Description

technical field [0001] The invention relates to a new energy vehicle motor testing device, in particular to a fast clamping device for new energy vehicle motor testing. Background technique [0002] The dynamometer is also called a dynamometer, which is mainly used to test the power of the engine, and can also be used as a loading device for a reducer and a gearbox to test their transmission power. It is mainly divided into a hydraulic dynamometer and an eddy current dynamometer. , Electric dynamometer, among them, the control performance and response speed of the eddy current dynamometer are obviously better than the hydraulic dynamometer, but the hydraulic and eddy current dynamometer are pure energy consumption test equipment, which do not meet the needs of modern energy conservation and environmental protection. It is bound to withdraw from the market. With the widespread attention of new energy and new power, electric dynamometer is favored because energy can be fed bac...

[0002] The dynamometer is also called a dynamometer, which is mainly used to test the power of the engine, and can also be used as a loading device for the reducer and gearbox to test their transmission Power, mainly divided into hydraulic dynamometers, eddy current dynamometers, and electric dynamometers. Among them, the control performance and response speed of eddy current dynamometers are significantly better than those of hydraulic dynamometers, but hydraulic and eddy current dynamometers are Pure energy consumption test equipment, which does not meet the needs of modern energy conservation and environmental protection, will definitely withdraw from the market. With the widespread attention of new energy and new power, electric dynamometers are favored because energy can be fed back to the grid, energy saving and environmental protection, especially in today's In the era of very high product performance requirements, fast and convenient testing has become the primary requirement for improving production efficiency and reducing labor intensity

[0003]The existing new energy vehicle motor test system mainly uses the electric dynamometer test system, which uses AC frequency conversion feedback loading, and the loaded energy is fed back to the grid through the AC load motor , is widely used in the testing of various rotary equipment such as motors, generators, pumps, etc. The system is composed of the motor under test, the loading motor and various detection and control devices, and is used to test the speed, torque performance, and speed of the equipment under test. Response and torque ripple overshoot and other performance indicators provide factory inspection data for the use of the motor, but in the existing test system, the clamping device is installed by bolt connection, which cannot be automatically centered, and the installation and clamping takes a long time and the efficiency is low , high labor intensity, and high requirements for mechanical processing, hindering the popularization and use of motor test systems
