Test device and method for automobile power assembly

Abstract

The invention relates to the technical field of new energy automobiles, in particular to a test device and method for an automobile power assembly. The device comprises a machine platform, a rotatingdisc disposed on the machine platform, and a rotating disc driving mechanism used for driving the rotating disc to rotate intermittently, wherein the rotating disc is provided with a motor clamp; a vibration detection mechanism disposed on the motor clamp; a clamp driving device used for driving the motor clamp to move; a no-load detection mechanism, a load detection mechanism, a torque detectionmechanism and a locked-rotor torque detection mechanism which are sequentially arranged around the rotary disc, wherein a controller is arranged on one side of the machine table. After the motor in the automobile power assembly is clamped once, motor no-load, motor load, motor torque, motor stalling torque and motor vibration of the motor are automatically detected, a detection report is automatically generated after detection, labor investment is reduced, detection is accurate, and production requirements are met.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to testing equipment and testing methods for vehicle powertrains. Background technique [0002] In recent years, with the continuous maturity of the development of electric vehicles, the use of electric vehicles will become more and more popular, and the resulting test problems of electric vehicle powertrains will also attract more and more attention. In the existing technology, in the content of electric vehicle powertrain testing, the test of the motor has always been the key point of the vehicle powertrain test. The motor test system is generally set by the operator to set the measurement parameter value to simulate the various characteristics of the motor in real time. Experiments, such as motor no-load characteristic test, motor load test, motor torque, stall torque measurement, motor vibration test, etc. [0003] However, the existing motor detection devices in th...

Problems solved by technology

[0003] However, the existing motor detection devices in the automotive powertrain cannot simultaneously test the motor no-load characteristic test, motor load test, motor torque, stall torque measurement, motor vibration test, etc., and need to replace different equipment and install the card separately. Testing, the testing of the motor requires a lot of manpower, which is not only inefficient, but also causes differences in test results due to the different operating proficiency of the testers and the different loading methods; in addition, most of the processing of test data is currently manual. Processing, the processing of different experimenters will also lead to differences, which cannot meet the production needs
