All EV systems of new energy vehicles must be tested to be qualified for delivery, and manufacturers have an increasing demand for testing. After EV system meets the requirements of delivery, EV system must be tested for delivery. According to the production demand of each pure electric reducer (EV), the time and process of the whole production beat and detection beat, the production line is directly connected with the test. Pure electric speed reducer (EV) must ensure the performance of gearbox and product quality in factory inspection, so it is very important to test and analyze the performance of the speed reducer strictly. According to the NATIONAL standard QC/T 1022-2015 "Technical Conditions of Reduction Gear Assembly for Pure Electric Passenger Vehicles" and referring to other national standards and various assembly testing standards, the test purpose of the pure electric reduction gear (EV) is to determine and test the factory qualification of the pure electric reduction gear (EV).Retail price0.0元Market price0.0元Number of views:1000Product serial numberQuantity-+Stock:0Category返回列表1Product AdvantagesParametersTechnical Parameter

EOL4000 -- EV Gearbox online test system -- Topology
The eOL4000-EV transmission on-line test system is modular and integrated, with ergonomic operation and manual/automatic mode control. It consists of three parts: mechanical system, system up-down flow control system, guarantee system, electrical system and upper computer software system.
Mechanical system: the whole mechanical platform, loading equipment, shafting connection part and other equipment composition.
L System up-down flow control system: EV gearbox tools under test, EV gearbox, transport roller way /AGV trolley in front of the roller way, positioning and clamping system, automatic completion shafting, water, electricity, oil and other matching system and other equipment composition.
L Guarantee system: oil filling system and other equipment composition.
L Electrical system: drive, load control, real-time data acquisition system of sensors (torque, speed, vibration, temperature), data acquisition, alarm system, NVH vibration, noise, serial scanning system and other equipment.
L Software system: Upper computer test software is divided into data acquisition and communication module, data acquisition and setting module, data real-time exchange and control module, and data processing module according to the system. The whole process control program is adopted to complete the product qualification evaluation through data acquisition, control and processing, and the data link of the entire production system is complete through the matching between the EOL4000 production line workstation system and the production management system, so that the original data of the production inspection system can be traceable.

EOL4000 - EV gearbox online test system - Key features
01 Functional Modularization
The whole design of the platform is adopted, and the modular component combination is adopted inside, which is convenient for the platform combination and maintenance.
02 Advanced means of measurement
Advanced real-time measurement and control system is adopted, including input electrical parameters test, rotational speed torque test, etc. The sampling rate of torque and rotational speed is up to 1000Hz, which meets the requirements of high precision and rapid response of the test system. Moreover, transient data and eigenvalue data are provided to facilitate the comprehensive analysis of test process data by software in the later stage.
The test items are complete
According to the test requirements stipulated by the national standard, the test items can be added or subtracted according to the configuration module, which can meet all kinds of ex-factory test items
04 Motor load
Using asynchronous motor/permanent magnet motor as participants gearbox drive and load, change the traditional way of load and improve the system of dynamic measurement of torque and rotational speed range and precision, improve load (is/reverse, the drag), shorten the response time of load, which can realize arbitrary load curve of load, high simulation of the motor/drive real-time operation condition.
System up and down flow control system.
EV gearbox is pre-installed with the lifting device to the pre-installed area, and the tested parts are transported to the test bench through the transport roller /AGV trolley mode, and to the test bench through the front roller table, and then the fixture is fixed through the positioning clamping system. The system automatically completes the alignment of shafting and oil circuit, thus completing the docking process of tested parts. After the test is completed, complete the offline process according to the on-line process inversion procedure.
06 Humanized design
Professional factory EV transmission test bench, fixture with fast clamping docking functions, and convenient loading and unloading can be adapted to different specimen installation, joint vibration analyzer can complete transmission and harshness (NVH) testing of the motor, system controlled by computer cabinet + cantilever mode operation, and can complete all units are complete test operation layout.
Customized test software
The EV gearbox factory test system test software developed by Sichuan Chengbang Software DEVELOPMENT team designed the software according to the test process, classified the software interface and control process, reduced repeated tests, and greatly improved the work efficiency of the test personnel. It also has the functions of real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, qualification determination, report export and so on.
