Abstract

The invention discloses a test bench and method for the slurry environment simulation of a start and stop motor for a vehicle, and the test bench mainly comprises a slurry environment box and a supporting shaft. The interior of the slurry environment box is provided with a storage cavity for storing slurry saline water, a flying wheel, and an output shaft gear of the start and stop motor. The supporting shaft is disposed on the slurry environment box, and is used for installing the flying wheel. The test bench is simple in structure, is low in manufacture cost, can test the failure cause of the start and stop motor under the condition of truly simulating the slurry environment of the whole vehicle, is of great significance to the improvement of the design of the bearing sealing of the start and stop motor and the abnormal sound of the motor, and provides important reference data for improving the customers satisfaction degree and improving the brand value.

Description

technical field [0001] The invention belongs to the technical field of testing. Specifically, the invention relates to a mud environment simulation test bench and a test method for a vehicle start-stop motor. Background technique [0002] After the car start-stop motor works for a long time, many failure modes are abnormal noise failure. However, due to the special structure of the start-stop motor, it needs to be directly meshed with the flywheel of the automobile engine, so that the meshing and bearings are directly exposed to the flywheel of the engine and cannot be sealed. Therefore, the failure mode of the abnormal sound of the start-stop motor mainly comes from foreign matter such as mud, iron filings, and oil stains at the meshing point of the flywheel. [0003] At present, when the vehicle rotating motor (start-stop motor) simulates environmental tests such as splash and mud, the bench production uses the power cabinet to control the start and stop of the motor, and...
