Description

Technical Field

[0001] This utility model relates to the field of gear fault diagnosis technology, and in particular to a gear fault diagnosis device for new energy vehicles. Background Technology

[0002] Gear fault diagnosis in new energy vehicles requires a combination of methods. Through preliminary inspection, professional testing, and targeted repair, faults can be effectively identified and resolved, ensuring driving safety. A sound level meter is used to measure noise in decibels, and the noise frequency components are analyzed using a spectral analysis. Broadband noise (such as high-frequency howling) may reflect deterioration of tooth surface roughness or poor lubrication. An infrared thermometer or thermocouple is used to measure the gearbox housing temperature. In cases of severe wear, localized temperatures may rise sharply. If the temperature near a bearing housing is abnormally high, it may correspond to wear on adjacent gears.

[0003] Previous gear fault diagnosis devices for new energy vehicles have the following drawbacks: 1. They are not convenient for analyzing and diagnosing gear faults by collecting vibration signals using acceleration sensors, thus hindering diagnostic accuracy. Furthermore, when not in use, their dustproof and impact-resistant properties are not significant, making them prone to damage. Therefore, those skilled in the art have provided a gear fault diagnosis device for new energy vehicles to address the problems mentioned in the background section. Utility Model Content
