Problems solved by technology
At present, the main test method is to test the durability of the electronic pump by starting and stopping the whole vehicle in the real vehicle state, but this can only be carried out after a complete vehicle control strategy, and the real vehicle test has a high risk factor, takes a long time, and costs a lot. huge
If only the durability assessment of the electronic pump is carried out without the operating environment of the powertrain, the assessment is of little significance

The invention relates to a start-stop durability test device for an electronic pump of an automatic transmission, comprising: a power assembly, a power assembly installation support, a real vehicle shock-absorbing rubber pier, a harness, an engine oil supply device, a transmission oil pressure measuring device, and a start-stop test device. For the control system, both ends of the powertrain are connected to the installation support of the powertrain through the real vehicle shock-absorbing rubber piers, the gasoline inlet of the engine is connected to the engine oil supply device through the gasoline pipe, and the start-stop control system is connected to the engine, transmission, electronic The pump is connected, the oil inlet and the oil outlet of the transmission oil heating device are respectively connected with the oil outlet and the oil inlet of the transmission through oil pipes, and the transmission oil pressure measuring device is connected with the transmission through a signal line. The invention can greatly reduce the risk factor, reduce the test cost and shorten the test time. The test device is stable and reliable in operation, easy to assemble and disassemble, reasonable in structure and low in cost.
Description
technical field [0001] The invention relates to a start-stop durability test device and a test method for an electronic pump of an automatic transmission, belonging to the technical field of transmission tests. Background technique [0002] The electronic pump is an essential part of the automatic transmission with start-stop function. The start-stop durability test of the electronic pump is a very important part of the new product development and design improvement of the automatic transmission. At present, the main test method is to test the durability of the electronic pump by starting and stopping the whole vehicle under the real vehicle state, but this can only be carried out after a complete vehicle control strategy, and the real vehicle test has a high risk factor, takes a long time, and costs a lot. huge. If the durability assessment is only carried out on the electronic pump unit without the operating environment of the powertrain, the assessment is of little signi...
