powertrain in the prior art

Embodiment Construction

[0022] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0023] As shown in the figure, the driving motor 1 shaft end has a flywheel disc 10, the clutch cover 8 is fixed on the flywheel disc 10, and the clutch driven disc 9 is installed between the clutch cover and the flywheel disc, and is sleeved on the transmission shaft. The structure after assembly is as Figure 1 .

[0024] The transmission 7 is an electromechanical automatic transmission with two forward gears: a low-speed climbing gear and a driving gear. The clutch actuator 2 and the shift actuator 3 are integrally installed on the transmission body, and a shaft speed sensor 4 is installed on the transmission 7 for detecting the speed of the first shaft of the transmission and the speed of the clutch driven disc 9 . The vehicle speed sensor 11 is installed on the differential case an...

Abstract

The invention relates to a power assembly of an electric automobile, comprising a drive motor (1) and a gear box assembly (7), wherein the drive motor (1) is a permanent magnet synchronous motor; the gear box assembly (7) comprises a two-gear electronic control mechanical gear box which has a climbing gear and a running gear; and the drive motor (1) is matched with the two-gear electronic control mechanical gear box.

Description

technical field [0001] The invention relates to the technical field of auto parts production and manufacturing, in particular to a power assembly of an electric vehicle. Background technique [0002] The development of new energy vehicles is getting faster and faster, and the development and popularization of electric vehicles has been paid more and more attention. The country has recently issued a number of measures to encourage electric vehicles to promote the development of electric vehicles. The performance requirements for electric vehicles are getting higher and higher, and the development requirements for components of electric vehicles, especially the powertrain, are also getting higher and higher. [0003] At present, in the known technology, the deceleration mechanism of electric vehicles is mostly single-stage speed ratio, the performance of the whole vehicle is limited, and higher requirements are put forward for the design and manufacture of the motor. Car perf...
